just put in thundermax auto tune for 08 flhx. to the best of my knowledge all updates and firmware are updated and installed correctly. base settings (maps) current and installed correctly. 96ci no internal eng work(i.e. cams heads or injectors) heavy breather air cleaner and vance and hines hi output pro-pipe. have ridden the bike 4 times for at least 60 miles. stopped to get gas last sunday 100 feet from fuel pump bike stalled and wont restart. earlier in the day on freeway felt like it was running out of fuel< but messed with throttle and prob went away....not sure if related due to throttle grip loose from shitty harley nonglue grip. bike initially would crank over and fire yet die right back out, now no fire. exhaust was extremely hot on freeway, but told common for this exhaust. checking codes i get 2107 internal ecm error (2 instances) cleared tried cranking again and reappeared. plugs dry and new yet cannot check compression. check for spark with inline spark checkers....no spark. ANY IDEAS???

 

i would put the stock ecm bac in and see if it starts and work from that point on

 

First of all you are FBW so there is no glue on the grip on the throttle side so it can twist. Second when you installed the Tmax did you initialize the system like the directiosn said. Also check to make sure you have the O2 sensors in the right spot. Shoot a call to them, they will do you right. Hell I hooked mine up and flipped out because it wouldn't start and it was the battery being weak from all the computer playing with it with the ignition on. Call them up and they will get you started.
