Interesting MAF conversion

[Erick]

Maybe something to consider if you happen to find a MAF with plug laying around. Otherwise really not worth the headache for the gains.

It's still a good upgrade just a bit outdated. A generic MAF and an analog signal conditioner was Split Seconds claim to fame back in the 90's, they sold a bunch of units but there were a bunch of complaints about how it never really worked perfectly. They later moved to a laptop programmable unit and STILL had issues. That's why on my M3, I just went with Alpha N and it's worked flawlessly the 6+ years I've had it. MS is awesome, but I just don't like losing the OBC functions. Gotta work on that.

but if you guys want to keep pursuing a MAF conversion as if it were the holy grail of a magic 20whp and throttle response from a stock M20, don't let me stop you.

Technically just adding the MAF doesn't really add anything more than maybe 1hp. I have no interest in hp gains, with 280k on my DD all I care about is getting better airflow to the engine, I'm not interested in power atm.

I just so happen to have an extra MAF and plug in the garage so that part costs me nothing. All I would need is the means to tune the engine.

That's not exactly a minor detail...

already done; Hoveringuy (the M54 swap guy) makes an little adapter that converts the PW signal from your injectors into the same signal the OBC and MPG gauge need to work.

I had a F360 maf with a SMT-6 on my 318is for a while. I went back to stock after I realized there were no advantages.

I realize that, I'm looking into Miller's WAR Chip vs MS at the moment. I don't expect it to be cheap at all. I was curious to see what/how the guys software worked as an alternative to the two because I'm planning on building a Stroker engine for a swap mid-late next year. I would like to have software in place that will allow me to do small things like an MAF right now just to improve the overall drive of the car and still allow for the comprehensive tuning that will be needed for the Stroker. I'm not a huge fan of MS's GUI.

MS doesn't need a maf sensor, so if you are serious about it you might want to do more research in that direction.

there is lots of different software you can use for tuning, including megatunix, megatune, tunerstudio, megalogviewer, etc. There is no official MS "gui", unless you're just thinking of megatune, which I agree is quite outdated. Thankfully we have tunerstudio now. :)

I know MS doesn't need an MAF, I'm just starting my research on tuning. I'm planning on a FI & ITB setup so I will be deleting the AFM/MAF altogether when I do the swap. I was probably thinking of megatune as the "gui". I'm drawn to the Miller chip mostly because of it's "plug and play" quality. If it can give me the same type of tuning capabilities as MS then that would seem to be a simpler route to cut down on time necessary for building and wiring the MS system. Although because of the nature of the components in the swap I don't know if a programmable chip with the 173 ecu will actually be capable of achieving an accurate tune. luckily I'm not going to even start buying parts for 6 months so I have plenty of time to research.

hardware wise, it's sort of a toss up between MS2 and Motronic 1.3. They both only have 2 injector drivers, although you can have up to 4 now with the new code. MS2 supports up to 6 ignition drivers (3 is plenty) and true acceleration enrichment which is something Motronic will never match. The advantage to Motronic is all your things like idle and warmup are already tuned.

check out the Motronic adapter board on diyautotune.com.. no wiring needed. ;)

The only reason I would go to a MAF by Miller is if in fact all 3 of my m30 afm's took a dump. It seems like it would be more reliable.

I would really like to be able to plug and tune my motronic ecu... I like the idea of keeping it stock and having all my obc and guages work. oh, and look stock
