im not saying they are, im saying it can be done and will start to be implemented in the very near future. Maybe not on the current model years but later will be. Case in point, look at alllllllllllll the features On-star can do for you .

I was reading some stuff about 5g internet and one of the articles was about just this!
Being able to update vehicles wirelessly... mostly relating to autonomous vehicles but thatís still pretty far off.

I think if implemented, it would be through the OnStar system.

Just needs to have a small non-volatile flash memory for the update to download into. Then when starting the vehicle the update will load up

I wouldn't be surprised if it went something like XM radio. With the activation and deactivation being rebroadcast at intervals for a year or more. This way "unauthorized" tunes will almost never last.

Then there will be a growing number of threads on how to disable the reciever, antenna or update system

The speed limiter used to some how reappear on my LMM. I think GM has been playing with on star updates for quite some time...

All I know is it looks like I got lucky again. First time with an Ď07 LBZ and now with a Ď16 LML.

Well I put 57k miles on a L5P and then I traded it for a Cummins haha.. Well now I'm back in a 16 model lml and I absolutely love it.. (tuned already of course)... I can say that the stock the L5p is powerful and an awesome truck, but if they don't come out with tuning for them soon then I won't ever have one again..

I put on to many miles to have one outside of warranty and I want to keep my trucks more than two years.. Hope that's true about tuning being out soon, I'm anxious to see what they can do lol..

There are some killer deals on 15-16 trucks
Especially ones guys have tuned because dealers wonít accept them as trades

I traded my 17 model ram in on my 16 lml and I had it deleted and tuned.. They acted like it wasn't a big deal, but then a few days later the salesman texted me and asked if I could bring the stock exhaust to them.... But they had already sold my old truck so I dunno just depends on dealer I guess..

I had to return my 15 to stock when I traded it for my 16, it was such a pain I left the 16 stock. I figure it will be worth a ton (bc I left it alone) when the 20 comes out if I decide I want one. This LML might just stay with me. Lol...

I can't verify, since I've never cracked one open, or played with a J-tag tool on these ECU's. But the source is well respected.

I do agree there should be a way to do it, with a little help. The E35, best known to rest of world by another manufacture part# I can't recall, would be a great starting point. It was also used by MB and others. However I once attempted to load a LBZ OS to E35B and LMM to E35A version just for chits and giggles. It actually loads about 90% of the bin, then soft bricks.. So there is obviously some memory mapping differences between those two.

Also ran into similar issues on the GM E38, by installing the wrong year OS file with Tech2. It powers up, runs fine on bench, but shows as locked with no SN or VIN when you try to read/write again. Is a documented memory allocation issue, based on year, using same hardware. So at a min the bootloader is diff.

I've been working with a new stand alone ECU manufacture I met at PRI on unrelated project. I'll find out what's actually involved in driving 50volt injectors, and if they have any interest. Also my friend across the pond said check out this manufacture.

Kidturbo, have you verified that the injectors run at 50 volts? If so, seems to me one may be able to showhorn an LLY or LBZ ecm into it. Don't they run at 48 volts?

It may not work with the rest of the computers, BCM, etc but maybe as a stand alone???

50 volt is just a general range that covers us up to LML. The early FICM was basically a "driver" for powering the Bosch injectors, with control from an ECM without amplified circuits. Kinda a quick and dirty solution, that worked well but has it's down sides. Starting with LBZ, the injector drivers were included in the ECM/PCM.

Then things get really tricky when we hit the LML with high power Piezo injectors. Anyone notice how large that ECM is? Reminds me of an early Mach-1000 amplifier they used in late 90's Mustangs, but with larger heat sink fins. That's because half the ECU is an amplifier to drive these new injectors.

None of gasser stuff has to deal with high voltages or amperage output, and thus the same ECM can operate wide range of engine coil or injector configurations. As where we have to base our hardware design on what injectors it needs to control.
