Diablosport Forums

Hi there,

I just recently got the diablosport trinity and PCM for my 2015 charger RT. I loaded the canned 91 octane tune and the only parameter I modified was the neutral/park rev limiter to +600. After the tune installed I started the car to find that it's surging really badly in idle. The RPM will spike up and down by about 500-800. I reset the modified parameters and installed the regular 91 tune and it was fine again. I repeated this process to make sure that nothing went wrong with the first time I wrote it and it happened again.

After searching the forums I have found that there are other cases of this happening where you guys said you were working on a fix. That was back in March and I'm wondering if there is any way to remedy this issue as of yet?

Thanks

I'm having this same issue. Seems to me that part of the tuner should let you set the rev limiter to +6,000, not +600. If I adjust these settings at all my car won't idle. I know there is no real need to adjust them, but I, personally, would like to remove this limiter.

its a bug that sets the rev limit to 0 rpm when you adjust that.
Setting that value to 6000 rpm and then free revving it will likely result in damage, there is a good reason that limiter is at 4K to start. Id advise not massing with it to be honest.

I have a 2014 Dodge Charger R/T and I am having the same issue. Mine is also modified and has a custom tune. I think the reason behind not being able to adjust it correctly has t do with the tune. What company or who tuned it? i had Arrington Performance a while back. hopefully this can get figured out because a 3in straight pipe on this car would sound amazing at 6k.
