diablo is the handcontroller and cmr is the tuning software that sends a custom program to the handcontroller

I'm now going on 12,000 miles with my GSM kit. I drive my car 40 miles every day. The supercharger was installed at the 400 mile mark. After about 4,000 miles, I removed the R4 controller, disconnected the auxilary injectors, added the SMT6 controller along with colder plugs and 39lbs injectors. It was a good set up prior to the Diablo coming out. Now that the Diablo is out, my car's currently at Injected Engineering getting a boost-a-pump installed, along with 55lb injectors, 2-bar map sensor and a custom tune with the Diablo. I have had no issues with my GSM kit other than a slight leak coming from the oil return line (just had to reseal it). Unfortunately because GSM had the first kits for our cars, and it was at a time period when only piggy-back systems were available, some things did go very wrong. No doubt all of the other vendors learned from others mistakes.

CMR Tuning - Professional tune done by an experienced tuner (via the cars computer), usually with the aid of a dyno. Once completed, this tune can be loaded into the car directly OR the Diablosport Predator which is a handheld tuner that anyone can buy and make little tweaks to their tune.

Diablosport Predator - A handheld tuner that comes pre-loaded with a couple of performance tunes. These tunes were achieved by a professional tuner using CMR software.

A person who installs any kind of power adder should get a custom tune (via CMR) that can be tailored way beyond the capabilities of the Diablosport handheld tuner.

I HIGHLY doubt that this will be happening with the new CMR tuning. You guys really need to know the difference between the two to make an educated decision....or comment on the matter.

Well first of all that just happend and the car was not very old...almost brand new. Two, if they still use anything like the "aux injector" it will still fail as the intake is designed to be dry and not wet. So under normal city driving the front two cyl just burn up from lack of fuel. The ONLY way to do this is the way the DynoSteve is doing it..and no I don't know him, but that setup is designed to work correctly from the start. A different tune is NOT the answer to that design..I beleive GSM has also changed to larger injectors. But thanks for your input

The new kits do not use auxiliary injectors. The fuel is via larger injectors only. The fuel tables are adjusted using the CMR software. While there have been some engine failures using the original design, there are literally thousands of cars running the original kits without a hitch. The next generation of supercharger is the I-Charger. With it's amazing efficiency and unique, compact design and linear power curve, it is really amazing to drive!!!

I feel it was the lack of understanding of the intake design that caused so many issues. Let's face it, NO ONE can say it was easy to tune these cars prior to Diablo and their software..But like all new cars, time always fixes the issues.

And I'll bet most of those were either 1. pre-tuning or 2. user adjusting things after initial set up like increasing boost.

Now that GSM has the tuning, and they are damn good at that, the problems are all but gone from what I have tracked...but again, the operator must not go against what I call rules of engagement.

Think about how many GSM cars are out there with no problems vs. a few after tuning that are tearing up the roads? Just like any power adder you are always up against potential problems.

Do you mind posting the link here on the one you say just happened?

I think Scott and GSM is totally worth checking out if you are in the market to make your car a beast!

Here is the link, it's not what I say happened..it IS what happened. Look, if they guy is lookig to invest alot of money, he should get ALL the info he can.
I am not goingto bash any vendor, many have already done so to alot of the early adopters, but I will say that the "aux injector" design was not a good one... and leave it at that

GSM has abandoned the auxillary injector design and is now tuning it the same way DynoSteve is tuning.
