Looks like a more aggressive throttle mapping

You could but I don't think it's a meaningful to dissect it to within an inch of its life. To me the uncorrected number is more meaningful since I know the car will still perform in less than ideal conditions.

The SAE corrected number is more meaningful for "how close did we get to the hp rating of the turbo?"

Also my logs aren't that clean, once I add more fuel the power might go down anyways.

If it's gounggti be the record would be nice to have to bridge the gap between any older std files with newer sae pulls.

I got my baseline done in sae and will skip std correction, but I am not going for any records either.

Thanks, gonna stick with what I have lol I really don't like it when the throttle is super touchy. Got no problems planting my foot when I want to go fast.

It's not what you think it is like stock turbos, just try it out. It's only a 3 minute flash ;)

So I tell Motiv I want THR added to my tune? Or just explain I want my throttle more touchy? Sorry I have never heard of THR or what it stands for...

Ahh, sorry this is just the different files in the JB4/MHD OTS folder. You can basically send that screen shot and tell them that's what you want lol.

Can you explain to me the exact affect this will have? I'm sorry if I sound so newbish. If it makes commuting better with a single or a better driving experience I'm all for it.

Btw the ACF kit is working flawlessly. Installed it myself. Zero issues. Drove it one day for 9 hours straight and not one issue. Love the sound and acceleration! I should have done it years ago. ST life for the win.

Yessir it will make the car feel better with pedal input, better driving and commuting.

I'm really happy man, you've been following my threads since 2014. I'm glad you went with that kit in the end, ST for life.

What about std correction?

From what I have gathered, the difference between SAE and STD is somewhere in the range of 2.6-4%, depending on the actual weather conditions, with STD correction factor reading higher. STD is correcting you to 60f and denser air pressure whereas SAE is correcting you to 77f and less dense air. SAE also factors in an altitude adjustment (@2000ft).

786.0 SAE * 1.03 = 809.58whp STD

I think it's safe to say that with a STD correction factor applied the pull would be over 800whp.

Aha - no wonder STD makes more on FI cars - that 60f and denser air makes a decent difference. Good info - I knew SAE used 77 but wasn't aware of STD correction.

The below criteria infers a 4% differential between the two correction factors. 2.6%-4% is my "real-world" range I found from comparing hundreds of 128i dynos in a spreadsheet. I also found that once you account for these difference that dynos really don't read all that differently from one another. Mustang dynos use SAE correction and most dynojets are load based these days... Of course, you can still intentionally spoof sensors and what not... or make adjustments to the load cells.

STD:
Air Temperature: 60F
Absolute Pressure: 29.92 inches Hg
Relative Humidity: 0%
SAE:
Air Temperature: 77F
Absolute Pressure: 29.23 inches Hg
Relative Humidity: 0%
