Terrible Throttle Response after MODS

[CHAROLLS]

QUOTE FROM AMERICANMUSCLECOM:

"Knowing your Mustang Computer Code is crucial when it comes time to get a new tune. Whenever you want to have custom tunes created, your specific computer code will provide Tuning Specialists with the mapping of your ECU, showing them tables and graphs that are not the same with every computer code. Seeing this information allows them to dial in on the exact modifications you may have added to your Mustang and get your car running its best and at its maximum performance. To learn more about custom tuning, please check out the following links: Bama Custom Tuning Mustang Tuners"

Oh my god. Have I done goofed? Did I find my problem? (again, problem existed before tune/intake. but still!!)

Strangely, even after I provided BAMA with the wrong pcm code, CAN1, there seemed to be no issue with the transferring of data. I'll explain:
JLT intake + stock tune = idle is retarded. very very retarded.
JLT intake + bama tune = idle is perfectly normal. runs very well.

So...is my having provided the wrong PCM...okay?

no it is not okay... I find it even more odd that bama took CAN1 as a pcm code even though that isnt a pcm code... Seems like they would have followed up with you to get the real pcm code.

The images notes that EFB is the code. When I provided my PCM code for my car, I provided them with: CAN1

Could...that be the reason why? Would that make a difference? It's hard for me to believe that's the reason, because again, the problem existed before the intake/tune.

They didn't ask for the Strategy and SWPN info? Did you order the X4 with the tune or get them separately? They didn't ship you the X4 separately and then you had to get them that info from the car once you got the tuner and were able to hook it up to the car and read that info?

Anyway, this doesnt matter (not the actual reason for your problem) because the problem started BEFORE the tune/cai install. But I would address that after you find the actual problem.

Regarding putting the car back to stock, stripping off the mods one by one, that would be very difficult, as all my stock parts are at the shop, which stays open during the times I'm at work. I will figure something out.

Did you take it back to the shop that did the install? At the very least I'd install the stock CAI and stock tune...that itself takes about 20-30 mins tops. Take it to a Ford Dealer for proper diagnosis.

I'm going to echo Beefs post where it is not the exhaust or the size of the piping. I know you like to keep referencing your past vehicle, but it is not going to cause your problem as described.

Your MPG that you are saying your car is getting is very bad. Its very bad for a car to run super rich as it will wash down the cylinders and performance will be affected. I'd like to see you get this fixed but I think the only way for you to do that is to bring it to a dealer or have a mechanic look at it that has scan tool capabilities.

Even in the Americanmuscle website (I'm looking at it right now) I quote "Usually 3 letters and 1 number" for 1996 models and up. Then it shows a photo example: DWW5. These are the largest characters in the pcm sticker, and is located right next to "FoMoCo" writing.

This is why I thought my PCM was CAN1 - 3 letters and 1 number - check. largest characters in pcm sticker - check. Located right next to "FoMoCo" writing, check.

Anyone else think this is my issue with throttle response?

I quote myself again just for clarification:
"Strangely, even after I provided BAMA with the wrong pcm code, CAN1, there seemed to be no issue with the transferring of data. I'll explain:

Need4Speed15, I ordered the X4 with the tune, together. Received in the mail the JLT intake and tuning device - device was preloaded with the tune to accommodate the modifications I have.

I did not take it back to the shop that did the install - closed on weekends.

And yes, I'm thinking of setting an appointment with the dealer tomorrow, for Saturday. I'm just worried about the insane amount I'd be paying for the service.

 

[Need4Speed15]

JLT intake + stock tune = idle is retarded. very very retarded.

So you ran the car or attempted to with the JLT and stock tune?

I admit your problem is very strange, but I would treat it as a serious problem and get it looked as soon as possible.

Yes, that's weird you didn't provide any other info? Really weird. I've had multiple tunes and all of them needed the strategy and/or the swpn code.

Take the JLT off and put the stock tune back in. You shouldn't have to pay for them to check it out unless they find the reason is from something one of your mods caused.

What I'm saying is if you have a bad sensor or something mechanical that is causing this problem and it wasn't caused by a mod then they should take care of it under warranty.

I just put the tune back to stock, with all my other mods on just for the heck of it, and to see if there would be a difference with/without tune.

Car's in neutral, e-brake on, start car. Entire car becomes shaky. You can hear the intake sucking in air...maybe twice a second: SWOOSH SWOOSH SWOOSH SWOOSH as the entire car shakes.

Did NOT drive it. Turned it off after about 4 seconds.

OK...yes, that is normal because the mass air function is calibrated for the stock CAI diameter with the stock tune. With the JLT and stock tune you will experience a very lean situation which will cause the car to not want to idle.

Need4Speed15, Yea, exactly as I expected. So, fair to say that the tune works, even with my having provided the wrong PCM? Or do I wait for bama's response? Emailed a rep few minutes ago.

Regarding taking my car to the dealership - I want to take my car in AS IS, with all my aftermarket parts ON. Without a long explanation as to why, simply put, this method seems to make more sense to me.

I would want to hear from BAMA as to how they created your tune. I personally would get them your (stock tune info) Strategy and SWPN info and have them recheck your tune and make sure everything is ok.

This doesnt make sense to me as again the problem started before the tune/JLT. And knowing dealers some will just blame the tune/mods and some wont even touch the car. The only way I would do that is if you have a very mod friendly dealership (which also do exist out there). Also, most dealerships when diagnosing a problem the first thing they do is flash that latest strategy and updates to the computer...if they do that your SCT device will be useless and it will have to be unlocked by SCT to use again....and the car will not run with a stock tune as you have already experienced.

Again I would atleast put the stock CAI and tune back in the car before you take it to the dealership.

But you seem to keep wanting to do your own thing with this...so if you do bring it to the dealer just advise them and make sure they understand that there is an aftermarket tune in the car and to make sure the mechanic does not flash your computer with updates.

Thanks, Need4Speed15 for your take on this.

I will post here what Bama emails me back with, same day of when I receive a response.
I will TAKE my stock intake/sct device to the dealer as well, and advise them of all the mods I've done to the car and issues in order. If they see that having the car back to stock is absolutely necessary to diagnose an issue, then they can go ahead and do it themselves.

If the dealer charges me a grand a more, which I believe they will, whatever. I just want this fixed as soon as possible. I literally don't have time for anything - been skipping gym a lot lately as well (bodybuilding for 6+ years and powerlifting for 2+. These are my passion. And to miss sessions is...a big deal)

99% of the mods on my car I can not do myself, again because of lack of time. I do not hold a 9-5 job, as I'm a commission-only agent working 24/7.

With that being said - Need4Speed15 (and everyone else), I appreciate the help. EVERYTHING you said makes sense - from putting the car back to stock THEN taking it to dealership, etc.

To do:
1. Wait for response from bama - then post response here.
-if bama sends me tune again to accomodate new pcm code, will post results here.
2. Monday, schedule appointment with dealer for Saturday
-if new bama tune is given, installed, and car is fixed BEFORE Sat, no trip to dealer

Will update.

CAN1 is a computer code. I have the same computer code. On the 2015 you don't need the strategy for them to write the tune.

 

[Need4Speed15]

No prob, good luck with it. Hope you get it sorted out soon.

 

[Need4Speed15]

CAN1 is a computer code. I have the same computer code. On the 2015 you don't need the strategy for them to write the tune.

I've had 4 different tunes on 2 different 2015 Mustangs GT's and they all needed that info. Actually Lund just needed the last 3 digits of the SWPN code, but then had me check the other info also.

2011-2014 Mustangs the large 4 digit code was all that was needed...the 15's are different.

Check this vid out on how to get that info...

From Beefcake's site...look at the picture of the computer sticker...they (Lund) need the 3 digit code to tune:

From BAMA's site...How to read strategy code (2015 Mustang in pics):

https://support.bamaperformance.com...ow-to-read-a-Strategy-Code-on-Bama-SCT-X4-SF4

But then here they say: 2015 Mustang tunes require Strategy or PCM Part Number Only

http://bama.americanmuscle.com/custom.php

And here they have a pic showing the 4 digit code (scroll down to bottom of page for the 2015):

http://www.americanmuscle.com/computercode.html

Maybe BAMA is doing things differently then everyone else...who knows. But if I were the OP I'd want clarification.




Who's tune do you have? I'm assuming BAMA
