SCT or Diablosport Tuner
I am looking for a handheld turner that is not too expensive to tune my 2015 Corvette Z51. Just wondering if anyone has used an SCT or Diablosport, and which one would you use?

I don't have a ton of experience with it, but I did buy the Diablo Sport inTune i3 Tuner mainly to disable the AFM permanently. The tune they provide (and require) for that option to be disabled has more pep and quicker throttle response in my opinion.

Thanks stevettecc7
That's actually what I want a handheld one. But I am confused about which one to get. I read about HP Tuner, but you need some experience to use it. I readed mixed reviews about DiabloSport and very little on SCP. I was hoping I get some user experience with SCP.

I can't speak for the Diablo canned tunes. It was easy to use and I got it from Diablew who added his own flavor to the programs. Takes out AFM, increases throttle tip in and changes the transmission shifting.

Copied the email
I change a lot of things... a small sample of just some of the things are: disable engine torque management, adjust part-throttle fueling/timing, WOT fueling/timing, knock retard settings, throttle settings, tranny shifting settings (pressure/firmness, shift points, quickness), etc...

The concern I have with these handheld devices is if I do screw up. I know the units keep a stock backup. Has anyone seen or heard if the backup got corrupted? Is there a backup to the backup or can you create a copy of the backup? I don't want to add the tune to the car and drive it a little and then I start to get CEL.

I also used it to tweak the engine fan parms which helps it run cooler with a lower thermostat, bigger fan and larger radiator.Their tech support is excellent.

More interesting is the ability to increase the tip in so you don't have to buy things that fool the ECM into giving it more throttle.

I can definitely get you hooked up with a correct version Diablosport inTune or Trinity programmer and a custom tune for your car... I've done a thousand of those over the years...
With the custom tune, you'll gain even better/quicker throttle response & acceleration, stronger/harder pull, smoother & quicker power delivery throughout the rpm's, better automatic tranny performance/shifting, etc...
I change a lot of things... a small sample of just some of the things are: disable the DOD/AFM, disable engine torque management, adjust part-throttle fueling/timing, WOT fueling/timing, knock retard settings, throttle settings, automatic tranny shifting settings (pressure/firmness, shift points, quickness), etc...
