LMS Stage 4+ questions

[BigPelo]

So when I go out of town and like to disconnect the battery is all that matters!

Thanks for the help!

Last question. The LMS mycal tuner, is it the one with the touch screen or is that an added feature?

MyCal tuner with touch screen is for 2010-2012 models. They also have a MyCal tuner for 2013+ but is has no touch screen.

This is the MyCal tuner for my 2013 SHO:

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

I should know this, but....Can I just switch from one program to another without going back to stock?

I can with the MYCAL (touch screen) so probably everybody can I would guess.

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.

I am currently running an older stage 3 with no torque management. The newer version of stage 3 has torque management.

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.
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: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.  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.

OK, my new new tunes came in late last night. Dan made the fix, and Stage 4 loaded. drove around the block, everything seems good. Now I have to go do some freeway therapy.

Sounds good man!

Hmmm, not much different than my Stage 3. Honestly, can't tell the difference yet. Will just have to wait for the Mycal to come in.

Like Bruce had siad above too, Imine takes 50-100 miles to really "set" in. 

[Larrylu]

I noticed much more difference going back to 3 (temporarily for octane reasons) after running with 4 for a long time. I think the loss in power and the change in personality was more evident than the gain when I first loaded it up.

[Brucelinc]

What was done to make a stage 4 that could be run on 91 octane - and how much more aggressive can it be than stage 3 without risk of detonation?  There may be a lot less difference between stages 3 and 4 on 91 octane than there is on the 93 (or higher) octane versions.
