Gonna be using Z69 patch for the IM LC1. IM sent me a bad one and it took 3 weeks to get a replacement.... I have the VE tables very close to 128 across the board. What I need to tune is PE and AE. I want some ballpark figures/AFR's to tune for in theses areas. I was thinking for WOT around 12.7 across the board from 0-6400rpm. Or should I run it richer off the line and lean it out slghtly? Also what is everyone targeting for AE AFR's? My car seems like it lacks a bit of torque off the line...tires barely break loose. I just need a place to start and go from there. Another thing what are you guys seeing as an AFR at idle with a cam around 224/230 .580/.590 lift 112lsa?? See engine specs in sig...
Thanks

 

I can't directly answer your question (I have a DIY WBO2 but have never hooked up my dataq 194 to get fast enough sampling to catch transients for AE).

With that being said, (and has been said many times in the forums), tune for what the engine wants. I converted my 91 Z28 from auto to T56, and from stock TPI to AS&M siamese runner with an accel lower. The combined effect resulted in my AE/tip in throttle response being bad. It's not too difficult to tune based on how the car responds. For example if it's dead the instant you get on the gas, it probably needs a bit more fuel "up front" (there are a few AE multiplier tables that can help with this) and if it pulls for a split sec then lays down, AE Duration could be wrong (AE decay factor is too high).

The WB can help too, help you catch any lean transients or things like that, but each engine is going to respond different as far as how rich of an AFR it measures at the point where it responds best.
