I had around 500 RWHP (at 6200rpm)/ 480 RWTQ(4700 RPM) running 12lbs on my old S trim, so I think that your setup with 8 pounds is putting down some very nice numbers. Congrats!

Thanks Aaron - at the moment only 5/6 pounds (controlled via RPM limit) until I can get a wideband hooked up. TBH I dont plan on touching the spark (yet). I'm also spraying 50/50 alcohol on a 2-stage controller that kicks in at around 5psi and then doubles flow at 10psi. Heads are CNC'ed LT4 heads, cam is a 236/246 with 1.6 rockers on a 115 LSA.

The YSi fits nice on a L98 and Greg has all the brackets you need. My YSi setup (LT1) was more complicated due to the sheer size of the blower and the location of the accessories compared to the L98.
Nothing quite like the surge of a blower, very controllable on the street and there when you need it.!!

Go have a look at the moates.net web site. They have a great OBD1 to USB cable adapter. You can use TTS Datamaster or Tunerpro (plus a few others) to capture the ALDL data. However I'm not sure if anything exists to exercise the car components like a Tech1.

I get a few hundred knock counts when I start the car, zero afterwards (even on high spirited scan runs). Here is what I have done so far to tune my car. Baseline tune from Blowerworks - got me close. (i.e. car started, idles, ran reasonably well). My car is very custom, lots of CNC work, so mailorder tune will be close but not perfect. Then used TTS Datamaster to do a ton of scans - my test drives were a whole combination of driving at certain speeds with the throttle held steady so I could see what was happening in specific areas with INT and BLM. Used VE master to get the tune roughly close to perfect then smoothed the table a little for cell transition. Lots of help from Greg at B/W. To be honest, the power stuff is easier because there are only a couple of tables. I usually make sure everything runs a bit fat (above 900mv O2) before I get to the dyno with a WB, and I limit the engine to less than about 4800 RPM. Even then the first few times I go into PE (i.e. above about 60% throttle) I double check for knock before I get on it some more. The hardest stuff (for me) has been tuning low down - I still have a rich condition at idle and a mild lean tip-in, but like I said it's all about carefully checking the scans - really carefully because you can miss a ton of stuff. I haven't had time to really get the tip-in perfect but I have driven 250 miles in the last 3 days and I love the way the car drives. When I get the dyno and install the wideband I'll tweak idle, tip-in and PE. Should be a monster! If you want, I'll take a look at your datamaster scans and I can express an opinion!

Posted here - I guess the topic covers all 'Vettes.
I want to 'install' a wideband setup in my car. However - too much choice and too many combinations! I like the idea of wideband sensors that are installed permanently and provide a narrowband feed to the ECM, but I'm worried about calibration. I like the idea of having dual sensors rather than one. I like the idea of an in-car gauge that has an analog feed to a datalogger But - too many datalogging options! I'm not sure if any of my 'likes' are good ideas or not.. What are the guru's running?

Absolutely - very important to match up what was happening on the road with what you are seeing on the scan. E.g. find the key points on the scan where you accelerate. Watch the O2 mv and INT and BLM and Cell #s very carefully as you go through the scan - be suspicious if the O2 mv's stop cycling low/high/low and stay either at the high end (900 ish) or the low end (50 ish)

For a ZF6, some will say remove the hood and pull motor and tranny together.
For mine, I first separated the transmission from the bellhousing, then pulled the engine and bellhousing together. Key tips/steps for me were: 1. Support the transmission with a tranny jack and remove the C beam and driveshaft 2. Lower the rear of the transmission so you can see all the tranny to bellhousing bolts (and the shifter is clear), support the rear of the motor with another jack, then separate the tranny from the bell housing. Note that the engine mounts will be fine if you do this. 3. Using a load leveler, pull the motor and bellhousing together. It will be easier if you remove the balancer when doing this. Sounds easy - first time it isnt, but it gets easier.

I've been there - nothing ever seems to go right. Does it seem off on your laptop or when you drive it?
If you think its completely out of whack, go back to where you started and get a gut check - is the car better or worse. Forget the scanning for a bit and drive that sucker and figure out where you want to improve it. Trying to get 128/128 on any car is chasing your tail - I try and get within a few percent (e.g. in the range of 123-133 each side). So many factors will affect the BLMs day to day (fuel quality, temperature, altitude..).

Could be a number of things - even a bad batch of fuel in the last fill up. Noisy/loose rocker or exhaust leak can cause knock.
Personally I would go back to the original tune (assuming it basically worked) and check for knocks. At least then you know it's the tune and not any other factor. If you confirm it is in the tune, in my opinion it is probably a lean condition - check what's happening when it knocks, e.g. are you accelerating or lifting off the throttle, is it a cell transition thing (i.e. VE table not very smooth) etc.

Yessir. Plenty of debate on the topic of using stock O2's for tuning, but you can definitely tell if something is trending lean or rich. You'll see the O2's cycle between 0 and about 950 mv as the car runs - this cycling is normal. At the low end it's lean, at the high end it's rich. Exact AFR for each millivolt reading might be car and brand specific, so you cant read an AFR from it. On mine, in the scan I could see the O2's cycling at idle and then they would peg at less than 50mv for a number of scan records when I trid to move away from a stop - definitely a lean tip in.

Wideband bung and meter/logger being installed in a couple weeks so I can go to the dyno and can monitor things on a daily basis as the weather changes. To diagnose my tip-in issue I looked at my O2 readings - while they are not very accurate in terms of AFR I could see that it was trending very lean (i.e. less than 50mv both sides for about a second) so I was able to richen up the VE table under 1100 RPM (including down to 600) to improve things.

Hi Brian - the tune is excellent for power and general drivability (Blowerworks are awesome). I had (have) split BLMs which was impacting tip-in and decided to fix it myself. Now fixed (although I've had to be a little creative). Car is not only great for daily driving but is a complete monster when I get on it. Just need to dial in my PE on a dyno - currently running 4800 RPM limit and 26 degrees max spark and a little rich for safety. Purpose of the post was to create a little amusement for the gurus

All easy fixes but all brought me a WTH? DOH! moment..
Yes, running too lean will make the engine run hot. Yes, too much spark advance at idle will make the car hard to start. Yes, the O2 sensors will give you a really good idea whether you are lean or rich at tip-in. Stop guessing! Yes, a bigger cam will operate at a different MAP at idle. Oh BTW, this also means that the fuel pressure will be higher at idle. Oh, the fun of tuning...

I checked my Chevy Fuel Injection bible (by probst) and he says that the knock sensors are not used in open loop. Having said that, lets fix the obvious things first and change out that knock sensor. On the tune, if the base tables are out then things will always improve when it goes into closed loop. I've been chasing the opposite situation this last couple of weeks where it runs great in open loop but like crap in closed loop - mine is an issue with the large cam messing up the O2 sensor readings. My point is we should scan the car to see what's going on in open loop and closed loop (Also see your PM's)

It was a big day for me today - I managed to get some time away from work and I got the tune to a point where I could attempt some full throttle bursts up to around 4500. All I can say is the beast is alive and it's very hungry...

So you definitely seem down on power under 2000rpm? You should be able to light up the tires at will at low speeds.
Can you describe the problem at little more? For example, what speed/gear you are testing at - can you burn the tires at a stop light? What happens when you jab the throttle - does the car pause as if it's thinking what to do next (dead spot - too lean), or does it stumble along slowly, maybe with some herky-jerky and black smoke? (too rich). Is there any knock/spark retard? You said you have PE disabled, why is that? Do you have a wideband? Need info!

Congrats on passing emissions - always a huge milestone with a modified engine.
I need to correct what I said above - it reads weird. My suggestion is to take the lower end of your AE table and add 10% to the values to increase the pump shot at initial throttle tip-in. You didnt say if you are having drivability issues with the larger TB?

Raining today thru Friday, so the test and tune is on hold for a while (reason? Nitto NT01's on the rear). Probably just as well, need a break to clear my head of VE table smoothing.
Probably going to have a desk day - lots of admin to catch up on at work. Andy - (95Vette) - I'll call you later. Have a good day folks!

Looks like I have a few tables in my tune ($DA2 - 1992 LT1) that correlate TPS and AE. I have a stock TB but a CNC'ed intake.
1. AE Delta Map enable threshold vs TPS (this is the same as the stock table) 0% 3.13 12.5% 2.81 25% 2.5 37.5% 2.5 50% 2.5 2. AE Delta TPS PW Factor (this is the same as the stock table) Pulse 1 = 3.98 Pulse 2 = 2.00 (all other pulses are set to 0) 3. AE vs. Differential TPS I run the stock table except for about 5-10% higher at TPS 37.5% and above Dont ask me the science behind my tables - I had a lean stumble (plus some knock retard) when I first purchased the car, which only happened on mid-throttle freeway on-ramps. and I messed around with the larger settings on AE vs. Differential TPS to fix it. As for your table, it looks like my table #1 above. Since you have a completely different intake I wouldnt recommend using my settings, but assuming you are trying to fix a lean tip-in issue (i.e. stumbling off the line) I would personally add about 10% to your table (smaller values) to see if it improves. Probably gonna be trial and error unless you can find someone who has tuned a L98 with a 58mm. I dont know if this helps, but good luck! Andy

Hi Brian, 1992 is a speed density car so no MAF. I deal with boost in the PE vs. RPM tables. Kind of pluses and minuses on a 1992. I'll probably upgrade to a FAST in the spring - all this constant driving/scanning and table adjustments are killing me!

Hope to make more progress on the build today - if things go well I could be taking the first test drive tomorrow.
Have a good weekend!

AE (otherwise known as pump shot) is to add a small pump of extra fuel when the throttle is opened rapidly - you have to play with this for larger tb's. It provides a 'bridge' of fuel between constant throttle position and PE. You will know if it's working because it comes into play if you suddenly jab the throttle about halfway- too lean or rich and you'll hesitate or stumble, just right and you get a nice surge forwards. PE comes into play at full throttle and is when the BLMs get turned off. This is what you play with to get power at the dyno.

I'd be a happy man if all my BLMs and Integrator values were as close as yours. On my last tune I had a ton of cam surge / reversion issues that meant I was always chasing a moving target. For true drivability I ended up getting the BLM's close enough (within 3-5) and then focusing on AE and PE tables (since that's where the fun is!).
I dont know if you have AE on yours. For some additional reading you could try going to thirdgen.org and camaroz28.com - search for your PCM type - both these sites have busy PCM tuning conversations.

Hi Tony - I would not be too concerned at this point. Tune for full coolant temperature first, then make adjustments to the lower temperature scenarios if you have time later. Engines behave differently at different temps hence the large number of coolant related tables.

Andy - Autozone have them. For LT engines it's basically a plastic sleeve you slip over the fuel rail lines and pull back into the flexible lines - it is so easy you'll wonder why they put it on a Vette! (literally 10 seconds to disconnect each line).

Hi Brian, It's a fully forged/built 383, front and rear internally balanced. LT1 bottom end, LT4 top end, extensively CNC'ed. The cam is 236/246 with a 115 LSA and 0.6" lift. 9:1 CR. On the engine dyno it made 430 crank horsepower and 400 ft-lbs tq. Stage 3+ SPEC clutch, superdamper with 8 Rib pulley. V7-YSi supercharger pulleyed for about 10-12 pounds (we'll see what happens!). 2-stage alcohol injection. Going to be fun! Andy

Finally got the car to a point where I could test-fire the engine. Still have a ways to go, tidy up looms etc before I can take for a drive and start tuning. However she fired on first turn of the key.
YSi pulley not hooked up yet - that will add some more noise... Turn the volume up - this one is with straight pipes! YSi Startup

Click on the attached link and then click on 'play' - my son's car is the black S14 with red hood, featured between 00:55 and 1:24.
Enjoy! Video

Morning Gurus - last day of the quarter for me and one of my SOB customers just dumped a list of last minute terms and conditions for the contract - once our legal comes online today is going to be a nightmare....
Kids grow up fast - mine are 21 and 22. Look out for my son's video in the 'drifting' thread that I'll post in a couple minutes.

See my post in your other thread - if you already have a removable chip/socket you can use that as a source for your bin. If you dont have a removable chip, get a chip adapter kit from Moates (you'll need it anyway even with an APU) and a stock bin from the moates site.
If you want a mini-tutorial on burning chips just PM me and I'll be happy to spend some time on the phone with you.

First of all, investigate the IAT reading. If the sensor is disconnected the PCM will be doing some weird stuff with fueling and spark. I dont know where the IAT is located in the L98, possibly in the intake pipework before the throttle body.
There is a table that needs modifying for the injector constant. I think you also posted about modifying the tune - even if you have an APU1 I think you still need to modify the PCM to accept a ZIF socket which allows you to burn chips and also do realtime emulation. In terms of a start Bin you'll need to find a stock bin (maybe from the Moates site) and go from there. Hope this helps

I'm glad Irene wasnt as bad as predicted - good luck to those without power!
Its the final few days for the end of our sales quarter, going to be noisy at work until Midnight Wednesday. I'll get to lay low Thursday/Friday so I can finally get the car together - hopefully fire her up on the weekend. Biggest challenge is supercharger pipework - the YSi is bigger that the S and T trims, and as a result the orientation isnt ideal. Spent a few hours playing with various shape 3" pipe trying to get the best compromise between a direct path to the TB without hitting hood / pulleys etc. I'll post pics when I get the first version hooked up. I'll probably do something more permanent and good looking over the winter - there is a local guy who fabs custom intakes for the drift/turbo/import community - he'll get version '2' done for me. Version 3 next year may be to switch sides, which will mean the AC and Power steering run off the passenger side of the engine... Anyway - back into sales mode. Have a good week!
