PCM Flash Needed for Oil Cooler + PP Rad on 2024 GT (Non-PP)

I bough the package from Palm Beach Dyno, they emailed me that they could help change the PCM setting to adjust the oil temperature algorithm to be the same as dark horse. It's still shipping, I'll let you know the progress.

Awesome to hear that. Keep us in the loop!

That’s really great news! Let us know how it turns out.

Pardon my ignorance, but I am confused. Does modifying the oil cooler variable within Forscan not assist with this? I wonder what this setting is for if not.

It does not. It's probably for another vehicle.

Funny. I’m in the same boat. Just purchased a base model with. Roush phase 2.
just ordered the oil cooler and DH radiator/ fan.
can’t believe Ford performance dropping the ball.
Maybe Roush will be will to update….

Update on the progress toward a resolution. I have had several conversations with SCT regarding the algorithm issue. SCT responded yesterday indicating their engineers are mapping out the switch parameters within the calibration file and will notify me with updates.

 

[Cool66]

Just a thought but the process may move faster if more people create a ticket or inquiry with HP Tuners and SCT regarding the algorithm update. Both have indicated they are looking at it but if more consumers reach out to them for an answer they may place a higher priority on the resolution.

I wrote both, TY.

MightyMars - Did the PBD tune effect the algorithm?

 

[Cool66]

Hate to ask but could someone forward to me a stock base tune file for a 2024 Mustang GT with PP or DH? It is needed for comparison to Non PP to assist a local tuner in routing the oil temp algorithm. Current belief after in-depth study of the Non-PP file would suggest the oil temp algorithm originates in the BCM and NOT the PCM. Any help would be greatly appreciated. Base file format would need to be in a .hpt format. Happy to share the info as it is developed.

What does the PCM do with the information it is "inferring"? Does it pull timing to protect the engine or go into a "limp mode" ? Mechanically you are getting the cooling benefits, right? Just trying to understand the implications since you are not getting an actual reading. If the PCM doesn't make adjustments, perhaps a stand alone gauge will give you peace of mind?

The algorithm consists of several variables to include inferred engine coolant temp, cylinder head temp (most critical), throttle position, rpm, oil pressure changes, and thermal history. At approx 270 degrees, the PCM will begin to pull timing and notify you with the idiot light on the dash. In the ball park of 280 to 290 the PCM puts the vehicle in full "limp" to protect itself. I am working with a local tuner and an engineer from one of the major tuners to correct the BCM "strategy". Prior to 2024, tuners had the ability to change the "strategy" as it was part of the PCM but all that changed with the Gen7. The strategy is completely separate from tuning in this model and currently none of the major tuners are addressing it because the "strategy" is located in the BCM and NOT the PCM. My guess is a corrected "strategy" will be available hopefully sometime next year. In the meantime, we have adjusted a few of the tuning variables associated with temp to keep it from going into limp mode. I have recently installed a standalone oil temp gauge which indicates the oil temperatures are consistently MUCH cooler for during normal, spirited, and track driving than what the PCM is inferring. Adding the cooler is a very noticeable difference. Hope this provides some insight and explanation.

It doesn't do anything. The auxiliary cooler is just a factor that figures into the algorithm to determine oil temp. Im sure all the limits and settings that determine what the engine does at high oil temps isn't going to change regardless of having an oil cooler.

Great Explanation. Wonder why Ford decided to use "inferred" data rather than actual?

never gonna happen. not from Ford. Just too small of a market to even make a ripple on their radar.
