ID1000 as Primaries with Rich Idle
 

To those running ID1000's for primaries, do you have an overly rich idle or if it started out that way, what did you do with the tune to combat it? Even tinkering with the fuel map doesn't get it to come down for me. I can't seem to get my idle any leaner than 11.0/1.

what EMS? powerfc may give you problems, but i ran 1000cc with haltech and had no problems leaning it out. iirc, p/w at idle was around 1.8ms for AFR 12.5-13.0. most injectors should be able to get down to 1.0ms reliably

Adaptronic select pnp.

Something is wrong. I have tuned several cars with id2000 primaries on the Adaptronic both pump and gasoline. Zero issues. I would email a log of idle and the ecu file to tech. It could be a mechanical issue too.

I'll send logs to adaptronic's tech mailbox, but in your opinion, what mechanical issue might cause the rich idle? Maybe I should test the IAC valve? Could improper voltages on the TPS cause the issue? I've often wondered if the calibration available to the adaptronic for the TPS eliminates the need to measure the voltages on the TPS and get them within spec.

I would make sure the ECU is in open loop( to eliminate an improperly setup target AFR map), then look at the ECU trim( to verify a coolant, or air temp etc map is not added in a lot of extra fuel for some reason- like a sensor stuck in cold or the map is just incorrect).

Mechanically if you are firing a secondary injector and a primary injector it will cause this. So one rotor is at 9 afr, and the other 14afr... but o2 reads 11, it wont' let you lean it out( lean rotor will lean misfire).

Timing is off, injector is dirty/clogged etc etc.

A rich idle that hurts throttle response? Don't think you should be tuning.

Good grief man, knock a guy down on a three year old post. In case you care, it turned out the be the map sensor hose was pinched making it run horribly. Aren't we here to learn? Good day mate!
