Oh nooooeeeeeessssss!!!!!!!!!!!11111111

I'm looking at the external MAP input. The lopass filter has a time constant of 220 ms. Isn't this a little slow? It may cause tip-in hesitation or lean-ness when the turbo is spooling very quickly. A 2 x 30~50 ms (2-pole) filter may be better. That's what I used.

That's for a second map sensor, the conditioning circuit for the main MAP sensor is still on the V3 board.

Ben hacked the Gibson for the super secret schematics.

That's only the MS3X schematics, but it's a start :P

Wow.

Yeah, it's a great start. I've no idea what transpired to make this happen, but I'm grateful for it.

edit: I made sure to drop James a thank-you note. :D


edit2: I stand corrected, James informs me that we have the good people at DIYAutoTune to thank for convincing the powers-that-be to allow the general release of the MS3X schematics.

Thank you all, and here's hoping that we see the processor board eventually follow suit. :bigtu:

...and he didn't even need a Gillroy or Lenny Pembridge nose.

Yep, we'd all discussed it, but it was DIY that made it happen.

The second MAP sensor BTW is mainly for baro, which shouldn't change that fast.

I have to say though that I doubt VERY seriously that the processor board schematics will be made public.
