Oh man, not good to hear!
I don't really have any way of confirming what year mine is other than they told me it was a 2018. Are there any markings or numbers anywhere on it I can check? The engine/trans/t-case are all out of 1 unit at least.
I called Motech twice before buying it and they reassured me I could do it and they would help me with everything over the phone. He did suggest I go ahead and buy HPTuners.
What problems did you have with them?
I tried to avoid getting HP tuners, I didn’t want the expense just to turn off some lights - which is why Motech suggested it, but never told me what to do to turn off lights, and what lights to expect.
I used a remote tuner (guy) with an EFI live autocal. That didn’t work well, and most tuners will suggest to not mess with the Gen V engines in EFI live. So, had to get HP tuners anyway. I’m in just under $1,000 in tuning so far. Hopefully my tuner can get it setup right. About $175 of that was in licensing in EFI live, so you could easily avoid that. So far I have not licensed the Jeep computer to get into dash lights yet.
I suggest you power up the harness and read the computer at least to get the VIN. With the VIN you can figure out the year and with the year year you can make a plan.
Also look at the transmission computer. If it’s a t87 it’s pre 2017 and does not require a license credit. If it’s a t87a then it’s 2017+ and has to be sent to HP tuners to be unlocked and costs $200.
If the engine computer is 2016 or earlier it will require 2 credits ($100). If the engine computer is 2017+ it will require 4 HP tuners license credits ($200) license and is a more complex process to unlock. HP tuners will have to be connected to the internet and the computer the in order to unlock, but that’s just the first time.
My engine is a 2016 and wouldn’t make power. Motech said they have seen this problem before and sent me a file that is a 2015 operating system. That fixed it, but I also had to license that file for another $100. I don’t know if this is specific to 2016 or is a 2016+ issue.
These things add up quick. I didn’t plan to spend this much, and hopefully my learning curve can save someone some else money!
