antony 0 Report post Posted December 26, 2007 I've only skim read it, but from what I understand he has matched a 325i AFM (m20b25) to a MAF from a 328 (m52b28?). Looks to have given him some good results. linky He is using a tunable piggy back ECU, and I'm not sure how this would go with the stock ECU. Also interesting is this guys twin throttles (m20), he's added another throttle body onto the other side of the intake manifold . linky. Quote Share this post Link to post Share on other sites

antony 0 Report post Posted December 26, 2007 I've also found this. On the M30 AFM swap. Also has good write up on his mods here. Still umming and arring over doing this or individual throttle bodies. Quote Share this post Link to post Share on other sites
