Subject: Re: accel enrich delta tps, for a 58mm Tb. how to tune? '91. anyone have a .bin for their car that is ab by djxib on 2011/9/19 18:24:23 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 |
