I can tell you that as early as my 1998 Grand Prix GTP, I couldn’t start the car, then pull the battery with the car running. I remember you could do that with any car back in the day, but newer cars you can’t seem to do it anymore. With newer CANBUS vehicles, I have a had a few vehicles from...
It started working again as soon as I hooked the Aux battery back up and put F42 back in.
I get what you’re saying…there are probably a few dozen things that can set it off. I seem to be unfortunate that I am one of the oddities that the bypass just doesn’t work for.
I put it back to stock and it is back to normal. Had to replace the main battery and didn’t want to spend $125 on an aux battery for the start stop we don’t use, but is what it is. No errors for now…hopefully the aux is healthy enough that it doesn’t drain down the new battery until I get a new...
Everything on the fuse block checks out…just hooked everything back up as stock and unfortunately going to have no choice but get a aux battery to turn this stupid light off. God I miss old cars lol
I’ll have to check it tomorrow…everything else is working normal except for that, but I’m out of ideas lol. About ready to put an Aux battery in and be done with it if it continues doing it.
just this week I replaced the main battery and did the aux negative disconnect/F42 pull. Every time I start it, I get the Start/Stop unavailable message. This has gone on for multiple start cycles and 300 miles of driving…any ideas?
The 3.6 Pentastar isn’t a pushrod engine…it’s DOHC. You keep pontificating and arguing on the octane subject, yet you don’t even know the general design of the engine you are arguing about??
So does the tune come with both the engine and tranny tune?
If you can answer Livernois, is there anyway to do any “custom” tuning for the trans, i.e. rev matched downshifts in manual mode or quicker manual shift response similar to the logic on the SRT ZF8 factory transmission tuning?
I know...
Yup, mine has low rpm ping as well, and especially with it warming up it noticeably pulls timing under heavy load. Have an extended warranty to 75k but have been thinking of canceling it and doing the tune.
I believe it leaves a “marker” in the BCM that puts up a code the dealer can see. They can also read how many key cycles since the ECU has been flashed. If you want to be 100% sure you retain your warranty coverage for your drivetrain, I wouldn’t recommend tuning. Just MHO 👍🏻
Stupid question, since most of not all of us hammer on anything we tune lol, but during normal driving, has anyone with the tune seen any improvement in fuel economy?
The one thing that Bronco has that peaks my interest over my JLUS is the availability of that awesome 2.7 Ecoboost. Jeep really need to offer a solid, affordable, well powered option for the JL. While I do like my Pentastar, it lacks the low end grunt and is just slightly underpowered for the 4...
When they initially announced that sharp 7 speed manual, I was interested. When I saw pictures of it, I was ready to buy one. When they came out and said that the 7 speed, with a creeper gear that is purposes for off road would not be available with the 2.7 OR the Sasquatch package, I tapped out.
