DIY tuning software?
 

Does anyone know where/if I can find tuning software to modify my tune (2000 Boxster S)?

I understand that there are folks out there that will tune the car... I'm looking for software so I can do it myself.

There are companies like FVD/Brombacher and Softronic who can create a "tune" (re: software file) for you that can be uploaded through the vehicle's OBD port if that's what you mean ?

I've never seen a program you could buy to adjust the stock dme yourself.

Do you have access to a dyno that would allow you to go through the many cycles of adjust the parameters, test, adjust, test, etc that would result in your getting the maximum out of the tune you do yourself. I know of one guy with such a rig who went through probably 50 cycles intermixed with actual road and track driving to get the right tune that gave him max performance and driveability. And then every mod you do it has to be done all over again.


You are down in FL...talk to Pedro at pedrosgarage.com

Nope, thats not what I'm looking for. I'm new to Porsche ownership but in the GM/Ford world (and others) you can buy software that will allow you create your own custom tune... you have access to change tuning parameters like fuel, spark, etc. LS1 Edit, EFI Live, HP Tuners and Tuner Cat are a few that I'm familiar with. This is more ideal than a canned tune if you understand how to tune a car... and you have the flexibility to make changes to the tune each time you modify the car.




Yes, there are several dynos in the area that anyone can rent time at to do tuning. You may be surprised but you don't really need a dyno to tune. You cant beat having a buddy drive the car while you sit and the passenger seat with a laptop. The dyno is great for WOT but even that can be tuned with a fair degree of accuracy w/o it. Back in my chip burning days, before tunercat came along, I was editing binary files burning a few chips and using an accelerometer to create my data... slow process but as fun as it was challenging.

Who is the person you know of, and what was his "rig"?

What are all of these businesses using for software? All proprietary stuff?

+1 to tuning with a buddy. Add a wideband and alot of time and you get a nice running car. Although, for me, it's a never ending project. It's too easy to tinker.

All of the companies selling DME flashes are using proprietary software.

Motec has drive by wire and variocam control capability, so if you want to go $$$ and don't have to worry about OBDII emissions checks, you could go that route.

In the end though, there's not much to be had with just tuning on these engines without other modifications.

I've gotta say, this is kind of surprising. Porsche guys are pretty well known to be DIYers... especially the air cooled guys. I wonder how long before someone notices the lack of competition and brings a DIY tuning product to market... maybe some genius software engineer/boxster owner will crack the code and help us along. Hopefully something will be available before I start getting the urge to mod this car... it always happens.

Wide band! I put one in after I did my 3.4 swap. When I first went to the dyno we found I was running 10:1. Rich as heck. So in went with the aem uego wide band and a a/f controller. Apexi afc select. I was able to dial my car to a safe 12:2 where needed and can now adjust for other mods. I wish I could mess with the timing but that is not an option. I would love for someone to put a wide band on their stock car and send me their numbers. I'm wondering how de tuned our cars are.

jaay - what kind of performance gain did you notice when you leaned out your mix?

did you change maf housing with the swap? 3.4 has larger diameter maf; ecu may have thought it was getting more air than it really was?

Yes I did swap it. It helped a bit but the car still ran rich. Like I said, I want someone to put a wide band on their stock car to see what it runs stock.
