Bama tune worth it for a stock car

.7 second improvement with a BAMA tune and CAI? sorry, that is a little optimistic.
I did the 3 drives on the same day, what should I say. I made 3 logfiles with the XCal and fitted the speed curves afterwards with Excel.
The jump is from Stock 87 to CAI 93 octane.
But I have no comparison to other tunes. (Base set-up was from Doug)
FYI, the air intake temp is higher with the stock airbox, even at 60 MPH, thats a direct loss in HP.

Same here, I got the Doug BAMA tune through AM when I first got my Cai and tuner. When I added 3.73 gears later (post-Doug) they revised the tune and it wasn’t nearly as good and very jerky on cold start up driving.
Lito cured that for me when I got his NA tune

I tried to find the reason for this jerky drive, found that the trottle body is closed right after full clutch engagement, despite the gas pedal demand was ok. So gas pedal was 10-15% and TB 0 (!!!) for some tenth of a second. AM fixed it for me, but it came back with next tune revision. I was thinking to get the Advantage software to change the driver wish map by my own.

BTW: The service ticket procedure at AM now is painful

There is a place called mustang magic in long Island. Great people took my car there once. But mostly to do routine stuff like oil change. I was thinking about taking it there this saturday and have them diagnose it. BTW the hesitation gets worse the longer you drive( each session ).

I know MM, never took any of my cars there for work, back in the day (15 yrs ago or so) they had a very mixed reputation.

I always used Realspeed for mine.

I wonder if this could be your issue?

Hey stkjock thx for that TSB post. I think my car could either have a fuel pump issue or torque converter like you said. The car hesitates a lot when slowing down and stepping on gas. the car runs smooth when you ease on acceleration on highways but when you step on gas it's very inconsistent.

Sometimes the engine would get loud but there is a feeling of loss of power acceleration is slow. or sometimes when it does speed up its very jerky and not a smooth acceleration. Not to mention slowing and stepping on gas or from stop and go there is a lot of hesitation. Car would take a second to move forward. It acts like as if I am pressing the gas from Neutral and then jerks forward when moving.

Something else to check is the ...'sock filter' that goes at the bottom of the oem fuel pump. If that gets
clogged up, it will run like crap and your fuel pump duty cycle (FPDC) will increase a bunch. Then there is the oem fuel filter....on the rail next to driver's side door.

I have an aeroforce gauge plugged into the obd port at all times. Then you can see at a glance what is..'normal'. It will also spit out every parameter on the 5r55S you want to know....like slippage, tranny temp, etc. I note down what is ....'normal' for the various parameters off the obd port. Then if things go screwy, then I can compare the original data.... and the new data.

I have a Brenspeed CAI and tunes; 87, 89 and 91 octane (from 2007); on my '07 GT and even the 87 octane custom tune runs circles around the stock tune. My 87 tune is a great street tune, most responsive in the lower rpm range. The 91 tune is a dog in town but excels on the track in the upper rpm range. The 89 is a good compromise of the 2 and i run that 99% of the time.

A good tune not only will adjust for your preference in octane choice but a good tune will also affect shift points.
None of that even makes sense. Your 91 tune should run just fine..and pull like a mofo around town. With your slight incremental increases in octane, all they can really do is advance the timing a little bit. They should all work from idle to redline.

FYI: Got a new tune last week, much better trottle behavior than the old V2 tune.
I would like to figure out what they changed, but no software to do it.

Unless they gave you the actual .mtf file, there is no way to see what was changed. And you would need the old .mtf too.
This is something I dont like about SCT. You cannot pull a tune off the x4. Only delete or load tunes. Cant load an .mtf without the software. Device updater can only load .cef files, which are encrypted and will not open w/software.

They may actually have undone some changes in the driver demand/effective throttle area of the tune, but this is pure speculation on my part.

Yes.
Would it be possible to read out the ECU with the Advantage software? So, load the ECU with the tune and read it out again?
Thanks!

No, cannot read it with SCT.
HP tuners is the only tuning system that actually reads the pcm. Good news is, if you know someone with the setup, you dont need credits to read a pcm. Only need credits to write to it.
You would need to read the old tune also to compare.

So if you have only the Advantage software you have to start from default and cannot read out the base tune from the OEM Ford setup?

I have only minor experience with reading out Siemens ECU with the Galletto 1260, modify with WinOLS and write back. WinOLS is very painful to use. Supercharger tuning, only 2 lines in fueling table had to be changed for the smaller pulley.

Yes, with the PRP, you start with a tunefile provided by SCT.
So you save the file and load it on the x4. If/when you need to change something, you do it to the saved file. When loading the file to the X4, you can name it whatever you want. But you better remember what tune you loaded last to make the next tweak. This gets really confusing if you load several tune versions onto the x4. Remembering which was the best one... A total PITA. And the X4 cant tell you what was loaded to the car last.

Im used to read-edit-reload tuning the 91. No question what was loaded to the car as the tune was read from it.

This is all about licensing, and preventing someone to read and copy a big name tune. If you want to read the pcm, you need HP tuners or PCM flash.

Pcm flash is a generic obd flash software. You need to get the flash hardware for your specific model. And then pay someone to map your strategy, and you can edit it with TunerPro (free software).
Hptuners, sct, or pcm flash all cost about $750 for you to be able to tune your car.

Many thanks for your explanation. Thats not convenient. I'm sure in the future it will be more painful if it is possible at all with this air pollution restrictions coming.
New cars starting this month has to monitor fuel consumption in real time, store it in a non eraseble chip and the EU has plans to read it out in realtime too. I see new taxes coming. Part of the New Green deal.
Dark times ahead......

To my knowledge, smog testing is not checking for a "tune" at this time. Only for OBD monitors. Once they start checking, SCT will be the only one you can use as they are EPA compliant now since the lawsuit.
