hey
i buying a 2.0 spi this week and im getting a OBDII harness and computer with it. i want to replace my OBDI (on my 95 1.9L escort) to be able to operate the secondary butterflies and better economy in the fuel mixture. what i am asking is, Is the swap OBDI to OBDII a big deal? How much rewiring is involved? and if anyone has done this work before, could they give me any guidance as to how to attack the work. Any help is greatly appreciated. Thanks!

Have you read the "how to sawp a 2.0 in a second gen"?
That would be a waste of time to swap harness/computer, and take a big chance on messing somthing up, you are taking a easy cheap swap and making it way difficoult than it needs to be.
The secondies motor is a ground and a positive, that are more ways to control it than swapping to the 2.0 computer.

my main concern is the fuel mixture, i dont want it to run rich like fast said. i can get the computer and harness easily, i just want to know if making the switch is a huge deal or just a couple hours of work? Thanks

Switching harness is a big job, but as long as your gonna do that tuch work you might as well put in a Zx2.
The great thing about the SPI swap is you can do it in one day for not a whole lot of money.
But when you throw swapping harness in the mix you just doubled the work if not more. And you take a chance of really screwing somthing up.
I dont know were you heard that OBD1 runs richer than OBD2, but that is about as far from truth as you can get. It doesnt matter if its a 1.9 or 2.0, or OBD1 or OBD2, the air fuel mixture need to be the same ratio.
