Good Afternoon guys

I have spent the past month setting up my microsquirt module to run my turbo 22ret fuel only

i want to run 10psi

Sensors

GM 2 bar map sensor
GM Air Temp sensor
GM coolant Temp sensor
Ford tps - EB Falcon
innovate mtx-l wideband
Bosch 440cc Injectors 0280-144-968
50psi Fuel Pressure (tested) with el xr6 Fuel Pump

Microsquirt V3

It starts for a second then turns off i cant keep it running no matter what values i change i get a rpm spike from noise but it steadies out
i have masked it in many of my other trials but cant keep it running

Can some one more experienced than me please have a look at my attached tune and quick data log of ..cranking starting then dieing ..and repeat
Will pay if some one can do me a base tune to start this thing


Thanks

Try increasing the Skip Pulses setting. This will make it reject the initial noise burst, but may result in a slower start.

Also, how exactly are Opto In + and Opto In - wired up?
