M30 AFM+19lbs= WOW!

[Mystikal]

Look, I won't argue that point that MAF > afm. Not much point in that. BUT, unelss you've seen that the afm tuned with a safc is not effective firsthand proven with poor dyno results to back it up, then it's yet again, just more supposition on your part.

I'll bite.

Every car with an AFM sees excellent results on the dyno when an MAF/HFM/MAP is retrofitted. Yes, some of this is due to proper tuning, but it's a very simple fact: the newer sensor is much more efficient, especially during quick throttle transitions.

Word to the wise, MarkD is working on a chip that will allow an MAF to be run on an M20. Bobby, with that chip and your AFPR, you'll probably be able to dial in a good setup. I'd say go now with just the parts you have and get a baseline, and see if you're interested in the MAF setup when the chip releases.

Yeah, I'm already thinking about a MAF. Dyno will be done on March 3rd in Baton Rouge. I can't wait.

I had to re-seat my injectors today, there were a couple leaks at the base, but I fixed that right up today with a bit more cleaning. Also replaced my valve cover gasket as there were some minor leaks around the vc.

I picked up a few of the pieces needed to install the AFPR, but there are a couple parts I don't have yet and honestly, not sure where I'm going to find the one part.

The last thing will be a clutch BEFORE dyno day, so I've got my work cut out for me. I love this stuff:D

Any idea of when this chip might be ready? I was planning on going with his chip designed for #17 or 19 lb. injectors, but I might just hold off until this new chip hits the market.

I have stock M50 injectors (17.5#) ? I think. Would these be good for the swap or would I want to get the 19#'s ?

[AdironRider]

Ive heard the m50 injectors match up quite well.

stick to the 17.5#. 19# work but they're a little bit too much for a stock M20.

Hey guys,

I just put in 17.5 lb injectors and an M30 AFM and I'm suddenly getting a whole lot of pinging around 3k RPM... what exactly am I doing wrong? Is an AFPR an absolute must? Cuz I got one on the way.

Yes, and dyno tuning as well.

[hamann318is]

This is why I own a 318is. M42 owners don't have the same rights has human beings. We suck.

open the AFM mark the position of the little notches and increase the tension to richen it up and see if it goes away....remeber to mark it so you can put it back later if you need.

Get the AFR tested is the absolute best way but my other suggestion is a poor mans solution.

[MrK]

Alrighty then, I'll put in the M30 AFM again and try what you said, and I'm also expecting an Autometer AFR gauge in the mail as well, that should fix things up a bit. Thx for the info.

[MrK]

Yes, and dyno tuning as well.

I'm gonna have to skip dyno tuning, since there doesn't seem to be a dyno within 3000 miles or so of where I live (3rd world countries suck I know).

Narrow band AF gauges are pretty much useless.

[MrK]

My mech has a wideband, which I'll use to do the initial settings. The narrowband onboard gauge will be for fine-tuning under certain rpms/loads (during driving). That's ok, no? (Remember I live in a 3rd world country= no dynos)
