no boost?

Since the installation of my mods my truck will loose boost after wot.You can still hear the super charger but the gauge does not move.After a minute or two every thing works fine again.Is there some sort of solenoid that i can adjust or remove or is this a chip problem that can be tuned out?
 
You are experiencing the Abuse Management Program (AMP). When you power brake (brake is actuated and engine is under boost) the ECM may enter the AMP and cause the boost to be dumped.

Solution is to install a boost dump bypass kit --- I know JDM has them, and this will resolve your issue. You can also disconnect the boost solenoid, but this may cause the ECM to generate a code.

Hope this helps.:rolleyes:
 
That sounds like my problem but the brakes are never applied, it has always happened during the first to second shift.Where is this solenoid located so i can unplug it at first to see if my problem goes away.Also what do the aftermarket kits consist of and how much. thanks

Boost-By-Pass Kit

And boy does it work nicely. If you want to roast the tires on boost alone, no problem. It never lets up.
It is AWESOME! I recommend getting one, it's the best $25 dollars I've ever spent.

No dout the boost bypass kit works. The only problem that i have with it was the cost. I dont mean to ruffle any feathers and in the long run $25 is nothing but I felt had when I got the package and saw three small pieces(I'm not giving any secrets away) that I could have purchased for literally less than a dollar from the hardware store. I think w/ the amount of money I spent that day JDM could have thrown that in for free!

I usually do throw it in for free when you purchase a chip from me, but one thing you gotta understand about what you get with the kit is this:

You are not only paying for the parts, and the incredibly detailed instructions, but you are paying for the knowledge and research that it took to figure out how to do this.

If I handed you the bag with the parts in them, would you know what to do with them without the directions???

JJ
heck no LOL
before I got the kit I tried finding it to unplug and couldnt haha that wasnt fun. but after words I got the kit and instructions and kicked myself
 
Unplug the boost solenoid bypass. Cost:$0. Unhook battery for 5 minutes will clear the code. Squeeze top and bottom of clip to release. Here's a pic of it.

but what happens doesnt the code come back?
 
The code is does not show up in any way visible to you unless you have a scanner. The only reason to reset it would be if you were taking it in for service. Mine stays unhooked for months at a time.
 
Hey Katoom, I always see you driving down I-24 with dirt bikes in the back of your truck. Now I'm either driving a black suburban or a big 4x4 GMC with a lift and buisness name all over the side windows. All you have to do is disconect the supercharger bypass vacuum solenoid. If you want me to show you give me a call and I'll meet you at exit 31 one day. or call me 1-800-431-5699
 
If you disconnect the solenoid, your computer will SET and STORE a trouble code.

It sets this code when it sees something it doesnt like, and it will run a default value for the problem sensor/system. The codes you get for this type of system are P0234 "Supercharge overboost condition" and P0243 "Supercharger bypass solenoid circuit failure". These are whats called 2 trip monitors, so it would take 2 times under similar conditions to actually turn on the check engine light, most of the time it just stores the code without turning on the light, but it sometimes will and that has been documented.
Also, disconnecting the battery resets all adaptive strategies and clears what the computer has "learned" about your driving habits, and you might encounter stalling and other driveability issues, and on 01 and 02's, it will take some time for it to "learn" the chip properly..

When the JDM boost bypass kit is installed, you would be hard pressed to know that the boost solenoid has been bypassed and the computer doesnt know any different.

I would rather spend $25 and install the kit rather than run around with my computer thinking something is wrong.

And like I said, I usually throw them in if someone buys a chip from me, so its not like I am trying to make a huge amount of money on something so small. JJ


Who cares if you have to disconnect the battery to remove the code, you have to disconnect the battery to remove a chip! You would be hard pressed to know if the boost solenoid was bypassed if you unplug it! I would rather spend nothing and have my truck run just as good as one that has the bypass kit. If you are not trying to make money list the part #'s so people can make them on their own(waste of money if you could get the parts for $1.00).
 
The kit is a WASTE of MONEY, TIME, and EFFORT but if you want to spend some money purchase it from JJ.
 
If those of you don't want to take the time and money to modify your truck correctly, as in with parts from distributors like JDM who have undoubtfully spent some serious R/D on these things, then don't worry about it. Yes the kit shocked the He// out of me when I got it.
But why are you going to keep flaming someone who is only trying to help, not to mention willing to give something away? Just to make sure that someone doesn't screw there $30k toy up? No matter how rediculous it may seem to you the kit does work and it will not show any codes anywhere in the computer.
Just my .02

So...I have to buy JDM parts to modify my truck correctly? Unplugging the boost solenoid is the quickest cheapest no hassle way to stop the boost cut off. There are no side effects other than setting a code. If you have to take the truck to a dealer all you do is unhook the battery and remove chip and plug in boost solenoid and there is no proof that the plug was ever disconnected.

Now if you install a kit designed to bypass the boost, you have to disconnect the battery, take out the chip, and remove the little vacuum fittings. Yes, the boost bypass kit is a mod, take it off when you go to the dealer.


Yes the kit shocked the He// out of me when I got it.

It should have $25-$30 is entirely too much for that kit.


But why are you going to keep flaming someone who is only trying to help, not to mention willing to give something away?

I never flamed JJ. What is JJ trying to help me do? I could care less if the kit was given to me. The kit is worthless.

Just to make sure that someone doesn't screw there $30k toy up? No matter how rediculous it may seem to you the kit does work and it will not show any codes anywhere in the computer.

You won't screw your toy up with the boost bypass disconnected. I never argued that the kit was ineffective. I just say why spend money when you don't have to. I'm happy to hear the kit won't show any codes in the computer. Disconnect the battery and there will be no codes either.


I don't care how much money you spend on mods or other things. Spend away. There are some mods that don't bring any returns for the money. I believe that this bypass kit is one of them. I love you too!
 
I agree with your entire post easterisland. If someone wants to spend the money, fine. If you don't, unhooking it cause no harm whatsoever. Either way works. Either way has to be reversed when going in for warranty work.
 
rpm outlet has free detailed instructions on howto and what to buy part # included to install in 10 min for about 6 dollars its almost like free boost also it can be eliminated electronicaly by a tuner with the proper software chipmaster revolution etc. I prefer the mechanical way though
