Popeye775 16 Posted June 5, 2021 Hey all, So it has been a while since I have posted to this forum but I just had a basic question. Recently, I did a 2L ABA bottom end swap on my G60 (kept the 1.8 head on). Did a ton of upgraded parts (including injectors and things like that). Just for a preface to this question, I have an adjustable FPR (running 3.5 bar), the 30lb injectors, and a stage 3 BBM tune on the car with a 268 cam and 68mm pulley. My AFR reads 14.5-17 while idling, and while driving it averages 14.5-14.8. Cruising AFR looks great - I am pretty sure - but am unsure if the idling AFR is good or not. So I was just curious about that part. I have heard things about needing a stronger ignition coil (like a MSD blaster coil) for stronger spark. My dad actually had this issue with his turbo E30 and needing a stronger than stock ignition coil when his AFR was reading lean. Just wanted to see if this could also be the case here? Or if these AFR ranges for digifant are accurate? I have heard that digifant is pretty crappy when it comes to AFR so I just wanted a little help. Thanks all in advance Quote Share this post Link to post Share on other sites
