I just finished putting my X1W back together and used ECM Spy to flash my ECM with the Race ECM eeprom kindly sent to me by a member here. I removed my PCII to re-flash the ECM, mind you it's been a few years since I had used the X1W but it doesn't seem to deliver the same kick as with the PCII and there appears to be a bit of hesitation at times. Is the Race ECM eeprom OK for the Forcewinder intake and Force big bore exhaust? Is anyone else with the same setup seeing the symptoms I'm seeing? It does take a while to warm up (having to hold the throttle open) but I can live with that. Also, I had a small plastic plug inserted in the extra hole of the Forcewinder filter. It got sucked in, what are the chances of engine damage (it probably went right through)? Thanks in advance for any input or help. ps. I bought ECM Spy about 1-1/2 years ago, is there anything new about it that maybe I didn't get? Thanks | ||

If it makes a difference at all, I also reseted the AFV to 100% (it was at 77.9%) before starting the bike. Maybe the ECM needs some time to adapt? Thanks | ||
| Firemanjim |
Ouch 77.9 % means it was leaning out the fuel map something fierce. It will definitely need to relearn.If that continues you need to get it to a dyno to see why it is running that way.} | ||
| X1_rider |
The 77.9% was with the PCII, I'm not sure if it makes a difference. So are you saying that maybe after riding it for a while with the AFV back at 100% it may be OK again? What is your opinion on that little plastic plug that has been sucked in? Thank you for your input. | ||

I have found that with the race ecm you will need to continue to adjust ride adjust where you are having problems with your map. Might wanna try a TPS reset as well. | ||
| X1_rider |
So by adjust you mean it will self adjust as I ride or do I have to change the values in the maps themselves? I will do another TPS reset and re-check the static timing as well. Thanks | ||

1) ECMSpy is free...I hope you didn't pay for it. 2) Not a ton new, for what you need it to do, a 1.5 year old ECMSpy will work great. 3) Re-set your TPS. 4) Re-set your AFV to 100. 5) See how it rides. 6) Read the big ol' ECMSpy tuning guide front to back about 10 times and then start data-logging and adjusting your fuel maps! The Force exhaust is a bit of a beyotch to fuel correctly. It will take some tuning to get it right, but boy is it sweet when it's right! | ||

No one seems to care much about that plastic plug that got "sucked" in...!! I'm curious as well since I have also plugged the "extra" hole with a little plastic plug except mine is still there...Or was the last I checked...  | ||
| X1_rider |
OK, thanks for the advice. Regarding the plug, I'll check compression in each cylinder, if they're the same, I'll assume it went right through without causing any valve damage. | ||

You need to ride the bike at steady throttle around 40-60 MPH for about 20 minutes to let the ECM learn. The ECM must be operating in close-loop mode for learning to take place. Open loop is strictly done by the lookup table stored in the ECM. When you're at WOT or anywhere else outside of closed-loop, and you're having issues, it means your map needs to be tweaked. | ||
| Firemanjim |
The early bikes had an extremely small area of "learned fuel" compared to later XB's. They kept giving the bikes more computing power which gave it more "range"--- lots more areas of rpm vs TP setting.Too bad I do not have an early bike here to look at a map and tell you where that area is!! | ||
| X1_rider |
I rechecked my static timing, it's OK, I checked compression, both cylinders around 170-175 (I guess my plastic plug didn't hurt anything). I only rode about 1-2 miles yesterday and my AFC was at 85.6 (I had reset it to 100%). The front spark plug was pretty whitish, the rear one appeared ok. I can't make heads or tails of this. Maybe I'll try re-flashing the Race ECM eeprom, the bike felt "flat" (maybe too lean) and the front plug being pretty white, maybe the flash didn't take and I was running stock program??? This is confusing. | ||

I almost feel like throwing in the towel and sticking my PowerCommander back in there. I noticed that the PC tables are "0, +2, -10", etc... The PC only adds and removes fuel, I was wondering if I use ECM Spy to change the values in the tables by the same amounts as in the PC tables, am I gonna get similar results? Also if I copy the cold enrichment values from the stock ECM and copy them in the Race ECM tables, am I gonna get better warmup? Thank | ||

the bike is running rich in closed loop, hence the ecm reducing the AFV to compensate (reducing fuel from 100% to 86 %) possible IAT or ETS sensor problem (what are the temperatures in the ecm runtime tab, do they match the air and engine temps)) dirty filter, lambda problem(have you used silicon anywhere in the intake/ exhaust headers ?) also check the wire where it enters the sensor, injector over fueling, try swapping them over to se if it makes a difference. or just the fuel maps need adjusting for your set up. those are the things i would look at but i am no expert. Hope you have better luck than me, i cant get my x1 to run ! | ||

The AFC was not 100% but how was it running? Perhaps the Oxygen sensor is telling your computer some lies? | ||
| X1_rider |
Thanks for the input. When I put the bike back together I put a new O2 sensor and a new head temp. sensor in. I checked the resistance on the air temp. sensor and it was good (it does show the right temperature in the runtime tab). I didn't use any silicone. When the AFC was at 77.9% it was running good but that was with the PowerCommander inline. Maybe it just needs to adjust, I took the PC off and re-flashed with the Race ECM all at once, maybe it just needs to recalibrate itself. I'll check my intake seals, that white front plug might indicate an intake leak. | ||
| X1_rider |
One more question. While checking static timing, I put the bike in gear to turn the engine over and align the timing mark while monitoring the CPS output. As soon as I put the bike in gear, the connection to ECM Spy cuts off, it only communicates with the bike in neutral, is that normal? | ||
| Snowbees |
i think that may be something to do with the sidestand/clutch safety switch. i have bridged them on my bike. | ||

+2 on what firemanjim said Get it on the dyno and get it to someone who can tune it with ECMSPY! After my motor build i actually shipped my whole bike down to California To firemanjim and the guys at JTSperformance! It was totally worth every penny! And they did an awesome job!!!!!!!!!!!!!!! | ||
| X1_rider |
That sounds like a good idea. I have a guy in Pennsylvania who just tuned my 2 Harleys (did such a good job on my FatBoy, he snapped the drive belt, haha!). Maybe I'll send him the Buell. I just wish I could find something temporary to ride it this summer. I'm thinking more and more about putting the PowerCommander back on for now. I guess no one has a good tune for that setup. | ||

Acouple of quick points the two plugs read differently front white, rear brown, air leak ( rear plug is nice fluffy brown with grey ash on the metal ) front is white with almost no ash, may hang at high idle at times intake air leak most likely either at heads or around the injector nozzles injector leak front cyl is not leaking air but the rear injector is leaking and the rear mixture is rich the ecm is compensating and leaning out the front. but cant lean out the back because of the leak not common, check the intake seals. | ||
| X1_rider |
Good point Oldog, I'll put the propane torch to it and see if the intake seals (esp. front one) are leaking. | ||
| Hamlin |
Hi, I have see you have share good of your information and ideas which is most nice to see it here and its good for me and others also thanks!! internet chemist | ||
| X1_rider |
I found out why my front spark plug was white. I bit the bullet and removed my fuel tank for the 20th time to remove the throttle body. Check out the front intake seal, it looks like it was pinched between the intake manifold and the head, no wonder it was sucking air.  While I have the TB on the table, I'll change the injector o-rings. | ||
| Oldog |
good idea for tuning all sensors must be correct I would return the system to stock condition, the PC will just skew the afv in the closed loop, the concept does not work well with buells, I gave the one I had away. with ECM spy we have no need of PC or any other device, we can adjust values in the fueling tables, I would start with the street or race ecm standard settings, ride the bike and check the plugs, if you have the money a reputable shop with a brake dyno is money well spent if you are unhappy. | ||
| X1_rider |
I will try the Race ECM eeprom again, maybe with the intake leak fixed it will work better. I'll put off putting my PC back on for now. The dyno tune sounds great as a winter project. Another questions, has anyone tried modifying the cold start enrichment table to make it easier to idle at startup??? (Message edited by x1_rider on July 01, 2010) | ||
| Kalali |
I did spend a bit of time playing around with the CSE table trying to get a stable idle at cold start but to be honest didn't get anywhere...YMMV. | ||
| X1_rider |
Kalali, too bad it didn't work, you really have to hold that throttle partly open for a long time to get it to idle. I wonder why that is. I just compared the values in the CSE tables for the Race ECM program and the Stock ECM program that I saved from my X1 before re-flashing and all the values are exactly the same. It's strange that it doesn't work the same. (Message edited by x1_rider on July 01, 2010) |
