Yeah wow that is very strange. I usually gauge the amount of power it is making by watching the estimated air it using and looking at my air to fuel ratio to have an estimation of horsepower. It is making more power based on my analysis from 4000-6400 RPM with the more advanced timing.
Also, I would like to say that I plan to do a turbo build on this car shortly. I am going to start with the ls1 that is currently in the car and keep it at low boost until it either blows up or I get bored. I am already building a studded gen 4 lq4, lsa heads, a big turbo cam, and 1000cc injectors. I also have a stage 4 RPM t56 and will most likely have a 12 bolt or a 9" in the future. The thread will continue!!!
having looked through the thread i want to say thanks to everybody contributing. this forum is just great. i also wonder why op doesnt get ridd of the maf. has it been suggested? it would make life so much easier.
If you read further I did in fact get rid of the MAF. I had a devotion to try and keep it but the combination of a fast 102/ 102 combo and a big cam made that idea not take place. If you have any questions or want to look at the finalized tune let me know!
yeah, i dont know what that contraption is really for.
Hey guys,
So long story short, I live in michigan and I went to start my trans am (operating on speed density) and it was running weird which I assume is due to the varying IAT temperatures from when I tuned it. At the time, the temperature outside was 32F and I am currently using COS5 to allow for a IAT VE multiplier. Can someone determine if my A0014 table is accurate?
I also noticed that when I revved it a bit, my rpm hung a while and there was a lot of overshoot when the rpms were coming down (would go to 600 when idle is set at 900), anyone know what I can change to affect this? I had slight problems with my car during the summer with spark knock and then it had a harder time idling due to the varying spark advance.

It seems to me that A0014 should slope the other way... i.e. cold air is denser and has more mass per cylinder volume.
That is what I initially thought too but after I read all of the different threads online when I made the table values, everyone had it in opposite order. I am not sure why this is the case.
