Hi
I finished the installation and loaded a startup map into the ECU, when i turn on the ignition the fuel pump primes up fine but when i crank over im not getting power to R2,
i Have checked the map sensor signal via the logger.
Could this be a crank sensor issue or ???
Any help would be greatly apprieciated
Regards
Mick
Good morning,
Does the fuel pump prime when you switch on the ignition?
As soon as the ECU senses RPM it should switch on the relays again which will give power to the engine components and fuel pump. If the relay does not switch on again it means that the ECU is not getting an RPM signal
Yes that’s correct and it does modulate between 200 ohms.
I checked the voltage at pins 6 and 12 they both are reading 9.7 volts
It’s an e24 harness red neg blue pod according to the drawings the black is either spare or shield
Can you shine some light on this dilemma
Mick
Ok, yes i am getting 9.7 volts from pins 6 & 12 on my E21 harness, is this repairable ?
or do i need another ECU ? If i need another is the Venus still available ?
If not will a later ECU accomodate my E24 & E21 Harnesses ?
Mick
In most cases it would be possible to repair the unit, you are welcome to send me the unit for inspection where after I would be able to quote on repairs
