- 2019 Jeep Wrangler Rubicon Firecracker Red (2 Door) - 3.6L V6 24V VVT Engine Upg w/ESS - 6-Speed Manual Transmission
Hello Superchips @Superchips JL !
I've been looking at your F5 Flashpaq for the 2018-2019 Jeep JL Wrangler. I was wondering if this tuner will fix the below problem I've been having......
My 2 month old 2019 Rubicon (3,500 miles) is having issues in the 40 - 45 mph range. It kind of shakes, sputters, kind of skips in that range.......whatever you want to call it. I cant comfortable leave it at 41 - 43 mph in 3rd. 4th is acceptable and doesn't do it as bad but 3rd is not good. I have a manual transmission so not sure why it would do this. Couple of others on here with manuals have had the same experience so I’m not the only one. Automatic would be understandable as I have had a few friends have their jeeps in for issues with their automatic transmissions. If I take off pretty normal and go all the way up to 50-60 mph with no hesitation no issues at all. But most of the time I get behind someone doing exactly 40-45 mph which causes my Rubicon to jerk right around 42, shake or run rough. It's at the proper shift points so that's not the issue. I have had manuals my whole life (2017 Manual JK Sahara before this)so I know how to drive them. It just doesn't run right in the 40-45 mph range. Hums and runs like a tank on the highway 70-80 mph. Perfect from 1-35mph and 50-80mph. 40-45 in 3rd just seems to struggle to run smoothly. Went to the dealership twice and had them hook up my Rubicon to their computer and scan for any codes. Sat there with him and watched as nothing came up and everything is normal. No codes came up. So I took a sport on the lot for a test drive and it did it exactly at 45 mph in 3rd gear. Probably cuz the gearing is different between the Rubi and the Sport. The oem tune I think is too lean. Only thing I can think of. Other than that it’s pretty cool but just get irritated at 42mph.
Thank you for any information you could give me.
