Has anybody bought new GM LSx controller kits ?

And is there any information about tuneability ?

Robin L

Yes a bunch of them out there. If you search you can find a couple of threads. EFI live says they can tune it. HP Tuners has a BETA out that says they can tune it. I burned a VIN in one of mine and now I can tune it with the HP Tuners. I will test the BETA HP Tuners on another PCM this weekend.

I have one in my Mustang/LS2 hybrid and yes you can tune the ECM. Mine came with a E67 ECM that we had to flash with a '06 CTSV file using the GM tool. Then we tuned it with HP Tuners just like it was a CTSV. Pretty simple really.

Najania

It does not have provisions for cruise control i can tell you.

Would you happen to know what the trunk length is (where all the the individual lines converge at the rear of the engine to the PCM)?

Najania

I would say 1meter. Maybe 1½.

40inches at least from the ECM to where the Wires branch out for left and right cylinderbank.

Hello Robin,

Anything new on this ?

Robin L

Hahaha, I just replied to the email notification. Damn I am too busy.

here is what I was trying to send...

The Beta version that I used works just fine. Dyno'd 2 different setups ,
one a NA cam and header stock injectors and another a TVS2300 with 60 pound injectors.

Worked just great!

Robin,

Can you elaborate a little more on this BETA version of HP Tuners. Are you saying the BETA version does not require the PCM to be flashed with a CTSV VIN?

I have the LS7 controller kit on my GTO and would love to be able to tune out my rich WOT condition.

Thanks Robin!!

Good news. Can you tell how the controller is actually tuned ?
Offcourse i need laptop but what else ?

Robin L

E Mail support@hptuners.com. Give them your serial number and they will post a BETA version that will accept the non vin GMPP ECU.

You will need to dowload and install that version.

Good Luck!

Robin
