Making adjustments with XCal. 2?
I was messing around with my xcal 2 tuner today and I got ready to make some changes with timing and spark just to see what would happen but then I got to wondering if I could mess something up. Has anyone messed with your settings? I have always wondered if I could fine tune it some to make it best for my truck. Another question is how can I use the tuner to adjust for different tire size?
Thanks!
Thanks!

Woah woah dude... careful.. don't get too crazy with the Spark Advance.
It's funny.. I just got an Xcal2 and my tune..
Here's my story from earlier today:
yeah I don't know if that helped you out at all.. lol..
Here's a thread... it kinda gets off-topic here and there.. people fighting n whatnot.. uh... have any questions just ask.. I'm learning a lot about this tuner..

It's funny.. I just got an Xcal2 and my tune..
Here's my story from earlier today:
Weird Issue... Under hard acceleration only with the tune, I get pinging. I think.. It sounds like rattling cans under the hood.
I had 1/4 of 87 low grade, I filled it up to 3/4 with 90 octane.. so whats goin on? fuel? do i need t disconnect the battery?

Got my tune.
I had 1/4 tank of 87 in, I filled it up to 3/4 tank with 90.. it was pinging.. I put the Spark Advance down one from 2000k-4000k, 4000k-8000k rpm and it went away.
This tune definitely made a difference, shifts are a lot more firm and responsive, acceleration is improved greatly.. even with my 31" tires.
Once I'm sure the tank is completely full of 90 octane, I'll put the timing back to the tune's default.
Everyone should get a SCT Tuner!!
I think I'm going to be getting fuel from Chevron only from now on, they have pretty good fuel IMO, good cleaners.

Nah, they're really nice and informative. Some people though.... as I'm sure you have a few over here.... are just... blah..
Try what I did, just retard them by One.. [in the rpm ranges you have pinging in] and see what happens.
I'll be changing it back to the performance tune's stock timing after my tank is completely full of premium.. you might wanna try the same..
Do you have msn or yahoo?

I mean I ran the 93 for a long time I just dont like that if I do run 87 it pings..it just doesnt seem like it should do that..but I guess it could also be the tune.
So what you are saying is take the timing advanced or retarted to the max? and Do you just mean 2% leaner?
I have tried hooking up the xcal2 to my computer but I cant get it to work...I dont know if its vista or what...I would like to hook it up though...
Storlied I dont have either of thoes but I do have aim...vansnxtweek

I have vista and have zero problems, use the latest programs.. you can get them from www.sctflash.com
when you select your tune, it Should ask you if you want to customize the options.. just down the timing in the rpm range you have pinging issues. -1 until it goes away.

What your seeing is that the timing is too far advanced for a lower octane fuel. It's quite normal if your trying to run a high octane tune on 87 gas.
In the user adjustible settings you can make the WOT air/fuel richer or leaner. Mines at 2% under the leanest setting possible. And my timing is maxed. (using a scanguage I see 25 at WOT)

Using the x-cal2 with a laptop will allow you to see knock sensor activity.
I run at least 93 octane, have the timing jacked to the max, and run it 2% below leanest. Never have any problems. I've even tried 92 octane a few times... and noticed it pinging only once.
