ECU reset = power loss on high end

does that make sense?

let me explain myself...

since the stock ECU normally "self-teaches" itself depending on air intake and fuel maps, having my mods (downpipe, exhaust, intercooler piping, fmic, etc.) for about a year, would "teach" the ECU to shoot more fuel on the top end and less fuel on the low end....(since 3in. downpipe and exhaust = less back pressure but more high end free flowing exhaust gases)

now that my ECU is reset, it seems that i regained a lot of low-end torque but lost a lot of high end power,

does that make sense? or am i pulling stuff out of my butt? seems to make sense to me... -_- i just hope thats the explanation for my car losing a lot of high end power recently....

how long does it take the stock ECU to relearn?

sorry if that was confusing
 
I think it has something to do with Multiple fuel and timing maps in the ecu.My mirage too had the same problem,but it was till it relearned again (I think).I also heard it was bad to reset it.Not like a honda ecu
