I'm not sure if HP Tuners is reading my values wrong or what. But I notice certain x-axis scaling is off along with EBP values being slightly higher than what MCC shows. Anyone provide some input on this? This seems to happen on every 6.4 file I open.

Anyone with access to SCT confirm the values and scaling?

Thank you. That clears it right up.
Well I decided to test something out and made the x-axis identical to what was displayed in MCC. Now identical tunes....That fixed all of my drivability issues... It doesnt make any sense to have the axis scaled into the negatives... As the truck will never see that... I think its a scaling issue on HPT's side.

No that's how, Ford set it up its not a issue with HPT.
That screen shot is directly from a SID902 (6.4 PCM) Engineering A2L
Ask a ford calibration engineer on why they set it up that way lol.

Thank you. You are right. I apologize.

The X axis isn't MAP it's actually gauge or boost PSI. Negative is anything under sea-level or 14.7 MAP, or 0 on this smoke map. If it was actually MAP you'd only be using the last 4 columns for 85% of the world and that's a waste of that map. -5.8psi is roughly 12500ish feet in elevation and probably scaled to the highest point you can actually drive to on a paved road. That is why it's scaled negative.

I appreciate it.
Does anyone know the table IDs for the Fuel Deviation Max and min? I’m trying to get support to add those tables but I don’t know the IDs off hand. Mcc doesn’t tell me anything.
