Thanks, I've been reading the dialing in the single thread and it seems that there is a solution that phila_dot made for the S4, but I still do have some concerns about the fueling issue between the banks that Snow Trooper has brought up later in the thread.
At this point, is the "hack" a better solution or is it just worth it to leave the ECU as it was designed/compiled and go with pre-turbine O2's in their specified banks?
The hack simplifies the setup since now you are able to run one sensor post turbo. I begged and begged for the hack mostly because I didnt want to add in the two sensors pre-turbo due to the shortened life span. I think either way will work just fine.
Even with a slight voltage offset, my trims went crazy. That was with the LC-1 feeding both banks inputs.
Either you run both sensors pre turbo, or one post turbo with the hack. One sensor post turbo without the hack, and your trims will be retarded. Your overall AFR can be spot on, but the ECU will almost always trim the two banks opposite directions, usually ending up in really shitty part throttle/cruise. Like stated before, the trims eventually will go +25, -25. At WOT I dont really know. I was under the impression that at WOT the trims were ignored, but later it was said that they are also used at WOT. Not sure, but even more reason for the hack for me.
I can only speak on my car, and what has worked for me thus far. The hack has helped me a ton, and I can never thank the guys that put in the work for me enough. I have been running the hack for a while now, and it has been nothing short of amazing for me.
