converter?

[McRat]

hmmm 9:00 pm about the time i thought i would here something again from you. ha crossed the line. by payng full price for a converter that does not work? you call me a con artisit but hmm i recall a conversation of you telling me about takeing used alto clutches out of one trans and puting them in some one elses and selling them as new. and im the bad one yea ok. you constanly try to say nick stole tunes but have no proof you the fact remains i did nothing to you and becuase i did not follow along like a good little sheep and finally got fed up you got all pissy and decided not to take care of a issue. im not the first and know i wont be the last you have done this to. hows twisters truck? did kyle ever get his 57 he paid for? i kept quiet over this for a year becasue of your promises of a fix or replaceing the converter. you have not and new you never would. you told me for year it was my tuening spin ons the best is when you said it was my new motor build. but again here we are one more reply by you that has nothing to do with the issue at hand bad 1058s that dont do what they should. but here continue to try to derail the subject. carry on with your 6pack facts.

Seems you claim that everyone who you've gotten stuff from is a rip-off. PPE, Brayden, Mike L, etc. Yet they all tell a different story.

Is the whole world crooked and Tommy is the only honest man? Well, I can say without a doubt that isn't it.

Give it a rest.

umm where did i say ppe was a ripp off ? or brayden or mike for that matter? this has to do with a converter only nothing else. but yet here we go trying to shine the big ole light on me its ok. the fact remains the converter does not do what its suposed to. and if this converter needed to be tuned via programing that should of been known. i would never of bought it or would many others. but im the bad guy for wanting it fixed or to find a fix okie dokie.

You are the master beta tester of the world's best Duramax Tuna. Ask him to fix the tuning. Shouldn't take him one minute longer than the skip shift xerox'g.

IIRC, that converter works excellent in an LLY.

thats the tune nick supposedly stole? I would think if someone was risking the reputation, it would be over a big deal, not a tcm tune that even a EFI n00b could whip up.

as for the converter, what about everyone else with a LMM having issues?

 

[McRat]

Carry on.

Been trying for 2 years. No luck.
The longer you hold the converter boosted on the line the worse this problem gets. The bigger the turbo the worse it gets. Seems the window in the stator is too big and the pump in the Alli is sucking the fluid out of the converter. This problem has been around for a long time with the gassers and now with the increased power we are seeing in the diesels it has hit us.
Everone just hang in there and see what we come up with. I have talked to Terry at PI and will talk to Ron at SC.( That's right Suncoast the company that some stupid M/F's that don't know anything claim I don't use anymore.)
We will come up with an answer.

thanks Mike. I spoke with Ron a week or so ago, and he called Rob for more info on what he's seen with this converter. He seemed unaware of the issue before that call, so maybe he can figure out a fix. Thing is, the 1054 seems to work fine in this instance and Ron said it should have been the opposite, the 1058 shouldn't have an issue and the 1054 would be even worse, if there was an issue at all.

I have yet to find a single person with a 1058 who can get second gear to lock on a boost 4wd launch behind any Duramax. I have found many who get different converters like the 1054 to lock in second with the same power and weight, even more. If it's working with the LLY guys that's good to know, at least then I may have a market to sell mine to if we can't get a solution. I won't sell it if it won't work unless the guy knows exactly why I'm selling it. I'm going to be patient on this one as I know Mike is looking into it as well as EFI Live, and I can't really afford to swap this out right now anyway.

Thing is, this thing is fine for 99% of the guys, as it's only an issue in this one small area of use. Back on topic, hopefully the op has contacted Mike for a recommendation.

I personally dont like the 1057 with 35's and a big turbo It is good at the track but not so great on the street

theres some more helpfull info from god himself I know you think your the only one who could possably put a tune together. and if it wasent you some one stole it from you. but there are alot of smart people out there other then yourself in the tuneing world. if there was a tuening fix that would of been done along time ago. boy alll the lb7 and llys ive herd have gone to 54s. every single person I know that had a 58 tht went to a 54 or another brand converter the issue went away in every instance. the problem is instead of wanting to come up with a fix your little clan always wants to cover shit up instead of finding a fix.

You're welcome! :hello:

Tuning three different LMM's with twins and same mods is a good test of this issue.

1st truck is a 07.5 Twin Lmm with a 1056 converter and a stage 4 that I installed. Locks perfectly in 2nd gear and was a competitor in the 09 DPC.

2nd truck is a 08 LMM twin heavy truck(8500+)and has a Stage 4 and a 1054 converter. About the same power level. I raced this truck for an evening and it also locked in 2nd gear.

3rd truck is Jody's with a 1058. Same power level and we have tried everything available tuning wise to get it to lock. No go.


There are a couple more examples out there in twin LMM's that I have tested(DTT and ATS) with other findings.

Hopefully no one minds me posting in this section, if so please delete.

I can get mine to lock in second gear if I leave from idle (no boost) and then go wot. That tells me it's not the tuning, it's the slip table that the Allison guy verified is in use, and this converters parameters.

So if I understand this right, when you are in T/H and launch in 1st gear, it will shift into 2nd at 3200 rpm, then the RPM climbs past 3200 and stays there until it goes into 3rd gear. An unlocked converter will normally go 3400-3600 rpm and stay there with a big tune from my experiences.

Is that right?

Not saying I can, but if I can fix it will Tommy fade off into the sunset? I'll give out the tune for free if he does.

from what i have logged the looser converters have too short of a wiundow to lock in secound gear and end up locking right when it hits third , the reason the tighter converters will do it is because of a higher rpm drop and creates a wider window . from my log i show only spending 1.01- 1.204 secounds...... in secound gear , it starts to lock and the has to unlock for the 2-3 shift . i think anything outside of 3rd gear low-mid lock is a bad converter . i see a 400 rpm drop between gears till it locks even a unlocked converter should show a rpm drop

If you can fix it in the tune I will gladly buy it, whatever price you want. I do not think you're going to fix it in the tune though, since the tcm won't command lockup in second due to excess converter slippage. I'm hoping you prove me wrong.

Here is a couple logs that will show the difference. The tcm is commanding 1-2 upshift at 3200 rpms. On the first log I leave at basically idle and roll into the throttle, hitting wot while still in first gear. It shifts real close to 3200 rpms and locks the converter as it should, holding it throughout the run. I then went right back to the starting line and re-did the run (log 2) with the same exact tune and did a boosted launch. You'll see that it goes past 3400 rpms on the 1-2 upshift and won't lock the converter until 4th gear.

I tried lowering the 1-2 shift speeds and rpms way down, but it did not change the lockup on a boosted launch, though it upshifted earlier.

edit: I can't post the logs, but take my word for it................

I only get a 250 rpm drop between gears when it's not locked, so my 1058 is obviously a lot looser than your 1055, hence the issues we're seeing with it. If mine doesn't lock second it never locks third, waits till 4th gear. Leave unboosted and it'll lock second every time. I've got logs back to Jan 08 when I bought it, and Feb 08 when I took the truck to the track for the first time, and the non-lock and 250 rpm drop between gears is exactly the same. So in my case the converter didn't go away, it's always been like this.

would a co-pilot help at all? 1055 is around 300 rpm higher stall than the 1058.

even if it did its a band aid for a problem that should not exist . mike would know best but i wonder if the stator design is flawed on the 1058 ? Hence the poor coupling and slip diff while unlocked !

lets see you fix it first? and two thats not my only issue with mine under wot my converter will not lock at all it will hit 3600rpm untill you let off the trottle some then it will lock . this is like getting on a freeway on ramp or from a dead stop. does not need to be a boosted launch. weather this is realted to the same issue wich it probbaly is. is yet to bee seen. Ive been saying for a year im all for a fix wether it be tuening or replacement. obviousley a tune would be a better easier fix and would be fine if it fixes the issues at hand.

I was having the same issue as Jody, but with a different converter. Mine would rev to 3600+ in first gear with stock shift points, same in second, converter would lock right at the 2-3 shift. First 2 gears were ugly.

Didn't matter if the copilot was in race mode, high setting, low setting, middle setting, off, etc.

I think Subman has a picture of me running 2 copilots even :rofl:

 

[JoshH]

A co-pilot in full race mode will make the converter lock. I have used it in my truck. Without it in full race mode it acts just like what Jody is describing.
