LS2 Intake manifold and LS7 maf swap thread
#82
So the problem has been solved! This was not a wiring issue, this was an ECU incompatibility with the LS3 throttle body. Per this thread...http://www.hptuners.com/forum/showth...ced-code-P1516
Which details the issues people have been experiencing with Nick Williams 102mm throttle bodies which are built on the LS3 internals, HPT has developed a beta version with a patch that allows editing of the P2101 and P1516 parameters. They sent me a copy of the beta along with a patched version of my tune file which gave me the options.

What i found interesting was that it still triggered REP mode even if you deleted P2101 and P1516.

Finally got the MAF honeycomb in from treadstone today, and installed it in the new airraid maf tube, this is a resin maf tube, giving it a try to see if my IAT's are consistently lower, plus i also needed one that was slightly longer to extend into the CAI box as my filter is having some trouble clamping on to the spectre one.
Some of you may be asking why the maf honeycomb since its common that people remove these thinking that it adds horsepower. The maf honeycomb increases air velocity significantly, and also helps increase maf sensor accuracy.
after the epoxy dries ill go ahead and install this tomorrow.

I saw high IAT's before even with the stock plastic maf housing and silicone intake tube, honestly its just because of the bay getting really hot. One of the thing's ive noticed is the LS7 IAT does in fact react ALOT faster then the LS4. So the instant I blip the throttle, my IAT's will drop 20* and drop rapidly down to about 100*. I'm in the process of ordering various heat wraps now to try to improve insulation of the exhaust section under the intake tract. You think the MAF tube gets hot? Try touching the throttle body. I can't imagine that its good for the life of the throttle motor.

Do you not have your crossover wrapped? My crossover has sandwhiched aluminum foil underneath dei titanium wrap. I can put my hsnd on the tb after a 30 minute drive and not burn myself. Also stop messing with the dumb box go fender well and enjoy ambient iats

My crossover is wrapped, but its still not enough layers to keep the heat inside. I'm not putting my intake in my fender, ive already been down that road before with other cars.

How much did you have to enlarge that existing opening to get that big *** filter thru?
