Hi ,
I have a problem with a M800 ecu Gold box ecu running an Impreza which triggers cylinder 1+3 injectors when the engine is not running and throttle is opened past 90%
If I disconnect 1+3 injector it triggers 2+4 ,Ive disconnected every sensor other than the throttle position sensor and it still has the problem.
The injectors tick once as the throttle position shows 90 %
Tested with a scope which shows a a ground switching at 90 %
File attached ,havent tried to start yet as the engines a new build withe 1200cc injectors
Thanks Dave

If you don't want this behavior, make sure Adjust->Fuel->Compensations->Stopped Injection is set to 0. This table defines how much fuel (% of IJPU) is injected when the Throttle Position exceeds 90% while the engine is stopped. Intended for a wall-wetting priming pulse. I've never needed this.
Thanks for the response , its strange that it only triggers cyl 1+3 (right hand bank ) unless 1 + 3 are disconnected then cyl 2 + 4 (left hand bank ) are triggered
