Strat VXCF7D3 to VXCF9H7

Should I reflash to the latest calibration? When I had my FICM replaced over a year ago they also flashed my ECM to VXCF7D3.

Just wondering if there are any advantages to the newer calibration for those that have got the update? I do know there is some advatages like EOT/ECT monitors and what not.

I guess I'm asking if anyone notices better performance with tunes, better starting, etc..with the later strat. I have heard my current strat is the FICM killer, but seems fine..

Thanks

Everything I've read here shows the VXCF4 strategy to be the best and most friendly with tunes. I think your strategy has the heating which is good for cold areas of the country.

Thanks for the reply! I know what you mean about the VXCF4, thats what my truck had before it got flashed to VXCF7. I don't have any drivablity issues and my tunes are strong, just thought I'd put a feeler out there. It does get cold up here in Wash State, so if my current strat has inductive heat I guess that's a good thing.

Yeah, if that strategy is working I wouldn't mess with it. When I replaced my motor the shop put in a new strategy and I had them replace with the old VXCF4 since we don't get very cold here.

I Have the VXCF9 and it WILL be getting rolled back to VXCF4. Not happy with my MPG loss. As well as it starts cold the same as with the old strat.

Well....I went ahead and had the dealer re-flash me to the latest calibration this am. $55

So far on stock file, engine seems to run smoother and has more pep. Email ID to get some new tunes, hopefully that wont take too long!

New Strat is: VXCF9DA

I like that fact that it should be easier on the FICM, has the vane sweep, and monitors EOT/ECT spread and displays CEL for possible Oil cooler issues.

Yeah the Vane sweep and ECT/EOT delta monitoring is nice, But i have an Insight and monitor through that. Im just really disappointed in my mileage loss. I Will agree that the truck seems to run smoother, its just not as responsive as it used to be, and the turbo seems to spool slower as well IMO.

You may enjoy it though

Do you run stock? or do you run any tunes?
