What do your VE tables look like?

You'll need to patch the PCM code with the lean-cruise addition. GM's Holden subsidiary has been a great source of all the stuff for us in the US.

As seen above there are no ve tables.

I have an ecu that allows instant switching between tunes.

Nice work!!! Keep us informed!!!

Today I drove the 485 loop 69 miles (I know it too short to get am accurate read) my trip meter clicked off 29mpg when I pulled into my drive. That's 9 mpg better than EPA rating. It's a good result for a car that will not be visually altered for milage.

Oh btw the odo rolled over to 256,000 miles on that trip this is the original engine. It's never been apart as far as the records show.
