I have had it for over 2 years now on 2 different Rangers. I would say I love it 95% of the time. Most of the time it is just seamless extra power when your on it, and stock drivability when you are cruising. It has some "custom" tuning capability and logging which is nice if you want that, and can run different maps. My only gripe with it is I have had the short off time, hot restart limp mode issue that others have talked about in this post. Basically if I stop at a store/restaurant/etc and go in for say sub 5min, when I come back out and start my truck it will go into limp mode. I just have to turn it off and wait a bit and then it is fine, and this scenario happens to me maybe once every couple months, but still it is an issue that has yet to be solved in the two years I have had it. Hopefully that gives you some info. I can gladly chime in if you have any other specific questions.Does anyone have any time using the jb4 that would like to give a review? Can't seem to find much about it on here other than talking about getting it.
That is exactly the type of info I wanted to know! It seems like the best way to get a "tune" and still maintain the 5 year warranty.

That is a good point. I wouldn't plan on going above map 3. Most likely would only use map 1 for a slight bump. ThanksAs long as you don't dial it up too much it's great and doesn't drive-ability

Thanks for the heads-up. I am on the current stable build, and I saw in the change notes when it was "fixed" but the problem has always persisted for me. But I did not know about the staged start sequence. I will definitely make sure I do that from now on and hopefully that fixes that problem for me.There was an update for this.
I was also told to start in sequence.
turn key to auxiliary position. Wait 1 sec then start. If you get in and spin key there is not time for JB4 to do a hand shake with truck computer.
How many stored limp mode events do you think it would take to cause a dealership to be concerned?That is exactly the type of info I wanted to know! It seems like the best way to get a "tune" and still maintain the 5 year warranty. Thanks for your response.

Seems like that would be complete pain in the ass in a Lariat.There was an update for this.

I think you're correct with numerous limp modes. What I've read that has bee. Fixed with a firmware update so that seems to be a non issue.How many stored limp mode events do you think it would take to cause a dealership to be concerned?

Interesting. That does not sound good.I have followed the VW GTI forum since 2014. On this forum the JB4 unit is looked at as the best option for piggy back tune. So much that they hassled anyone running another option. I never used JB4 on my GTI but used Neuspeed Power Module for 2 years until I went with a software tune from Unitronic. On the Ranger I used an early beta model of JB4. The first unit was not wired correct. At first they wanted me to change wiring in plug, but after sending pictures they just made me a new unit. New unit went in fine and worked. I did have issue with communication with cell phone which was never perfect. I could change tune settings but could not receive all data that is displayed on phone app. Regarding engine performance it did a lot for Ranger. Big change. But since it did not change transmission the engine and trans never seemed to work well. Jerky. My GTI Unitronic tune had a program for engine and trans. Worked well together. Car now 7 years old.
Last Christmas driving Ranger down to Alabama I had engine go to limp. Checked all, nothing found. Turned truck off and back on. No errors. Drove another 10 miles then limp mode again. Not wanting to risk being stuck after hours and before Christmas I stopped and remove JB4. Start up and 9 months later no issues as I have not put JB4 back on. I feel I must have had a plug or wiring issue on JB4. Having a tuned GTI. I told myself to leave truck stock as it is my daily driver.
If I ever tune, I would use the Ford Performance tune. I understand it also adjust transmission which I feel is needed in Ranger.
As this being old I wonder if there was an explanation to be had. The Map options states Maps 3-4-5 are for E30 but this chart is all 93 Octane. What is the risk of running map 4-5 on straight 93? Knock or something worse?Yes stock vs. various maps on 93 octane.
