What are you wanting to do (concerning a tune)?

I only ask because I've had a couple of guys do L67 swaps in these cars and found out they could NOT use a W-body L67 tune in the Intrigue due to the VATS issue.

The Intrigue used the PASSLOCK type VATS system which was not used by any L67-equipped car until 2004 model year (Impala SS and Monte SS). Loading an earlier W-body L67 tune into your PCM will result in a no-start condition.

But you can't use a 2004 PCM in your car because the A/C request signal gets communicated to the PCM from the HVAC control panel in a different way (in 2004-05 L67 W-body cars) than it does in your Intrigue. I'm also not sure if there will be other inter-vehicle communications issues between modules if you use "too new" of a PCM.

Ryan.. Being that the Bonneville got that setup in 2000 and had the L67,...it probably still wouldn't work because of the difference between bodies and BCM's etc?

2000 Bonneville's got the PassKey3 type VATS system; and no it will not work with the BCM in the Intrigue.
