cranking speed issues

Post by ccmc »

Alright went to try and fire the motor after a couple of months of taking time off. The issue I have is the cranking speed is pretty slow. Around 160rpm which is a problem because i am getting spark but the injectors are not firing. I have a spare 36-1trigger wheel on a drill and i can get the injectors to fire at 200 plus rpm. I have my cranking settings at 150 hoping this would help but no go.i remeber reading somewhere on the forum about issues with cranking speed. This is an ms1extra with edis. Thanks for any help you guys can give.

Remember that the "cranking rpm" must be set a number of hundred rpm higher than the fastest cranking speed you'll ever see.
How did you set it to 150 though? MS1 only allows steps of 100rpm.
