Yeah.. I just wish the DIABLOSPORT CREW would do the proper research before saying a certain vehicle is not supported. They were quick to ommit support for the LH6 "M" engine saying that it uses a different PCM than any of the other trucks. Which is NOT TRUE. It uses the same E38 PCM as all the ...

Mike / Johan,

Doesn't product support / engineering realize that the "M" engines use the SAME E38 PCM as all the regular trucks that you support????

The following Vehicles all use the SAME ECM:

E38 ECM Service # 12597121

V8 Cars
06-07 Chevy Corvette 6.0L
06-07 Chevy Corvette Z06 7.0L
06-07 Holden Commodore 6.0L
08 Chevy Corvette 6.2L
08 Chevy Corvette Z06 7.0L

V6 Cars

07 Chevy Malibu 3.5L, 3.9L

No, never got the Diablo to work. I sent it back and gave my money to SuperChips and am VERY HAPPY with it. When I talked to Superchips on the phone about Diablosport not wanting to support the "M" engine, they started laughing, saying it was a SIMPLE process in order to support that engine with ...

By leaning out the fuel mixture at WOT. GM sets their vehicles at an extremely rich AFR. Usually around 11:1, and lowering it to 12.8:1 can give you some impressive gains.

As an example, my 383 stroker in my Impala was at 11.5:1 when I first hooked up my wideband on a dyno. It made 330 rear wheel ...

The STANDARD engine for the Crew cabs is the Aluminum LH6 engine. It's been around since 2 0 0 5 model year. Nothing new and fancy to program for. I contacted SuperChips, and there 2815 DOES SUPPORT the LH6 "M" code engine on the NEW BODY STYLE trucks. It looks like Diablosport is going to miss out ...

ARG!!

The PCM was re-flashed three weeks ago to try and help my mileage and fix some battery drain service bulletin. Pulled fuse #47 / ONSTAR. Verified ONSTAR wouldn't work, then proceeded with the attempted flash. Vehicle was just parked in the driveway 10 minutes before attempting flash, so the battery ...

I'm sorry, but you are incorrect.

U7194 is for the NBS vehicles. U7192 is for the CLASSIC.

I both Emailed and called Diablosport and was told the U7194 would work on my truck. They don't update their website as much as we think. If you follow the threads on this forum, you will see plenty of other ...

Just purchased a new Predator. Build date 04-05-07 and it will NOT program my new truck. Unit came with Version V8r05. Even reflashed unit to make sure everything was OK... Flash date is now 03/22/07 - 1206 Attempted to read factory program, but it aborts at 100% with a Flash error of 0x40000. Sent ...

SnideBJ,

Have you noticed any MPG increases with the tune? I have a U7194 on order and will be getting it soon. I was thinking of loading the 91 octane tune, but then lowering the WOT spark advance from 4k-6k, and then running 87 octane. I'd then monitor the spark retard feature to see if I was ...

I would like to see the option to adjust sensitivity to the Displacement on Demand for these newer 2007 vehicles.

Also, I'd like to see PART THROTTLE adjustability to timing. That would greatly increase our ability to squeeze even more mileage out of these vehicles. Currently I only see WOT ...

This is for my 2007 Silverado with 5.3L.

I don't want to disable the DOD.. I want to be able to adjust it so that it actually works. My truck is rated at 16 city, 20 highway... I'm getting 15.9 hand calculated on the highway. I'd hate to see what it gets in city driving alone. Right now the DOD ...
