Did you reflash the tune after the firmware update? While I don't think Ford can change actual tune parameters, by looking around it seems they can include software fixes for random things, besides just improving functionality.
Is there a way without using something like pcmtec or hptuners? I currently don't have access to either but I will pick up your guys product one of these days, seems quite useful
Let us know how this pans out when the ambient temps hit 80. Curious because the tune was good until it got hot.
I did notice the 35 thing on just updating the procal recently and saw it was doing some strategy tune update as well, the files on my procal still look same. so did you then just plug it in to the car and it have some notice pop up? Was the process you took by just returning it back to stock then reflashing or just flashing the latest FP tune on your procal over the existing FP tune in the car?
Yeah, we'll see lol. Usually I'd already hear something in the 60s when the head gets over 210, but nothing yet. For what it's worth i don't expect perfection given i could reproduce the noise on the stock tune, it was just less common.
In my case I was stock when I flashed so it was just convenient timing. But you can just reflash the performance cal at any time if you want to see if anything is different for you.
I installed this kit yesterday and finished downloading the tune and took it for a spin before dinner… verdict: I instantly knew it was worth it as when I drive out of the neighborhood on a cold stat motor; the A10 transmission is jerky and twitchy. I could barly touch the throttle or it would lurch the car. The program smoothed it out over the whole band. For that alone it was worth it. I definitely feel the torqe down low. The sound changed a little deeper (I have the factory valved exhaust). I can definitely feel the power difference and I am very pleased with the results on my short 15 mile drive.
FP Tech support got back to me and confirmed that there were no updates to my calibration file and said it was just service and feature updates to the ProCal device only, no changes have been made to my tune since 2021. they told me not to try to reflash.
Good to know. Did they give specific details on what the ProCal updates did?
If you send in a stock read via PCMTEC we will make sure multitune and Custom OS is available.
Do you guys do legit real Flex Fuel Tunes?
PCMTec aren't tuners, but their software allows for proper activation of Ford's flex logic in the mustang, and the option to add an ethanol sensor and incorporate into it the flex. Both of these are unique to PCMTec.
Mike explained it above concisely. A tuner can use the OEM flex logic via the level of parameter mapping we have in our software OR you can use our custom OS flex fuel logic which can be made as simple or complex as you like. This can also use a real time flex fuel sensor in the fuel line, or be user adjusted via the cruise control buttons.
