I have made a overrun fuel cut feature to beta-code, but beta-code doesn't compile with gcc (yet), so I have to install codewarrior compiler (if it is free) and try to compile with that.

Hitting 'alt' or 'tab' doesn't help. It changes to 'crank' everytime I read settings from ecu.

I think tried that already, but I'll try it again.

Text 'warmup' stays there after burn, but when I fetch settings from ECU it has been changed to crank.

Hmm.. maybe I have to try decrease dwell time step by step with 0,1ms and use max spark duration 2.0ms, that should be enough?

Hi!

I'm running my coil directly with vb921, but I have problems to set good dwell time. with 3 ms it is okay but my v3 case gets warm (38 celsius degrees) after short run. With 2,5ms I get weak spark but no heat.

I think I need more tha 3ms to get best result, but then whole ms will probably melt ...

No it didn't help...

I decreased lag factor of rpm and got it littlebit more stable. I'm reading rpm from coil, so probably I can't get it better.

But back to the point:
- Is those spikes caused by too small X?
- is too long/short time of tau causing AFR to remain lean/rich for too long time?

Hmm.. I get lean and rich spikes when accelerating deaccelerating. Do I have too big X or is the problem in Tau?

When the coolant temperature reaches it's highest value (normally 160F). (It doesn't depend on the warm-up entry values being =100%)


Ok. Then THIS is one of my problems :). My engine is really small and takes years to reach over highest temperature value and sometimes - in winter specially - it ...

When does Cold accel enrichment go to zero?

ps. using MS2
