surging after custom tune
#21
I hope it is tune related, as I can think of something else you haven't checked.

The only way I have seen things like this get cured is when the tuner can look at a data log from the vehicle while it is exibiting the problem. Some tuners intimately familar with certain combinations and vehicles, can do it by experience. Most can't.

This is not always the case. I'll gladly take our mail-order files for the S197's and put them up against most dyno tunes out there. We tune literally hundreds a week with nothing but awesome results. We get back 100's of dyno charts, from cams and lockouts and nitrous down to simple bolt on CAI's or even stock airbox. It's about experience with the application. I've schooled dyno tunes many a times.
Don't take that the wrong way. I whole-heartedly agree that dynos are very powerful tools for small attention-to-detail. There are just many cases where you're not going to make more power or do anything fantastic over a mail-order tune. If this were forced induction, I'd be right next to you yelling at mail-order calibrations! I remote tune forced induction stuff with intricate datalogging, step testing and WOT (with air/fuel ratio results) last. However, in this case a mail-order tune is going to be just as accurate as most dyno calibrations out there. This makes a lot more sense from where I'm standing behind the scenes, but I'll say it anyway: there's only about 10 people in the country I'd let tune my 05-11 Mustang, dyno or mail-order regardless. It's about experience more than hands-on.

So, heres an update to the debacle Ive been dealing with. Im getting really frustrated.
1. Re-checked the CAI for bad fittings, air leaks etc. Everything remains as it should.
2. I went through the whole process of disconnecting battery, letting car cool completely, turn off all accessories and start car and allow it to warm on its own. I took it for a drive for about 15-20 miles. (Ive driven a total of 90 miles since Ive done this). All of this process was done based on the Ford owners manual and Chris from AM who advised others to do this on another forum to those who had similar problems. Its suppossed to allow the computer to "re-learn" how to idle correctly again.
3. I have not yet called AM/Bama. This is mostly because I work 14-18 hours a day.
The surging idle still persists and its driving me insane. Hopefully I can manage to find time to call AM and have them write me a new tune or I may be buying a bus pass.

With that being said, your case is DEFINITELY an isolated incident, and a byproduct of us doing 500-1000 different Mustangs a month. The more volume, you're going to run into the 1 or 2 that would have been an issue anyway.
It's more than likely just an issue with the tune file. Our tune submission form has a few questions that are a little confusing and bother the living crap out of me because they're always wrong.
Two ways to fix it... 1) Call Bama 888.226.9764 Monday-Friday 9AM-5:30PM EST and have them verify all of your modifications with us and check the tunes. or you can 2) PM me over your full first/last name and order number. Also make sure to include everything you have done to your vehicle including rear axle ratio, tire size, cai, exhaust, etc. etc. etc. Everything that would need to be included in the tune.
I'll look into it. Probably a tiny little mistake that we can fix within 5 minutes. Always call us first, it gets taken care of so much faster.

For the record, I want to be perfectly clear. I have no ill-feelings or anger with American Muscle/Bama. In my opinion they are at the forefront of Customer Service, Product Selection and overall quality. They came recommended to me by nearly everyone I know who has bought aftermarket accessories for their Mustangs and I will not only continue to buy from them in the future but will recommend them to others as well.
Happy Holidays.

The reason you will put your mail order tunes against other dyno tunes is alot of the dyno tunes come from idiots who had enough money to purchase the software.
The following comment is not about you and not specifically about the OP. But I get frustrated with people here who post drivability type issues with their cars after recieving any tuning. 9 times out of 10 it is the tune. Something is wrong and it needs adjustment. They call the tuner and the tuner says "It's not the tune". Well it is almost all the time, so it's frustrating that someone wants help or advice then doesn't like the answer to the problem so they ignore it forever until the inevitable hits them in the face and then several of say "I told you so".
Anyways off/rant.
Seems like you can get stuff together and get the tune ironed out. I have been there done that with having a tune go crazy in an FI car. Stressfull can't describe it when my motor is on the line.

Good luck... we'll get you taken care of!

I thought that I should give a bit of an update.
I received a new tune from Bama which I installed without issue. The problem still persists with the surging of the tach. However, now it only seems to happen when I come off throttle as I coast to a stop light or take it out of gear. It does it two or three times and then seems to steady itself. The worst is when I was going about 45 mph and nearing a semi-sharp curve and it stalled on me. Had to quickly start it again as I dead steered around the corner.
Additionally, Im getting about 11-12 miles per gallon now. Clearly not what it should be. My frustration consumes me.
Ill call Bama on monday and see if we can get it sorted out. Sheesh.

It should have read, "I can't think of anything . . . "
I had the same symptoms and an adjustment to the "dashpot" (I hope that's the correct term) was what was needed.
Car would idle great at a stop, shift nicely and drive good. When decelerating, it was alomost like the car was at part throttle. Rpms didn't surge, because it was in gear, but I could watch my AF vary up and down while decelerating instead of going completly lean into 17.9+. Usually the AF would read --- under decel in gear. I could also feel the car either accelerate or maintain it's speed. If I pulled it out of gear, the RPM's would hang at whatever I was at until I cam to a near stop.
