If my Ec does not have the stock tune how will Diablo react? Will it simply read the existing tune as the stock tune or will it show a that the stock tune has been modified. I do not know that my stock tune has been modified but I appear to have 3.55s in the rear and the speedo reads right so i guess that indicates that there has been some change there. Side note: I have the Predator en route, should be here today! :SNSign:
Can DIABLO read existing tune?

Is it possible you may have a "Speed Cal" installed and don't know it? I can't see someone flashing the stock ECM with a handheld tuner and not providing the tuner to the next owner? These tuners "marry" themselves to the ECM when used.
Not sure how the Predator will react to an ECM that has already been tweeked.
I would think it would make a copy of it just as if the ECM's programming were stock.

thats true the tuners marry them self's to the ecm and store your stock tuning in the tuner
i doubt it will be compatable if you already have a tune installed. It would only be able to read codes and erase them thats about it..

I'm pretty sure you'd have to have it reflashed to stock before you can use the predator tuner with it. Usually, the tuner will error out when reading a tune that isn't stock.
It's dangerous to use the tuner with a car that isn't stock (if it were not to error when making the original backup) because the values you're changing don't mean the same thing anymore, so you'll really have no idea what is really happening. That could hurt some stuff.

First, handheld tuners are not the only thing that can flash the EEC. The dealer can do it to change for gears, as can several other companies like saleen, and steeda, so with that said it is possible that you have a re-flashed eec. I am also willing to bet that the predator will read the tune that is on there if it is different. There are several saleens that use them with the modified flash, and I've never heard of any of them having to put the stock ford stragey back in. As far as it being dangerous, it would not be anymore dangerous than adjusting the performance tune that comes with it.

I agree with jstreet0240.
I don't think you'll have any problems with the tuner reading a moded stock code. If you think about what the tuner is doing, it is only reading and saving your current program and locking it's self to your unit through the VIN number stored in your ECU.
Just plug it in and see I shouldn't hurt anything.

Ok. I got it yesterday. Installed last night and was not happy with the initial results. Shifts seemed to get softer , were lower in the power band and were making a brief high pitched squeal on the 1-2 and 2-3 shifts. didnt seem to make any extra power anywhwere in the band. So I started playing. Advanced spark to max, firmed up all the WOT shifts, bumped up tq modulation for all shifts, pushed rev limiter to 6200 at WOT, think thats all I did. Now I can feel a difference. Bottom end is uneffected but mid and top are awesome. Thanks for the help yall.
My Diablo Experience
Bought from Pro3. The deciding factor between it and SCT was the awesome price I got through SN :SNSign: . Bear in mind that I am this cars second owner. I got this car at auction so I know nothing about the first owner or dealership. So far I have been able to discern that the previous owner did the following; K&N FIPK, 80MM Lightning MAF, 70MM FMS TB, an as yet unidentified Cat-back and 3.55 gears. Did the install last night and was not happy.

I guess that there was some kind of a modified tune in her already, hopefully a dealer tune.
Some Questions:
Is it likely that the dealer would have tuned this car for these mods?
How far can I advance REV limit before I and really endangering the motor?
Where in the RPM does the power band stop?
I want to play with the fuel settings. Any input as to what would be an mild setting for fuel?
Is there anyway to get more on the low end of the RPM range from the Predator?

Whats a Speed Cal?

The Ford dealer is'nt gonna upgrade squat as to the factory tune. They'll tell you your warranty will be voided for any aftermatket part or part that contributes to engine failure. If it were me, I would'nt advance the rev limiter anything past what stock is. 6,000 for GT's? Your past your power band after about 5,400 on GT's anyway, unless it's heavily modded.

The dealer will reflash for gears, but they limit it to, I think 3.55's That is the extent of what they will do though.

Hell.... I'm afraid to let the dealership even touch my car!

I doubt they get much business from it anymore, since they limit it to 3.55's. In fact it has been several years since I've even heard anyone mention it. Most people wouldn't go with 3.55's anyway, unless it is an fi car which would be tuned already.

yeah they use to do it, but i didnt know that they had limited it now to 3.55's. A friend of mine had his swapped by the dealer and he had bought a set of 4.10's from FRPP, the service writer said it was ok as long as it was a ford part. They didnt reflash his computer though cause he brought a speed cal and all they charged was for the install.

with you mods you have no advantage to a higher redline. most cars actaully will have a quicker et shifter more in the 55-5800 range. so rasing the limiter from 6k means you may not bump it if you lose traction but it will not increase you et unless you do cams/intake mods to raise your powerband.
having the shifts lower in the band is sometimes better. you need to post in what rpm's the shift were at. for example if the old tune shifted at 5900 and the new tune shifted at 5700 without running it down the track or some kind of baseline you don't know if that is helping or hurting. you have to remeber a tuner is only good for a few hp. it is not a night and day mod. Also the fact you don't know exactly what was on the car before mean it may have had some timing in it already or something.
