I probably know this but just can't think of it right now, but what is an fcd?

just change the 2k to 200k and the 3k to 300k, as long as the ratio stays the same. besides at most you are pulling like 5ma even with the 2k and 3k resistors. I used the 2 and 3 k and it worked like a charm, besides with my ghetto design you do want to alter the map signal to a max of 2.75v. In the end it works fine atleast for my car, if you want to adjust swap the resistors with variable resistors and adjust. Not exactly textbook perfect but works in the real world, besides if people wanna use something like this they are content with not throwing out a CEL, which this thing does perfectly fine. if people are really concerned then you can use 2 inverting op amps, which I have used before and worked like a charm. the 2 opamps with adjustable gain would be more of a textbook solution but then again it is more of a hassle to work with.

Damn toolean, your always tweaking on some new invention. i hope you dont try meth, because you would be up for days working on this stuff. looks interesting.
