Ford Fiesta ST V3 Flash Tune Upgrade – Dizzy Tuning

Jason, to confirm, we can upgrade from your V2 to the new V3 flash tune that has some incremental improvements. Do you happen to have access to a dyno plot overlaying the two?

 

[Jason@dizzytuning]

Yes, correct. If you already have my V1 or V2 Flash Tune, then it is a $40 Upgrade fee.
If you do not have my Flash Tune, then any purchase from 12/30/2025 have been getting the new updated version.
I do have a Virtual Dyno graph in the post above, I am working on getting a car on a real dyno.

Would it be possible to have the mods done to the car indicated? Your other post of the Focus ST tunes has this.

This car has a Cobb intercooler and intake. That's it!

Recent dyno results from a customer on the new Stage 1 Flash Tune.
Only mods are drop in filter and NGK spark plugs.

Your dyno post - the red vs blue on there. I'm assuming that's showing V2 and V3 results?

That's a "Virtual Dyno", which is a tool you can use to uplod street datalogs, and it gives you a very good representation of power from a particualr vehicle.
When used correctly, this can be a great tuning tool for finding power gains and more "area under the curve".

So that graph is showing my v2 Flash Tune vs my v3 Flash Tune.
Same customer, same mods, same stretch of road.

Jason nailed it this time, and I’m really impressed.

I was on the fence whether to spend the $40 to upgrade from V2 to V3, but I decided to go ahead. Just flashed on the new V3 (Stage 2) tune yesterday, and wow I’m glad I did.

The first thing I noticed literally immediately on putting the car in gear, pulling out of the driveway and again when shifting into second is that the off-idle and on-off throttle transition has been improved dramatically in the new V3 tune. Pulling away from a stop, coming off the throttle and up/downshifts now feel buttery smooth, even compared to the V2 tune which was already decent. Power delivery feels linear/progressive in a really good way (I opted for the “regular” pedal mapping, not the “aggressive” one)

Of all the flash tunes I’ve tried on the car (Cobb 1-3, Dizzy V2 Stage 1&2 and Stratified Stage 2), this one is the most pleasant to drive in a “smooth is fast” kind of way. Once the roads dry up again I’ll see if I can get some Cobb logs to compare.

What I wanted to highlight is that to me it would have been well worth the $40 upgrade, even if there was no change in the dyno plot from the V2.
