I have a 2011 Jeep Wrangler with a 6.2 L86 motor (swap done by someone else).
I purchased the Jeep with the swap completed... with issues.
I took the Jeep to two different people to help with a tune. One did virtually nothing and the other was critical of the previous tune.
Then the L86 blew up. I found out the previous owner knew about the issues but did not disclose. Might have been a wrong cam or other improper parts.
I now have a new L86 (2017 motor) with complete DOD delete kit. Reputable shop.
I am extremely scared and now at a point where I am concerned the tune is a complete mutt and a huge Frankenstein mess.
I have purchased HPTuner and license to tune the L86.
I have some minor tuning background and a huge desire to learn.
I want a fresh clean start.
Is this a stupid approach? Is it better to keep working with the tune that currently has the jeep running and driving?
How does it run?
- Shifts fine. Cruises fine. Lack of power at certain points (produces about 320 RWHP with 40" tires on the dyno).
- Idle surges when in Park and in gear and at low speed.
- Idle surges crazy when A/C is turned on. It will actually die periodically while idling with A/C on.
- Mileage is horrible (but that could be the 40's and gearing - it is at 2,400 RPM at 75 mph).
I would love some thoughts from this group of knowledgeable people.
