Hey guys, sorry if this has been covered, and I'm sure it has, but I literally know nothing about how to or reading tuning. I recently bought a 2002 Camaro, LS1 6 speed. When I got it home I was checking it out and was pleasantly surprised to find a Diablo Predator tuner in the glove box. Along with it was a note from I assume the previous-previous owner. (The kid I got it from only had it a few months and got in trouble w/ mommy and daddy so they made him sell his car.) Here's an abbreviated version. I'm leaving out the obvious and unrelated parts.

WOT Fuel Mixture
2k-4k +8% rich
4k-7k +5% rich I know the 2-4 and 4-7 is RPM, but +8 & 5% of what?

WOT Spark Advance
2k-4k +2% Advance in winter (Use 1% in summer)
4k-7k +6% timing I've heard of x degrees of timing but not %.

Idle
Park/Neutral: w/ac +100
Park/Neutral: w/o ac +100 Pretty easy, but thought I'd double check, +100 over stock?

Fuel Injector Slope
Minus(-)7 No idea.

All Torque Management
Off I'm assuming traction control?

COT Temperature
585*C No idea.

Please let me know if any of this looks off/wrong. I do t really want to have any issues late since it's my DD.

I still need to order the cable set and program from Diablo so I can data log and upload my existing tune to my PC. If the above "tune" is even what's in the car now. Any and all help is appreciated. Thanks for looking over for me.

Thanks, I'll give it a read when I get a chance and see if my little pea brain can obsorb any of it and make heads or tails. This is the first car I've had that had any type of tuner to even mess with. Now that I know it's been changed I just wanna make sure it's right, or atleast close enough to not cause any issues. So far the car runs great, aside from an exhaust leak in the driver side but that's for another day.

No one else has any input?

The fuel changes are based on % of commanded AFR, so if its commanding 12:1, and you add 10%, it will command 10.8:1

The timing is in % of total timing, if you see 20* at WOT, and pull 10*, it will pull 2*.

The COT change was to disable it, ideally it does not have cats installed, if it does, they're gonna melt

mthomsen224

In other words, since it still has cats, I should change the tune. It they're not already melted. Clearly, some people should buy a tuner if they don't know how to use it.

Would I be better off putting a stock tune back in it till I get the cables ordered? Or can I even do that with out the usb-serial and power supply?

Thanks Mike, this is the type of info and input I was looking for.

Yeah, just go in and set the COT param back down and make sure it's not set to OFF as well, and reload the tune.

mthomsen224

Can I do all that from the handheld, or do I need the cables and program do do all that?

mthomsen224

Does any one with a predator, or that's used one, know if I can change this on the handheld? I'd rather have some insite bonfire I go plugging it in and screwing something up. This is my DD and I can't afford to have it down for any reason.

If COT was changed previously, and it has cats, undo the changes in the handheld...

Nothing you do here is going to cause the car to be down for any amount of time....

mthomsen224

I'll give it a shot. Thanks Mike
