Ah, that sounds cool for when racing, but harder on the tranny over time?

Take care,

Driving slow.... shifting softer...... full throttle..... shifting firmer. Get the idea? Just remember if you baby it too much.... it'll run like a baby.

Yeah, I think I got it. It'll shift firmer when really on it, but nothing to worry about when doing normal driving? Thanks man, appreciate it!

Take care,

As an FYI, I email diablo's tech support about the 87 octane tune. They were very general in response and basically said that they don't support 87 octane with their cookie cutter load and that a 120 dollar (not including the 35 dollars kit for the pc) custom tune would be needed to use 87 octane.

I guess maybe I can ask my questions here and get better answers.

1. I want to use the tuner to improve my automatic transmission characteristics. This should not require better gas. Based off the screen shots, you can adjust shift firmness. What is the advantage to making it firmer as opposed to looser? What are the disadvantages.

2. Has anyone had experience with the MicroTuner AND the Diablosport Predator? I know the Microtuner has some built in tunes for 87 and higher gas. I just don't know if you can get good custom tunes - one day I'll have a SC.

3. Has anyone used the Diablosport Predator higher octane tune, running 87 octane in a Mustang? I don't really want to pay 120 for a custom tune until I have some more stuff on my car.

Maybe others have the same questions, so hopefully this will be a useful thread.

Take care ya'll, and thanks for the previous posts and any future.

Yes and no. A firmer, quicker shift means less slipping of the clutch. In effect, the clutches will last longer. However, a quicker shift is done by increasing the line pressure. This puts more pressure on the seals. Too much can cause leaks. There's more stuff about this on www.tccoa.com. Their section on transmissions should answer a lot of your questions.

I don't think that's entirely true. I remember reading some FAQ or response from a Diablo dealer about the 91 octane issue. The Diablo tune is basically doing what a Timing Adjuster does. It advances the timing to squeeze out more performance but this requires running a higher octane fuel so you don't get pinging. You can take the Diablo Predator's Performance Tune and back off the timing setting until you don't get any pinging with 87 octane. You won't get the most out of the Performance Tune though.

Hey everyone, thanks for the posts. This all makes sense. Propellerhead - What your saying definetly makes sense - but it seems worth the sacrifice.

As an FYI, 5.0 Mustang has an article about the Predator for a 4.6 SOHC. They raved about it, but I have not been reading those magazines long enough to tell if they'd actually complain.

Additionally, I tried to get more information from diablosport via tech support about an 87 tune. I think it goes right along with what propellerhead said. They say they'll improve tranmission shifting, and gas mileage with an "87 Octane tune". I personally think it is BS that you'd have to pay extra for that. However, it should be easy enough to get the tuner and
1. Change it so the speedo is right for gears
2. bump up the shift firmness a bit and monitor...continue and bump back when overdone.
3. bump timing and monitor - continue until not right.

Plus they have that data logging stuff that might be useful for troubleshoot the timing side of life. All-in-all, the predator seems like a better purchase over the Microtuner. The Microtuner seems limited in configuration and outdated - even though it does come with a base '87 tune.

Hopefully this information is useful to more then just me. haha

Take care everyone and thanks for the help.

Take care,
Ceyko
