Where is one single dyno showing that this "ecu trick" adds 10-20 hp on an sti? It makes no sence. What we need to see is a bone stock sti, dyno'd, then reset the ecu, dyno again and see what we get. Where is this dyno at? (truth is it loses about 10whp)
Lets see..... start out at 230whp, reset ecu and wow look I gained 20whp!!!!
Maybe thats why my car has yet to run 12's stock
totoherbs - seams to be anti intake and i don't think would ever belive that they can make a difference.
People get in these ruts from reading more than actually doing and then all of a sudden these nice "intakes make no difference" staments start getting made into fact and is very hard to belive once one shows an increase in power.
As for this ecu trick....It does not add power to your car! It only makes it get back to it's max advance multiplier faster then driving it around. It's a trick to get back to the power you had before you reset the ecu, not add 10-20 hp to what you already have, So if the ecu was reset and the intake was put on and dyno'd before the ecu got a chance to get to the max multiplier, then guess what....Your power was from the intake, not the ecu, So reset the ecu, dyno the car, then do the reset trick and dyno the car again, what happens? I'm guessin that you would get more then the inital run cuz the ecu will be relearned at this time and not running off of 8 degrees advance. I'm dumb right? what do I know? Right?

The same things applies to the stock ECU. In stock cars, we've seen ECU resets result in up to 10hp losses which slowly add back in which each successive dyno pull. Again, this special reset just speeds along the process.

I think that pretty much sums up that the K&N intake kit makes power. Still don't belive me? read the whole thread about the reset...
How the ECU trick does not add more power than you have.
So there is really only one way to get the non belivers to see that it makes more power...
1. dyno stock car, after it's been relearned right off the street.
2. reset ecu, dyno car.
3. do the reset trick, dyno again.
4. install intake, reset ecu, dyno car.
5. do the ecu trick with intake on, dyno car.
6. compare results and realize....it's ok to be wrong.
So to say that the power came from the ecu is wrong, when in fact it came from the intake, and guess what, it has more if it got that power on 8 degrees advance. I'm guessing that the 12whp was after the ecu relearned itself but i have no idea cuz I wasn't there the day they dyno'd the car to know exactly what happened.
