Performance boxes and TPS, MAP sensor failures??

[pwr2tow]

Is there any corrilation between them??



I have been reading alot of posts where people have been replaceing there MAP and TPS sensors and they are useing a engine power enhancement box.



There have also been some useing other boxes that have had sensor problems and was wondering if it is the tapping of the pump wire that is causeing the faulty sensors.



Is there anyone that has had to replace their TPS and MAP sensors that are not useing a engine power enhancement box that taps the pump wire?



I have never had any stumble problem until recently when I installed the comp box and now my truck has lost engine power (HP, not died) twice while traveling down the road and then it recovers within a few seconds.



Hope it is not a problem with the comp box cause I love the way it performs.



Is there anyone that does not use a box that has had to replace their MAP or TPS sensors due to engine stumbleing or looseing engine power for a short period of time.

I have a TST PM3 comp. version and it hiccups every once in a while. Very unnerving. I even tried keeping the setting on "0", but as long as the box is on, the stumble occurs. I now only turn the box on when I'm ready to spank someone, otherwise it functions only as a boost module. I know my connection is good because the pump wire is soldered.

I experience the "hiccup" too, every once in a while with my TST PM3. And the PowerEdge I used to run did it also.

It's merely a defueling occuring, in my opinion. Not a fault of the boxes, but something in the ECM program trying to "correct" for whatever.....

That's what this post is about, to see if the boxes are causeing the ECM problems and then over correcting and some how causeing sensors to fail.



It is too early to tell what is really going on.



We need every ones vote that reads this thread to get correct information and evaluate this poll, even if your not useing any box. The only criteria is that you own a Cummins Ram with the 24 valve engine.



It only takes a few seconds to vote since your here already.

There is a huge difference in the software that different companies use for their fueling boxes. Blue Chip developed the first fueling box and IMHO still leads the industry in it's "smoothing" technology and software. If you get a chance, try

temporary installations of different brand electronic boxes at the rallies. Blue Chip will reflash older boxes with his latest software revisions, maybe the other companies will too. Some of the glitches in electronics have to affect the life of our VP44, turbos etc. and I see no reason to put up with it.

I've replaced my MAP sensor and it didnt help, the box deffinately makes it more noticable but it will still do it just with injectors. The same goes for my buddies 01 HO with big injectors. The TPS looks like the next candidate for replacing.

For better results I'am just bringing this back to the top.



Thanks to everyone who has responded so far.

The VP44 is very delicate when tapping into its wires and so are the sensors. The sensors work on 5 volts and under, when you star tapping into the system the resistance goes up changing the signal to the ECM and it tries to correct it self. The VP44 does not like to be tapped in, this can cause static noise and mess up the signals from th ECM. There is an issue with a hiccups/stumble on some calibrations and can be corrected by re-calibrating the ECM with the latest version.
