Cold Start

Post by leafs31 »

Return the cranking fuel trim to 0%
- For Race calibrations only, alter the water temperature compensation cranking to:
This should work for both stock and aftermarket injectors.

Does Kpro have something like this I need something where my water temp is this much so we add this much more cranking fuel and if the temp is warmer we take away more cranking fuel trim.

When its cold and I change the cranking trim to add more fuel it starts fine but days when it warms up quite a bit then the engine is just flooded and I have to remove more fuel then.

Thanks

No it does not have this option. There are fuel compensation tables and cranking fuel adjustment tables though. This ecu works differently than a FlashPro.

I don't see these tables anywhere. Would they be under fuel trim all I see is Injector Voltage and Cranking Base Injector Pulse tables. I know where the fuel compensation tables are but need something for cranking, all I see is idle and light load stuff.

Hondata, you can make a separate tab for the cold start the engine as a fuel and for ignition in the K manager / parameters / cold start engine????
Below 300 rpm runs cold start compensation above 300 rpm runs standard fuel and ignition compensation. :oops:
This is required for ethanol and methanol fuel

I don't see that tables in KPro. What is the starting issue you have with alcohol?
