Recommended Posts

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?

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

Yea we talked on that also. Best I know it can be reflashed to a so. 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:
