Jb4 problems

offwithYOhead · 09-09-2015, 01:25 AM

Hey guys, I updated my jb4 recently to ISO and updated the firmware at 5.8 and now my car is not reacting well. I changed all the things that was said to change and now it's not working well. But was working well before. It says I'm pushing 15psi but that doesn't feel like it at all. In 3rd gear it says I'm pushing 10psi. Anyone have any experience with this? Or they can send me a pic of their settings to see if I messed up on something? Let me know thanks!

post a pic of your user adjustments tab. There are default settings that are wrong and have to be changed.

Make sure your 3rd gear boost doesn't have a limit set on it, the diode you cut isnt still touching, I completely removed mine.

Posting user adjustment tab would help make sure you changed the appropriate settings.

And make sure you have the latest interface, I had the same issue and 3rd gear limit was not displayed, only 1st and 2nd. I update the interface and I was able to see 3rd gear limit and put it down to 0.

You still haven't mentioned about changing the user settings. There are specific settings for ISO and if you had not done this then this is the culprit.

Hex 5_9 was only created to eliminate the spontaneous gauge sweeps and this was an indicator that the unit was rebooted.

Just did, everything else good?

weehe126 · 09-10-2015, 03:38 PM

Change N20 TMAP and 6 Cylinder timing to 0. Do you have logs? Your Avg Ing is high. Also what map do you normally use.
