What i do not understand is which front scaling to use.
There is the stock front scaling, the ots front scaling, the ztan front scaling and ecutek front scaling.. All different.
I use ecutek front scaling that is quite offset from the others and my 12.3 afr with that scaling, it s more like a 11.9 afr with ots front scaling
How do one choose the best one? And how do one do a correct scaling for a wideband aftermarket sensor?
