2012 ECU swap for a 2010??????

Post by Jeep2011 »

I have been talikng to one of your CMR dealers here in new york trying to figure out what to do with my 2012 Jeep Grand Cherokee Hemi. He's at a loss as well. He wanted me to post the question if anyone has ever tried swapping a 2012 ECU for a 2010? Would this even work? I'm dying to buy a twin screw supercharger. Current mods include K & N CAI and Corsa cat back......please help!!!!!

Have you spoken to AJ at Westbury Jeep? If anybody can help you, its him and Arrington.

I saw Arrington's web page......11k is a bit steep. But I guess that's what happens when nothing is out yet. You can pretty much ask for whatever price you want. What a shame!!!! Does AJ from Westbury flash tune or just swaps out ECU's?

AJ tunes with CMR, so unless you do a swap, he won't be able to help you.

I guess thats what i'm asking......can u swap a 2012 for a 2010?????? Arrington claims that they use a NGC4 module and a wiring harness form a 2010 to solve the encryption problem.

B&G can do it. They did it for a friend of mine for his 2011 Hemi Express who is now running a 2010 ECU with no issues or codes aat all. He is a user on here "fasthemiram11"

I spoke to B&G a while back.......having some doubts sending PCM to get flashed!!!!! Also spoke to whipple and was informed that they will be coming out with a twin screw setup mid summer complete with PCM programmer somewhere in the 6-7k range. I honeslty can't wait......I'm shooting for somewhere between 500-550 to the wheels. Finally!!!!!

Interesting. I wonder who they're getting the tuner from? Or if they're talking out their asses, which would be pretty common for Whipple's staff.

I guess we will find out soon enough.......either way 6-7k versus 11k for arrington is a big difference especially when all they are doing is using a 2010 ECM. I'm guessing whipple will be doing the same
