Re: Issues after new Clutch & Variator -Help!!
1). I have kangaroo at low speed and gear, plus the reaction to my throtle command is kind of with latency (late) at any speed at any gear.
This is a big one, the selespeed runs a fly by wire throttle, if you put your foot down, theECU tells the throttle butterfly to open, if this is now not happening, or happening slowly, I would suggest there is something wrong with the ECU or the throttle fly by wire control system. The variator increases power at 300rpm by playing with valve timings, but if the power is late and then arrives that isn't a variator issue. It is a management issue.
2). The clutch is sometimes engaged (seperates) at low speed especially in traffic and without me to notice, i press the throttle to keep going and the rev gets rapidly high then a sec after, clutch disengaged and the car jumps!! I know the ECU has to avoid such phenomenon and that means something was wrong on the assemble side. I had been to the garage several times and he is not ignoring but trying to help without success so far. Examiner says nothing. We cleaned the throttle body (don't do it! is cause another effect of loosing iddle zero but this a different story that was fixed).
The clutch on a selespeed is operated by hydraulics and needs to be set exactly to the parameters set by Alfa, the clutch throw is vital to smooth gear engagement and release for smooth driving. The selespeed software has a number of inbuilt safety systems which are designed to prevent failure. One of these is to put the car into neutral and release the clutch in the event of some technical problems. If your car is doing this and then jumping back into gear or something similar, I would guess it is the ECU controlling the selespeed system trying to make your car run. It is based on interpreting the input from monitoring sensors and assumption about clutch plate position based on the factory settings.
I would suggest you find someone who knows the Selespeed system and has the examiner system and is able to use it effectively to look at the car, and set it up properly.
The MAF sensor, throttle body, fly by wire control and variator are all linked into electronic control and can all really mess with the cars behaviour. It could cost a huge amount to fix this piecemeal, go to an expert and get it all looked at. Looks like your garage have made a simple problem a lot worse!
