What are the long term trims...?
What are the long term trims...?
Are fuel trims are pretty far from each other. ltft bank 1 -6 ltft bank 2 -28.
Also another problem we have is injector pulse around idle is 1.7 ms. Adding 25 percent to the injector flow does not pull the fuel required to get the fuel trims in check at idle.
fuck me.ctz here is my tune
No one ?
Sorry, I've been out for a few days...
the LTFT's diverging by a large amount across banks indicates a physical problem...
if LTFT2 is -28% then bank2 has something causing excess fuel (injectors sticking open...?)
Hacking the IFR table will not fix the problem, and if an injector is sticking open you will see no difference.
Is your FPR manifold-referenced...?
Your VE tables don't look correct/complete.
Are you using a wideband...? If so did you disable CL/LTFT/STFT/SOL (in B3647/B3649 stoich cells will do SOL/STFT trimming)...?
I am using the wideband on Dyno and a AEM uego. I got the fuel trims even know. The Map sensor was was not scaled right and was not reading 80kpa with engine off. But having issues on the dyno when we get under boost 10pd plus fuel trims keep trying to remove any fuel changes that I make!

Map sensor scaling was causing 1 bank to pull a ton of fuel but the other bank was not pulling an unreasonable amount?
Yes I still think thats weird also but now that I scaled the map sensor the sort term and long term seem fine. Now only under power is it trying to pull fuel when I try an add it.Originally Posted by picnic_george
Also when coming into boost I get real Rich for a min and it stumbles then it gets after it
Post new log file.
Is your FPR MAP-referenced or un-referenced...?
