Post up your config of the Gen2

You do have it setup up for the TT chip correct? That being said you don't have all the functions of the GEN2 with out a Extender G chip.

I went by the set-up on the TT chip and the extender chip. The TT chip I can drive the car to what u see. Extender chip the car falls on it's face to almost dying every time in drive.

MAF out : gn stock MAF
MAF in: 4" magamaf
6 cylinder

Load source: use MAF/rpm
V-out 1 mode: spark control
V-out 2: set point

What exact MAF sensor do you have? Also, what version shows on the Gen II when you power it up?

 

[buickgeoff]

I have the maga 4" with built in MAF sensor. I just sent the gen2 into full throttle and they put version 1.19

I'm assuming when you changed to the Extender chip, you also changed MAF out value?

 

[TurboBob]

the chip for the Gen-2 is an "Extreme G" so MAF out needs to be set to Extreme/Pro

Even with a TT chip?

TT chip would be stock maf out.

Not that TT chips aren't good but to utilize the Gen2 you would need a extreme G chip.

The 4" mega is a s.o.b.

You can try to tune it in by adding fuel to get your BLM's down closer to 128. Since many of the BLM cells are high, you might add fuel to the mainscale setting in the Gen II. Add like 15% and drive around a bit to see what the BLM's do, and how it runs.

If it still has problems, then I would put an LS1 MAF on there and see if that fixes it up.

One other thing, double check the part# on your injectors to make sure they are 42's.

Well I'll put in the extreme chip tomorrow and drive it. Then post another file.

I checked the injectors. Their 42s. I would hate to change the from the maga 4 pipe. With ur guys help I would like to see if we can get it tuned in.

The Extender Extreme G chip will allow access to more functions on the Gen2.
I'd Get rid of that 4" Mega MAF pipe & install a 3 1/2" LS-1 or Z-06(85mm) MAF ...........you will be much happier!
Tuning with the 4" Mega with integrated sensor has been known to be difficult if not problematic.

Well I would like to keep the 4" pipe so has anyone ever put a block off plate over the inter grated sensor hole and put a 3 1/2 LS-1 or Z-06(85mm) MAF before the pipe? The air filter is a 3 1/2 so it could work before the pipe.

Yes I have made a block off and used a 85mm maf. Had to trim the pipe down a little to make enough room for couplings, maf and filter.

Awesome. Well my filter is in the fender well so I'll have some room in there. What year and type of MAF do u guys suggest? Z06, LS1?

[TurboBuRick]

85mm maf would be the closest to the size of the pipe.

Can u take a couple of pics of ur setup for me to get a rough guess on how to do this? Can I also get an 85 mm from like o' Reilly's?

Unfortunately that car is long gone.

Looks like o'Reilly has them. http://www.oreillyauto.com/site/c/search.oap?keyword=25318411
