It was fine before but since I played with the min fuel trim table it refuses to pull more than 9.9% and throws a MIL.
No matter what I set it to from 0% to -25.6% it flatlines at -9.9
It's getting very annoying cause every time I back out of the gas it pegs -9.9% and throws the MIL even though while all other driving they stay within normal percentages.

 

not sure what you are trying to accomplish but you want your long term fuel trims to be less then or equal to +- 3%.

 

Not even worried about LT trims.
Just trying to make the negative regain the ability to pull 25%
The setting is doing nothing.

 

Post your rom.

 

Rom is 96530706
Tephra v7 maf

 

I switched to an unmolested copy of the rom and pasted my maps and settings.
We'll see if that works.

 

I literally meant post your rom lol :')

 

New rom
Retuned fuel map to get trims around 3%
Only pasted injector scaling and latency from old tune.
Still throws p0125 insufficient coolant temp for closed loop operation
Any idea why it would throw that code after 30 seconds of the car actually running perfect with trims on point?
