Hi,

i have purchased an OBDII cable to connect my GTA to the PC. This week i´m going to buy an Alfadiag license to be able to use all the funcionalities.

I need make the Selespeed calibration, but i don´t know how to do it....

The process of Alfadiag calibration is the same as with examiner? Can anybody explain it?

Lot of thanks

Is all the process automatic? Or you may operate with your hands on clutch measurements?

Thank you!

The main calibration process is fully automatic.
You just sit there with your foot on the brake and wait for it to finish.
The adjustment of the clutch pushrod (not sure if this applies to the GTA Selespeed) is not automatic because it actually involves spanners and someone moving them.

I have saw in the Alfadiag help this option:

Enable AutoAdjustment of Clutch

With this option the process is automatic too, isn´t it?

There is a fine tuning of the clutch biting point, which may be that.

It usually isn't needed and I have never tried that option on mine.


Give it a try and tell us what happens... :)

Thanks for all David.

My GTA jerks in takeoffs when the car is warm, when it is cold it runs perfectly.

I want Alfadiag to see the possible errors and make a calibration, do you know if it will improve the behaviour after that?

Will be the first recalibration on my GTA, it has got 47.000 kms.

It should improve.
Ideally it should be calibrated at every service.

I've never done the clutch calibration.
I've only done the EOL Selespeed Calibration routine.

David, the jerks when mi GTA is warm were solved changing the Electrovalve of the clutch.

I have not calibrate my Selespeed because the official dealer done it when they changed the electrovalve. But now here is my question:

I have test some GTA Selespeed and i think mine doesn´t work perfect when I start the movement.

It doesn´t jerk but in others it seems "the clutch" is a little bit harder or something similar because is easyer to startoff.

Maybe it need a clutch adjustement....how can I see the clutch measurement?

Hi!

Any idea about calibrating Selespeed with Alfadiag?
