JB4 is finally here

[Casey]

Thanks. Have had my tuner for about 6 weeks. Your video gave me the confidence to install it today. All done, just need to mount box and clean up harness with zip ties. Thanks again.

Let me know ur input on this and if you recommend it. Thx

I'm putting the jB4 on my rho on Wednesday. I'll let ya'll know once the truck catches on fire.

Any feedback?

You fill her up completely with E85?

No I mixed it to E30 which for our trucks is about 9 gallons of E85 on a full tank of 93.

That’s great to hear. How’s your truck running? And I’m assuming you’re on map 3 or 4?

It seems to really like the higher octane! Runs great. I haven't bumped it to map 3 yet. I am currently on map 2 but will do some testing this weekend on 3 and maybe 4. I was waiting for some more miles and an oil change.

I removed mine after about 4 days. If anyone wants to buy it, i'm offering it up at half price. I had an issue with my truck shortly after having it installed so i just removed it and everything has been fine since. Don't want to take any chances with the truck. I'm not 100% it was the JB4, could just be a coincidence. But if anyone else is looking to purchase, feel free to dm (it includes the bluetooth adapter). Plus just thinkin of the removal every time i go to the dealership just seemed like a pain.

What exactly were the issues that you were having with the truck?

Code PO68A - jb4?

Got this code today and rho had a dead battery. Jumped it, check engine light came on with this code logged by jb4 Note: jb4 tuner installed last week. Gonna have it removed and see what happens. Then to dealership i guess.

I had the same code show up right after I installed the DiabloSport. I cleared and so far so good.

$728 was total price. So half of that plus shipping.

Yeah I dont think it had anything to do with the JB4 TBH. There have been a lot of issues with these trucks and I think thats where the problem lies.

How many miles have you put on it since you cleared the code?

 

[RamFan]

Probably a 100 or so and multiple cycles.

Its a common code that is thrown when you disconnect both batteries. Its what you have to do in order to install the tuner.

well maybe it was a bad installation by my shop. All i know is that i had it for 4 days, came out from work one day and my battery was dead. first time i ever had any issues with the truck so i'm not gonna take any chances. Could have had no actual play in my issue but i'd rather be safe than sorry. Like i said, its for sale and only used for approx 4 days

Installed mine today. It’s certainly fast!

It’s absolutely awesome with the JB4.

My truck is in the shop for a blown CAT and they never mentioned anything after they read all the codes, he called me after they read them

are you all still having good luck with the jb4? thinking about pulling the trigger
