Okay I have two ecu's one is a 38770-mcj-l01 and the other is a 38770-mcj-a01 does anybody know what each part number is for what bike example is one for a 49 state bike or is the other for california bike just wondering cause does one have provisions for an o2 sensor the other dosent i have removed my o2 sensor and have a pc111r usb and it seem if the bike is sluggish below 3k rpm i think it has something to do with harness ecu incompatability idk i believe I have a 49 state harness with no o2 sensor in the bike i swapped out. the bike orginally was a california bike equipped w o2 sensor and i believe I have the original ecu back in it see the shop gave me bike back in pieces and the first thing i did was swap the ecu's and the fi and red light went out hmm any help it seems as if my bike is all back together after a hack shop got ahold of my bike and misdiagnoised my bike they kept saying electrical ie harness and ecu to the tune of over 2500 dollars with parts and labor yeah i got screwed with no lube I am almost at the point of having a really warm fire with it turns out it was a a broken clutch basket bike had a misfire like conditions turns out it was a balance problem lol not really they had my bike for 7 months:mad: so far i have spent almost 3k dollars on this darn thing HELP any

My 954 ECU is 38770-MCJ-A01 and as far as I know it's a 49-state one.
The Cali ECU will throw an error if you don't have the O2 sensor.

my bike is not throwing a code so u dont know if the one ending in l01 is provisioned with o2 is your ecu ending in a01 not equipped with o2

I wish you'd use some punctuation :)
I bought mine believing it to be a 49-state ECU but I've never had it on a bike to know if it throws an O2 error or not.
The error you have/had was for the O2 sensor?
Whichever ECU you installed that killed the error code is obviously the Cali one.

yes the code was an o2 code so i think we figured out by researching a simple part number and using dedutive reasoning

I remember you telling me about that :)
Maybe just skip down a line to start a new sentence?
