This is probably one of the 1st bad "features" if you will, of my specific car.

Well I resurrected this because my AFM went bad and I was thinking about going MAF-T anyways...just seeing if theres any more progress from anyone. I'll be running blow through, btw, since I have a venting type S.
Hrmm I figure this thread would be the best thread for my question so here goes- With my current set up I am hitting fuel cut right near the top of the RPM range. All I have is a K&N Cone, BIC DDP, and 60trim CT upgrade. I plan on getting a maf/t next week so I can get some basic tuning and tune out fuel cut. I should be able to tune out the fuel cut with the maf/t shouldn't I? It will be on a dyno of course with wideband 02.
Excellent, just like I hoped. And thats a very good writeup, that will likely be my bible next week when installing and tuning the thing

Great write up! I wish it was around when I did mine. Just make sure that those of you with the safc and other thigs that are soldered in you keave enough room for. I have my WB, SAFC & MAFT soldered into my harness and it is tight.
I'm pretty certain it doesn't matter. I've run it both ways, and it seems to make no difference at all.Allan_MA70 said:
Ok, I got mine and have it installed. I'm a little confused on how to tune the partial throttle part. I am measuring the Vf signal and it seems to jump around to much to get a fix on it. I have the base set to 2 like it says for 440's. and I get everyware from ~1v to ~2.2v to ~3.5v while going from light throttle to moderate to half throttle. Seems to hang around 3.5v then go to 2.2v with more pedal and sometimes 1v.
Any tips or suggestions, suggested settings to start at perhaps? I'd appreciate it. Thanks

It's still there, although the path has likely changed slightly, and a good portion of it was corrupted by a server crash I had a while back.
http://idriders.com/Supras/MAFT/manual.htm (bunch of corrupt junk at the top, but scroll down, it's still there...
Pictures (including the corrupt ones) are here: http://idriders.com/Supras/MAFT/manual_files/
I'd fix this, but I don't have the MAFT anymore, so new pictures are kind of a moot point.

Instead of reading the vf signal can I just read my wideband, or is this the voltage correction my ECU is making?
They tell you different things.
Use vf to tune low to mid range, where your ECU is still running in closed loop.
Use your wideband to tune WOT.

How many shops know how to tune with the maft? Is it a universal type thing, or specific program?
Edit: I am planning on using the maft ($199), not the maft pro

Not many - your best bet is to find a shop that specializes in the DSM cars - Mitsubishi Eclipse, Eagle Talon, Plymouth Laser. That where this idea originated from, and it's been available (and popular) for those vehicles for a lot longer. Just remember that they can't tune by knock on the Supra like they do on the DSMs.
That said, it's not rocket science, any shop that understands tuning should be able to deal with this device if they are willing to read the instructions.
