Hi Eric,

You will not be able to tune your 3.4L V6 (RPO LA1).

You will be able to only scan (you will have to select Dynamic mode).

Regarding BCM not allowing engine to start:

- if you make a false start (when you hit the ign key too briefly, motor cranks without starting...), the BCM enters relearn mode which takes 10 minutes (after which the security light will blink)... you have to do this a total of 3 times (i.e. 30 minutes), and then the BCM will allow the engine to start;

- in future, if the motor does not start on the first hit, turn the ign key all the way to off before trying to hit it again... this will prevent the BCM from entering relearn mode;

I know, it's a real PITA.

We've had plans to do the 3.1, 3.4 & 3.8L for sometime, it's on the cards but not as a priority, one day.

When tuning support is provided, these things would make the car livable:
- disable security no-start,
- reduce coolant fan on/off temps,
- reduce coolant fan AC run-on times,
- allow TCC to lock in 3rd gear.

so i guess support is not availible yet and yes cant wait to make the car more livable any ideas on when thank you

No you cant tune it with efi. I also have the same car, just sold it today actually. HPT supports it, well they support it but its no where close the same as efi live supporting a car. There are alot of tables missing and many things you cant change.
