ECMlink Problem i with ecmlink CEL

[ChristianEclipseAuto]

Hi everyone,

I recently bought an ECU with ECMLink already installed, as I wanted to upgrade from my Black Box.

My car is the Japanese-spec version from late 1996.

After installing the ECU I purchased, the car keeps throwing an injector malfunction error for cylinder 2.

So far, I have replaced the resistor pack, swapped the injectors around, and reinstalled my original Black Box ECU, which works fine.

However, with the Black Box installed, the AFR fluctuates between 11.2 and 14.5 at idle, and I can hear the fuel pump (Walbro 255) changing speed slightly, going up and down.

I have had the ECU checked by an electronics specialist, who couldn't find anything obviously wrong with it. However, he suspects that the injector driver itself could be the issue.

I have also gone into ECMLink and tried activating and deactivating the individual injectors, and they all seem to respond correctly.

Does anyone have any suggestions as to what could be causing this issue?

Any help or suggestions would be greatly appreciated!

Thanks in advance!

The one thing that comes to mind is maybe a mismatch of the crank/cam sensors. What year ecu is the ecmlink one? And what cam/crank sensors are you running?

We usually turn off random misfire detection in DCT's to eliminate issues with cam/crank signal issues.

Post a log so we can see your settings.

Thanks for the quick reply.

Unfortunately, I have no idea what year the ECU is from, and I'm also unsure which crank sensor I'm currently running.

However, I am running an inverted cam sensor (not the big black one mounted on the side of the head).

The Black Box ECU runs perfectly fine without any issues or CEL codes. But as soon as I switch over to the other ECU running ECMLink, I get a CEL with a malfunction code P0202.

I've tried changing the settings in ECMLink about “non 95/96), but it doesn't seem to make any difference.

One thing I'm wondering: would it be okay to simply turn off the misfire detection? Or could that potentially cause other issues?

Yes turn off misfire detection, it won't harm anything.

post a picture of the ecu number and a picture of your cam sensor

I’m assuming when you switched your cam sensor from the factory one you swapped plug wires around or something?

No the car came like this from the Japan version E-D32A. The fire order is the same as all the others eclipses from 95-96. i am switching fire order everytime I need to use the blackbox.

I did swich the injector wires from the guide from the eatsleepdsm forum when using the blackbox, but I changed them back again when I was expecting to use the ecmlink - it follows the original diagram from 2g now. And the blackbox still works - I Never felt the difference.
