Gen5 LTx series

[ringram]

Ross any ideas on what model ECU it is?
I take it, its something totally new?

Or is it an E67 or E38?

Looks like a candidate for a nice cam. Stock spec is 200/207-0.550
Heads look nice.

Howard Tanner posted elsewhere it is an all new ECM, never seen before. Not surprised given it's direct injection.
Sounds like we've still got a while before it hits the streets though. I think we all know this is going to be an awesome engine, I'll be at the Holden dealer putting my name down for one when they hit our shores.

E92 is what the press release says, no idea WTF is actually is (Bosch, Delphi).

Ross is gonna have a heart attack if its Bosch though... (please dont though)

This was posted on another forum. Not sure I trust source. I think he tries hard to make himself seem important.

Any ways

Gm has dramatically changed the security acess, iirc 512bit keys and a completely different algorythm, think cray super computer to reverse engineer.

and the entire method for how the do fueling and ignition timming, its just so different. IIRC allot of the calibration is a mathmatical model.

not easily adjusted. _

512bit security algorythm, not happening. Plus they seed key pair will no longer be generated, they are stored in the GM mainframe. Or so I hear. Each ECU has its own seed and key, and its tied to each vin.

Its going to be all after market ECU's for these vehicles, or nothing.

Ok, so whoever is posting all this stuff, how do they know 100% for sure, do they work at GM development, at Delphi? I call BS (but, willing to be proven wrong).

So, just on he's points:
512bit key, maybe, it's conceivable.
E39 & E78 is very much mathematical model based, so probably nothing new there.
Anyway, if GM have locked these down far enough that after market tuning (and therefore parts) can't happen, watch sales plummet in 2014.

He does not work for GM. He has "moles" giving him information. Claims to have insider info on japanese brands also.

I dont take him to serious. I have read his posts on other subjects such as machining and metallurgy. Which is my back round. He is out in left field to put it nicley.

More awesomeness.

I know, I've seen the calibration software its called "inca" and glanced at the code snipets. If you have a few hundred hours to work out the TQ modeling for the throttle input, you might be able to clean up fueling and spark.

Pay attention to what I just wrote there very carefully.

E39 runs the sidi v6 seems odd to throw a new ecu at it, but then gm did give us the e40

I agree, the E39 is capable of running a V8 too. It probably comes down to supplier costs per ECM, in the end the hardware doesn't matter, it's the code inside running that makes or breaks the deal for tuning.

[JOHNBOY]

I am hoping it is E39 or close to it.
Looking forward to hopefully getting the chance to work on the new Gen5 LT1.

It sounds like the ECM will be nearly hack proof, infinitely more complex with a secondary OS and well above where the current ECM's are at. Here is a snippet: The secondary OS within the self contained ECM will overwrite any changes if compromised. And it will NOT but just in case it will. Upon over writing any tuning/tampering... the HIGH PRESSURE SOLENOID will close allow statistic pressure to build to allow for starting and normal OEM spec performance.

Check out the posts from Big Gunz in this thread on tech. Hs states he is Bigg Gunz someone within GM Advanced Combustion Engineering. Could just be a troll with no credible info, but his posts are still interesting to read.
