Im currently embarking on custom turboing my M3 (what other way is there in the UK!)
After looking into the standalone options, I have narrowed it down to 2..
The AEM standalone (using my own a custom loom), or an Autronic SM4
Does anyone have a preference on these please?
Also, can u explain some more about the bigstuff3 plse topshotta? I have heard the brand name b4 but assumed it was a drag car focused ecu?
is it possible to start a poll on here also?
I want to start a 'which standalone is best for BMW turboing" poll to see what others favour
