Did you do the cranksensor relearn?

 

[Johani]

no i did not

 

[scotmach]

You need to do a crank relearn since you installed a new clutch.

 

[five.slow]

Can't the new x4 do the relearn or is it still a ford IDS?

 

[scotmach]

The X4 can do it.

 

[Johani]

even if the car is tuned

 

[scotmach]

Yes, one thing has nothing to do with the other.

 

[Johani]

awesome thx

 

[Johani]

And just had a new update today for the X4:banana:

 

[Johani]

is it possible to disable the o2 sensor throug the x4 despite the fact that the tune was loaded by HP on a dyno

 

[Johani]

done disconnected the battery did the relearn and all is good
thx

How do u do the crank relearn im having the same problem but my check engine light stays on?

 

[helloWorld]

Basically, you have to let your car warm up to operating temperature (engine coolant temp ~ 190 F), and then the X4 will tell you to rev up to somewhere around 4100 RPM. As soon as the X4 detects the RPM where it wants it to be, the crank relearn is done.

Will the x3 do them same?

 

[helloWorld]

I do not think so. The only special function available for the X3 is the KAM reset.

Well that sucks... Thanks for your help

You are welcome.
