MX5 Mk2 Hot engine Idle erratic.
The following only happened after I upgraded from V3.3.0 to V3.3.0
The cold engine start is great I have no problem with that. my main idling problem is when the engine is hot. Been out today using auto tune in Tunerstudio, thing went well. When I got back I stopped the car and after a few minutes I restarted it, the revs went to about 1500 RPM and then down to 650 RPM and back up again to 1500. This happened for quite a while going up and down till after period of time it seemed to settle down to around the 840 RPM mark. I have had a play around a little but no avail so if somebody can point me in the right direct I would be most grateful.
My setup:MX5 mk2 1.8l 1998. Reverent Megasquirt 2 extra v3.3.2. Supercharged with a Mini Cooper M45, 15% reduced pulley. Intercooled. Larger inlet valves and head de-shroulded. Dans Ev14 550cc fuel injectors. AEM wideband. Coolant re-routed.
