Have you loaded a base map from the TMAX program and followed each column in the program to select the items that are on your bike.

Default 99 electra 88 to 95 to 103

Yes the person that rebuilt the motor programed it all in the ecm and tuner..... had to go with the 95ci settings tho.... which thunder max told him to use.... bike was idling just fine till he started to do the riding part of the break in of the motor..... he did an extra week of doing start ups and shut downs of bike.... he programed it all in then was worried he might of did something wrong so was waiting to hear back from thunder max so did the extra week of starting it u p then shutting it down and throwing a fan on it.... now every once in a while it dies on idle when warmed up

Have you down loaded the program and instructions from Tmax yourself to your PC? That is the best way to make sure of any updates and upgrades to the program. When you plug in the Cable from your PC to the ECM and follow the directions, then you might have a better idea of whats going on. The typical idle is set at 982, and if you click on the monitor tab it will show whats going on with ECM while it i running. There is more posts in the tech section on TMAX.

Is it running the original magneti marelli throttle body or did they switch to a newer delphi throttle body?
