Does anybody have any tips for how to tune a 5.7 geniii to pass an IM240 test with a supercharger fitted in Aus. Expensive test here in Aus so would like to get it right first time.

turning off the diagnostics with no error reporting will
make the monitors show ready

IM240 is an actual 4 minute long test over 2km (1.3 miles) where total emissions are tested from hot start & through a drive cycle on rollers.

Limited CV8R: Is this a voluntary or in-voluntary test? Any feedback so far on what can be done tune wise to keep you in the ballpark.

HAve a good weekend!

we used to have that here now they just plug in.
monitors set no active faults = pass life is good

one good tip i have heard for the rollers is run the air pump
(if you have one?)
