Thanks, I will check it out. Â Isaac

Hi guys, Does Link offer any training with regards to engine tuning. I am an auto electrician looking to offer more to my customers then a physical install. Cheers Isaac

Thanks Simon, That was a great help, Im not quite there though. I reduced the Min/Max clamp to 10/120.  I can get a nice 900rpm idle with the base idle figure at 85. It seems to start up in the right place now without getting higher and higher start rpm but Ive just got a little rattle still to get rid off when I shut down (as I turn the key off I still get 2 or 3 clunks from the ISC). I can remove the rattle completly if I reduce the Max clamp to 90, but it wont let me use 90 or 95 for my idle at cold temp to bring the revs up of coarse. Am I right in thinking that the Min/Max clamp is just telling the ECU how much it can move forward and back? If its the Max clamp that affects the shut down rattle, and thats getting too close to my desired base idle, do I need to move My ISC to the middle of its travel (for example) and then start again? Thanks for the advice.

Hi there, trying to sort out a Idle speed problem on a 1UZ. I have set up a Hold Power system but Im still getting stuck. I turn the Key on, the ISC travels all the way in and sits there rattling on its 'stops' for a few seconds. Car starts and I can adjust the idle base map fine to get the RPM around 900. Store and turn off the engine, the Hold relay stays on and the ISC moves all the way back out and rattles like mad at the other end of travel until a moment before the Hold relay releases, at that point the ISC comes off its seat a small way. I thought I was on top of this but the same thing happens every time, when I restart the car it idles higher then the start before. Its like its forgetting where the ISC ends up. I tried switch AUX 5 + 6 but that just makes it start with lower and lower rpm. So I obviously am doing something wrong here, the 2nd question is can I stop the ISC rattling on the end of its stops by reducing the hold relays active time or something? Thanks for your help
