Topic: Fowlhunter has a Diablosport Predator 87 Octane Tune

[MyBigToy]

We got him set up last night with the 87 octane tune. He's going to drive around for a while to see if we can keep the 2k-4k timing bumped a little once the computer adjusts for the new settings or if we will have to drop it back down to the canned tune parameters. We had a litle knock in that rpm range only. We adjusted shift points, firmness, and times. We also eliminated torque management and adjusted the computer for his larger tires. We plan to adjust the injector slope at a later time after the computer has time to learn and adjust for the new programming.

It will be interesting to see how the tune affects gas mileage on his upcoming trip once the programming settles down.

I also gave him a ride in my truck. I'll let him chime in on his impressions.

Very cool Joe.  We should meet at Gateway Raceways and do some test runs this summer.

Damn Joe, you beat me to it!! I was going to get something posted this morning but the phones here at work got kind of crazy.
I first want to say, many Thanks to Joe for his help installing the Predator tune in my Av!!!!!!!!!!!!!!!!   

As Joe stated we adjusted a few parameters on the 87 octane tune, the difference is amazing!!!!!!!!  Did I say  ??
We had a little knock in the 2k-4k range after we (He) made some adjustments so we (He) dropped it back a little. I'm going to keep an eye on the tune we put in last night and run a better grade gas on my trip to PA next week, maybe I can bump the timing up again, hopefully the better gas will help the knock? 

It will be interesting what my mileage looks like on my trip to PA!!!

OK, the ride in Joe's AV, that was unreal!!!!!!            
It was hard to believe I was in an Avalanche!!!!!

Funny you say that, were your ears ringing last night?

   I may be up for some of this!

Sounds like a GTG for the guys with faster Av's than mine?

  I may be up for some of this!   

I've been wanting to do it for a couple of years now.

Good deal!  Joe.

Are you bringing that with you on your trip?  When can do a quick check of your fuel trims while you're here and see where they're at.

Yes, I'll probably bring it with me.

yeah, should get the LTFT's / fueling dialed in first via the injector slope setting, before adjusting the WOT timing and stuff...  you may very well find that once you adjust the fueling correctly so that your average LTFT's are in the 0 to -2 range, that you can bump up the timing some more - since you'll have more fuel at WOT after the slope adjustment...  cuz I haven't seen one yet that doesn't run on the lean side and needs to have the slope adjusted to anywhere between -3 to -8% to richen it up a little, cuz the trims were off and positive...  

and after a flash, things should be relearned in 50-75 miles...
