Hi all, I’m having hard times starting my car. When I used an oem chipped ecu it was starting fine, so I’m sure it has to do with the parameters I set, particularly the cranking parameters.

I used the k20 basemap from ecumaster google drive, but it won’t start my car. I reduced the cranking fule and set prime pulse table to 2ms at all coolant temps and the car starts but a bit hard.

Since it’s a 12.5:1 comp frank engine with 1000cc injectors, what cranking parameters can I adjust to compensate the large injectors?

Should I still enable “Batch all injectors”?  
Should I enable “Use injectors cal.”?

Any help appreciated.
