slow to idle after start up?

Thanks C.jack, I bet it's that. I have got the settings bang on at 0.60v TPS and 0.72v at ISCV, but I bet it's the gap that's still not right. Going to make some adjustments on that. If I can't get it right, gonna probably rip it off and hide the cable somewhere.

Thanks again.

Ok, so I've reduced the slow to return to idle thing by tightening the ISCV nut slightly from .72v to .69v. and did the reset adaptations in tuneecu.

Now, should I also reduce the TPS position accordingly from the .60v that it is now to say .58v ? I don't if there should always be a .12v difference for best performance.

Just curious if anyone knows about this, thanks.

Ok, just need some knowledge here to try and get things set right.

I managed to get a 0.5mm shim and adjust the stepper motor to that gap exactly. Not really to my surprise was that I had it spot on at 0.69v, which is what it was before I played around with it and now is set perfectly with the tiny orange indicater tab hanging dead centre on the nut.

Now, my start up idle is still a bit high, but much better, hanging at 1500-1800rpm for some seconds and then dropping to normal idle of around 880-900rpm on my bike. This is better than when it was set at 0.72v, which is too loose for my bike.

My TPS was originally 0.56v before I raised it to 0.60v and am now wondering if this is still causing the hanging idle on start up. It's only on start up that this happens, no other time at all.

I don't know if anybody has a definitive answer as to the TPS reading in relation to the ISCV reading. Should I lower it to 0.57v and have a 0.12v difference? Would lowering the TPS reading a bit take care of hanging idle? Or could it be a lean condition due to my super open and super free flowing exhaust system?

Would like to hear some thoughts on this if possible. Thanks.
