So I am using ecmspy for the first time. I have installed a race ecm and am trying to do a TPS reset. Problem I am having is when I back the idle adjustment down it will not go as lower than 2.7%. The throttle body is free and clear, the throttle is twisted forward and I can not get it to 0%. Any ideas? I am new to this so I hope I am missing something obvious. Thanks for any advice!! |

False tps reset? How did you and how did you know you did that? |

well if it was not at 0 then it is a false tps reset just like i did. |

Ok, I'm trying to reset my TPS ('02 X1) and I have a noob issue... I can't find the adjustment screw/cable/whatever it is. I know it's on the left side (does that mean left when looking at the front of the bike or sitting on the bike?). I don't have the air scoops, just a forcewinder. I've searched high and low, and can't seem to find anything beyond "it's on the left side, near the air scoop". I couldn't find pictures or video of it, and my manual doesn't seem to be particularly helpful either. I also might be going blind? Can anyone give me a pretty detailed description of where I can locate it, what kind of tool(s) are required to adjust it, what I might need to remove to find/get at it, and/or a photo? Thanks in adv! |

It has silver allen head with a knurled outside so you can twist it with your fingers. Mine was originally on the left side (sitting on the bike) between the cylinders up near the tank. I moved it to the right side so it would be easier to get to. If someone buried it you could take off the tank to find it. It ends at the throttle linkage on the throttle body. Here is a pic of what it looks like (yours is on the other side, pic was after I moved it) and the second photo shows where it goes to on the throttle body.
I also found mine hard to turn.. a tiny squirt of wd40 on screw at the throttle body will make it much easier to adjust. (Message edited by NwRider on July 27, 2011) (Message edited by NwRider on July 27, 2011) |

Sweet ... I found the base of the cable, near the throttle body, and was thinking I was supposed to worm my way back and spin the cable tensioner itself. This looks much easier. Thanks for the visual aid! |

Your TP zero setting should correspond to throttle butterfly fully closed. If you see a value greater than zero then the previous TP setting was not correctly calibrated. You should be OK as long as you reset the TP with the TB fully closed. I don't understand why your idle is all over the place without touching the throttle. |

By all over I meant.. cold it was low.. barely run on its own (cold start enrichment issue?). I had to turn up the idle to keep it running on start-up. After it warmed up I turned the idle down. After riding a bit it crept back up again? |

Your welcome robot... I couldnt find it the first time I looked either. It had gotten tucked behind some wires and was hiding from me. |

My bike is also a little cold blooded and needs a bit of hand holding to maintain a good idle at start up. You could try playing around with the cold start enrichment values to see if you can improve the behavior but don't be disappointed if you end up accepting this as a "character" of this motor. I did. |

I can accept it if I have to... but prior to the ECM swap it fired right up and idled with no problem.. even on a chilly morning. |

I felt exactly the same way since mine also fired right up and idled no matter what before I switched to Race maps. There are a number of folks who also had the same experience. I finally gave up after playing around with the enrichment values and fuel map values in the idle area, etc. I might try again this summer see if I can get it "fixed". Let us know if you get it figured out.. |

I adjusted the f/r ignition advance at idle stock is 5 degrees race is 3. Idles nice at 5 or 6 like stock 1000rpm. 3% throttle opening. |

I threw my stock ecm back in the other night just so I could go for a smooth, non back firing, non decel popping ride. With an intake and exhaust it purrs like a kitten on the stock maps.. just loses some of its mid-range torque. I am getting the feeling the stock maps are closer to where I need to be than the race maps. I am debating using the stock maps as my starting point rather than the race maps. Of course I want as much oooomf as possible but... I want usable, street-able torque. I do love to tinker with my X1 but I like to spend more time in the saddle. Hehehe. I JUST WANT ENOUGH TORQUE TO MAKE MY FRONT WHEEL TO COME UP UNDER THROTTLE.. Well that and a smooth startin and runnin machine. Is this too much to ask? |

reset the TPS when the engine is HOT. Turn out the screw until the throttle butterfly *just* catches when you open it with the grip. Let it SNAP back. Reset it then. Also reset the AFV setting (Adaptive Fuel Value) at the same time. Stock idle setting is 1050, at least all this is true on an XB |

"I threw my stock ecm back in the other night..." Just keep an eye on the AFV to see if it goes up. I'd be surprised if you can maintain a 100% using stock maps with aftermarket exhaust and intake. Now as for improving the cold starting idle, I did an experiment by using near stock values (which are lower) for the Race fuel map cells in the idle area; six cells corresponding to 800, 1000, 1200 RPM and TP values of 10 and 20. Guess what. No more holding of the throttle. Try it. It may work for you too. |

Thanks guys. Think I will play with the race ecm some more today. |

I loaded my blended map, stock values on a race ECM below 3000 rpm, went for a spin and moved the race ECM map back in and bumped f/r timing to 6 degrees at idle. It feels much crisper than stock although stock seemed to run happier in the taller gears below 3 k. The solution. 4 th and 5 th won't get used below 3 k. |
