So anyone attempting this swap struggling with O2 readyness, or cruise control, you definietely have something wrong with your tune. I documented my exact settings in https://www.mustang6g.com/forums/threads/cannot-get-my-2018-gt-to-smog-norcal.229432/post-4510730 and was able to pass smog...

For Posterity; everything I changed is: ECM 22520 Gear Shift Hang: Disabled (this might actually work now but it was doing weird shit for me so I turned it off) ECM 40000/40001 Trans Gear Ratios vs Gear A/B Reverse: 2.90 Neutral: 3.24 1st Gear: 2.97 2nd Gear: 2.10 3rd Gear: 1.43 4th Gear: 1.00...

yeah, if you don't have the ratios set correctly in the tune then I guess the part that runs the O2 checks doesn't like that its getting mixed signals and won't actually run the test. My main clue was that cruise control wouldn't work - so having it work is a good signal that the emissions will...

Ok so the forscan lite app was invaluable. When I dug through all the things it could read there was a 0.020 pressure test thing that was the last part of the evap test and when I turned the car on it set and the car is now ready for emissions testing. Finally! Thanks for the help guys.

So for EVAP, I am getting conflicting info waiting at least 6 hours between cycles should have about 3/4 tank start car, wait 15 seconds as soon as possible find a highway drive at a constant 65mph in 6th gear for at least 10 minutes engine braking to slow down to about 35mph wait 3 minutes? do...

After getting the ratios correct and cruise working, I was able to get the o2 to evaluate Of course evap won’t lol. But that was ok before so I think I just need to drive it more now.

So, as I mentioned and I guess I should have stressed, I did do a Tremec swap in this, which included a bowler harness to make the Magnum XL send the correct signals. So when I said "there's no tune" I should apologize as while I didn't "get it tuned" I did have to use HP tuners to adjust the...

OK clearly I had some wonky values, I re-read @Ruiner46 's instructions and reapplied things and now cruise works. The only thing I'm not sure is how the N/V base plays into this. In my current tune it is 38, but when I drive @60mph I get 2760 RPM = 46. I have not changed it to that yet, as...

can anyone with a 2018 Mustang GT PP1 share me the HP Tuners file they have for their car that works for them to a) smog the car - I can't get my car to smog and I am currently blaming the tremec swap - it consistently will make every emissions control read "ready" except for O2 sensors - but...

Whelp, I tried to do as close to the drive cycle as I could, cars whizzing past me at 90mph while I stuck under 50mph, did not set the O2 sensor, everything else went green in OBDLink. I spent like 3 hours driving the thing around and just cannot get it to set the O2 sensors. I double checked...

... yeah ok so I have plugged several ODB2 tools in and all of them say that the O2 sensor is "not ready". Furthermore, the smog station showed me the printout and it clearly says the O2 sensor is "not ready". So ... Anyway, I need to appearely become a ford emissions expert in order to smog my...

Thank you, the only modification is that I've done the MT-82 -> Tremec swap, with the bowler harness to handle the translation of pulses for the driveshaft. So nothing that touches anything emissions related, only changes to the ECU to support the change to the tremec. Thank you, I mean, I'm...

guys, I really appreciate the ... help but I a) did google b) did drive it, like, a lot, and did the full recommended ford emissions reset drive cycle, several times, several permutations (there's several documents out there, all contradictory - I did all of it). I mean, these are just...

Here in ca no O2 sensor can be "not ready" and I am unable to get my car to reset the sensor. I took it to the dealer, and replaced both sensors at the front, and one still doesn't say its ready. So I can't register my car. I replaced the transmission a while back and cruise still doesn't work...

I think I entered an S when I took the screenshot. Can you tell me the name of the sensor I should be looking at? "VSS" is not found but there's about a hundred different "speed" sensors, some are obviously not the right one but the ones related to transmission don't have any data. I am able...

Yeah, it does say 31S, so thats weird. I will correct it to 12. Well at least its easy to change in the Bowler. You connect via bluetooth to it and can change it on the fly. So I'll set it in the transmission settings to 12 and 12 in the bowler and see how that goes. Yup, did that too...

Yup, did that. I think the thing I missed was I did not have HP Tuners in "Advanced mode". So the VSS P/Rev - Trans setting was not visible. This is what it is now. So, the bowler should be set to 12 and this should be set to 12 also? The other thing that in my digging, apparently I might...

Thanks for spending the time over the years to keep posting in this thread Ruiner, you're a shining light for so many of us, lol. I tried setting the ratio values you provided, I have a 2018 GT PP1 that I put the T56 in and plugged in the values you provided, but my cruise is still borked. So I...

yeah I wonder what this costs to do..

That's such a personal choice mate. Personally, I like listening to music, I'd go for the shaker pro, but if I could dig up the extra cash from behind the sofa I'd go for both.
