I recently bought a 97 F350 with a programmer for the 7.3 and ran into an issue with it.
It won't pass my local emissions test because it brings up an error when the inspection people plug into the OBDII port. It just says "error" on their screen.
I took it to a friend at a Ford dealer and said this may be due to the fact that I have this Edge programmer that came installed on the truck. When he checked it on his machine, it stated there were no codes, as in there were no codes to be checked at all.
One thing he also noticed is when you start the engine, the CEL only flashes very briefly then goes out, like it's being shut off by something in the programming.
I plugged the programmer in just now hoping to restore the stock ECU code so the truck will operate as normal but the programmer only offers me 3 settings; Tow, Race, and Extreme, but no option to go to a stock setting.
Is there a way to clear this aftermarket programming so I can pass emissions?
I think I'll try a different e-check station and see what happens. I can talk to my friend about reflashing the PCM like you said too. There definitely was no option to go back to stock, just the 3 modified settings.
Is a '97 diesel truck subject to emissions testing where you are? Are they aware that diesel vehicles of that era are NOT required to be standard OBD-II? Are they willing to pay for the equipment required to communicate with our trucks?
Yeah you can put it on the stock setting. I wonder if the emissions place can't read power stroke like some of the scanners can't. I would put it on the stock setting and leave it there and just use the edge as a scanner.
Ohio E-Check checks gas cars made 96 or newer and diesel trucks 97 and newer. It's also just in the 7 counties surrounding Cleveland which is stupid as hell. But I digress.
I'm going to try another E-Check station tomorrow and see what they say.
Would having a different setting on the tuner stop the OBDII system from allowing codes to go out to a scanner? I think that's what's really messing me up here.
Tell them that the truck is not OBD-II, and if they're insistent on testing '97 diesels, they'll have to test it the way they would any '97 diesel of any other make that doesn't have an OBD-II port.

Getting through it now that you posted the link. I'm really not interested in running any of the tuner's settings, the truck tows my toy hauler just fine. But if I'm reading DIYMechanic's post correctly, I'd be better off getting the computer reflashed by the dealer and just ditching the tuner outright? Fine by me. I'll talk to my friend who works at a dealer about getting that done.

That's what I wound up doing. I told them about the OBDII exemption sticker on the engine and they just took my word for it. They said they could test it on the dyno which is what they do for non OBDII cars. But lucky for me they decided they didn't want to get the equipment out and just passed me. It goes to show how much of a joke the Ohio emissions testing really is since they only do it one one city; the one whose pollution is more likely from the steel plants than cars. It's fine with me, I'll get plates in the morning and be on my way.
