Computer Tune ?

[dontlifttoshift]

Carl, get your gun, it's back from the dead.

SkyRender got me thinking, so I started looking around.

I am looking at this, http://fordracingparts.com/parts/part_details.asp?PartKeyField=12346

Does anyone have first hand experience with it? I searched that part number through the whole forum and came up with a dyno test at Livernois but that was all. Very much trying to avoid the problems in the first post of this thread. I am very picky about driveability and haven't had good luck with dyno shops in the past, so I really don't want to do the custom tune if I can help it.

Donny, it's a bit of a cruise, but you may want to talk to Bryan Stepinski at Sutton Ford in Matteson. He did my tune, and had NO problem working with me to get the throttle modulation and dashpot values exactly where I wanted them. I did multiple test-drives in the lot and the area, then gave feedback. He tweaked the tune, and I went back out. The end result is beautiful. You'll need an SCT tuner, as they're an SCT shop, but honestly a GOOD custom tune is the way to go. Doing stuff via email is a pain, particularly if you want bespoke changes.

I’m running the standard STC 91 oct. tune (OEM engine). I like the extra power but I don’t like what they did to the throttle vs power curve. I get a huge jump in power when going from 0 to 50% throttle, and almost no jump in power from 75%-100% throttle. I would much rather it be linear, for every 10% jump in throttle it should produce a 10% jump in power. I know they do this so the average person who operates between 0 and 50% throttle 99% of the time when driving will “think” they have more power, but it’s stupid and makes the car harder to drive. Yes you can learn to drive around it and be fine but we should not have to!

Anyone know where I can get a good 91 oct. tune for OEM engine that has linear throttle VS power?? The way it is now bugs me so much that I will gladly pay for it to be gone!

I hear the Ford Racing tune is decently linear...but I have no firsthand evidence to support this. I think SkyRender runs that tune, you could talk to him. Any dyno tuner should be able to set you up with a linear throttle map as well

Hmm. Back to considering the frpp tu e I guess.

I've been using that for the past 2 years, and I have no complaints. I wouldn't expect any significant power gain, but the AP-throttle mapping is much better than the factory calibration. It's much more linear, and I think it makes the car easier to drive both on the street and at the track. You can actually engine brake without having to wait 2 seconds like you do with the factory calibration.

EDIT: It also eliminates the mandatory 1-4 shift, which is nice by itself.

I heard abiut pinging but im sure a catch can may help aviud the oil vapors getting sucked in and causing the ping.

 

[ddd4114]

The FRPP tune seems a little more aggressive with knock control, and occasionally I do hear it ping a little when I tip in. However, I work in engine testing, so I can hear knocking much easier than most people. Whatever the case, it's nowhere near enough to damage the engine, so I don't worry about it.

THAT is what I wanted to hear. Thanks!!

Every Bama tune I've had they ramped the throttle way up making it very hard to take off smooth. I think it's a very shady way to make people think there car is faster when it's not. I had Lito do a tune for me a couple weeks ago and not only did it make an incredible difference but the throttle and drivability are perfect as well. I have nt555 285/40's and went from a chirp at a dead stop to spinning into 2nd. Mid rpms pull a lot harder as well. I sent an email a few days ago to Bama stating the issues I had with them and wanting an explanation and they don't even have the respect to return my email. I will never buy another product there again.

I've always found it interesting to hear people describe their happiness with a given tune because they can now obliterate their tires thru the first 3 gears after its been installed.

I'm still on the fence about getting a tune because I want the exact opposite of that effect. Burning rubber is cool and all but it ain't gonna win any races while the other guy just hooks up and puts two to three cars on you while your trying to get the pig to hook up.

I want a tune with the same or LESS power off the line so I can go full throttle sooner and then have the power increase come on linearly midway thru 2nd all the way to redline. I haven't heard of such a beast yet thus the reason I'm still rolling around on the OEM map.

He'll, I would even settle for just a few tweaks to get rid of the dead spots in the OEM map and leave the power as it is.

Siunds like thats what frpp tune does

I used the traction as a scale of the change in power, it is easily manageable as the tires hook very good for street compound. 2nd and 3rd pulls extremely hard for having such a short mod list.

all of these comments just make it easier for me to justify the money I'm about to spend on a custom dyno tune. But I guess not everyone lives near a shop that not only specializes in Mustangs but also has a great owner/tuner and in ground dynojet. It will be money well spent. But even if I couldn't utilize live dyno tuning, I would still get email tunes then datalog back and forth till both the tuner and I were satisfied. This is my first Mustang but it has been the same with every car I ever had. Started with handheld/email tunes but always eventually found myself on a dyno doing a live tune to really get what I wanted out of my car/mods. My Mustang with my current Bama 93R tune proves to be no different. I have my appointment 7/12/14 I will let you guys know how it goes.

My current bama race tune after the cams, looks like they got rid of the pedal ramping.
I don't mind either way. I got used to it after a few days.

Less power off the line? Have you tried adjusting the tune connected to your right foot?

I'm not blowing off tires thru the first 2-3 gears because I don't have a tune, remember?

How much of the available torque curve in factory trim do you really believe you are using off the line without full slicks strapped on? I dont think even someone with "Mad Skillz" like yourself, apparently, can claim they are using all of the torque curve they have off the line to its fullest potential.

Damn straight though, If a tuner could configure a tune that made less power off the line and didn't have the Dr Jekyll and Mr Hyde throttle response that many report about I would check that option box.

Oh, no, it's never good when I get people thinking.

That's the tune I have; I think it is very good for corner-carving use, greatly improved throttle response, very good linearity, with outstanding street manners and driveability. I highly recommend it.

Do yiu fet the infamous pinging?

 

[Norm Peterson]

That's a whole lot easier to accomplish when if your foot only asks for 10% throttle opening, 10% throttle opening is all you get. The tunes that impress Harry High-School and his buddies or give a little advantage in a street challenge might be giving you 20% instead. Maybe even more than that.

Remember, the throttle plate in these cars is not mechanically connected to the pedal, and all kinds of nonsense can be inserted electronically on the way from pedal to throttle plate.

If you don't want to believe me, search through Terry Fair's 2011 Mustang build thread for all of the problems with just the stock tune, and how the car became easier to drive at autocross (and faster!) when driven in 3rd when 2nd should have been the most appropriate gear. Having to kill overly aggressive throttle opening by being in the wrong gear . . . is just plain wrong.


I've even had to deal with too-rapid throttle tip-in in a purely mechanical system. Even there it is not an imaginary situation.

FWIW, I've been running the FRPP tune (and its cold air induction) almost since I took delivery of my '08 over 6 years ago.
Late edit - it doesn't ever ping, but the fact that 93 octane is the easy stuff to find, 92 difficult, and only 91 all but impossible is likely the difference.
