Just figured out how to make TunerPro calculate RPM! Yay! Updates soon...
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
hahaha. i'm still waiting on my buddy to call back so I can grab the ostrich, otherwise it'll probably have to wait til weds when we're dyno tuning another car.
probably just as well, I don't have a wideband for the 940 yet. thinking about getting one of those 14point7 oem type units.
if you changed all the data on a NA box to the same data on the turbo box, would that make it a turbo computer(not officially but run identically).
Fixed. But I think yes. Mine has been shipped, can't wait!So with the Ostrich loaded and running via laptop you can then shutdown remove the laptop and restart and drive the car? The Ostrich thus retaining the maps etc thus becoming the newly programmed ECU's chip?

shark tuner isn't vastly different from TP. I played with one a couple years ago on a supercharged 928. I wouldn't worry as much about setting a low RPM limit per-se, I would just suggest that one should make small changes unless you're scaling an entire map (for say... e85 or bigger injectors or whatever)
Kenny, can you get hands on SharkTuner executable files? There is some nice things to squeeze from it. I now it relies on the accompanying hardware, but still most parts are left to the software side. If I had it after few nights with IdaPRO more nice things will be revealed.
Another note about main fuel map values - there is conversion too: X-128
Then valid range for a cell becomes [-128 : 127], where 0 is zero correction, all values greater than zero adds fuel, negative subtracts fuel from the calculated value, shown here.
In other words if left as is, (unsigned) 128 would mean that after doing the calculation for the given load and rpm, the calculated value is used as is without correcting it (zero correction). Changing a cell by 1 changes fueling by about 0.2%
Sorry for the crappy explanation, but I hope you get the point.
P.S. For the "C/C++" people the values in the main fuel map cells are of type "char".
Great work beepee! Nice to see all the info/knowledge bundled like this!
Question... Lamda correction, if we turn it off, adjust everything to where we want it(I will still want it to be near stoich for most driving, just not the fun and aggressive stuff), then turn it back on, it's going to want to adjust stuff further, won't it? Is there a map somewhere that gives us control over what it thinks it wants to be seeing?
