Can OBD-I be converted to OBD-II?

[Nick8564]

I have a 95 that is OBD-I and I can not find any tuner that will accept this. Can this be converted to OBD-II by replacing the computer with a 96 or 97?

I was under the impression that they are a CAN system, just with an OBDI plug.
I may be wrong.
Either way, to change the whole system would be a pain.
And 96-97 aren't OBD anyway.

you can replace the pcm yes, but it will only allow some updated funcinality for testing, reading real time data, etc. wasnt aware that you couldnt chip a 95 pcm.......

and he is correct, its not obd just the connector is. its why auto zone scanners shrug their shoulders when connected to our trucks.

Usually the older PCMs can be reflashed to the relatively newer quasi-OBDII programs. My original 1994 BEG8 PCM was reflashed by the dealer to a1996 ALF4 program. It cost about an hour's worth of shop time. If you haven't already done so, check with the folks at DP Tuner to see if the can reflash yours. Cheers!

I hooked my scanner (laptop with scanxl pro and enhanced for bundle) up to a 95 f250 yesterday-I had a total of 4 compatible pids-boost, speed, and a couple other useless ones-lol. I was surprised that it even connected, as I used my obd2 cable and software.

if you're trying to chip it then a TS chip should plug right into the PCM

I think the OP is lookin to use some sort of plug-n-play(Superchip, etc.)

After the reflash on my 94 to ALF4, I ran my EASE scanner software (with Ford Enhanced package) on my laptop with no issues. Can run all KOEO tests (Buzz included) and ran diagnostics while running (CCT, ICP, IPR%, Baro, EOT, etc.). Cheers!
