Well i got my new BCS in the mail today and i went outside put er on and started it up. Still only get 2 lbs of boost, to begin with i had a code 26 41 and 56 being QBDM2, Cam sensor, and BCS. Now im getting a code 55 which shows as a ECM problem in there also. Now im a little confused on one part of techinfo a code 56 is a boost control problem, and 55 is the ECM, now on another part of it for the same gen and year it says 55 is a EGR solenoid fault and that 56 is quad driver b and 57 is the boost problem?!?! techinfo is a little confusing on these matters, now i dont know why i dont have boost anymore, cam sensor is in the mail and should be here tomorrow, but what is the proper code for my problems?

UPDATE: I have an extra ECM so i changed that out and i still have 26, 41 and 56 but theres no 55 anymore..??

Anyone have any thoughts? i got the cam sensor today and tomorrow or monday im gonna put it on or try to atleast...

I don't think that the cam and crank sensor would have any effect on boost...but I could be wrong....Has happened many times before......What are the description of the codes that you are recieving out of the ECM? I thought that the only problem that arose out of the crank and cam sensors was no start conditions because those two sensors control the timing of the motor. The ECM u swapped, was that one with a factory chip or did you swap your thero runner chip also? The quad driver B I believe is related to the trans shift solenoids and something else. Get a chiltons or haynes maual and they can tell you how to troubleshoot the EGR valve and solenoid.

The codes are
code 26: Quad driver module "A" Circuit
code 41: Cam sensor circuit loss of signal
code 56: Boost control solenoid or (56 - Quad-Driver " B " Fault ) depends on which tech info

Now someone told me that a broken cam sensor pulls timing and makes the computer dump boost?? Im thinking that since i already have quad "A" that the 56 isnt a boost control problem and is really a quad driver "B"? Well im changing the cam sensor soon as i have some free time, if anyone has some advice about the codes and what i should do let me know

Well i changed the cam sensor but i still have the code so im going to assume that its the magnet or wiring, my dad has the tools but i dont have the time to be messing around so im just going to take it in to the shop and have them deal with it. Also today i rotated tires, finished my box for my CAI (looks like crap), and changed my O2 sensor. Next week is cleaning the TB (where do i get gaskets?)
