no spark

[AdamW]

Okej. Det spark and sync error is fixed. But i hace one more question.
How do i set dead time comp and how do i set if i have low or high impedance injectors?
i have siemens deka 3145 788 cc injectors.

Your injectors are low impedance, ~2.4ohms.
These settings should work reasonable:
Set IJCU to 3.0amps (assuming you have only 4 injectors)
Set IJbc to -1
Set injector dead time comp table up like this:

Thanks adam.
i think ijcu should be 4 amp if i read the info on the injectors right.

Okej i have 2 more questions now

can i calibrate gm 3 bar map sensor ass 300?
Why does motec whant me to connect ign 1 to Spark pluggs 1 and 3 and ign 2 to 2 and 4. I am driving with waste spark and ignition is 1 3 4 2 i cant get it. It should be 1- 4 and 2-3 help me understand.

Hej Andreas.
Can you draw a picture, of what the numbers mean at the engine and at the ECU...

Yes, 300 is correct setting for the GM 3bar MAP.
For your firing order have you set up the table at >General setup>firing order with your correct firing order?
You are correct that your coils should be paired ign1=1&4, ign2=2&3 so don't worry too much if these are displayed/labelled incorrectly in the motec software, it will still work ok.

[andy_hstad]

Okej then tthen the motec electricel drwaing whas wrong.

thanks for all your help. Now i can try to start the car.

... so don't worry too much if these are displayed/labelled incorrectly in the motec software, it will still work ok.

injectors too?

[andy_hstad]

okay new thought. Once I have set the fire order 1 3 4 2 and run the injectors test cylinder 2 is 4 and so on. if i set the fire orders 1 2 3 4 everything is just right. If I test the injectors 3, it is cylinder 2 but all connections according to electrical diagram. Any explanation?

[SprinterTRD]

The Injector outputs 1, 2, 3 & 4 are names of the output ( and the order they operate )not the cylinder number.

The docs says wire them in firing order
so
injector output 1 = CYL1
Injector output 2 = CYL3
injector output 3 = CYL4
injector output 4 = CYL2

When you set the firing order in the software it does nothing to the outputs, it only changes the labels in the software to match the actual cylinder.

IE makes more sense to know you are adjusting CYL4 rather than injector output 3 ( which is CYL4)

Well I thought the order was firing order, so we got insight.
