On a 2007 gt500, the ngauge has 3 spark pids. One of them is sparkm (measured spark) which reads a little over 2 deg higher than the other spark pids. Is sparkm the actual spark engine is seeing or...

Problem solved!! Had to disable the SIP sensor tests
Add some decel spark. Add up to 5 deg at 700 rpm and taper it less as rpms go up
I don't have a wrench light. Says Engine Failsafe Mode in the information display. Resets by turning car off then on. You can see the wheel torque error in the logs when I accelerate from a stop....

Here are two log files that have car going into failsafe engine mode and the tune file.
Its a 3.4 whipple not a 4.0. I mistated
Solved the oscilation problem with foam diffuser in ram air from hood. Still have failsafe issue and is worse with smaller blower pulleys. Made 997 whp at 24psi through the 4l80e auto yesterday.
Will do. Going on dyno tonight.
whipple 4 liter,5.8l sleeved motor, ported heads, jdm SS cams etc. Currently at 22psi. E85. Whipple 123 maf tube and jlt 127 will peg the maf.
No DTCs are shown after going into failsafe.
Car has a large whipple, monoblade built motor etc.. I have it tuned well other than the occasional engine failsafe mode when taking off from a stop with light to medium throttle since changing from...
First log is with 127mm maf tube. Second is with 148mm maf tube
I am new at this. Last year, my car was tuned well with a 127mm Maf housing. I built a new motor this year with cams, larger blower and a 148mm Maf housing. I have the car tuned extremely well as...
Last winter I had a shop put in a 4l80e in my 2007gt500. Since then even when using the same tune I had with the manual trans where long term fuel trims worked and it would complete the catalyst...
Thanks but the TPS threshold (max position to enable LTFT) is set at 59 percent in this tune. I would think that would be fine because majority of driving is below this. I checked the stock tune...
I cant get LTFTs to work. I think I have everything on and set correctly. Car is otherwise tuned perfectly on e85 at 18 psi of boost with a large monoblade and maf tube. Short terms don't correct...
