Tunning a STS Kit w/ Predator? Hey guys, I am a new STS kit owner thanks to Jesse at JL Turbo aka SSnakekiller, I have the kit installed and i just brought a predator that needs to be reflashed. Sent it out today and i was wonder if I can tune my 2000 stock T/A with the Predator? It says that "The power enrichment we will allow up to 5% increase or decrease of fuel trims at WOT" Also "the spark we will allow up to 10% increase or decrease of timing in the WOT range"
Has anybody used this on any turbo/SC set up and got the tune near perfect? I want to have a "safe" tune since i live in florida so does anybody have any numbers for timing/fuel?
THANKS

Well congrats on the STS Turbo; I'm looking to buy one in a few months. With the predator - I'm not sure if you'll be able to tune it well with that programmer itself. Did you get larger injectors? I don't think it can adjust the IFR (Injector Flow Rate) table. The main thing is your timing table has to be totally remapped, and taking 10% out of the WOT area won't do it. Your best bet with that programmer is having diablosport do one of the email tunes for you. I don't know if they can tune a turbo setup appropriately, but I would definitely ask. If not you are looking at getting a custom tune, or buying something like HP Tuners or LS1 Edit to get everything in line.
I wouldn't get into the boost until you back the timing off some. I think most people run about 20* max timing for starters and go from there. Quite a difference from 28* or so on a stock NA car. Also for a boosted car, I've heard around 11.5 to 1 AFR is ideal, but don't take my word as gospel. Although better to be overly rich then lean
Most people like to shoot for 12.8-13.0 to 1 AFR on an NA car just to put things in perspective.

Sell it and buy a HP Tuner. www.hptuners.com
I tune LS1 cars and on average a 5% change to your PE will only be about .5 in your A/F Ratio.
I tuned a LS1 ATI supercharged Rx-7 before and it seem to like about 22-24 degrees of timing with 5lbs boost. It did have a very large FMIC too.
If your car is pretty much stock, your injectors should be fine with 5lbs boost, but you would be getting close to the limit. Next step would be to get SVO 30lb injectors....

The advice is, forget using the Predator for any
substantial mods. The only way it can even touch
most of the things in the PCM, is by the "custom
tune" process. Not as-delivered. You should take
the advice you've been getting.

i dont plan on just hittin the tune it button and calling it a day. Predator can adjust the parameters of the fuel and timing table my question is will it be able to adjust it enough so that it can run safe?

It only has 3 degrees of spark (+/-) and about one point of
AFR adjustment "allowed". Its spark curve cannot be detail
adjusted, only blanket changes, where for boost you would
probably want to take more care (let alone that 3 degrees
of spark pullout may not suffice, and when you "install
performance" it adds at least that much (so full subtract
only takes you back down to stock).
It's just not up to the job in most peoples' opinion. I bet
if you asked in the Forced Induction section you would
find few, or no people who've succeeed with that tool,
without a whole bunch of custom-tune hand holding.
Now, if PSL is what you consider convenient driving from
Delray Beach, the DiabloSport facility there can likely do
a dyno tune for you and then rig your Pred so it's centered
up for that result.

No; It can not adjust enough to compensate for those mods without getting a custom tune done from diablo. Just sell it and go with a more complete tuning tool, like HPtuners.

I originally suggested Edit or HPT, but I think at the time you were not so comfortable with the price and complexity. I have no experience with Predator, but I know they can do custom tunes and a good tuner should be able to get a decent conservative tune for his Predator. I was not aware of these limits with the Predator. It will only allow 3 degrees to be removed???
Jeremy, I will suggest these three options:
1. You do a Predator custom tune
2. You sell Predator and get HPT and we can go over it together
3. You pay for a dyno tune...probably same price as buying HPT
Let me know...

Thats what i am talking about 10s with a Predator! Now what kind of custom tune did you get? Did you have to take your car to diablo to get it tuned?
