    My son has a 2002 GT. We just recently got the rebuilt engine back into the car after having been out for three years. The following are the modifications: Manley forged pistons at .030 over with moly rings and 11cc dish yeilding 10.53:1 compression with the stock PI heads. Comp Cams Stage II cams (I can get the cam number or specs if that helps). BBK full length headers and catted X pipe. It also has some no-name CAI, which hopefully he will remedy with a BBK 78mm TB and CAI kit eventually. He has ARP main and head studs and the rods have ARP 2000 bolts. The crank is a stock refreshed unit and there's an ATI damper hanging off the front and Centerforce clutch off the back side.

    As you can imagine, it runs on the stock program, but not particularly well. All 4 O2 sensors are brand new. We are getting occasional codes P0152 and P1152. We haven't driven it very far for fear it's running rich and chancing melted cats.

    Here's the problem: I bought him a BAMA/SCT Rev-X tuner w/ lifetime tunes from American Muscle for his birthday. I had them write a 91 octane performance tune and 93 race tune based on his engine. After downloading over WiFi direct to the tuner, it would not load the tune on the car. I kept getting a "General Error#:0" immediately after selecting which tune I wanted to load. I called AM and their solution was to email me the tunes and manually load them on the tuner. That worked to alleviate the above problem and I got much further in the programming process. The tuner downloaded the stock tune from the car but would freeze with the screen saying that it was applying the changes to the tune that I selected before it got to the step to write the new tune. This happened even when I chose to skip the step where I could make changes to the tune. The first time I tried it, I waited with that frozen screen for over 40 minutes because I wasn't familiar with how long that should take. Bama says that screen should not appear for more than 30 seconds.

    Five calls to AM & Bama later, Bama had me try loading the included 93 octane tune for the stock engine. The tuner was able to successfully write that tune onto the car and it started and ran. It's obviously not at all correct for the engine. Bama then wrote a "Stock custom tune" based on the EEC-V engine strategy number from the car and sent that to me. The tuner froze at the exact same place as the AM custom tunes. I was then told by Bama that this is a known problem with the 99-04 cars. The tuner cannot write any custom tune to this car. Their engineers are supposed to be working on it, but they have no estimate for a time to fix the issue. I was able to return the car to the stock file on the second attempt.

    I would just return the tuner for a refund and go with another manufacturer, but from what I'm learning, SCT/Bama is the only game in town for this older generation of cars short of going with a full standalone system like the Holly. I even called Anderson Ford Motorsport, as they are relatively close to where I live, and they don't have a solution to tune his car either. Does anyone know how long this has been an issue with some of the 99-04 cars for SCT? Does anyone know of an alternate tuner solution short of spending a couple grand on a standalone and dyno tuning?

    SCT says this problem affects all their devices, so returning the Rev-X for an X4 will not solve the problem. They also said they cannot flash any tuner back to a previous known firmware that works with these cars.

    I did post this exact request to several FB groups and one member stated they had a similar problem with the Rev-X that was cured by switching to the X4. I've requested his fimware number to make sure he didn't simply get an X4 with an earlier firmware that doesn't have this issue vs the firmware that was on his Rev-X.
    Any thoughts or suggestions?

    First, Bama is not the only game in town for these cars. There are plenty of tuners out there for this generation. There are a couple on this site.

    Second, send the tuner back and get your money back. If you're going to do a remote tune talk to 04sleeper or Malcolmv8 on here.

    I have a 2002 GT, and every tuner out there can write a tune for the car.

    I have an SCT X4 that AM rebranded as Bama. It is still an SCT.

    The people listed above are great and can help you with no problem. They can likely help you with the handheld tuner you already own.

    I had the same problem with my 04 kenne bell 2 valve. I am using the x4. Mike Murillo tune. I was trying to change to the 6psi tune and froze in the middle of the upload. I have heard from SCT that on these cars if the voltage is too low it could interfere. I tried a fully topped battery to no avail. I even tried the full battery with all other electronics off. Door closed, lights off. I then went into troubleshoot mode. I checked voltage at various locations around the ecu. All looked good. After a couple of days of just sitting, I decided to try again and it worked. To this day I don't know what was going on. I will be going stand alone one of these days. Maybe jiggling the wires helped, I don't know. Next time I will just blow on the ecu like the original Nintendo cartridges. Tired of paying tuners. Nothing against tuners, I just keep changing my mind on engine swaps. For some reason my 01 4.6 f150 lightning swap can switch tunes left and right. Good luck.

    SCT recently did a firmware update that is likely causing the issue. I will not be updating the firmware on my tuner.

    However, there are a lot of tuners that can tune your car without any issue.

    If AM sold you the tuner, and then stated they known there is an issue, get a refund and look elsewhere.

    Not to bash AM, but they have fallen in regard to their service in the past couple years. They are not the company they once were.

    It's definitely not a voltage issue. They suggested that as a possible problem. The battery is new and has been sitting on a charger/maintainer for weeks prior to the engine install. It cranks fast. Just to humor them I put the charger on it while I attempted to program and it froze in exactly the same step.

    Just to be clear, AM sold me the tuner. When I had the first problem writing the tune with the WiFi download, AM made the suggestion that we try emailing the tune and loading it onto the Rev-X via my computer. That got me much further along in the process to the point where I experienced the Rev-X freezing. AM didn't know what to do from there and passed me along to SCT. I spent most of the day on several phone calls and it was SCT that finally told me that this is a known problem. They don't know when it will be fixed. They're not being very exact about how long they've known about it. AM has offered to exchange the Rev-X for the X4. I've been having lots of conversations with lots of people about this and that is likely going to be our first attempt at getting this resolved. I need a tuner device regardless of whomever eventually writes the tune.

    The AM tuning team to my knowledge are not trained, or properly paid, to write tunes. I only have a Bama badged tuner because I bought it with the car. The tuner is married to the car. So that was a plus for me.

    Steeda is a great place for tunes, and they will help remotely dial things in (as will the tuners listed above). Lund is another great tuner.

    FWIW, you don't need the latest and greatest tuner just to load a tune. The issue comes when SCT stops supporting it. I used an Xcal2 for close to 10 years and never had an issue. Until I switched cars that is. Then for some reason it wouldn't show as unlocked even though it was. Oh, and I never updated it.

    The current X3 I'm using was used on 3 different vehicles that I know of. Personally I'd send the tuner back and look for a used X3. Or if you're not comfortable with that talk to someone that actually tunes and have them send you a tuner with a base tune.

    Unfortunately, it looks like I get to pay return shipping to AM. Just got the RMA email. Small price to pay to get something that works, but considering they were the ones who recommended the Rev-X to me over the X4, I'm not very happy...

    EDIT: Eh, I should have waited a couple minutes before posting this. I just got a return shipping label in another email from AM. More satisfied now. From what I can tell, AM wasn't aware of the potential for the Rev-X to be a problem with this car, so they are standing behind their sale and making it right.

    Rev X in general are having a ton of issues, I had about 5 and had to send in 3 for warranty, I would never recommend them unless you have 18+ and need it.

    Just need to make a post to clear something up. I was under the mistaken impression that SCT and Bama were the same or associated companies. I've learned they are not, so all the references in my OP about Bama should actually be SCT. I've never spoken directly to Bama. I did call the FL SCT offices several times yesterday.

    It happens.

    I have several different tunes, from different tuners loaded onto my Bama stamped SCT. I need to put a decal over the Bama logo.

    SCT is pretty old news for tuning those older fords the old method of flashing tunes is pretty antiquated. About 10 years ago Moates released the quarterhorse for the EECs. It cant have any of those problems and is far superior to SCTs offerings. Not only that thr custom tuning software is free so if your one of them people always making changes its a must have. All the free support is on EFIDynotuning.com If you want to become a premium member there it includes free custom tuning so if u make a change down the road just simoly post up a log in your private tuning thread and youll get sent back an update.

    We got the Rev-X replaced with an X4 today and the tunes programmed to the car with no issue. Car runs much better now. I have a different person writing me some better tunes, but at least the car doesn't die every time you press in the clutch now. Still getting codes P0152, P0155, and P1152, so we have to sort out the O2 sensors/wiring. Thanks for all the suggestions here!

    I'm glad to hear this. Good news.
    I love my X4. So far it has proven to be a good handheld.

    1998 Mustang GT PI swapped. I get the same thing error code 110b8. I purchased both the rev-X and x4 both still have the same error, both sent back. SCT said the same thing that they have software issues with these years also. Today per the SCT Tech said there’s really nothing new we can put forward at this time. Not one time did they offer to look at the device and or the tunes. So it's been a year and a half and no tune. I live 45 minutes from there office to show them what it was doing, they said it was software and I might get notified if it was corrected. looking for a different tuner!
