so, who else is getting Diablo Predator?
share your opinions about the product !

 

From my response to another post about the DiabloSport Predator:

"Just did a full dyno beta test last night with the Diablo Sport Predator. Initially their preset
performance tune gained a best of 2 RWHP. In the end we set the A/F all the way to 5% lean and left the timing in the same position as the performance tune (which may have been the same as stock since we forgot to check). This netted us a total of 7 RWHP and 8 RWTQ. I also compensated for my 3.73's, disabled the CAGS light (already had the !CAGS installed but this disabled the periodic light too), and permanently disabled the SES set by the O/R Y. I can change the fan settings, use it as a diagnostic tool, and restore factory settings at any time. All this and I don't need to buy a laptop or a cable. My A/F is sitting right at 13.0:1 through most of the power band and just under that at about 4800-RL. It is fully net upgradeable and is easy to understand and navigate.

Honestly, I don't see a downside to this thing. The only dyno test I've ever seen on the HPP3 showed -2 RWHP/-3 RWTQ averaged over 3 runs. It's essentially a very expensive speedo calibration tool IMO. It doesn't even compare to the Predator. LS1Edit is a great tool but you need a laptop and there are tons of configurable parameters. It's an impressive tool for the avid tuner, maybe even essential. But I think most of the LS1 garage mechanics (like me) will never use the additional functionality of it. And the Predator can catch up in the future anyway since it can be upgraded. It will probably never get to the same level but I don't think it ever needs to."

BTW, I noticed you are in SF. Would you be interested in a dyno package that includes the Predator? The dyno shop is in Fremont and the owner is a friend. He has some of the units in stock and we are trying to come up with a good price for a dyno package. So I'm helping him spread the word. Let me know if you are interested.

 

What a small world <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
are you talking about George and his dyno?
Are you also talking about Rick with silver firehawk?
Yeah, i will be at the dyno pretty soon, may be this or next week (I hope so)
I was wondering if i have like 2 PCMs and i like to change them fromtime to time (ok,ok me is weird) can i do tune both pcms with the predator or it would accept only one VIN/PCM?
Can it store my different configurations/setups for my PCM(s)?

I've proved this on multiple LS1's, and also I did the same thing that you did on 2 other LS1's and managed to best the hp/tq by using timing only instead of leaning the vehicle out w/ just the fuel trim setting via the Predator.

One of those customers was running rich, so heh tried leaning via the fuel trim setting and he gained less than what you did. They weren't happy w/ the gains, so I had them go back to the dyno 2 days later and use just timing first. On the last run I instructed them to go just -1% (leaner) via the fuel trims, and he gained 12 rwhp, versus gaining nothing, and his a/f's were right on.

The other customer, a friend of mine, I dialed in myself. We tried just leaning the vehicle out to try and bring the a/f's in line, and we gained about what you had. Then we went only w/ timing only and gained 15 more rwhp than stock. The a/f's leaned out to the appropriate range as well.

As for timing, the base Predator tunes on the F-Bods are about 19 to 20 degrees, so by adding the full +10% then you're only adding another 2 degrees, and by taking away the full -10% you're only taking away 1 degree (because it works off of percent). You can also add more fuel than you can take away fuel via the Predator.

In order to correct your speedometer, for now, you must do this:

If your stock gear was a 2.73 and you upgraded to a 3.73, then set your "Factory Wheel Size" to 245/50-16 (25.66 inches) and your "Actual Wheel Size" to a 175/35-14 (18.82 inches) This will effectively take your gear calculation to a 2.73 from a 3.73 w/in your pcm.

If for some reason your factory gear was a 3.23, then you will need to set your "Factory Wheel Size" to a 245/50-16 and your "Actual Wheel Size" to a 205/45-15 (22.25 inches).

Try it, you'll thank me for it <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Now, there will be a revision update for the Predator later this week or next week that will fix the speedo issue w/in the F-Bodies for when they have an aftermarket gear other than factory.

Hope this helps <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

The Predator marries to your VIN. You can reinstall your factory tune and go back to the Predator tune at will, but the Predator will not tune another vehicle once you have initially tuned 1 vehicle with it, regardless if you untune that vehicle. This may seem like a downside, but because of this the Predator will allow you to effectively retune your vehicle even if your dealer reflashes your pcm, whereas other units will not allow this, and if your unit is stolen it is worthless to the thief.

TomQ: Damn, it sure it a small world. Yep, it's George! He has a few Predator's and I helped him do his beta testing. George is a good guy and I'm sure you'll be happy with the package he's worked out. Just tell him Jed said hi when you go in. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

BfB: That's some great info. Now I want to head back to the dyno and try adjusting the timing only first. But we had the A/F adjusted to a full 5% lean (after testing at 1% and 3%) and advanced the timing all the way to 10% and lost a few HP. We backed the timing out to 1 degree of advance and lost about 1-2 HP. So we headed to the other side and retarded the timing back 1 degree and started losing power. So we left it at 0 and called it a night. It never knocked or pinged even when fully maxed out. But it also didn't make any more power this way. It sound like we need to reverse the process and see what happens. I thought it seemed like the speedo was still off. But it was hard to tell since we were measuring front to back and using family radios. I went from 3.42's to 3.73's. Do you have the correction factor for that? If not, how can I upgrade in the next couple weeks when the gear calibration gets fixed?

BTW, are you planning on programming in a permanent disable for the DTC's? Mine is just for the O/R Y but I would love to permanently disable it. Thanks. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

BFB, I have a quick question, I just ordered a predator and you said that it starts off at 20 degrees timing. So does that mean if I want to set it to say 28 would I have to bump it up 40% cause it started out at 20 and just added 8 or would that then add 8 degrees to whatever my stock timing is?

 

Hey BFB,
What's the correction for 3.23s to 3.42s?

You can gain 10% up or down (2.2 degrees approx.). If you decide you want more timing then you'll have to have this done in a custom program. The key to remember is that timing can change because of load and conditions. Just because your base is 22 will not mean that you're not getting 28 degrees.

Idle adjustment is in the works as well. There will be upgrades for the existing units. If the software was complete for these settings, then the Predator would be capable now so long as they have a revision update. Even if these are not added in as end-user options then they still will be available via a custom program.

Okay, if you have a NON FACTORY GEAR in your F-Body, and are using the Predator, please, at this time go to your Wheel settings and adjust using these #'s below, as this will correct your speedo. This is a temporary fix until the revision update is released. I will keep everyone posted as to the progress of the update.

Hope this helps!

So, if I buy a Diablo it'll be worthless to anyone else if I try to sell it? My plans were to use the diablo to get me to a certain point, and then step up to LS1 edit. Can it be sent in to be "re-flashed" so someone else can use it? I'm not interested in buying it if I can't get any money back out of it when I go to sell it.

-Brandon

 

BfB, I will need a custom tune for my car. So with the mods in my sig and deleting EGR What would the custom tune cost me? And what else would you need from me?

2000 NBM Firehawk #542, S2 H/C, Macs, LS6 Intake, lid & 160 T-stat

BfB: thanks for the calibration numbers. Yeah, unfortunately here in Ca. they only give us 91. So it's probably is a good thing we tuned it the way we did. And actually, the best overall improvement was 10 at the wheels. 7 was just the peak HP increase. I'm still plenty happy with the improvement.

BTW, if anyone in northern Ca. wants to get a dyno tune package for the Predator, E-mail me. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
