opel kadett c with 20v 4age

I went to visit Ali today.

re adjusted the base timing as it was a few degress off(nice of toyota to put up the degree info next to the timing gear :) )
Alpha-n / SD blend was not working that nicely so i set it to Alpha-N only and now it´s running real nice.

Sounds great and responds very nicely.

been running the car now for 3 months, all looking good, and now using it every day as waiting for new car to arrive,

so getting various issues sorted.

manly the icv never really had it working so decided to check it out, problem i have with switching on and off at idle

shows on in megatune,

its has two 20 ohm coil, and was wired like this

i would have thought the +12v would have been the middle connection? which ive tried but still get it fluttering on and off.

The middle one is +12v, one side opens, the other side shuts.
If its using the 20V config I did, then I have Dual Solenoid option enabled - this uses the two FETs adjacent to each other to flutter the IACV open and shut.

You could Disable the Dual Solenoid option Extras->Idle Settings General and select the FET channel that closes the IACV
then you'll have a range of control from the max RPM that you have with the IACV disconnected to when it is fully closed.

do you have a spark map?
if so could you post it?
We got grants car running OK so he could drive it back. but the spark map is weak.
we went on the safe side with that. we could not find any 20V black top spark MAPs.

will try and get it on soon

Yes please!  I bumped up ignition timing quite a bit, but I'm still hesitant to go too far.  I could not get the knock sensor to give me a reasonable output when tapping on the block with a spanner so I don't trust it yet.

Dyno is your friend.

Raising timing doesn´t give be best results
