iceberg1234 Posted April 27, 2013 Share Posted April 27, 2013 Anyone have any experience with a Zetec 2.0 and a GEMS ECU. The car I just bought has this setup, but is way out of whack. It runs, but is so rich it burns my eyes. I have the gear to tweak the ECU, but wondered if anyone has a decent map I can start with. I'd rather not have to build one from scratch.

Croc Posted April 27, 2013 Share Posted April 27, 2013 Hi Paul - Have you also posted in the Birkin Yahoo forum? Quite a few owners there who do not come on here. Link to comment Share on other sites More sharing options...
pi7ot Posted April 27, 2013 Share Posted April 27, 2013 You may want to check if the engine temp sensor aka coolant temp sensor is within electrical spec. They tend to cause an over rich condition when they fail. m Link to comment Share on other sites More sharing options...
iceberg1234 Posted April 28, 2013 Author Share Posted April 28, 2013 Croc, thanks, I posted there per your suggestion. Pi7ot, I assume I just check the resistance cold and hot? Are there some standard numbers I should be looking for, or are they specific to the sending unit? Thanks Link to comment Share on other sites More sharing options...
