Boost Controllers and You...

[9d2TSi]

It sounds like you're only getting wastegate boost pressure, meaning that you might need to put the pill back into the line, you have a faulty bcs, or a leak. It sounds like your wastegate is controlling boost instead of the bcs.

Also, adding a mbc isn't a good idea.

Especially at lower rpm and load points.

I have a question about this. I intend on purchasing an 03 WRX and since this is the case, how could I reset the ECU so that when I start driving it, the ECU will tailor to me and not stay with the settings of the previous owner?

Thanks

is this the same for 06 model? im wondering cause i know that in a DSM you can safely go to 17 and all i want is to go to 15 right now. also on a side note a guy i know threw a electronic boost controller on his 02 wrx and he never had a problem. well thanks and i hope someone can help me on my decision.

DSM's and Subarus are two totally different animals when it comes to ECU's, simply invest in some engine management if you want to safely increase boost levels over stock. For the money that you'll spend for a good EBC, you can pick up the AccessPORT and handle your business that way.

If you want to reset the ECU, unplug the negative battery terminal and step on the brake pedal for 5 seconds. However, the ECU constantly learns. It didn't learn the previous owner and then stop learning. It will (probably has) learn around your driving as much as possible even without a reset.

if you put a boost controller on that messes with the air ratio, then y dont you put in a better fuel pump.

Well you CAN, but the car's computer is controlling the fuel input, independant of what the fuel pump is supplying (unless something is wrong, of course). If fuel pumps oversupply what the car tells the injectors to put in, the rest just gets dumped back into the tank.
