Bruce2009KR Posted February 23, 2016 Report Share Posted February 23, 2016 My month old '09 GT-500KR went in for an oil change yesterday. I brought the Proper 5w-50 synthetic Motorcraft oil and GT500 filter (also Motorcraft). I wanted the air filter changed and they tried but the new one I had from a ford dealer was just slightly smaller and wouldn't fit. Now, my "engine light" appears in my dash. Any ideas why? They said bring it back but something so simple as an oil change and trying to swap air cleaner and this warning light pops up. Any ideas why?? Thanks folks.

twobjshelbys Posted February 23, 2016 Report Share Posted February 23, 2016 you'll have to check the code. Most auto parts, e.g., Auto Zone, etc, will check the code for free. You need to make sure the dealer didn't reprogram the standard "tune" back into the ECU. I'm pretty sure the KR has a unique version. (Someone will correct me if I'm wrong).

MJN Posted February 24, 2016 Report Share Posted February 24, 2016 Maybe by chance they did not get the filter all back on right. Quote Link to comment Share on other sites More sharing options...

Try disconnecting the positive battery cable for a minute to reboot the computer. Quote Link to comment Share on other sites More sharing options...
twobjshelbys Posted February 24, 2016 Report Share Posted February 24, 2016 (edited) Try disconnecting the positive battery cable for a minute to reboot the computer. Doing so will erase all of the calibrations and require a long drive cycle to reset them. It is best to get the code first. Then note that clearing the code will also reset all system calibrations and require a long drive cycle. If the code is evap related (gas cap leak) the resetting will be a long way to just have it come back. I bought a bluetooth OBDII reader from Amazon.com. It can clear codes and also reports the system readiness indicators needed to pass OBDII emissions testing in CA and NV (and others). It uses a smartphone (the one I have currently only supports Android, but there are others.)

twobjshelbys Posted February 24, 2016 Report Share Posted February 24, 2016 (edited) Some tune boxes (e.g., SCT) tell you the manufacturer code of the tune that is installed and the one that is the factory tune. But let's establish first that the KR came with a ECU configuration different from a base Mustang. I'm pretty sure it did but let's be sure you aren't looking for something that isn't there. ECU == Engine Control Unit (the "computer") Edited February 24, 2016 by twobjshelbys Quote Link to comment Share on other sites More sharing options...
Secondo Posted February 25, 2016 Report Share Posted February 25, 2016 Yes,the KR is programmed with a unique Ford Racing tune that has 40 more HP than the standard GT500. Bring the car to someone that knows Fords, especially GT500's. It's a unique car and most mechanics (even at Ford dealers) are unfamiliar with it.

I spoke to Shelby and they said the only authorized on the east coast was Tasca. is there anyone in Virginia/Maryland/DC that someone might be aware of? Even PA I guess. Thanks.

BIKEBOY Posted February 25, 2016 Report Share Posted February 25, 2016 (edited) Bruce, It's totally safe to take the car to AutoZone and have em plug in their OBDII under the dash and give you an "error" code. If it was my car (and I'm VERY fussy!) I would do just that. I have in fact! Start there..... It's free and it may be something silly. Chris Edit - Oh. And welcome to Team Shelby!

Like I said, I spent somewhere close to $20 for the OBDII reader and it's paid me back. The bluetooth ones are so cheap it's almost pathetic. If I were a manufacturer I'd make it an option for a bluetooth OBDII connection to connect to an app. In fact, with the "Sync" stuff it ought to just be there.

Chris--thanks for the welcome and the advice. I'm just a bit unclear what happens after they plug it into their OBDII (whatever that is!?). So if it shows an error code--then what? Tell the guys to correct it? Take it home and weep? Take it back to the nitwits that disturbed something?? Thanks in advance!

Since it seems like you are sort of green in this space it might be best to come here and tell us what code(s) are present. They will help tell if they are due to an incorrect tune being reinstalled.

It is probably just a sensor that is failing. As they have said you can go to any parts store and they can tell you why the engine light is on and what you need to fix it. If you are uneasy about replacing the parts yourself I would take it to a ford dealer. If you feel that it needs to be retuned there are couple places. Manassas Park, VA. I have heard some good and bad things about them. https://m.facebook.com/Excessive-Motorsport-308182886556/ New Provodence, PA Never heard anything bad about them. My car is in his shop right now. However he doesn't fix cars for a living. It is more of a side job. If you take it there it will be there for a while but it will be done right. http://www.jlpracing.com Where are you located? I have been in the northern VA area for 6 years and in all that time I have only seen one other KR on the road. Quote Link to comment Share on other sites More sharing options...

6-Speed Posted February 28, 2016 Report Share Posted February 28, 2016 (edited) It's unlikely the shop installed a different tune or calibration in your car. They could have done something wrong while attempting to replace the air filter. The DTC (diagnostic trouble code) code should be the first clue. Ford Racing offers an air filter that fits.

svtmattUT Posted February 28, 2016 Report Share Posted February 28, 2016 (edited) whenever a ford dealer has updated mine, they log it in the paperwork. Look at your receipt and see if there is anything that mentions that they performed a calibration update with a labor code by it. (They get paid for the work so they would log it to be reimbursed) Either way, get a tuner and look up the code. Also make sure the oil level is correct and that they reconnected the mass air flow sensor snugly on the cold air intake, both could have been affected based on your explanation.

twobjshelbys Posted February 29, 2016 Report Share Posted February 29, 2016 (edited) Hmmm, there should never be anything connected to the OBDII port. Are you sure there isn't some aftermarket doodad at the other end of the cable? Furthermore, it looks like the OBDII connector has been removed from its mount. If I recall correctly it is securely attached slightly above the bottom of the lower part of the dash panel. Can you get a clearer picture (in focus)?

dragpack70 Posted March 1, 2016 Report Share Posted March 1, 2016 Various insurance companies offer devices to plug into the OBDII port to track driving techniques, and Oregon, and possibly California, are experimenting with devices to track miles and road use for taxation purposes. There are also used car dealers that install devices to track their cars until all the easy weekly payments are made, but I don't know that they typically use the OBDII port. Also, some breathalyzer ignition interlock devices use the OBDII port. Quote Link to comment Share on other sites More sharing options...
Bruce2009KR Posted March 1, 2016 Author Report Share Posted March 1, 2016 Folks, I used my I-phone to snap some photos to see what's going on with the port under my dash. It appears their are two ports and clearly the one has been detached from what appears to be its slot. Again, the car is running fine so I don't know whether to leave well enough alone but it is puzzling to me. Let me know your thoughts. Thanks.
