Subaru G4 Storm RPM Limit Activation/Trigger Problem

Recommended Posts

Link G4 Storm Car is a 2000 USDM Impreza 2.5RS, supposedly it has a built 2004 2.5l UDSM Sti short block. The heads, coils, etc are from the 2000 2.5RS. Car is turbo. Car starts and runs, but in the 3000-4000 RPM range it is getting some kind of bad signal. The RPM limit activation is kicking on because the Link G4 is seeing the RPMs randomly jump to 10000+ RPMs. I tried playing with the Trigger 1 and 2 filter settings and voltage settings, but haven't found anything that makes it better. I have been able to force the motor past 4000 RPMs a couple times and it seems to clean up. The trigger mode is set to Subaru V1-6.

Hi

Can you please post or email your current PCL file so I can have a look at the trigger configuration.

Are you running wasted spark or individual coils? If wasted spark make sure you have resistive plugs and leads fitted.

I also assume you do not have variable can timing.
