Default Just got my Accessport... but I have a dealer appointment Wednesday for a CEL.

I made an appointment to get a CEL checked out at the dealer and now I got my Accessport. Obviously while searching for the CEL they will detect ECU tampering if I install it, right?

What can I do. Will unmarrying it guarantee they won't detect it. I really don't want to wait till after Wednesday to try it out. And if the CEL is a real problem then I'll have to schedule something else to get it fixed meaning thats more waiting time. What do you think I should do?

Your AP can read your CEL. If you unmarry your AP, the dealer should not be able to detect it. If your CEL is something that doesn't need repaired like Cat ineffeciency, I would cancel the appointment. Some auto parts will do a CEL scan and reset for free.

Yeah, just check the code yourself. The AP can check the code and there is a list in the owners manual of what the codes mean. If you unmarry it the dealer isn't going to know that you have installed it.

If your dealer doesn't do a check sum on the ECU and if they don't actually datalog with their OBD2 monito, they cannot detect a reflash. They have to actively look for the reflash to sniff it out. This has been confirmed by a member that works at a dealership service center. If you can't get the CEL read for free, why not just wait until after the appointment. Oh yeah, Trey Cobb says the AP cannot read historic CELs, meaning if you shut off the car before hooking up your AP to read the code, the AP won't see it. I've confirmed this myself with a p0420 that the AP couldn't read,but my pocketlogger read and cleared with no trouble.

Do the dealers look for reflashes regularly?

Well this is a weird CEL I keep getting. It comes on and stays on for a few trips then it turns off. I'll wait a few days and it will come back again and do it all over agan. It goes through this process maybe in the same tank of gas. It's on now so but you're saying that the AP won't read it?

We've been through this before. I work at a dealer: there currently isn't a way to detect that an ECU has been reflashed by the AP if it has been reflashed back to the stock map. I don't just mean selecting the stock map from the map selector, but literally reflashed to the stock map.

If I were you I would just wait. I'm not sure but I think reflahing now will clear out any history stored in your ECU. I'd hate to show up at the dealer and they can't read anything even though you sweared the light came on. I'd also be worried that they may have to send it back to get a factory reflash to fix a problem.

AP stg1 is not really that big of a deal. I have it on a 03 and its nice. Power is smoother and easier to drive but it didn't give me the big "WOW" feeling I was expecting after waiting a year to get it.

like they said, install the thing and read the damn code, you may not even need to go to the dealer and waste half of a day. What he was saying was that if the cel comes on, check it with the ap BEFORE you shut the car off. I checked and cleared a egt from mine, it took 20 seconds. If you can't read it, or if it goes away, and you go to the dealer, flash back to the stock map, that's all.

I haven't found this "Historic" code thing to be true at all... Just last night, my friend in an 04 WRX popped a P0420 on the way to a friend's house. When I got there (in my 02), he had his car turned off and asked me to pull the code with my AP. I plugged it in and pulled it, no problem. Then I reset his ECU thru the menu... no more code.

That hasn't been my experience at all. I had to use my Pocketlogger to clear 0420 codes that my AP couldn't see.

But even if you find the code and then delete it... wouldn't the actual problem still be there? Thats what I never got about AP.

Off topic: When I install the AP and put on 91 Oct map or whatever, can I then remove the accessport from my car and put it in my house or does it always have to actually be plugged in. You'd probably have to keep it there for the anti-theft thing but how about just after you get the 30 HP? I don't like the idea of having my AP just sitting there in my car.

No, you don't have to keep it plugged in, even for the antitheft map. I believe it disables the injectors. You plug it in, flash your ecu, and unplug it. Mine's in my closet.

The AP doesn't magically fix your car (for cel codes). But some cel codes are bogus and mean next to nothing, or are a result of modifying and still mean nothing. So you read the code and delete it. Or read the code and fix the problem of course!

In my experience the AP doesn't read historic codes, meaning a multiple code will show up once then "?????" shows up after that. Also some codes were apparently left off the list. I have absolutley no idea why.

Umm... how would you enable them then if the AP isn't in plugged in? Or do you mean put the anti-theft on, take out the AP and then bring it back when you want to enable it.

thats exactly what you do, it just take's a few seconds to switch maps. when your done switching maps just toss your accessport in the glove box.

LOL. yes, you need the AP to switch back to the regular driving map. Like he said read before you type.
