Is there an interest in the 944/951 land for DIY chip tuning?
Anyone interested if I make a walk-through?
Opinions on what is important, or needed?
Other opinions or constructive criticisms?

Rogue,
Will you be able to controll timing?

Rogue_Ant

Yes. The basics - the three timing and fuel maps, RPM limit and FQS scaling:
Will also include the AIT table, and Baro constant. These will be useful for those wanting to convert to MAF, as both compensations will need to be flattened.

I would be interested in this. I've always been curious how the electronic brains of these cars and others work and how to adjust them if needed.

I like your program layout
Did you write it ?

Rogue_Ant

I used a freeware program called TunerPro. Very commonly used for DIY tuning applications.
I simply wrote the definition file, which allows us to use it with the DME.

I'm interested.

Youd have to burn chips though correct?

JohnKoaWood

Nope, TunerPro will work with an emulator like the Moates Ostrich.. there are others as well...

rh951

i'm interested as well.

how are you displaying the afr's, in the tuning windows. i have that soft ware and have been tinkering with it. im for sure interested.

Rogue_Ant

You can burn chips, using a burner..
Or use an emulator, the Ostrich to load changes instantly and is re-writable.

Ostrich 2.0

You have to know where the maps are, then using a simple function, convert the hex number to its AFR equivalent...
This is already done in the definition file that I've made.

joeytoad83

so your then able to tune it by the afr you want??

Rogue_Ant

Yes, actual AFR should be close to the maps, assuming stock AFM and properly running vehicle.
