re: DPF Problems

So from what I've read, the ECU measures pressure and temp before in and behind the DPF. Seems to me like you could figure out what the pressure drop across the filter is supposed to be when it's clean and restrict the exhaust just enough between the sensors to tell it what it wants to hear without having to re-program the bastard.

Thought about that for 1 second. Restricting the exhaust to the normal DPF pressure would be just the same as having it on, of course without it going into regen all of the time. It slows down the exhaust going through it because of the filter and trying to find a small enough pipe to make it work would basically do the same thing. Still only decent power and garbage fuel mileage. Someone with more time can do all of that testing for me. ME curriculum is flat out kicking my arse this summer. It probably wouldn't be worth the time invested to n'rig it up considering I have 3-4hrs of homework a night
