Help with non-EMS EFI programming
Posted: Mon Jun 27, 2016 4:58 am
I have installed an Ecotrons EFi kit on my Ninja 250. I know this isn't the exact forum for this type of ECU, but nevertheless, its clear that there are several EFI experts here that might be able to help me. I'm not getting much help from the manufacturer.
Its been anything but straightforward. I have been working on it off and on since about 2011. I have most of the physical problems solved, however, that leaves me with a motorcycle that has a surging idle to the point where it stalls when warm. I disconnected the O2 sensors and it runs better, but the problem is still there.
The bike seems to run mostly OK until it gets warm. According to the log, the surging idle corresponded exactly with the startup of the O2 sensors (they don't work until the engine warms them up) which is why I unplugged them.
I need to be able to adjust the tables to stop the surging problem. If it had carbs, I would assume it was too lean, but the efi doesn't always work the same way. According to the log, it appears that the idle decays, then the ecu bumps the spark advance, then the idle resumes, and the cycle repeats.
I know there aren't too many ecotrons ecocal experts here, but anything to get me in the general direction would be appreciated.
Thanks in advance.
