An easy way to be rid of those annoying 3Ltr limp mode issues forever.

Doesnt quite work like this. The ecu has a map so if it sees a abnormally high maf voltage for a given parameter it will go into limp. For example if the maf voltage goes over 2.5v at 2000rpm with a tps under 60% and the map sensor is only seeing 5 psi it will go into limp.

The good thing about what mudski has linked is it can be tabled like an ecu so you can program for a setpoint so maf voltages between certain rpm say in 100rpm increments. So this allows you to control the output maf voltage to the ecu and basically tune limp out.

Also diesels work the other way to petrol. The leaner the afr the better. Rich afrs can and will kill a diesel engine. Only thing high boost will do to the standard turbo is kill it.

Ok I follow that.
What about early non-crds that only have MAF sensor and no MAP sensor.
Also that unit uses the low side of ignition coil for rpm sensing.
