I've been doing some heavy thinking ever since I got my truck back from getting the sensors in the trans worked on. I talked to the mech. who did it and he said the fluid wasn't burned and there were no metal or brass shavings in the pan. Now, when I had the pump wire hooked up, I would run the comp on 3x3 occasionally and the thing would studder a bit. Now, once I got the truck back, the second I got it back from the dealer, I nailed the gas and the truck kinda shuddered on me. And I know it couldn't have been the trans slipping (also said the bands were nice and tight and clean). So I figure that the shuddering was the fuel pump dying. Got the pump replaced (with another crappy one that is already dying on me >) and the truck has yet to shudder. Now, to my point. When the truck would shudder with the comp on 3x3, I thought it ws the trans. Turned out it wasn't, it was the fuel pump. SOOOOO, if the trans could hold the 80hp setting (roughly), then maybe it could hold the 100hp setting a.k.a. 4x2. What do yall think? I ran it on 4x2 for a sec. one day and there was no shudder. Crazy, stupid, or logical? I figure that this tranny can't be all that crappy. I know the ferds are better trannies, but if they can hold a 100hp chip and tow and not slip, then why can't we at least hold the power?

But, the question is, how long.

 

My stock tranny would not hold anything above level 3 on the dyno. The lockup clutch was butter on level 5.

 

That's what I was thinking Okie. How long? Stake, the time I ran mine in 4x2 I was locked up at 55mph and stayed into it until 80mph. Never once did I feel it slip. I know it's not the hp that kills the tranny, it's the torque. Guess that's why the ferd's can hold it. Not enough torque.

 

The Fords aren't any better.

Keep it above 1800 rpm before you step on it. Mine would always slow at low rpm. I also have 4.10 gears.

 

Oh yeah. I've got the comp without the wire and I've got it set to where it won't start fueling till about 1800 (doesn't mean I haven't thrown it on 1x5 before ) It's just an idea. I get bored easily (probably cause I'm so smart that simple things bore me :) and start thinking about stuff like this.

 

Blue you could most likely get away with it on sub level 1 or 2, but if you go 5x5 all bets are off.

 

You don't have the wire hooked up ? :<br><br>It shouldn't make any changes without the pump wire.

 

From Edge website:

There are two types of levels on the Comp Power Levels, and Sub Levels. The Power Level sets the power increase under full boost that the Comp module will add, regardless of Sub Level setting. The Sub Level settings allow for adjustment of low boost fueling eliminating smoke if larger injectors or turbos are added.

Sub levels 1-3 on the Comp will provide defueling below stock. The defueling mode is entered if three conditions are met: rpm and boost are below a set value, and if stock fueling is being increased beyond a set rate. These conditions are different for each sub level 1-3. Once defuel is entered the rate of fueling increase is limited resulting in the defueling to reduce smoke. Defuel mode is exited once stock fuel equals the fueling from the limited increase, this way the transition is smooth and cannot be felt while driving. Defuel mode is entered the easiest in sub level 1 and has the smallest allowable fuel increase, while sub level 3 defuel mode is not entered as easily and has a larger allowable fuel increase.

Sub Levels 4 and 5 (and EZ jumper settings 1-3) allow adjustment of the additional fueling above stock based on boost level. Sub Level 5 (EZ jumper setting 3) will add the most fuel at low boost, Sub Level 4 corresponds to jumper setting 2 on the EZ. The amount of additional fuel to be added is calculated, the amount actually added after being compared to boost from the total is as shown below:
EZ Jumper setting 1 33% is added at 0 psi boost
100% is added at 20 psi boost

EZ Jumper setting 2 50% is added at 0 psi boost
100% is added at 15 psi boost

EZ Jumper setting 3 67% is added at 0 psi boost
100% is added at 10 psi boost

Fuel may be added at 0 psi boost on all Sub Levels and EZ Jumper settings unless the defuel mode is entered as described above.

Power Level 1 on the Comp is the same as the EZ, on Power Levels 2-5 addition power is added via the wire tap onto the VP44 injection pump. If the pump wire is not attached with a Comp Levels 2-5 can be ran, but the power gain is not any higher than Level 1, the power will come in much earlier in the throttle but overall gain is the same.

Hope this helps

{Hook up the wire and }

 

I've had the wire hooked up before and didn't ever run it above 4(only did that once). But when I blew all the sensors in the tranny (don't ask me how), I took it all off, and then right after that, the Lift pump died, so I haven't had time to hook the pump cover back on. What I had planned on doing, is getting the truck in lockup at about 55mph, setting the comp on 5x1, and easing into it to see if it holds. What yall think? Yall think it could hold it? If it held 3x3 (I'm guessing about 80 xtra horses above stock), then why couldn't it hold 4x2 (about 100 xtra).

 

BB-look at my power..under a stock tranny. i got around to upping my line pressures last week, but other than that i've been running it stock. the fluid is very pink and smells great . i have a converter UNlock switch. i don't use lockup until over 70 and then she flies. sure, i can still slip the lock up clutch, but not as easily as before (before it could turn into butter on a certain steep hill). upping the 24v line pressures-well, you have to use a pressure guage if you want to do that. now i hear that tromping on the throttle with low rpms is bad for the stator.<br><br>like monty says...it's not a matter of &quot;if&quot;, but a matter of &quot;when&quot;.

 

: We were discussing why the FERD trannies seem to be holding up a little better than our trannies.. My conclusion is that the torque curve comes in on the Powerstroke much later after the truck is moving allow less stress to be placed on the tranny. ??? What do yall think

 

well, ford's tranny isn't too much better. the thing is that they canup their line pressures without havnig to take the valve body out. their power curves are also different- being a V8.

 

Watch it on the Fords now I had a 1999 F-350 4x4 Powerstroke with the 4R100. I ran a 120hp chip and a 100hp feed of propane plus breathing mods. That truck was pretty stout in the aspect of being able to scoot. I put 187,000 miles on that transmission. I put the chip and propane on the truck when the truck had 92,xxx. Never had a problem. The torque convertor would slip every now and again but everything from what I could tell through the oil was that it was A-Okay. I liked that ole 4R100. :P

Time to time I'd go nuts on the highway and do run on 4 or 5(never from a dead stop). My tranny was slipping after a few months(bad at the end) when we got my TC out of it, it was gun barrel blue! Even on setting 3. you tranny clock is ticking!<br><br>Glenn
