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

Generaly only when you are gettin' on it.

 

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,

Any time!!

 

i don't have the predator, but i am still trying to get familar with it. you can call these guys whenever you have any diablo questions... these guys are great tuners and do an awesome job. DynoTuned Performance ask for Brent 757-549-3966

 

ya i have a shift kit in my aod and i dont even notice it while drivin from A to B unless i womp on it when a damn ricer thinks his fart pipe makes his POS into a race car

 

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.
