I had to remove my TN exhaust pipes to repair my damaged Hydraulic clutch line and install my SS clutch line. After I put everything back together my W/B jumps around from 7.4 to over 20 while the car is turned on. When the engine is not running but power is applied the gauge will read 20.0 like it always does and it starts up normally with no error codes telling me it's hooked up correctly. Anyone know whats going on? I have every reason to believe the car is running ok because well it's running ok, lol

 

Try recalibrating it. You didnt drop the sensor...did you?

 

nah I never took it out of the downpipe.

 

Assuming you have no leaks, then just try a re-cal, and/or the full reset procedure.

 

How do you recalibrate or do the full reset procedure? (yes I'm too lazy to search for it!!)...

 

You can do it driving. Get on a highway, get up to a good MPH and take your foot off the gas let it just cruise so the injectors are off and it reads like 20.9 - 02 on the gauge. Quickly press the control button rapidly 3 times, CAL should be displayed on the XD-16, then finally press the control button once more this initiates a free air calibration. I usually do this every 100miles to keep things nice and accurate.

 

Good to know Thanks Chris
