I always had to pull fuel in the High load page starting at 3K...all the way to 6K. Like a bell curve peaking at 4500....lo and mid I could pretty much leave alone...if anything richening in the lower rpms...
Take with a grain of salt, as you turbos are different....I have aTD04-16G set up...no HL wheels (yet)...

Thanks that should help for a base tune I haven't used any fuel control before so we will see how it goes installed the 560's, and dejon blowthru today. Tomorrow I am going to pressure test, & install the maft gen II with the lc1.

What are you using to pressure test?

Rob's pressure testing plate. Ive got a big air leak under the intake plenum not sure where it is coming from specifically

On a side not does anyone know which wires I need to tap into the stock maf wiring. fullthrottle sent me the wrong adapter for a 2g I think, and im not sure which wires to tap that 3 wire connector into my stock wiring. thanks

The 2g should work for you. It connects the stock MAS connector to the adapter and the GM MAF to the adapter.. that is what I am using.


As far as the pressure testing, are you still using the stock pre-turbo runners and intake bubble?

Should be this one:

That adapter there is a for a 1g DSM I believe. The 3s specific one is the 2G dsm/3s maf adapter.

I have the adapter sitting at home I can take a look.

Ah it was my fault then I saw 1g and thought it was for my 1g 3000gt :S. Since I have installed the larger injectors, and ls6 maf/maft gen II. The car has been running horrendously It stalls when I am at a stop. Is idleing all crazy, and is jerky with no power.

I used -35 for mainscale with the 560's, and I put in 6cyl, 3000gt 2g for maf, and lc1 for wideband left everything else the way it was. I think that the vacume leak I have might be causing this. It sounds like it is coming from under the intake manifold but I cant pinpoint it. I changed the lower intake gaskets yesterday because I thought it was them but still the same. Any ideas

Have you pressure testing for leaks? If so you can try and squirt some soapy water around the lower injector seals. Also I know you do have to tune out the vac leak for the PCV system because of the blow through. You

I have a 94 stealth sohc. I built a custom turbo kit, 450cc injectors, I had it running on a afc neo, but i am switching to the MAFT gen II. I hooked up a adapter wire(off ebay ) to gm maf sensor. I hooked up all wires the same as it says for the turbo stealth, (just like i did for the neo and it worked fine)and I cant get it to do anything. All it does is idle crappy and run super rich on my AEM uego wideband. I have the mainscale set at -52 and move it up and down and nothing happens. Also the rpm isnt working on the gen II, I was thinking that maybe that has something to do with it. Anyone?

I was also thinking that the adapter wire I bought might have the wires in the wrong position on the plug. Anyone have a pic or wireing diagram for the adapter wire and plug? Thanks

Well I switched back to the stock maf, and I got it to run just like I did with the afc, but I cant get the rpm to work on the gen II. With the afc neo i finally figured it out thanks to a 3si memeber, but It isnt working on the gen II. Could something have burned up?
