Hello all,
I just completed swapping a 6.4 Hemi into a 2008 Wrangler, it's up and running but in dire need of tuning. I am pretty good with the hands on stuff but this type of tuning is all new to me so I am looking for a little direction before I make any changes. I purchased the MPV2 with the wideband option but I haven't installed the wideband yet, I am looking to improve the drivability for now, any advice would be appreciated. Here is what I'm working with.
2008 Wrangler Rubicon
2106 6.4 Hemi from a SRT Challenger
G238 6 speed manual transmission
35x12.5 tires
Computer and harness from Hotwire.com I believe the computer is from a 2010 Ram truck
The main issues are throttle hang and it seems to shut down on hard acceleration if I ease into it it's okay.
I did find a tune file for a stock 2016 6.4/6 speed Challenger and compared to what I have and it's different in almost every way, I have heard not to make to many changes at once so just wondering where to start. I have attached the tune that Hotwire provided. Thanks.
Gary
