I would start reducing the variables in the system. First, power everything from your 12V power-supply. This allows constant injection times for a certain rpm and also keeps your ECU permanently connected to the Laptop. The Laptop-Sw certainly has some form of recording of all the sensor outputs ? What's the flow-rate of the injectors ? Are they original ?
Does that engine have an idle stabilisation valve? Did you wire it up if there is one? I think most efi set ups have them, also called an anti stall valve.
Hello again Mr Cotswold. There is no idle control valve as that's meant to be taken care of by the Drive By Wire setup. I was also trying to keep the revs up with my foot - no no avail unfortunately
@Mr_Spegru ah yes of course. It's that part working from the ecu then, and it's not thinking for itself and catching the stall or is it that you need to give it a little more idle speed?
That tick over sounds far too slow. Try 950 rpm. (You’re allowing the otherwise very healthy sounding engine to distract you from other more important parts of the project), -which is very frustrating for us!

Sounds like fuel starvation....but I'm no expert on efi engine's.

Yes - but why?
