Pwr commander

[ru486]

I disconnected my power commander then reconnected it and now if i stab it in 2nd occasionally i get a the FI light come on, any1 got any ideas what's goin on with it im carring around the clip to see what code it is but it only does it when i forget the clip ?

Given the limited info given, if it's only doing it at heavy throttle then it sounds like a fuel cell setting in the map is over cycling the injector.
What year is your bike ?

cheers pete

its a 02 with k@n pairs air box valve mod, with akro system it doesnt seem to happen at high revs maybe between 5/7k when i throttle on hard, it feels like it misses then the light comes on its only done 16500kms i only recently got it back from the repairer, i had removed the pwr commander as i was sure the insurance company was going to write it off but they went the other way, the computer doesnt hold a history setting of fault codes that can be accessed ?

And now that youve said that i think i had a fault code come up with that about a year and half ago to do with the injector and i had referanced the manual and it said to check for resistance in the injector with a multimeter or something but then i went away with work for 6 months and forgot about it till now

you reckon its right to ride if i just take it easy or is there a chance of it leaning out or something and i should just discoonect the pwr commander ?

I'd probably disconnect the power commander for now in any case and see if fault goes away ? By doing so at least it will help identify and isolate the problem. It could also simply be the commander gliching ? Because it's a piggy back set up I think from memory if the injectors go to over about 80% duty cycle it will bring the F1 light up. Your also correct in that with Gen 1 you have to read the fault codes before turning ignition off otherwise they are cleared
