Using factory ECU to control idle on NB8B plugin with e420c
#61
Look what I'm doing....wrong? If I set Aux 1 to 'None' then my idle sits at about 2k rpm and bounces. If I set it to how you see, it is about 1040rpm and solid (EGR port leak). My board jumpers are on the 'Factory ECU' pins.
What is going on here and why is it working for me? I might have been using closed loop idle this entire time, what a ******* n00b!
Either way, this has been working for me and I don't have any major issues with electrical loads, power steering or AC (when I still had AC and PS).

Well ladies i posted few issues on the adaptronic forum and Andy ended up finding a problem with the wiring harness. It appears that the air temp and the coolant temp outputs from the adaptronic board to the stock ecu are mixed on the NB8A harnesses. In other words when you set it up to read cold/hot the stock ecu gets the wrong signal so it sees air temp change however it does not get a coolant temp signal. Andy says to just flip the 2 wires. Before you start taring the harness apart, read this, take a small watch screw driver, open up the little slot at the bottom of the connector. It will come up a tiny bit, not all the way off. Then look inside the connector from the front (opposite of the wires). The important part is you need to lift up the plastic thing, this isnt like the computer connectors where you have to press down to pull the connector. There is a tiny plastic piece inside the holes that you have to lift up and then pull out the pin out of the back of the connector.

Well i installed the ecu again few hours ago. Guess what..the change i made to the harness works. Also the car starts like stock with the correct injector times and does not die anywhere. I'll be doing a detailed writeup probably sometime tomorrow on how to install the unit on a 99-00 and how to change the screwed up harness as well as posting a basic map for the stock nb injectors..
