Blue-chip pump cover!

[MD500E]

I recently installed a bluebox 4 wire on my 98. 5. Instead of scotchlocking onto the injectorpump wires, they sell a new cover that replaces the stock one. It has two allen screws, one with a point on the end, the other one flat. Once the cover is installed you simply tighten the allen screws and they make contact at precisely the right spot. Piece of cake to install. Best of all, no scotchlock conectors, and no telltale marks on the wires.

WHoa... ..... COOL

I knew someone would defeat the scarred wire eventualy sucks for those of you that have messed them up already. I wonder if they will sell it seperate?? Don't get me wrong I know blue chip makes an AWSOME product but the PE Comp is more up my alley.

Now if they made a smaller version of the FMS premium box without the guages that would rock.

Blue chip sells the cover for 49. 95. I think they will sell it separately. No more screwing with the wires! They even will sell you the #25 tamper proof torx bit to remove the stock cover. When it goes in for warranty simply remove the cover and replace with the stocker.

you might want to read the thread "PE COMP and wire tap" thread before thinking the dealer can be fooled by not nicking the pump wire. Appearently fuel boxes leave a tell-tale sign in the ECM which techs can spot when hooking the truck to the computer. At this point I don't think there is any aftermarket software available to us which can erase the fueling curves, etc. left in the ECM by fueling boxes.

Can't you disconnect the battery for 30 minutes to clear the ECM memory? I know it works on the vehicles that I work on. (Lexus)

I'm not sure if this will work. Read the post by 15W40 in the thread "PE COMP and wire tap". Makes reference the vp44 has a duty cycle monitor and all fuel maps, duty cycles, etc are stored in the ECM until the INSITE software is used to pull it up (not sure if it can be erased). It was said a good tech can spot the non-factor fuel maps, etc. and know a fuel box has been used.



Maybe one of the 24 valve gurus can exand on this. I'm still mechanical and have not made the switch to electronics yet, so my knowledge of all this electronic stuff on the newer engines is limited.

does it or doesn't it???

Well I have read where a guy with step 3 injectors did it and it did make a HUGE difference. However Steve St. did it and said that nothing happen. I don't know what to belive. I do belive that the ECM stores "unreconized" fueling patterns though. I truly think the techs can hook up their computer and the ECM will say... "HEY LOOK HERE!!!"



I like the idea of this cap over the pump though.

Well you guys knew it was only a matter of time...

I received my Blue-Chip VP44 replacement pump cover from Piers of PDR on Monday... (so far, so good). BTW, Piers, thanks for your expedient service.



Well, I couldn't resist... I just had to BOMB the pump cover!



Just had to!



BTW, the "plastic" pump cover appears to be cnc machined from nylon... pretty trick however, nothing's so good it can't be made better.



I redecked the surface that nests against the VP44, filed and sanded all other surfaces, finishing with 400 wet/dry. Several applications with a trick plastic cleaner made that bad boy look like a million!



I wasn't done there!



On to the wiring "harness"!



I decided to replace the provided ring connectors with some trick new ring connectors I found at NAPA... these have integral solder that melts with a heat gun while simultaneously shrinking the protective (thick) heat shrink tubing. After shortening the length of the wires a little, I decided to add single Weatherpack connectors to the other pump wire ends (VP44 solenoid control wire and ground). This also mates to the corresponding Weatherpack connectors of my Edge Comp wiring harness.



PS: Evan, I soldered the Weatherpack terminals to the wires..... would you expect any less?



The results of this BOMB came out pretty trick.





Ok, ok, maybe I'm certifiable but what the heck, it was fun!

<b>John, after all you have done for your RAM we would expect nothing but the best</b>



Where will it end ENJOY!

 

[John]

Who really knows?

Well Bob, it was like most of the BOMB projects I initiate...



I have a dream...



OOPS! that wasn't it



I guess it was, I have a plan!







I guess I just can't stand to go with the status quo.







I really need to get back to working on the Air Bulldog intake components..... again! (thanks to the morons at Line-X)



..... nothing like doing a job twice.

 

[Evan A. Beck]

Sounds good, John.



Well, we all want to know... Does it work???

BINGO!



basicly the ECM reads a disagreement with Throttle position, boost (up to the Boost module clipping voltage if the truck is equiped with a boost module) and RPM with regards to the factory fueling maps after injectors or a fueling box are used on the engine..... there is really no way around this... if the Tech sees this... . then he will start "looking" for things

 

[jjohnson1177]

I installed this when i got my comp box also. Pretty neat, and easy to do.

Yep, everything is stored in the ECM... I have seen it. However, DC techs usually won't find it because they do not have the Cummins hardware/software to probe that deep into the ECM.

dumb question

alright folks, i haven't asked my dumb question for the day. if the 2 screws that pierce the wire inside the cover are different than the original screws in the plate, is that not just as visible as the "pricked wire"? are they covered up at the end of the install, so can't be seen on the outside? oops, 2 questions. and i did promise it (they) were dumb!!

 

[MD500E]

The one screw is flat on the end and it touches a what apears to be a soldered terminal. The other one is pointed and i belive it pierces into the plastic harness plug. It pokes a small hole in the plastic where there is already a small indentation. When you put the stock cover back on the dealer would have to remove the cover to see the little mark and i would be willing to bet they would never notice it wasnt there stock. I am remembering this from several months ago so forgive me if i got anything wrong. hope this helps!

Evan,I have had everything ready to install for several days now however, as I have been working a lot of O/T I haven't had the time to devote to the completion of this project (or any other for that matter).



In a word, soon!



BTW, the Blue-Chip VP44 cover installation is per krussel's post... you remove the Blue-Chip replacement cover, replace the OE VP44 pump cover and there are NO visible marks on the pump wires.



HOWEVER, that is not why I personally decided to purchase my Blue-Chip replacement cover... even though I have an extended warranty left ( ), I know full well I wouldn't have a leg to stand on if I toasted my injection pump. That said, I purchased the cover as I wanted the best adaptation of a major fueling box (as it pertains to the pump wire connection)... I think that I have achieved that.

 

[EricBu12]

Did this to my 4-wire box.

I took 2 micro switches and with wire, soldered them to the terminals for the jumpers so now I can change the %'s on the fly. both on is 15%, yellow on only is 30% green on only is 40% both off is 50%



Pertty neat

Does the Blue-chip pump cover look the same as the stock cover?
