Pulling KOER codes

February 16, 2008, 10:09:00 PM

I'm not sure if this is normal, but I doubt it. I went to pull codes today and let it run longer this time to see if the koer test would complete. After it finished, the motor turned off and then I got codes 11 and 10. I know my old engine/ecu didn't do this so whats up?

Its a speed density ecu (da1?) that I got from Vinnie and it works perfect other than it acts weird/slow when pulling engine-running codes - slower than I remember on the original computer. Either way, now that the motor's running great, its about time to swap over to mass air.

There are no zeros in codes.

and,
never should you pulling codes cause the engine to be automatically turned off.

That is wiered.,, much more wierd than the slow output.

If your doing a KOER and the engine shuts off and the eec self test connector is still configured for pulling codes,, then your eec just went to open loop which explains code 11.

I always get 10 and 11 at the end of all tests? Engine off gives them to me also. I know its not a "code", but rather status. The manual that came with the reader mentions both of these. I'm still baffled on why the engine shut off though. It acted like it completely cut fuel or spark. After turning the code reader off, the solenoids disengaged so it was still in test mode when it turned off.
