des90 Posted December 13, 2010 Share Posted December 13, 2010 I have set Megasquirt up on the 90 and it runs great! The engine starts from cold and runs up to temp without touching the throttle.If then you switch off and leave cool down to mid temp and then restart the idle fluctuates between 600 and 1200 rpm until the engine is rev'ed to 1500rpm for a few seconds and then released to idle.I have an Innovate lc01 wideband lambda fitted and the flucuating idle seems to be linked to the lambda heating up and setting itself- Anybody got any ideas?

Hybrid_From_Hell Posted December 13, 2010 Share Posted December 13, 2010 Prob fine tuning needed between Warm Up Enrichment, Closed Loop / Tick over settings / PWM Settings and Coolant Related air density settings which helps with Heat Sink effects You could do some screen dumps of the above areas and post up Nige Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 13, 2010 Share Posted December 13, 2010 Do you have closed loop running turned on below ~1500 rpm? You probably don't want to as it will cause hunting like that. Quote Link to comment Share on other sites More sharing options...
des90 Posted December 13, 2010 Author Share Posted December 13, 2010 I'v had it on open and closed loop and tried the warm up enrichment up and down.One thing i have noticed is that the faster cold idle rpm doesnt kick in till its been rev'ed and running for a couple of mins.At mid temp if I switch the ignition on and wait until the lambda has set up it starts perfect?
