I ordered and received a Superchip. It was supposed to be custom burned to correct my speedo for a change from 3.55's to 4.10's, it was not corrected.

My Ford dealer has now offered to make the correction for me at no charge, I am considering taking him up on his offer EXCEPT--

A little birdie told me that any time the dealer makes ANY change to your ECU, such as this, his system will automatically update my code to the latest and greatest, Therefore, my chip will no longer work.

I would send it back and have it corrected but, unfortunately I didn't buy it from Mike Troyer and I don't want to be without it for three months.

Mike, help, is what the little birdie told me true?

 

If Ford does fix the speedo proble, then the minute you install your chip, it will override what Ford just did. You either need to return your chip, or get a chip burned properly. Even though you didnt buy ythe chip from Mike, he could do a custom burn on it for you. Good Luck

 

Hi F150Freaky,

Hmm, sorry to hear your Superchip apparently wasn't programmed correctly, but that really shouldn't take more than just a few days to get corrected, maybe a week to 10 days or so taking into consideration shipping time back and forth. If you want to have us correct that for you, just give us a call & we can make those arrangements with you for a very small fee, not much mroe than shipping & handling costs in some cases. Better still would be to contact whoever you bought it from and have them make that correction free of charge. Unless you have a vehicle whose code or model year makes that a problem, there's absolutely no reason it has to take a month, let alone 3 months, that's beyond absurd. Give us a call if you want to go over this, that won't cost you anything but the phone call.

Whoever you are talking to at your Ford dealer apparently doesn't know this, but they *cannot* make your speedometer read correctly in any 1997 & up F-150 with 4.10 gears using anything supplied to them by Ford. Why? Because 4.10's weren't offered by the factory on that vehicle, and your Ford dealer has no way to correct for gear ratios or tire sizes not offered by the factory on that vehicle. So your Ford dealer cannot correct for a gear ratio that is numerically higher than 3.73 in any 1997 or newer F-150, as that was the highest gear ratio (numerically) that was offered by Ford on any late-model F-150. In early to mid-90's F-150's that can be done by reprogramming the speedo cluster itself, but not in 1997 & up F-150's.

Even if your dealer *could* make that change, as soon as you plug the Superchip in you would no longer have that correction, as the PCM would take it's tuning & calibration instructions from the Superchip, so the Superchip would have to have that correction done for the speedo, odometer & shift points in the automatics to be right.

With regard to your specific question about whether or not having your dealer do this would *automatically* update your PCM to the latest software revision, that is not mandatory, but they are told by Ford that they cannot go back to any earlier revision (due to emissions requirements), and they generally have no idea what problems it causes you if they change the software revision. In general, they will usually go ahead and update the PCM too, you'll need to talk with them about that specifically to make sure they don't update the processor software revision level. However, given that they can't make the change you need for the 4.10 gears, this is a mute point, as you won't be having them do that work anyway most likely, once you read this post. If they *do* update that PCM's software revision (calibration, as they refer to it), they generally will *not* change it back for you to the original software revision, as Ford tells them they cannot. It all gets down to the individual technician working on the vehicle, their level of coperation and knowledge.

If you'd like to have us straighten this out for you, just give us a call, & best of luck whatever you decide!
