Posted July 9, 201014 yr I can not find a ecm for a 01 SO 5 speed I have found 3 01 HO ecm's. My question is can you reflash a ho ecm over to a so ecm?
July 9, 201014 yr I can not find a ecm for a 01 SO 5 speed I have found 3 01 HO ecm's. My question is can you reflash a ho ecm over to a so ecm? Would the truck even noticed its a HO ECM? I mean aside from the hp/tq increase, the sensors and plugs are all the same right?
July 9, 201014 yr Author At first I was just like you, but then I considered the JL factor in and it might go to the moon.lol I dont know if the vp and ecm have any communication as far as diff. hp
July 11, 201014 yr Author I was talking this over with someone and he said that either SO or HO may fuel more than the other.
July 11, 201014 yr I am guessing the HO fuels more, as it has more power..I don't know if the compression difference will make a difference or not.
July 11, 201014 yr Author Yea we talked on that also. Best I know it can be reflashed to a so. So maybe it will work.

So maybe it will work.it probably could be reflashed(most can). the question is whom do you know with a bench to do the work? as far as fueling goes the HO produces 10hp/45foot lbs more than the SO. it also has a higher compression and a vp44 designed differently. i personally don't think the ecm fuels much more than SO, or the #'s would be higher:2cents:
