Tsi-1 Posted April 18, 2015 Author Report Share Posted April 18, 2015 I don't understed why is power and the 2 wires all time and 1&2. Link to comment Share on other sites More sharing options...
scott87star Posted April 18, 2015 Report Share Posted April 18, 2015 Did the injectors without power on both leads move to 1&2? That was my question. I didn't expect it to start. To save time, with the key on BOTH injector wires should show 12v when plugged into the injector because the ECU grounds the injectors at the ECU to fire them. If you disconnect all the injectors and measure you should find 12V on only one side. If an injector is plugged in and only one side has power with the key on it means the injector is bad.

scott87star Posted April 19, 2015 Report Share Posted April 19, 2015 So what you describe voltage wise sounds correct, you know they spray as you indicated above, time to look further. If the ECU light is flashing while cranking then it is getting an rpm signal, can you connect your laptop to the ECU and take a datalog of what is happening as you crank? You can get free software to connect, go to www.efianalytics.com and look for Tuner Studio, the lite version is a free download. Note that tune studio may not have a configuration file for the old FIP firmware, if that is the case PM me and I can get you something. Link to comment Share on other sites More sharing options...
Tsi-1 Posted April 20, 2015 Author Report Share Posted April 20, 2015 Do u know what's is the diferents on the ecuF1 and f1-s..??Is anything to do the ignition adapter wiht the injectors no working ..? Link to comment Share on other sites More sharing options...
scott87star Posted April 20, 2015 Report Share Posted April 20, 2015 There is no ecu difference between F1 and F1-S, just the board. If you can take a datalog I can see what the problem might be. If the ECU doesn't see an rpm input signal it will not try to fire the injectors. Link to comment Share on other sites More sharing options...

scott87star Posted April 20, 2015 Report Share Posted April 20, 2015 I wouldn't mess with swapping things, you'd have to swap the processor out as the connectors are different. Link to comment Share on other sites More sharing options...

scott87star Posted April 20, 2015 Report Share Posted April 20, 2015 Nothing specific, just has to have a usb/serial port and you will need the cable as well. Link to comment Share on other sites More sharing options...
