    It looks like TPS or MAP based enrichment, which is something the MAPECU3 does as well, or at least it can be configured to do. In the old carburetor days, it was an accelerator pump function. When...

    Sorry, I am not familiar with the bug. What version of MAPCAL3 are you using and is there an easy way to reproduce it?

    That should be OK. What is the WB showing on it's display? Which WB do you have and which MAPECU3 input are you using for the WB?

    Thank you for the update, good to hear you are making progress. Not sure why it would lose firmware, essentially it would have failed a checksum of the firmware which implies a corruption following...

    You will get some fluctuations as the exhaust gas is not constantly the same AFR. The other possibility is electrical noise. What is your setup in terms of wideband, etc?

    Thanks for letting us know! Good information for people to try first.

    It doesn't sound like you are having much luck. I don't understand how the OEM wiring can be so messed up that it won't start in stock mode. The only thing I can suggest is you check the wiring...

    Good to hear you have your vehicle up and running.

    Regarding the EBC, have a read of the MAPCAL3 and MAPECU3 PDF manuals regarding the EBC settings. From memory EBC Pres is the maximum pressure...

    Sorry, no you cannot change the igniter from stock because the 7MGTE ignition signals from the OEM ECU are a little unusual. The MAPECU3 cannot drive ignition coils directly either as they are high...

    FYI, the MAPECU3 does not control the injectors but the RPM signal is positive. Are you seeing the rev counter on MAPCAL dashboard move?

    That sounds correct so it appears the MAPECU3 is working correctly and passing the spark signal through. I still think a good start is to make sure the vehicle starts without the MAPECU3.
  12. Sounds like you are making progress. :)

    I would suggest removing the MAPECU3 and checking the car starts and runs normally otherwise you could be chasing your tail.

    Also, what base table have you loaded into the MAPECU3 from MAPCAL?
  14. I'm not sure why you are not getting spark. Does...

    I'm not sure why you are not getting spark. Does the car run without the MAPECU3? I am a bit worried when you said you found 2 pins swapped on the 6 pin plug.

    Did you measure the voltages on the...

    Check the MAPECU3 wiring diagram as it shows two wires connected to the 18-way. The white is the top wire and that goes to the OEM ECU IGT signal and the white/black bottom wire goes to the vehicle...

    What you need to do is set your volt meter to DC voltage, probably something like the 20V range depending on the volt meter you have, and place the black probe on a ground connection (one of the...

    The LED closest to the 3-way is power so that is good. There is no error code that would result in only 1 LED blinking. There are 4 LEDs in total. I have attached a screen shot of the MAPECU3 PDF...

    I think we need to check some basics:

    What are the 4 LED's between the 3-way and 18-way doing? The MAPECU3 PDF manual tells you their function and if they are displaying an error code.
    What...

    Sorry, I don't quite understand the question. It is possible the previous owner has damaged the MAPECU3 and that's why it is not working. Anyway, it looks like you have started another thread under...

    Apologies for the delay responding, we missed this one. If you use the OEM MAP sensor plugged into the OEM ECU then you cannot use the MAPECU3 to adjust fuel. If you want to use the OEM MAP sensor...

    Sorry, we do not support the E46 because the OEM ECU has internal igniters to drive the ignition coils. That means we cannot intercept the ignition signals to control ignition timing.
