Thread is ^ page 2 is when Andy comes up with the wire switch. (I did the wire switch after i burned the bad gasoline and my engine was running normally if you were to read the first pages.)


Anyone have a wiring diagram as to which wires are for injector 1-4?

Here's a PDF file of the wiring diagram

hhmmm new order is 3421.. while before it was 1234 and the NB firing order is 1342.

So basically he moved it 1 cycle before that way it sprays half a revolution before the valve opens.

Cool, makes sense, this could probably fix my idling problem.

Andy just answered on the Adaptronic forum - this is only affecting NB8A and NB8B cars using their supplied plugin loom for the e420c - any other cars should be right already... :)

Idling problem Leo? are you trying to get the stock ecu to idle? Did you see my fix in my install writeup? ...2 wires are crossed in the harnesses we got so it wouldnt work for us.

What is your idle problem?

Idle does not stay steady. I have the old harness, so there are no pins to select to have the stock ecu to control the idle.

Is it not steady when the fans kick on or does that not make a difference? You gotta play with the idle controls obviously or perhaps ask Andy how to rewire it to allow your stock ecu to control idle.

Yeah I need to play with the idle controls. It's not steady when the ac is turned on. I'll ask Andy if I can rewire it to allow the stock ecu to control idle. Thanks!

BTW....currently putting my car back together, rebuilt my engine. So I can't play around it until I finish my car.

Please report if Andy found way to do this. I also have that old harness with just wires, no pins.


I also switched to a 250 cell map. Idle is now much better!

Slightly OT, but I've been battling my idle since moving the ECU to the track car '90 chassis ('04MSM motor and harness). It dawned on me tonight that the neutral switch is 'talking' to the 1.6 harness and the adaptronic doesn't do any idle control if the neutral (or clutch) isn't in. Anyone with an engine swap with significant wiring work should remember this :idea:...

Post me your map, i think its an easy fix. There should be a tab to disable the out of gear overwrite. Check near the throttle off overwrite.

I don't have the laptop with the map handy but I already ran a wire to the neutral switch. Any idea where this tab was? My install instructions are 3 years old so maybe the newer revisions have the option that I haven't noticed. The older instructions were very clear that you needed a neutral/clutch switch to control idle.

Yeah you don't any more. What Firmware are u running on that thing?

I'm running whatever was current around the fall of 2010. I have the latest and greatest downloaded but I wanted to get everything sorted before I load it. Too many variables can spoil a party faster than outdated firmware.

Mine won't start with the new wire configuration

How many times did you try to start it? i did notice mine was acting up while cranking from a hot start (usually 3rd crank started it) but i didnt know if this was wires or me switching to 250 cells map.

Maybe 4 times at 10 seconds each. I reverted the changes and started up like normal. Kind of disappointed :facepalm:

Cold start on all attempts as well as the successful one.

Are your injectors batched during cranking?

I can't remember, it's been a while since I've had a laptop hooked up. Should they be?
