Has nothing to do with any type of "electrical aspect" of it whatsoever,.. - It is a software problem in the ECM with regards to the actuators AND with the fuel shutoff solenoid sometimes. and always has been!!!

Becuase the ECM has software problems with regards to actuators, failing them, derates that refuse to go away / get stuck in the ram memory, sometimes even after they are working again, and other problems. MANY TIMES IT WILL NOT EVEN THROW A CODE WHEN IT GETS HUNG UP-- IT SIMPLY REFUSES TO OPERATE THEM CORRECTLY!!!!! -- I already explained it in this post that you should never do this ...

I've watched guys put 5 or 6 actuators on their engines,.. ALL swearing they were bad,.. OR flaky,.. or other problems -- all the while IT IS ONLY THE ECM ACTING UP / USUALLY REFUSING TO FIRE THE REAR BANK PROPERLY BECAUSE SOMEONE WHO REFUSED TO LISTEN OR BELIEVE THAT THERE IS WELL KNOWN ISSUES WITH THIS KEPT UNPLUGGING / SCREWING WITH THEM AND GOT THE ECM HUNG UP WITH THESE PROBLEMS AND NO CODES FOR IT FOR HOURS OR EVEN DAYS AT A TIME SOMETIMES!.

Yeah,,. the same things can happen if there is wiring issues with them too.


** IT IS SIMPLY A SOFTWARE ISSUE !

** IT USUALLY EFFECTS THE REAR BANK TIMING OR METERING OR BOTH THE MOST !

** CAN HAPPEN TO THE FRONT BANK BUT NOT NEARLY AS COMMON!

** CAN CAUSE A SEMI-PERMANENT OR EVEN PERMANENT SILENT DERATE WITH NO CODES OR INDICATIONS THAT IT HAS REDUCED THE AMOUNT OF ALLOWED FUELING TO THE INJECTORS SOMETIMES! - This is actually most common when it does not like the coil resistance of the fuel shutoff solenoid, but there is not enough problem for it to throw a code yet.

** ECM DOES NOT THROW ANY CODES FOR THESE PROBLEMS OR HUNG-UP FIRING/DERATE STATES ONCE EVERYTHING IS PLUGGED BACK IN! - ITS A SOFTWARE BUG THAT EFFECTS ALL CM871'S FACTORY PROGRAMMING AND DE-MANDATED ALIKE!

** SOMETIMES THE DERATE OR FIRING PROBLEMS GETS HUNG UP SO BAD THAT IT IS PERMANENT UNTIL THE ECM IS RE-FLASHED WITH A FACTORY CLEAN INCAL / FIRST-BOOT FILE THAT WILL ALSO WIPE THE RAM-MEMORY OUT PROPERLY! - When it gets hung up like this badly enough, it will not have the correct injection timing or fueling for the rear bank UNTIL THE ECM IS RE-FLASHED/WIPED CLEAN ,.. OR.... it will refuse to let the engine have more than roughly about 250mg/stroke no matter how much power/torque is being requested.
