Or does someone have a C7 Automatic HPT file I can have a look at?

Hi all,

I am looking to do some tuning on my LSA Swap which has the 6L80/90E platform from a 2013 CTSV.

The original stock vehicle had the following transmission shift positions on the...

Thanks HJ, will grab a tune file in the next few days and post them up.

Hi All,

Having an issue with my auto (LSA/6L90 - 3.54 ratio rear end), had some mods done to engine - higher boost (2.55 upper pulley - block hugger headers, 2.5 inch stainless exhausts, plus...

ok guys,

So we got the thing running really good.

The issue was that some of the codes were not actually turning off until you hovered over the RH side of the DTC and chose what ACTION to take...

Thanks BS, I will come back to you on this when I get a chance.

I don't have a diagram of the transmission TECHM wiring, but there is one spare set of Can wires available on the generic plug I...

Sorry... I meant U0100

Thanks HJ, I will look into this

Hi Blindsquirrel...

Thanks for the reply

Here is what we have (I have added the 120 ohm resistor at the DLC and we are reading 60 ohms across pin 6 and pin 14 on the OBD2)

Hi again...

I also have another issue we are trying to resolve. (Speedo Output)

I am also running the factory harness that we have modified, but I am...

Cheers, I have calibrated IAT1 from a known source (E67 to LS7 MAF table)

Good call...

Hi All,

I have got my LS7 MAF + 100mm tube working well and now need to look at scaling it to the stock tuned 2013 CTSV E67 ECM.
(MAF CARD - GM Part#23256991)

Has anyone got a similar setup...

Hey Dhoag

Any chance of getting a copy/link of the GM GDS for this?

Hey 007 did this work for you?

Thanks

Thanks for that, That's what I thought. I find it strange that HPT does not have this in a user guide?

How did you go with dropping out the TCM?

Hi there,

Is there a "sticky" or manual which shows what each code type actualy means:

Eg

Permanent - No MIL and never goes away
Current ???
Pending???
Old ???

Thanks Jon,

That's good info. Yes we have seriously re-worked the harness so have probably mixed up a pin-out.

Cheers, we will work our way through this.
