My basic question is: is the IACV purely ECU controlled or is there a passive thermo passage in it?

Is the cold idle speed actually controlled by the ECU via the IACV during warmup?

Dave

On my K20A2, with the Intake Air Bypass Control Thermal Valve removed, My cold engine idle speed is roughly 1500-1800 rpm until the coolant temp rises and my kPro4 controls idle speed to the 750 rpm set-point. Is there any way to modify the cold-idle set-point, or coolant temp at which the idle ...

I am using an ECU setup for a 02-04 RSXS.
Doesn't 107 have some special significance, like full retard or no sensor signal?

Dave

I have Cam = 107 and Cam cmd =0

The graph of Cam is very smooth and flat

Dave

Are you suggesting that the engine is idling and driving well with the actual cam timing off by 107 degrees? Also the Cam graph in Kmanager is a perfectly steady straight line at 107. I was hoping you could tell me that 107 is a typical reading when the cam sensor is bad or the cm-phaser is stuck ...

Thanks; I retested and see that E9 only goes down to 3 volts at key-off and if I disconnect the the O2 sensor connector, it goes to zero and the relay shuts off.

I am trying to understand why my EFI main relay won't turn off. This is a KSwap into a MR2 spyder with a KPro4, and I have the ECU and relay wired up properly to the KPro E7 pin, so memory power is supplied through the relay coil. I believe the ECU is supposed to internally switch to grounding the ...

I have a new KSwap (MR2 Spyder) with a 2003 RSX engine and am trying to get rid of P0341 (valve timing phase gap) error code. I am getting this with Cam sensor reading 107 degrees and the cam target value or 0 degrees. I there some special meaning to 107 degrees? I see that the KManager software ...
