This has been my experience as well. Many of the DFSO parameters don't have any effect. I can either turn it "off" or "on" via speed or RPM limits, but its behavior other than that seems to be a...

Here are the driver files that I'm showing:

SOLVED: I was missing C:\Windows\syswow64\ftd2xx.dll. For whatever reason, it works now after adding this file. Here's the file:...

This isn't an option for tuning my 2003 Cobra, as only the MPVi2 supports it.

I was able to install the drivers, but the I'm still getting the "The User Interface is not Found."

Any ideas? Very...

Just upgraded to a new computer with windows 11, but now my MPVi2 Doesn't connect. Seems to be a driver problem. See the attached screen shot of my device manager.

I've installed the drivers per...

I'll give that a try.

Vortech says "47LB EV14" injectors. I was hoping for a brand/model etc, as I understand injector data is critical for these cars. Here is a photo (albeit very zoomed in) of...

No success, and no real change in behavior. Something I've observed:

1) Even though the idle speed is 690 RPM, it never gets there. It surges between around 740 RPM.

2) The ignition timing is...

Thanks for the tip. It seems like the easy fix is to adjust the scaling down low so that the last breakpoint is 0.25 load rather than 0.10 load so the spark isn't jumping around as load changes...

I'm having a devil of a time taming the idle with my 2018 Mustang GT with a Vortech kit. Car runs very well, except I have a surging idle that I can't seem to make a dent in solving.

Car wil idle...

Noted with thanks. I wasn't sure if I needed to adjust the "math" if it was one cylinder or an average of four or eight. Noted also the way it can pull throttle if it's approaching maximum pulse...

Need help/clarification on logging injector duty cycle in VCM Scanner on a 2018 Mustang GT. The standard layout for 2018 Mustangs has a "guage" and a graph for Injector Duty Cycle, but it doesn't...

Interesting. Thanks for sharing this! My only concern with this approach would be: the ghost cam "ramps in" with ECT. If I change the sensor bias to, say, be 10% leaner at idle, won't that make the...

To clarify: with my cam idle tune, my short term trims are adding about 12% fuel to get the mixture to stoichiometric because (I assume) there is an excess of blow through air. The goal is to stop...

That's a good idea. Not to be lazy, but which setting is that offhand?

Is there a setting or a method to target a different Lambda...at idle? My assumption is that in anything other than "power enrichment" mode, the target lambda is 1.0. Is there a way to target, for...

Thanks for sharing! Just a little tweak to get it to run great on my car: 129918

Works GREAT!

Yeah, I saw that. I have the stock MAF, so I left my calibration alone.

@jadenbender: I LOVE the simplicity of your approach! Looking at the file, to confirm my understanding: You're pointing optimal stability to mapped point 10 under 1000 RPM (38209), raising the load...

Outstanding! Thanks! I'll take a gander and try it out.

All I've been able to glean is 44895 affects spark retard during tip-out during the first couple tenths of a second, and 44895 affects spark retard from 0.5+ seconds after a tip-out event.

Did quite a bit of searching here, and can't seem to find anyone having success creating a "ghost cam tune" on a Gen 3 Coyote. I'd like to try this on my 2018 GT just for grins. Anyone willing to...
