Jerky cruise control

[Ezra-RS]

Lately whenever I use the cc the car stars jerking. Don't have another word for it.. It doesn't keep a steady pace like it should and did. It's like you're constantly blipping the throttle and letting go again. It does kind of keep the speed that I set but is continually speeding up and slowing down.

Anybody have a cure for this problem? Or tips where to start looking?

It isn't misfiring a little is it ?

 

[Ezra-RS]

No never noticed it misfiring..

hhhm funny one never heard of that one before to be honest, mine sometimes feels a little funny at 50 mph in 5th but i put it down to wheel balancing ! only thing i can think of is something mechanical :S

Checked for fault codes yet ? might be best place to start !

 

[Ezra-RS]

Yeah I've been getting a fault now and then saying "throttle pedal position track 2 input" which I also made a topic for.. But I've been getting that error from time to time before the cc started acting up.

I guess all that had changed is an oil change and put on the stage 1 map.

Is this since you've done an RSTuner file by any chance?

 

[Ezra-RS]

Technically yes. I never use the cc much and this did occur some time after I did a rstuner remap.
I take it that could be the problem then? And more important, how can I fix it?

 

[Dan@SJM]

Remove the RSTuner map was the only way of fixing it I found.

 

[Ezra-RS]

Hmh.. That makes retrofitting the cc a bit useless then.. Think I will mail Henk to ask if there is a fix for this.

 

[Dan@SJM]

He did 3 revisions for me, then stopped replying to my emails.

 

[Ezra-RS]

Revisions in the map to fix the cc problem?

 

[Dan@SJM]

Yeh. Never worked. Removed the RSTuner file and went back to stock and it was fixed

 

[Ezra-RS]

Henk saved the day for me!

He sent me a cc retrofit specific map and it worked. After first startup the cc function didn't seem to work, then after that it did and has worked ever since.

So I'm a happy customer.
