Just went through an extensive program to make my 2000 X1 run like it should. Found intake air leaks, and the wrong injectors were in it? Go figure... Put back correct cleaned and flow tested injectors, new intake seals, new O2 sensor. TPS and AFV reset. It now runs much better, but still feels a little flat at 3k-4K RPM vs my S1. Definitely pulls harder above 5K RPM. Also, it seems harder to start. Race map, factory (I think) Supertrap, Buell CF Ham Can with K&N. AFV is still learing but is well above 100%. What to do next?

ecm spy and check temp of intake air and cylinder head at rest and in other conditions, not much else presuming that the race maps are good. | ||

Thanks, Oldog, the intake and head temps make "sense" with spy. A little update. Really, it runs very well, MUCH better than when I started. One thing still left to do on the list was/is to pull the supertrapp discs and make sure that the exhaust is free and open. Have found some fiberglass coming out of a drain hole on the bottom of the muffler. The ECU with race map runs much better, but an odd observation is that the ECU with race map is not AFV "self adjusting". Can't figure out why the AFV seems locked at 100%, looks to me that it is not allowed to self adjust. It now seems to be running a little rich, based on spark plug reading. The ECM that came with the bike with who knows what fuel maps had self adjusted to 122%AFV. I took that ECU out, put the other later one in with race map, did TPS reset. Going to pull and verify that the supertrapp is free and clear before doing much else.

You can define the min and max AFV values using ECMSpy. Take a look to make sure its not set at 100% at both ends. | ||

Also, if you are riding in closed loop (less than 3,800 rpm) then the O2 sensor controls the AFV through the ecm. I guess I wasn't aware that the race ecm locks that function w/o ecm input. | ||

" I guess I wasn't aware that the race ecm locks that function w/o ecm input." It doesn't. The Race ECM works the same way as the "regular" ECM - closed loop, open loop, etc. The fuel/timing maps are different along with some other EEPROM specific parameters. | ||

Thanks, Kalali, I noted that what seemed like a check box for auto AFV seemed enabled, but had not found or checked for limits. Will hook the spy back up after I pull those discs (and put a few extra ones in!) |
