Hi

Looking for some insight on reading the RPM signal in the datalog files. At this time, I'm unsure if these could be small misfires or poor RPM signal from the distributor.

Hello

I'm a bit stumped on how the engine is responding after putting the engine back together. The recent changes are a 4piston cnc race head with stock size valves and adjusting the intake cam to +2 and adjusting the exhaust cam to -1. While engine was out I also decided to clean up the wiring ...

options. Once again, when activating the FANC output, the fans will not turn on.

thanks for the reply

Ill try it and see what happens

Any reason for this? As we plan on moving ...
