Just in case someone else has experienced issues with WAR chip idles...
I have a '89 325i with a WAR chip and MAF (3 inch) conversion. I've worked through literally over 100 tunes trying to nail down a respectable idle and the closest I've come to is a small bounce between 900-1050.
The odd thing is my initial start-up idle is a rock-solid 900 rpm, which jumps to the above shortly after driving. ALL the physical engine issues are good to go (TPS checks out, and set correctly ICV spins and is fine, no vacuum leaks) and with previous tunes I've been able to get it to idle steadily but only at about 1100rpm. The chip simply does not respond to the "Idle speed" tab, so my present "good" tune is a modification of the tune Miller sent me. The map conditions that I've altered to find a "better" idle include the idle fuel, air temp fuel, and RPM limit, however I'd love to have a solid 800 or 900rpm idle.
Anybody?
