          I was reading a bosch egine management book and it said that the voltage drops will the increase in engine load. do you know if the wire is heating to the correct temperature when key on and engine off?

            The MAF is working 100% like it should now, not sure what was up before. Still am loving the swap it completely transforms the engine

              good to hear its running well.

              I have been doing research to a m30 maf conversion. I have come arcoss a pot style TPS. Would make any difference on how the car runs? or would a normal tps will do? i thinking that the m30 will have a similar setup to the m20 if not the same.

              im looking at using the apexi safc - 2 with a lc-1, also looking at bying bigger injectors aswel at a later stage.

                the apexi requires a variable TPS, you can just use the e34/e32 automatic m30 tps, as it bolts right in. Ya doing the conversion on an m30 would be identical to an m20.

                  MarkD is coming out with a MAF kit soon, and it will be tuned properly.

                  Not much details yet, only that he's already done it to a 3.2L m20 and just needs to tune it for stock/lightly modded m20.

                    This is what I've been waiting for. Any word on how much longer until it comes out?

                      Im hoping this summer, but i guess it depends on how much time he has to spend on it and get it finished + start soucing MAFs and everything needed for the kit.

                        Perfect source for the plastic! you must of been there when he did it. i dont think i would ever notice they where trays.

                        does anyone remember the little toy welder that spun a plastic rod intill it got hot then "welded" the wheels and chassis on to the car, then you wrecked it and did it again?
                        that was actually a pretty good way to tack up or even put plastic back together.
                        anyways PROPS.
                        nice rework of the afm

                          where did you get that high flow filter/heat shield combo?
                          There is a certain elegance to the nasty old M20s that is hard to recapture in the more modern power-plants.

                                I believe it is still in development. I know he did the tuning for Metric Mechanic which includes the MAF swap with their engine.
