MSS54HP E46 M3 - Single Bank 02 Control
Posted: Mon Jul 20, 2020 2:53 pm
Hi, I've currently got a turbo E46 M3 turbo running E85, tuned using an AEM v1 in a semi-piggy back installation (HPF). I do all my own tuning etc.. I converted the original tune from gas to e85 etc.
Now I'm looking to convert to an OEM DME/MAF (aftermarket) setup. So far it seems that your software/tuning platform will work great for my needs.
That said, It seems that I'll have to overcome the dual to single bank o2 control issue. I was considering purchasing a copy of IDA Pro and going down that path but figured I'd ask if you have any advice?
As an alternative I did think of a hardware solution using some custom signal circuitry, microcontroller logic, and a wideband to feed the DME what it needs (narrow band signal, with appropriate timing to ensure one bank doesn't drift and the LTFT and STFT are equal across banks) to more or less end up with single bank control.
Any thoughts would be greatly appreciated!
