Just wanted to post up here after jumping in first on learning to tune my 2007 Mustang GT using SCT Advantage per a suggestion from GlassTop, if anyone is thinking of doing the same, I highly recommend buying through Don Lasota. He got my SCT Software sorted and guided me through the base tune process in a span of a week.

Now I am working through fine tuning drivability to my liking and it’s been a blast. Lots of good pointers too in this forum.

I was also shocked to see how aggressive the timing curve was on some of my tunes from other big 3v tuners.

If anyone has any Qs about the process or my experience, happy to answer them here.

Good for you!

FYI..............I also have in hand a copy of Don LaSota's HPTuners version in book form as well, so I have access to his take\methodology on tuning these 3V's too.........thru using HPTuners VCM Suite software.

It took some getting used to PRP. You really need to be organized with your tune files since you cannot 'read' or 'pull' the tune from the X4. Easy to lose track of which tune is actually in the car. lol

I self tune my '66 with Haltech software. Totally agree with the being organized, it can be super easy to lose track of where you are or what you've done.

I keep a notepad file and put every change in there under the date. I'll even include a little description if things got better or worse depending on what I'm working on at the time. I also title each tune the date that I changed things.

Sometimes you start down a path making a bunch of little changes and it ends up being wrong. This way you can go back and start fresh easier.

Hey Brother Stockish, What did you get from Don and what is done to your car? I have a 07 GT I want to tune
I bought SCT through him, and he has a email .mtf tune package you can buy plus his tuning guide. Recommend all three if you are starting from scratch like me.

You have to be super organized and make small changes, one step at a time. He will walk through his tuning philosophy in your email revisions for the base tune to get you started. He will also make revisions for the first 90 days and the .mtf file lets you compare and see the changes he made as well (plus he will tell you what he changed and why).

I have a folder for each revision with a readme file in notes that state the specific change made for that revision.

It’s not hard, but spend time learning the basics and his guide will help you get that.

There is a spot you can save notes with the tune. Under 'customer info' I think it is. But it only pops up the first time you save file. After that, you have to go there and edit notes. I dont use it...lol

For all those so inclined..................

I recommend those who are going to go w\ SCT Advantage to tune these 3V's, to also get at some point the Calibrated Success Advanced Ford Tuning DVD from Greg Banish (access thru his website Calibrated Success.com) along w\ all 3 of his tuning books (available thru Amazon or thru Greg's web site) so that you get an overall tuning perspective from an actual OEM Calibration Engineer who actually worked for Ford before, during & after this 3V platform's development..........who knows\understands the Spanish Oak ECU OS's code line processing & how Ford used this & the most important reason........why Ford set\programmed this OS the way\manner that they did.

I also have all this in hand myself as well as other helpful materials................

Greg also uses SCT Advantage\Live Link II software suite to do all his Ford tuning (also some of the tuning examples he uses in his books.......some is also thru Greg using HPTuners VCM Suite on GM platforms to teach\show the common teachings that transcends across platforms......) thus should be familiar to those using SCT.

Once 1 gets familiar enough w\ the Ford Spanish Oaks ECU OS's code line processing though, it won't matter whose software interface you're using to identify the OS coding thus the maps & settings being tuned then relate to them thru the tuning software you're familiar with........the layouts will be essentially the same.......only the naming conventions may be different.

This can help you to then determine how you need to evaluate what others are teaching you is actually the way you need to go about it to achieve the results you want out of your 3V.................

It will pay for you as a DIY tuner to get\gain perspective from other tuners as well so don't discount them either..............don't allow complacency to dictate your success as you WILL come up short at some point...........hopefully it doesn't cost you an engine or worse, an accident or your life.

Don't make it a habit of bypassing\disabling safeties in the tune calibrations in order to get something to "work"........learn to tune correctly so it does what you want AND don't trip any operational safeties out of hand in the tune........the safeties are there mainly for component failure protection.......but they also provide some protection from shoddy tuning (the cause of the majority of the Mustang crashing memes you've seen\heard of.......someone bypassed a safety.......the IPC Wheel TQ Error & TQ Intervention safeties are the most bypassed\disabled in Spanish Oaks ECU tunes......these prevent an engine RPM runaway from poor ETC TB calibration tuning for TQ control--the most common mistake--OR a TB TPS sensor\TB actuator\APP--accelerator pedal position--sensor failure that causes the TB to go full open & the ECU has lost control of it).......if they're not disabled or bypassed.

You'd be surprised by how much this is still actually being done in these Spanish Oaks ECU's.........................

1 more thing..............I would highly suggest that you go into the knock sensor retard section ASAP & set very high knock retard settings in the max knock retard timing map........in the range of at least -10* to -12* or more..........until you get a handle on everything then set this to your comfort level.......not where someone else says to. The ECU can protect the engine MUCH better & faster than you can so let it do so until you get up to speed & sure of what you're doing concerning setting\optimizing spark timing as well as cam timing. Not only by doing this helps protect the engine, but the data can also help you in knowing WHERE to set the timing to stay out of knock in the 1st place if you're recording\datalogging the knock sensor activity thus can help speed up the tuning process while keeping the engine protected.

Running out of knock retard timing is 1 of the main reasons why modern engines end up destroying themselves from detonation..........because most folks excessively limit the amount of knock retard timing the ECU is allowed to pull when knock is present......even the OEM's set this tighter than I think is prudent............I'd much rather have the engine drop a bunch of power but still be in good working order than pop a ring land, throw a rod, spin a bearing or lift a head cause you're trying to get a low 1.x sec 60 ft time so I can't have the ECU pulling timing during launch...................much cheaper to find\correct the issue causing the excess knock than having to repair\replace the engine and STILL have to find\correct the issue that caused the excessive knock...........

Remember this............if you do all your tuning correctly it won't matter how much knock retard timing you put in cause the ECU won't need it thus won't use it.........but if it DOES need it, it will BE THERE.

Enjoy & have FUN!

+1 to all of this. I will have to take a look at Greg's resources too.

The first thing I did was check the timing curve was safe and ensure KSs were at stock values to ensure the tune was as safe as possible. After having a few email tunes in the past have detonation while under norming driving conditions, I have always been a lot more cautious and being able to see exactly what safeguards are left in the tune is really comforting.

Also, you 100% need a wideband you want to do any sort of self tuning so make sure you have that prior to starting that journey.

To me the 3v is a great learning platform as its modern enough to have easy datalogging and flashing through SCT, but not nearly as complex to learn as the 5.0.

So this is an alternative to a Lito tune or a canned tune?
If you buy the package through Lasotas website for an editable .mtf based tune, it will essentially be the same as any other remote tuner with logging, with the exception that you can edit and see their changes.

You have to buy and learn SCTs Advantage software…and know the basics of tuning

Well, after 19 revisions (don’t judge lol), I am happy to say the tune is officially dialed. Trims are at 0-2% correction everywhere, WOT AFR is rock solid at 12.8-13 with no knock retard with 30 degrees peak BKT + knock sensors adding 2 degrees at WOT, so still well within safety margin for our hot climate here in Houston.

Following Lasotas and Banishes tuning guides + trial and error, it is running better than ever. Spent most of my time dialing in return to idle, drivability and CFSO.

Happy to share learnings with anyone who is contemplating doing the same on their car.

PRP cannot email tunes, only dealer access can. And strategy is likely different too.

Hey Brother Kyle; is there any difference between doing your vehicle and doing others? Other than maybe email?
The PCM code/strategy will be vehicle specific, but the tuning methodology and software will be the same. Some factory strategies are slightly different, and some remote tuners (example Lito) switch to your car to their preferred strategies that are compatible with your PCM code. I think there is a good post here somewhere that has a list of PCM codes and compatible strategies.

Basically you get the PCM code of your vehicle, and SCT provides you a USB dongle for your specific strategy and SCT serial to unlock the software when you open it.

How much did it cost now? Software, wideband...?
Through LaSota, a SCT PRP license was $419, and I bought one of his base tune files in .mtf format for an additional $200. He does datalogging and readable edits on the .mtf file and provides free revisions for 90 days. I already had an SCT X4, so if you don’t have that, you will also have to buy a handheld tuner.

I bought an AEM X series wideband + Bosch sensor for $185.
