Maybe up next, you demonstrate a few common tuning strategies to address the abnormalities mentioned in this video. |
I would love to but I have little personal experience with mechanical or electrical problems (luckily!).
The only issues I have really had are:
Misfire - solved by replacing the spark plugs
Boost leak - solved by replacing the spark tightening all clamps
Hiccups during light throttle - solved by disconnecting MAF
The rest has been due to the ISO FW being in its infancy and just tinkering with things.
In general you would get a very long way by double checking that you have the latest FW, that it matches your JB4 board, that everything is properly connected and that all settings are the default.
