Default computer

Alright so after changing a ton of stuff I borrowed the computer out of my brothers ranger and now mine seems to be running alright. I need to get one of my own and I was wondering what the best is?

Can I gain any fuel mileage in my OBD1 94?

Would using a OBD2 computer do me any good or harm?

Is it possible to use a OBD2 computer (ohv?)


More power and better mileage would be awesome but I do not know the limitations of the OBD1 computer.

Any help is appriciated.

Thanks,

They are not interchangeable. You need one that matches your truck.

is your brothers ranger an identical ranger? if not i would not have tried swapping computers.

OBD1 and 2 are not interchangeable mainly because of the year and model differences in the engines and the rest of the truck. honestly the only difference is OBD2 is easier to read the codes and add tuners (superchips, bully dog....). but stock for stock performance should be about the same

There is a lot more to OBD2 than that. You can't interchange them.

The truck I swapped with is identical. 94 4.0

Is there an aftermarked computer that is better mapped to get more mpg out of my truck?

No. For an OBD1 vehicle, you can buy a replacement CHIP that goes in the computer, not a whole computer. Most of the performance chips for the older OBD1 vehicles are designed for performance, not economy but suppose it might exist.

The newer OBD2 systems are programmable with a "tuner". Much easier, but you can not do that.
