ABU-242 to ABU-244 Conversion

Post by Drew22 »

Hi All,

Would any one know the value of the pull-up resistors for the boost pressure sensor on input pin C2? (BA Falcon pcm) I have measured a ABU-244 turbo pcm and its around 4.6k from pin C2 to VREF on pin C30.

I still think I'm missing part of the picture and I haven't got a buggered pcm here to pull part and see whats missing. The turbo pcms are getting a bit too expensive to rip a good one apart :(.

Cheers

I wish I knew the value for you as it's a cool idea & 242's are alot easier to come by, when I get to the workshop on monday I'll have a look what I have!

Ahh awesome mate, be good if you had one kicking about to check out. Might have try a 2k2 (pull-up) and 2k4 (input protection) and see how it goes.

I can feed voltage into the yellow point with the lab ps and its sees boost pressure in the live data. The pcm has been loaded with a xr6t bin. With a 242 basically free to $50 it's a better option than the 244 if it works.
