#Diablosport tuner cable code#

You can read a CEL code with a code reader but can not clear it unless you have the official Dodge Code Reader Unit which God only knows how much that costs even if they would sell it to you.

It is called a level 1 and 2 system designed to prevent hacking into the car. there is a completely new security code system that Dodge installed in the 2018 vehicles. Maybe a tuner for the 392 never makes it for sale. Will Diablo sell an unlocked PCM for the 392 like they do for the 5.7L, I have no idea and we will have to wait and see what develops. If it is a way to do a tune and be able to go back to stock by replacing the PCM on the 5.7L it should be the same for when they sell a unit for the 392/ I asked this on the 5.7L as maybe someone has a 2018 R/T 5.7 that has bought an unlocked PCM and could answer if that is the work around for tuning the car. So if one were to purchase an unlocked PCM with a custom tune and removed the stock PCM and ran the car for a while, if you needed to take the car in for service and put the stock PCM back in after removing the unlocked second PCM that has the tune, would the Dealer not be able to tell you had been using a tune. I noticed that Diablo says they will sell an unlocked PCM if you do not want to send your PCM to them to have it unlocked. I traded that in three weeks ago for my current 2018 R/T Scat Pack 392. I had a Trinity on my last car which was a 5.7L 2013 AWD R/T. They do not yet have one for the 392 (6.4 L) engine but in a post on their forum dated July 30,218 it said they are close to finalizing the product.

I would like to have comments on this question from people that know the program or have installed a tuner on their 2018 R/T 5.7 l car.įrom what I can see on the Diablosport site, and I may be wrong, Diablo only has a tuner for the 2018 5.7l and 6.1L. Maybe Diablosport will come up with something clever that will allow you to put the car back to the stock software and not leave a trail of crumbs indicating that you had modified the programming. However if buying the unlocked PCM will not keep the dealership from knowing that you had been up to something even when you put the original PCM back into the car then I will have to wait for the car to essentially be out of warranty before I would go for a Diablosport Tuner. If the work around will be to buy an unlocked PCM for the 2018 Scat Pack 392 and that will keep one out of trouble with the Dealership Service Dept. I think if you purchased an unlocked PCM and swapped it out for your Performance Tuning then you could put your original PCM back in the car if you were taking the car in for service and they would not be able to tell what you had been doing. So if you went the having your PCM unlocked that would be a major red flag for the Dealer. If I am correct, I see that if you have a 2018 R/T 5.7 L and by the tuner from Diablo Sport that you need to either send in your PCM to be unlocked or you have to buy an unlocked PCM from them. I know on my 2013 when you put it back to stock you could not tell that anything had been done or changed as it was back like when you bought the car. We were talking about when a tuner becomes available for the 2018 Scat Pack 392 should I get one like I got the Trinity for my 2013 R/T? He was telling me that if I did a flash of the PCM in the car with a performance tune, even if I put the PCM back to stock before going to the Dealer for some service, that the Dealer can still tell that the car's software had been modified. I was speaking with my son in law who is a computer tech the other day.
