E67 Hybrid Support

Hi All,

We now offer tuning support for GM's Hybrid vehicles from 2007 up using the E67 ECM such as the AURA, TAHOE, MALIBU.

The tuning functions for the Hybrids is reduced compared to the normal gas only engines, however, what is there is the important tables needed for general power upgrades or efficiency. Because these vehicles will never see radical camshafts etc we felt there was no need to invest the engineering time to add in the current 600+ tuning parameters we have on the E67.

Hybrid tuning does not support the modification (or scanning) of the electric drive system, only the gas motor.

You must be running EFILive V7.5.5 or higher for Hybrid support, this can be downloaded from HERE.

Cheers,
Ross

Damn, I was hoping for some support for the Electric side.

IE. Battery State of Charge. Keeping the vehicle in Electric longer....etc...

Hi all. Great forum.

I assume all the Active Fuel Management tweaks are there?

Ditto. I have an 08 Tahoe Hybrid, and you don't have to drive it long to realize that it's way too eager to kick out of electric-only mode, and also way too eager to kick out of V4 into V8. I believe proper corrections would up the mileage significantly. I've been able to increase highway mileage from ~23-24 to ~26-27 by watching the V4/V8 mode indicator and throttling to keep it in V4 as much as possible.

AFM controls are not in the current Hybrid calibrations because so far we only have files sent to us from the 2.4L Hybrid cars. If you have read your Tahoe's ECM & TCM please feel free to Email the files to [email protected] and we will see what can be done for the V8 hybrids.

I'm not actually sure which computer is the decision maker between electric and gas mode, I'd say it's all done on the electric side of things.

BTW, there is an insane number of E67 OS's for the Hybrids out there, so if you do come across one don't be surprised if it's not supported in our current software releases.

Cheers,
Ross

I've got access to an 08 Hybrid Tahoe that I'm sure I could con the owner into playing with let me see what I can do :)

Nothing yet I guess.

I just tried reading it with HPTuners. Nothing. Damn.
I want to be able to tune this thing.

I take it you don't have EFILive then? We will certainly be able to read any Hybrid ECM (as an E67), adding tuning support for what I would assume is going to be an unsupported OS would only take a day or two (a week worst case).
So far though nobody has Emailed us with a Hybrid V8 file.

Yes I do have EFILive, but only FlashScan V1 Commercial .

I considered upgrading, but over $500 for something that may work is something I am not ready to do yet.

I apologize, my friend that has one has been damn near impossible to get ahold of and I dont have ANY to play around with at work. The second I get one I'll read it!

I can appreciate that. I suppose we can put a call out to someone in the San Diego area with a V2 to maybe meet up with you to read the tune out, reading an ECM is free apart from time.

I would be willing if there was someone out here.

Is 12630028 supported?
July 6th, 2009

No, that is not an OS we have seen before.
If we can get the tune file support can be added.

Sorry to bring this one back from the dead after over 10 years.

I've got an 09 Tahoe Hybrid with a 6.0L LFA engine that I just tried to read with my V2 to see what was available for tables. It caused all manner of serial communication faults and DTCs set in multiple modules along with an error from both V7.5 and V8 stating that the ECM was out of range. I selected E67 for the ECM. I think it may be an E67A though? I didn't see that as an option in the list. Obviously, the download failed. I was able to reset everything with my Tech 2 and the vehicle suffered no ill effect. Am I safe to assume that these V8 hybrid ECMs are completely unsupported?

I was mostly looking to see if I could disable AFM / VVT or see if it was possible to swap to a different engine segment to allow me to swap something other than the 6.0L engine in if the engine packs it in due to AFM mechanical issues.

Yeah sorry, dead and buried on the E67A, in fact it never got off the ground.
