Diy Tuning

[Ralph Wiggum]

If you choose to look at it that way go ahead. Im not going to argue with you. The intent of this thread is for DIY tuners to share their experiences and techniques.

The intent is not to distribute tunes that are the intellectual property of a business, nor is it to bag out tuners for their perceived short comings. If this is the road its going to go down I will be locking it up.

That's a pretty dull way of looking at it. Most things that are anything these days have all had a concept that they are based off. Then businessmen/companies get a hold of the base part, make their own modifications and should have every right to claim rights to it. It's no longer the factory base.

The way these cars are done, you have to take the factory tune anyways dont you to do anything to them? Ford not really giving you the option to go through them (I think there's one here in Perth though who are Authorised Ford Tuners though, Mac Black Performance or something) allows people who specialise in it to earn their way.

Not much different to modifying anything on these cars - we didn't build the cars but we make changes to them. Tuners do the same thing. They didn't develop the tune but they make their own changes/adjustments to them based off values that they understand will have the most positive affects. They get paid for the time the spend doing so, and the tune is theirs.

We wouldn't have bad tuners and good tuners if everyone had the same tunes which is what seperates the tuners apart and those on the "good" side of it would rather keep their stuff in house than post it everywhere.

But yeah as Ralph said, it's about DIY tuning - eg guys who tune from home, not exactly ones who get it from Tuners so should probably keep on topic.

I think for the small percentage of people who want to learn how to the is not going to affect a Business that's does tuning, also you forget that a lot of people who try and tune them self fail and normally the mechanics who fix this will add some extra to cover the stuff they have to sort out this is common!!

You will have issues if u just flash one custom tune and copy into another car it might be okay it might not these are the issues you have to consider, things like if it is not right can u diagnos the issue and rectify it ??? Can you even tell if its not right.

Things can go right and things can go horribly wrong just want people who are considering this to go in with their eyes wide open, gearbox and motor failures are possible if you don't know what your dong.

You can learn alot from other peoples tunes but a good understanding of the PCM algorithms is important and something you can't get from HPT or the calibration as its displayed in the software. Best thing if you have just got HPT is to compare ford calibrations, particuarly the NA and turbo :-)

Intellectual property as far as I can see is a nonsense. The consumer pays for a tune end of story. One doesn't sign anything that prohibits them from sharing or disclosing. Further, this is tricky stuff so most people won't have the inclination to DIY tune. Finally, it could also be an opportunity for tuners to develop, and further their own knowledge base also.

What a can of worms.

I knew this would happen. Can this thread still be revived?

Your post is nonsense, The consumer doesn't pay for the tune, he pays for the increase in performance provided by the tuners knowledge and experience. Im not surprised by your views Impellor, I do wonder if you be so obliging if it was your blood, sweat,tears and invested dollars on display for free.

I doubt it. The mod team was concerned it would head in this direction from the start, and I really can't be arsed with it.

Hey guys, so I've purchased HP Tuners and am going to give tuning a go. I will be attempting to turn a standard BF XR6T tune into something that will run the following: ID1000, intercooler, dump and ~15psi.

I've got an XCAL tune in the car currently that runs this combination fine but I cannot edit the tune with HP tuners so it leaves the only option of doing it again myself as a learning experience. What I plan to do is the following:

1. "return to stock" with XCAL4
2. Start hacking the stock tune on the weekends
3. Save hacked tune
4. Load stock tune
5. Plug XCAL4 back in and load my custom tune so I can drive to work etc.
6. "Return to stock" with xcal4
7. go to step 2 until my HP tuners tune is acceptable and I don't need to or want to keep using the XCAL tune.

Now in terms of where to start I've found this guide:

http://www.hptuners.com/forum/showthread.php?48134-Speed-Density-on-the-BA-BF-Australian-Ford-Turbo-6

and been told to read Paul Yaws injector dynamics write up. Can someone post a link to this article?

The next thing to get my head around is how the fueling is calculated. It seems from looking at some offline files and reading the above thread you get your "MAP per airmass high res" to get your commanded AFR to match your actual AFR so you can then tune the base fuel map.

My understanding is you update your base fuel map (TPS vs rpm) to give the AFR you want at specific RPM, the ECU will then use this map along with the calculation air mass to work out how much fuel is required. This seems quite different to how other ECUs calculate fueling, eg they will have a single map of load (MAF or calculated MAF via a MAP sensor) vs rpm.

Am I totally off the mark? Does the command AFR in the TPS vs RPM base fuel map get used like this?

I will keep reading as this seems very different to how other ECUs that I've tuned work and I want to have a solid understanding before attempting any tuning.

Is there an equivalent writeup for ignition timing and injector sizing? As these will be the next things I need to read.

Another thing as I can't read my SCT tune what should I datalog to get and insight to how it has been tuned currently. Eg can I effectively log all of these parameters to reverse engineer what my current maps might be so I have a good starting factor? What is better for datalogging, SCT livelink or the VCM scanner for HPT?
