I like it so far! It's got some very nice convienient things, if nothing else. It's great having the traction control off by default when the car starts up. That alone is worth a lot to me. The shifts do feel a lot quicker/harder too, since I bumped the firmness all the way up for all shifts (except WOT shifts, I wasn't sure about that).

There are a lot of little things I don't know how to do with it. Does anyone have any pointers they could give me? I don't want to run on anything but regular gas, so the fuel tunes are pretty much out.

I was wondering about the fans. Should I set all the fans to the lowest settings? I definitely want them to turn on lower, but I didn't know if that would be overkill or not.

Let's see. What are some good shift point settings? I have an auto (obviously). I'm trying to remember what I set them to. I think it was 6000 1-2, 5800 2-3 and 5700 3-4. Something like that.

I set my idle to 1100, but that's a little high. I'm going to readjust it to around 800 I think. I put it in reverse and it jerked a tad.

Anyone with diablo experience, can you tell me a few things I should do that I am probably overlooking? Plus maybe what some good numbers would be for some of the stuff I've already set? My car is a daily driver. I don't have a track anywhere near me, otherwise I'd tune it for that. So, I need daily driver tunes. To be honest, the full firmness shift setting might be getting lowered since I daily drive it. I don't know, I might just need to get used to it Isn't the car shifting firmer better for it? I'd heard someone say that before.

I'd be happy to let anyone know a few things about the predator if they have any questions. I know a lot of people on these boards wonder about a lot of hardware for their cars, and since I now finally have a predator, I'd be glad to help anyone out if they have any questions about one before they buy.

Now, if someone could help me out with my questions, that'd be great. TIA!

Wow, don't all jump on this thread at once.

One other question. When I install the diablo tune, is there any way I can get around having to up my gas to at least 91 octane? I'd rather run on 89. I'm thinking I could reset everything to the diablo tune, then maybe change the fuel settings back to a stock setup - or would that mess something up? I'm just messing around with this thing, so i'm trying to learn all I can. Thanks!

Well, I'm no expert, so i kept my mouth shut, but since noone is saying anything, ill chime in a little.

When you install the tune, as you know, it will advance the timing and change air/fuel settings. They say it's set up for premium fuel...92 octane, but in Cali, we only have 91. I haven't had any problems though. Personally, I wouldn't run it on 89, just to be safe. Whats $1.50 max per fill-up more to keep safer.

I guess you could run it on 89 and listen for pinging. I just wouldn't.

Also, with the diablo tune, the fans come on very early....it's actually annoying, b/c as soon as the car warms up all the way, they are on. I would definately not set them down all the way, it's too drastic! Do a search on fan settings or temps or something (i forget), and you'll get some suggestions...or maybe someone will kick in and tell you.

hope it this helps a little
Kyle

Thanks for letting me know those things. Like I said, I'm running blind on it really. The manual tells me what does what, not how to do all those things. I guess that's its job.

If I install the factory HP tune, then modify some settings, will that set my fuel ratio back to the stock settings and allow me to set stuff like shift points? I don't mean restore from the backup, I just mean using the factory hp tune on there (just to clarify).

Anyone got any #'s for what they are doing with their predators? If you do, post them here if you can. I'm curious as to what #'s people are choosing for some of their tunes, such as shift points, shift firmness, etc.

I reset all my settings to stock, then I set up some settings manually. That should leave the air/fuel stuff and spark timing stock, right?

I moved my shift firmness for everyday driving all the way to the softest possible setting. I had it on the firmest, now the softest. Trying to two extremes and seeing what I might want to go towards. I kind of like having soft shifts for everyday driving, and tuning the WOT shifts to their highest firm setting. I was impressed - my car barked second hard today! It sure hasn't ever done that before. I was pleased.

So if anyone has some #'s they'd like to share, that would be cool. I'm interested in what everyone else has going.
