OK, when i got my pfc, the shop sent me the reciept and it says that "sequential enabled", but my turbos are in a parrallel configuration, is this a problem, or is there a way to change this or something, the car runs like ***, it doesnt accelerate, and backfires, and when you shift above 5k it puffs a big cloud of black smoke from the tailpipe when it backfires. thanks

 

Probably means that the sequential mode is activated. It shouldn't affect anything if your running non-sequential twin turbo's. You can disable it in the commander if you want.

Now the question is. Did you just plug it in and start beating on the car? Do you realize it has to be tuned first? If your engine hasn't blown yet, I'd say your lucky.

ALSO, did you cut the 4 wires that are needed when you install a PowerFC?

when i bought the pfc the shop took a list of my mods and then put a map on it based on those, they said that it would be about 90% correct as far as the tuning, and as far as beating on it, no, since i put it on and it has been running all crazy i parked it, and it is sitting in my garage, while i have been trying to sort through the problems. and yes i did the wires, i didnt cut them though i pulled them out and wrapped them in electrical tape really good. Also how do you disable the sequential on the commander. thanks

 

If you have not read the manual, do so! (pages 36 & 37)

 

it just affects the way the sequential turbo solenoids are controlled (charge control, charge relief, precontrol, etc)

I suspect it is just a sloppy local shop tune, they often don't know what they're doing.
