K20 no start with correct injector sizing

[K20RX7]

Hello there,

PRA ECU Uk Type R K20A2 engine fitted to my Mazda RX7.

Im having an issue where if i try and start the car with the actual 1000cc injectors fitted it cranks and fires but does not catch.

If i reduce the injector sizing in the kpro to the stock 310cc injectors it starts and runs.

Im using a rising rate fuel pressure regulator set to 45psi.

If i tap the throttle the car cuts out.

Why wont it start and run with 1000cc in kpro settings.?

Look foward to any help. Map attached

Did you set the dead time for the injectors you are using

Hello there.

Yes.
Deadtimes are accurate, they came with the set of brand new injectors. I found out later today that for some reason the hondata isn’t reading map sensor. Even when sensor and loom unplugged. It shows -29psi at all times.

Not sure if it’s a bug or if there is a fix for this

HAs the map sensor wiring been modified or touched in any way?
