Idle Air Control

The idle stepped does something, but I'm not confinced it's right. I connected the 4 wires from the stepper to the A,B,C & D channels (on the EC18 connector) going clockwise round the motor looking at it from the connector end. My stepper is an "anti-stepper" like Marcell's... It was operating the wrong way round at first.

Idle controls

Idle afterstart RPM (added value?) - Value to add to base idle speed when the car is first started.

Idle afterstart duration (s) - the duration to do the above for.

IAC afterstart (steps per 160 rpm) - don't understand what this is getting at.

Max steps to extend - total number of steps the motor can do. I managed to shoot the pin out of the end of mine. Don't do this as they get stuck in awkward places...

IAC step sequence - Lots of things, depending on how you wire up your motor. Mine was 201. ie drive C, then B, then D, then A.

stepper speed (ms) - Speed motor moves at. ie time between steps. 0 ms is fast and can shoot the pin a long way (see earlier)

iac_conf RAW - no idea! something to do with raw hex config?

See the IAC section of: MembersPage/MarcellGal/EngineSwap/AirFeed for more info. on config

I thought I'd cracked this. but I havent: I still can't get a stable idle without the engine racing. Hmmm.

[config goes here:]

Help!
