is it normal to feel a power loss for a while with an ecu reset? put in a spt intake and spt catback ((will be getting a up / down and inlet, hoses, pully and fmic in the mail)) reset the ecu and felt it being fast as hell for a day then she felt like she slowed down a bit... and the gas milage dropped.... is it because it's just learning the new airflow? and will I notice a conciderable gain from new pullys, fmic, up/down ??? and will I have to go through this again?
When you reset your ecu, you are resetting the dynamic advance multiplier. So when that happens timing is pulled and as you drive the dam goes back up. You should have it fully advanced in less than 1/2 mile if you go hold about 3-5 psi for a little run. You don't need to floor it or anything like that, just hold a little boost and it will just right back up. Now, your fuel trims are always adjusting for the difference in air flow, but that will generally will not be something that you feel with the butt dyno. Russ
my butt dyno might also just be used to my car by now... that would have been my other guess ... does feel a bit slow sometimes but then when i kick it down I feel her again....
