Hi To all

I need help with oscillation on idle hot restart, The megasquirt was Dyno tuned in February and it ran great in all aspects till about a week ago. If I stop the car for about 10 minutes and then I restart the car it starts oscillating, it only last for a couple of minutes before it settles back to normal. I have change the ASE as best as I could (was not to sure how and what to alter) and it made no difference.
I am begining to suspect the Idle Speed Control Valve.
Could somebody be so kind and have a look at my Megalog and current tune to see if I have missed anything.

The car is MX5 mk2 1998 1.8l, Running a m45 Mini Cooper superchager , EV14 550cc injectors, intercooler, Pushing 220HP at the fly etc.

Check the intake air temperature fuel correction, it will probably be pulling too much fuel out as intake air temp increases

I found the default curve too aggressive

Hi Arran

Thanks for your reply. I am a little green on Megasquirt, could you give me some guidance and perhaps an example?

Cheers Rick
