Hey fellow FI peeps just wondering if anyone knew of a performance AFM upgrade for the 280. I took my 280 to get its brakes checked and my mechanic saw my pressure regulator and said that i should also get a performance AFM unit cuz it will really boost the power on these things... he used to own one so i guess he knows. Im gonna ask him more in depth about it next time i go in but i was just wondering if any of you guys knew of one thanks.

I am converting to a manifold pressure sensor to get rid of the restrictions caused by the AFM!

How does that work? What is it? ...

will if i knew what that was or how to do it buddy id be doing the same my afm is all screwed up anyway and i finally found out how to fix it today so thats gonna be my next project tuning it for max power til i find an alternative... you makin your own custom sensor setup or is there one already for the z that one could purchase and install?

I will map the whole thing out when I get it working!

It is going to be on the '72(83 turbo engine).

Would that be a mass air flow sensor? I've heard of it being done. It would require more sophisticated engine managment that the early Z has. Let us know if you get it working.

A mas air sensor generally uses some form a resistance measure of a heated wire, I am going to use a map (manifold absolute pressure) sensor with GM engine management-and It isn't too far from working right, now! I will outline the whole thing in a technical article when it is proven in the car. It is just getting to the tune it, tune it, and tune it soime more stage-while sitting (roughed in-ugly spagetti accident looking mess) in a parts car. I hope to be spending more time on it in about 2-3 weeks-after the '72 has been undercoated (inside and out), and the bodywork is done.

well im stoked cuz i went searching last night and found that we can convert turbo AFM's (which are approxiamately 33% larger air flow) to work on lour car and its super easy so for now im going to do that this weekend and see what kinda of a difference it makes. but yes do tell of the MAP system once you get it running exquisite. Later all

Also the BMW 325i 1985-91 has the same Bosch fuel injection and a much larger AFM. It is larger than the Datsun turbo and is already set up with normally asparated electronics inside. It will need some minor adjustments though for the added displacement.

Wow... just stunned. I've been busy converting my Kjet (mechanical injection) 80 Volvo to EFI and prepping to turbo it, and tons of folks in the volvo scene are using megasquirt. It's a trip, I don't see much of anyone using it here.

It will get rid of the MAF, allows full tunability with a laptop. If you already have EFI, you're looking at maybe $200 plus the laptop if you don't have one. Look into it. I'm going to go that route with my 72, next spring maybe, time's running out for this year.

Well, Isn't that interesting! Thanks for sharing, I'll just have to spend some time checking it out, especially the Ultra version as it come available.

hello mr. zgod: listen... if u would.. can u please tell me how you found out how to fix your afm, mine is a little twacked i think as well, i believe the flap on the inside is now opening ????? thank you for any input?

I'm surprised nobody mentioned the 240SX AFM unit. It's got a bigger throat and you can get dadapters in clear plexiglass from Pallnet. It's a documented install.

thx
