Engine/Transmission (1998.5 - 2002) defueling at 85mph

[kaffine krazed]

2001 ETH DEE with TST Powermax 3 adjustable and boost elbow. After install truck wont accelerate past 85mph at full throttle and can't get above 90mph easing into it with the box on it seems to be defueling it will go up to 85mph then slow some the accelerate back up to 85mph. Turn the power level down to 0 and it will go up to 112mph with no problem as it did before the install of the box. There are no other performance mods to the truck. Has anyone experinced this before? Any ideas as to what would cause it to defuel? Saturday I'll be able to hook up a DRB and take it for a test drive if you need sensor readings. Thanks.

This from another member that found a cure...



"Scott, i just talked with Mark before sending this to you. i wanted to see if he

had made any progress. well he told me, they have been so busy with moving he

kinda forgot. but he would get to it today and start to fix the problem.



what i did was, i wired into the cab a switch that i mounted inside the roof of

the ashtray. when i know i am going to go over 85MPH i just open the ashtray and

turn the switch off. once i slow back down or get back into town i just turn it

back on. this way i dont have to rev it so much to take off, other wise it will

stall.





the wire in question is the white wire with a orange stripe, it is in the

harness above the valve cover".



That was from fellow member ToddT, back when he still had a 24 valver and the TST box.



I never cut the wire and tried it, but it seems like a simple cure.

"I never cut the wire and tried it, but it seems like a simple cure. "





UMMMmmm - well yeah, I guess, as long as you never race anyone who can go over 85...



Doesn't seem like a very good "fix" to me...

Well Gary, I can honestly say that I enjoy the power I have while below 85 MPH, if that bothers you, then so be it, it's my truck and my DL, not yours.



This is a simple fix, using the toggle to only disable that feature when racing. If you cut that wire for daily use, you will disable the power take off feature and stall the truck when you dump the clutch with low rpms. If you read my first reply more carefully, you would see that this mod. disables the defueling at 85 MPH. Least that's what I was trying to say.



If you know of a bettter method, please share your vast experiences with us all.

Sorry you took my comment so personally - I simply think that the "need" for a user to provide such a band-aid fix is questionable - If YOU like it, and are satisfied GREAT, and good for you!



"If you know of a bettter method, please share your vast experiences with us all. "



YUP - here's a revolutionary idea for those prospective buyers not wanting to add toggle switches to their "magic boxes"



Buy ANOTHER brand that doesn't NEED a "fix"...





THERE - see how simple that was!

Guess that would sum it all up in your world Gary... someone posts a question on how to stop the defueling and your reply is to buy another box. That's a ton of help, thanks so much for insight, Einstein.



Tell us Gary, how does the Comp. box you have compare to the TST we own in regards to defueling ??? Oh yeah, that's right, you haven't installed the box yet, less than tried it with the VP44 wire tapped. Give me a break. If you don't have anything constructive to add to a post, why not just keep your remarks to yourself. Personally, I'm not amused.

"If you don't have anything constructive to add to a post, why not just keep your remarks to yourself. Personally, I'm not amused. "



Well Scott - just to keep things in perspective *I* don't post here simply to keep YOU amused... Nor do I lose sleep when you AREN'T amused...



ON the other hand, neither do I purposely and NEEDLESSLY attempt to personally attack others simply because their opinion is different than my own - I wish some others could also find the maturity to disagree without having to instantly resort to insult and personal abuse...



My comments on the box in question was related to my own feeling that buyers/users of such devices should NOT have to modify them out in the field to make them work in an acceptable manner - and since many PROSPECTIVE buyers read this stuff, as well as those who already have them, it only makes sense to provide info and alternatives for their consideration, since THAT is one of the valuable purposes of this board - or did you MISS the part in my post above where I specifically indicated a solution to "PROSPECTIVE BUYERS" NOR must *I* have ANY brand of box purchased - or installed, in order to comprehend when one isn't functioning properly!



Perhaps you were too busy composing your nasty little comeback to read it carefully - let alone comprehend it?



THERE - now you have one MORE thing to be UNamused about...

Gary don't expect all of us to rollover and ignore sarcasim, when it's directed our way. You waved the first flag, with your moronic reply encapsulated with . Bottom line is that you had nothing intelligent to add to the request from another member for assistance, so you chose to issue a sarcastic non-reply. Last time I checked, this site was founded on the thought that all of us CTD owners could get together and help each other with different issues. Can't say I've seen much of that from you and your posts, maybe I missed one.



Funny, you have no problem asking alot of 24V questions, sure you wouldn't appreciate a sarcastic reply from memebers that did reply, would you ?



I'm done. Go ahead, get the last jab in.







Poor kaffine krazed is probably reading this horse$hit and wondering what the heck he got himself into .



Kinda sad, wasn't always this way on the TDR.

"Kinda sad, wasn't always this way on the TDR. "





YUP - usually, members can be adult enough to recognize responses addressed to an ISSUE, and then be able to comprehend the difference between a personal attack, and a commentary intended to either add to a discussion, or perhaps disagree with a specific solution - all WITHOUT the juvenile need to resort to over-reacting by immediately attacking those with whom they disagree.



You may disagree with me and my opinions as much as you choose (happens all the time!) - especially helpful if you supply additional FACTS on the issue in question - but immediately resorting to personally attacking ME will get you the same in defensive response from me EVERY TIME!



This thread started with a question about a box displaying the tendency to defuel above 85 mph - you helpfully offered a suggestion/solution that worked satisfactorily for YOU...



I then pointed out a weakness in that "solution", and questuioned why a buyer (NOT you personally!) should be faced with the NEED to pay good money for a product - then have to re-engineer it to make it operate properly - I did this TOTALLY without the need to abuse YOU, or anyone else involved in this thread - I was addressing an ISSUE, NOT a personality! And the "smilies" I attached were NOT aimed at YOU - but at the SITUATION!



THe fact that YOU can't differentiate between an honestly offered and non-personal opinion, and a direct personal attack is YOUR failing - not MINE!



Yeah - this CAN be a better place - if a few of the members can grow to recognize the difference between an honest difference of opinion, and a juvenile, needless personal attack - and THEN respond maturely.



And yeah - *I* am done here as well...



My apologies to those with nothing better to do than follow this BS... :-{}
