I'm working with Greg from Blower Works, who, BTW is absolutely amazing. He knows these C4s inside out. He actually made a tester, I have to get a pic of it, that he has in his shop to test the chips. It's a 90-91 setup, just my luck.

Anyway, I have it on good authority he's a phenomenal tuner.

Anyway, he would like to see a fuel pressure gauge in the car. So I figure, I'll put in a trans temp gauge too.

I was thinking about one of those A piller mounts, I really don't like them, but can't think of a neater install. He's going to teach me the ropes of tuning as he does mine, and suggests that the FP guage is a requirement.

Comments, suggestions?

Oh, almost forgot. What is Greg's contact information and how much does it cost for him to send you a tune? I'm thinking really hard about adding some 36 lb injectors and will need a good tune.

Called an ECM bench. Used to test calibrations in house before playing with the car. Helpful to figure out why code does things when certain inputs hit thresholds. Thats how we discovered things like the MAX ve issues with $8D on injector pw.

My fuel pressure gauge is in my engine bay. The only reason I'd ever need to see it is if I suspected an injector or fuel pump fault. I set my fuel pressure to 50psi at baro. I expect a 1:1 rise with boost. You are N/A.. I'd set your fuel pressure to be about the same but you have a few other issues to combat.

1) Injector size
2) Max VE

$8D shows BPW in the datalog, not final injector PW. My code is patched to display actual final PW, so I'll dial my idle in to get the injectors to fire a reasonable PW so I can get away with higher fuel pressure (for better atomization). Plus, I can run a smaller injector which is really my main goal.

I also have code mods to my bin that runs open loop until 1400RPM, and I've altered my 02 swing points for open-tps closed loop operation so the corrections are closer to my desired AFR.

Your combo I imagine is harder to tune than mine..

It's about three feet by two feet, and has all kinds of knobs, displays, and dials. On the other side of the shop he has fuel pumps and all kinds of plumbing. I have to get pictures when I go back tomorrow. According to him he "invented" the PW hack and is pretty protective of his methods. I have to sign a non disclosure that I won't let anyone else read his chip.

He's offered to give me lessons on tuning until I get it. He says having the gauge in the car will make it a lot easier. I will take him up on it, should be fun.

hi guys,
sorry for butting in on your thread but i was
just wandering how much are the electrical fuel preasure guages ??
and where and what brand is the cheapest to buy ??
iv seen them sell for around $ 200,thats alot of money.
any ideas guys please ??
cheers

Can you run a FP gauge in the car? I thought for that you actually had to have a line coming off the schrader valve? At least that's how I test the FP in my car. Most guys say tape it to the windshield while driving to see it. Obviously that is not a permanent solution, but I don't know if you can do it otherwise. Is there some kind of gauge that has a remote sending unit (like two gauges) to safely run it into the car?

have you checked with www.summitracing.com? I am sure they would export.

guys who have these...how's the fit and finish in real life. I have searched high and low for a full pillar, but none seems to exist, these over lays seem to be the only option.

Stick 'em up there on the dash like we did in the old days. Or you can get them little chrome surrounds that screw under the dash!!!

I remember those.....problem is there's no dash to screw them under anymore.
