JB4 M4 Issue

[jwilliams]

Hi guys. Had my JB4 installed for only a few days. Only running map1 atm due to no exhaust mods.

Earlier i gunned it in 1st gear. Changed to 2nd, when the revs randomly stayed high (near red line) and just stayed there, even though i had changed into 2nd the box said 3rd. Its was momentarily stuck in third gear and revving its tits off by itself with no throttle input at all. Maybe for 5 seconds or so. Then it all resumed as normal. I tried to make the car replicate it and could not get it to.

Anybody heard of this, experienced it. Iv checked for codes and do not seem to have any.

Any help would be great.

Thanks.

True story. Like bro, have you asked on ww.m4m3f80f82f83jb4troubleshootingforum.com? [some site we don't all know about]

Hi,
Its going to be hard to diagnose this issue since you do not have any logs or codes.
Also since you cannot replicate it , i cant be so sure that it is caused by the JB4.
But i will recommend that you contact Burger Tuning and see if they can help you.
