A question for Craig
Craig,
I've read through the previous threads concerning this update, and I have to say it sounds like it will be an impressive one when you get it out the door. I'm sure you don't want to get into the specifics of the upgrade before it's released, but I do have one question:
One of the current characteristics of the FAST system is that changing MAP sensors (from 2 bar to 3 bar, for example) does not automatically scale the values in the underlying tables. So if I have a motor tuned for a 2 bar sensor, and I want to run more boost and install a 3 bar sensor, I can change the MAP sensor value in the software, but this only changes the values on the MAP axis itself, and does nothing to the actual values in the cells. To change the values in the cells, I have to retune the whole motor
Will the update address this behavior in any way? I like the greater resolution I get by running a 2 bar sensor, but I would like to run more boost (perhaps as much as 20 psi), and that means running a 3 bar sensor, but changing to a 3 bar sensor not only offers less resolution but also means doing a complete retune. While some retuning would be inevitable, it seems that the software should be able to convert the existing data internally, preserving the values for the cells that exist in both situations.
I would appreciate whatever you can tell me about this...and if my understanding of this is wrong, please let me know! I'm going to be visiting the tuner in a few weeks, and this 2 bar/3 bar sensor decision is one of the things I'm still on the fence about.
Thanks,
Jeff
