TSX Kpro with Idle problems, Can I use the K20 idle valve?

Hi, I have the TSX dual ecu Kpro and Im having problems with the Idle, in one of three redlights the idle dips and dies, and I get a rough idle woth AC on. I have turbo and Im running RC 750cc injectors with the fuelpressure raised to 63psi.

So it is duable to use the K20 idle valve too? I know that I have to fabricate something for the idle valve to sit on, and two hoses, one IN and one OUT to the manifold.

But is it gonna work to set the idle at 900rpm in Kpro? or is the two ecus going to fight about the idle?

This is not something we have tested or can easily answer. You can try it, but Doug is currently working on a modification for the dual adapter harness which should help with idle.

Im running a dual K-Pro on the TSX also and had rough idling... I set the low speed fuel col 3 and 4 / 750 and 1000 at 748 (running about 12-13:1 AF) and the rough idling disappeared... With the AC on there alittle bit of vibration but thats about it... I have a 5AT though and running w/o FI... Sometimes the rough idling might appear after driving for abit but it goes away after a second or so...
