2014 Camaro SS LML Build Thread

[kidturbo]

I was just digging for my custom LMM std trans bin, but don't see it on this PC. However I found a link to this other uncommon LMM version which may be of some help. I actually use the 4Lo wire in this version to control RPM and Torque limits based on grounding one pin. IE: Valet Mode, or Lo Gear Mode is how I use in stand alone setups.

LMM (NQG) Tune VS Standard

As most of you know I prefer the E35B over the E35A ECM for stand alone swaps. And I thought I knew it pretty well, until I started looking to assign some normally unused signal lines for other uses. That's when I stumbled onto a pinnout difference between two build version under the same LMM...

I'll keep digging for other LMM copy and the bit map to switch it. If can't find, I know who has it mapped. It's only 1 bit...

Does OS 1268777 accept VSS to the ECM?

The Bin file that you have, you said its just one byte change? Does that then "activate" the VSS input?, clutch pedal?, how about Reverse switch input or trans temp? Then theres the whole question of will it transmit that reverse and temp data over the GMLan. So many things to check out lol

Found that NOG version while researching those normally unused TCCM related circuits. Been a while since was in it, but that version was specifically related to the floor mount shifter transfer cases model. Since there was never was an actaul standard transmission E35B, the rest was just hacked out of a stock file.
I know EFI added options to change the Speedo Input from CAN to VSS on E38 and some others, but not sure if they ever got around to the E35B. I have an E35B setup on the bench with VSS line active. But don't believe it outputs the speed as TCM would.

Was just reading through your old post. Looks like the ecm will read vss but without a custom bin it errors out and doesn’t feed the bcm what it needs for speedo.

Found an old post stating Kory had built a custom manual trans file for LMM maybe I’ll see if he is interested in building a base file.

Dang

Doesn't surprise me

 

[Jakezed22]

Oooh look at that, is it coincidence that P0833 is a clutch pedal code. Or maybe I might actually be doing something here. Who knows, I sure don’t but this stuff is cool.

Making progress

Update: I’ve decided to narrow down my approach, the results I was getting I think were too broad and just too much info.

I’m now focusing on one single common OS since it is used in both auto and manual applications. I’ve used efi to copy over every difference and disable all codes in an attempt to single out the data differences between manual and auto.

Below I have taken the same file with the only difference being the Speedo segment swapped out. (I imagine part of what makes a manual OS a manual OS is in the Speedo segment. And I got a result of only 15 bytes different. Now that I think I can work with. I’ll repeat the process to single out difference between all segments. Then I might want to start trial and error on a E35A ecm and see what segment does what exactly. Afterwards I plan to use the same method to single out the dtc addresses since they won’t be mapped in an auto Lmm file.

I think I’m getting somewhere, definitely learning a lot. It would be interesting to disassemble the code and be able to see the machine process if I make it that far.

Well I’m hitting a brick wall with this. I’ve compared multiple auto vs standard transmission bin files, some same OS some not. And I cannot find any consistency in the differences. Every file has different set of addresses different and different values in the addresses that are shared. I know I’m missing out on a lot of what I need to know to do this. I guess I thought I could find a pattern easier than it is. I’ll keep researching and digging. Kid turbo stated it is only one bit to activate, thought it would be easier to narrow down.

 

[Jakezed22]

After some much needed rest I jumped back on this. Using what kidturbo said that it is only a single byte switch. Researched how to find “switches” in binary files. Here I’ve located what I beleive to be a switch, possible for manual trans. When I flip over to 8-bit it reduces down to a 001-000 in one file and 001-001 in the other file. Far as I can tell it’s the only switch that is different between these files and since one is auto and one manual maybe this is it. I’ll compare some other manual vs auto files to confirm. I think i should be able to realize the pattern of bytes leading up to the switch or possibly it will be in the same address in every file. Feeling good about it. Gonna keep grinding.

I looked for that base file on my main laptops, but it's been 5yrs so must be on the old old PC. Will dig thru that one when I get home later this week. The copies I did find are highly modified, so would be no good for comparison.

Going through a LMM file now and in the same addresses its blank, ill have to check more perhaps some LMM OS have the necessary data and some dont.
