edge comp= PITA

[DAN V]

I removed my second comp box this past sunday. I was having a bad feeling about the way my truck was running. I had to put the go pedal all the way to the floor just to get it to move. After a few seconds it would act like I had just floored it. Then it would be normal driving until the next time i started it again and go through it all over again. My truck would slow down when I came to slightest hill or incline in the road. All of this was happening while the actual box was not in the truck. I still had the sensors from the comp plugged into the truck. I believe that my truck still thinks the comp is still connected!! Just yesterday I removed the edge wiring and unhooked both batteries from the truck and left the stock map sensor unplugged. I hope that this will reset the my ecm and be back to stock setting. I will not be putting edge back on my truck ever again! I hope that none of you out there had/have the same problem as i had.

If you had the wiring harness plugged into the map sensor and did not have the box hooked up that could definately cause problems. Also, having the map sensor unplugged will most definately cause problems. One of the primary things the ecm uses to gauge how much fuel to put into the motor is the map sensor reading and with it either unplugged it will think you are never making any boost and therefore won't put any fuel in. With the harness connected to it the comp box intercepts what your map sensor is sending out and sends a corrected reading to your ecm so that it doesn't set an overboost code and defuel - with the comp box unplugged but the harness there I believe the ecm would also see zero boost.

you don't undeerstand my problem. After i removed the box i could not get the truck to move. All it would do would be 30 mph for at least two minutes then it would kick in. It would not move unless i had the pedal all the way to the floor.

 

[Steve St.Laurent]

I understood that. By having the box removed but the wiring harness still in place (I assume you had it connected to the map sensor and then the factory harness) you had completely disconnected the map sensor from the ECM - therefore it would not let the injection pump put out hardly any fuel. Until the ECM sees boost it won't put out hardly any fuel at all so that it doesn't smoke out the world. The way the performance boxes work is the performance box reads the map sensor to see what the true boost level is and then it sends out a signal to the ecm to fake it out as to what the boost is (it won't let the ECM see more than 18-20 psi). If you have the box disconnected there is no connection at all between your ecm and the map sensor. That could cause exactly that kind of problem. Your ECM needs to get a reading from the map sensor.



Now your saying that you have the wiring harness removed but still haven't plugged in the map sensor - your truck still isn't going to hardly move until that map sensor is hooked up. If you hook that map sensor back up and have the edge harness completely out of the truck and your still having a problem then it's nothing related to the comp box - you have some other problem with your truck which could be quite a few different things. Report back once you have that hooked back up and we may be able to help further.

I was having similar problems with my truck... I thought it might be the comp box too... . Pulled the 0216 code... have you tried to pull the codes from the ECM... . has you CEL come on at all ?

 

[nabowers]

i totally agree with steve. you can not run your truck with the wire harness hooked up and the box not. did your check engine light come on? what is the original problem with the truck? you stated all the problems you were having with the box out of the truck, but what does it do all hooked up?(meaning with the box connected to the harness and harness connected to the map sensor, data plug, pump wire, ground,and fuse box or 12v power source) where do you have it grounded at? stock location on the intake is some times not a good enough spot. edge recommends running ground to the neg. battery cable if you are having problems. i my self went through 2 boxes thinking at one time that edge was junk, but turns out it was the trucks issue and a little bit of mine also. be patient, don't just start unplugging wires and running it down the road. that will never fix a problem, just create them. nathan

I agree with Steve also, sounds like you have a dead pedal could be VP44 going south, or the APPS, i am not saying it's not your box but you need to look at everything, i have run the same comp box for 3 years and never had a problem, but i have heard of some people going through them like water



keep us posted on what you find

Last Night When I Got Home I Disconnected Both Batteries And And The Map Sensor. I Did Not Have The Edge On The Truck Or The Edge Wiring. I Let The Truck Sit For Approx 12 Hours And Reconnected Batteries And The Map Sensor. I Took The Truck For A Test Drive And It Drives Alot Better Without The Edge On The Truck. I Do Know That There Must Have Been Something Wrong With The Edge Because It Did Not Bog Down At All. I Don't Think Edge Will Be Going Back In My Truck Any Time Soon.

 

[GEdwards]

I would plug it back in with everything hooked up and see if it does it again.



If it does. Send it back. If it doesn't, then it was from not having the sensors/box plugged in, or the VP is dieing.

 

[PC12Driver]

The ECM doesn't "learn" anything from the Comp, so unplugging the batteries for 12 hours wouldn't have an effect on anything. It would only be coincidence if you noticed a change.



There are thousands of Edge Comps out there that work just fine. If you're having problems, then there is something wrong with your particular box, your truck, or you don't have the Comp installed properly (bad connections at power/ground, dirty connectors).

DAN V,



10 to 1 your VP is on it's last legs.

Mark @ DPPI

I agree

 

[DAN V]

my truck is running fine with the vp44 i have good fuel pressure steady at 12 psi running down the road. doesn't drop below 8 or 9 when i floor it. i do not hav ethe edge on. i am back to stock setting. The only thing that is wrong is that my CEL IS STILL ON THE DASH.

 

[elandon1201]

I did too but it was an electronics failure that took mine out not a faulty lift pump I forget the code but it was could not communicate with ECM or something like that. And mine ran fine except when you floored it every once in a while it studdered then let off the throttle back on and she took off.

 

[24V-DSL]

Besides the CEL, have you checked for codes?

 

[OL RATLR]

I agree

Third vote for VP44.

 

[PC12Driver]

The CEL will stay on for about 20-30 power cycles IF the problem has been rectified. Cycle the key on-off-on-off-on (that's on three times) and the codes will display in the odometer.

 

[Devan Manis]

if your not gonna put the edge back on your truck, i'll take it off your hands.

 

[DAN V]

i checked for codes tonight. i got the following: 0237 0216 and 1693. I read in the manual and they have to do with the fuel pressure and the map sensor. The last time this happened to me with the edge i got the same codes and after a few days the CEL on the dash went out. and then i went on my merry way.

237 is map and 216 is VP pump death code.
