Just how poorly tuned are our factory ECU's? If the 20% gain is due to the Power Commander, the filter, and the silencer, then how much is due to the PC alone?
Not that I want to take anybody's eye's off the prize, but I'm curious about Ace's statement about poorly tuned factory ECU's, which led me to ask:Can anybody comment?
I really don't know how poorly(or not) the stock ECU is tuned. Only that the Power Commander could not make much improvement by itself unless the ECU was poorly tuned.
On a dyno test on my bike the stock ECU with an EFI muffler and K&N filter was pretty well tuned. the mixture was pretty much between 12 and 13:1 thoughout the entire range. It could've been tweaked a little closer to 13:1, but in the the real world it works pretty well!Bare
what brand/make/model of ECU are you using ?
Any idea what the CU will retail for?Scott
