look at the ‘warm-up’ table – just increase the enrichment factor at the lower temperatures – it makes a BIG difference
It looks similar to the Idle Table but the Idle controls Engine SPEED while the Warm-Up controls FUEL Enrichment
The position for the IACV is actually set while balancing – with an already warm engine, you balance the TB’s and check the IACV position – it should be operating in the range of 30-35 steps when controlling at warm idle; if outside this range, adjust all the screws until you achieve both balance and IACV in that range. This puts the stepper in the ideal range for fastest closed-loop response.
changing the position in ‘tests’ does nothing while it is under active control – I’ve seen this claimed by others that this value will affect how it performs on overrun with closed throttle – my view is that whatever you change it to, it will be over-ridden in active control and if you go back after some time the number will not be at where it was previously set.
The other thing – recognize all that IACV does is adjust the air volume through the bypass ports – which controls engine speed – it cannot effect the fuel because there is no change to the TPS (unlike a Keihin system where the actual throttles are opening) – so the enrichment is does via the warm-up table.
