Message	More on that when I actually finish it (likely, never) but I don't want them to affect the ECU signal. Since opamps are high impedance (and assumed 0 input current) they are essentially isolated. I used several set up as a 'voltage follower', essentially it replicates the input signal without affecting the reading. LM741 is a very common op amp, if you get more going on you can buy a chip with multiple in it such as the LM324. Then I use several more to merge and modify the input signals depending on what goal I am trying to accomplish. (Being vague as I intend, hopefully, to market the design) ------------------------------------------------------------------ 1992 300ZX NA 5 Sp KH6 (Dead) 1990 300ZX NA Auto 2+2 732 (Dead) 1991 300ZX TT 5 Sp TH1 (Stock) 1990 300ZX TT 5 Sp KH6 (Stock Turbos) (Est. 400 HP) 1990 300ZX TT 5 Sp 326 (GT600R) (Est. 600 HP) 2004 G35 Sport 6MT (DD) 2008 Honda Civic (DD) 2014 Nissan Murano (DD) 1969 Chevy C10 383/TH350 (Toy) 1969 Chevelle LS1/T56 (Toy)
