LMS Stage 4+ questions

I agree - going from stage 3 to stage 4, even if it has been modified to run 91 octane, should be a very good upgrade for you and well worth it.
By the way, Larry's comments above are exactly what I was told - the only difference between stage 2 and 3 was that 3 had no torque management. I was sent 2 versions of both stage 2 and 3, however - a 91 and a 93 octane version of each. Rick told me that the difference was 2 degrees additional timing advance on the 93 version.

My understanding if I remember both the MyCal and SCT +4 tunes where the same, its the Meth tunes is where they differ. But thats nearly 2 yrs ago when I upgraded to the MyCal so a lot could have changed since then.

I got that from Rick also.
I'm thinking I'd love for LMS put out a list of all the details and history of all the tunes and the variations. It's starting to get confusing and customers should be able to consult something official. If they won't, I suppose we can try to document details ourselves but seems like they are in the best position to provide a definitive reference bible.
I kinda doubt that any of the tuners want to tell anyone too much specific information on the tunes...it seems that it's a pretty competitive field and I would think the less the tuners tell about what that are doing, the less chance for the competition to learn and improve a competitive product...just my take on it. But I think that's why they don't want to be to specific on exactly what they are changing to improve the car.

I sent Chris a link and request to lay it all out for us. Hopefully, he will do that soon. He's probably trying to figure it all out himself. ;D
Mark, I think you may have something there. We don't need the specifics of the tune just a better idea of what they each do.

Haha it looks like a down grade. The other one looks really nice. It will clock 0-60 and a ton more.

Yes...no need to go back to stock when switching from one tune to another. By the way, if you have been running stage 3 and you are going to stage 4, I think you will like the transmission behavior MUCH better with stage 4. You will see the full effect after you drive it awhile and it "learns" the new parameters.
LMS used to call what they used in 2 and in 4+ reduced Torque Management and in 3 ...no Torque Management so maybe that's what they are now using in 3. If so it still shifts firmer than stock.SoCalSHO said:
So that would make 2 and 3 now identical. I wonder if they will just drop 2. I guess that there must be some substantial differences between the new 3 and the 91 octane version of 4 (the old 4+).
We need some reference material/documentation to consult to avoid confusion.
:rant: :rant:One of the bad things about living in a state with low (not 93) octane, is not ever hearing about tunes for 91 octane, such as the stage 4. I would have been running it since its inception had I known. So I contacted LMS to send me updated files for my x3, and order the mycal tuner. I got the new tunes for my x3, was looking forward to trying them Out before the mycal arrived. But my car has a weird setting on the tune, at least the original tune did, where once it is tuned, I put it in drive, it stalls. Happened again with the new tune for my x3. 
figures. :rant: tried reloading it a few times, and now just waiting. But I will probably have the new tuner by then, and then do the trial and error thing again.
