Detonation with K&N and XCal 2...

You CAN adjust timing with an XCal 2 using Xtreme Tune IF the dealer gives you the tune via email or on disk (we do). If the dealer uses SCT's latest dealer software (we do) than the dealer can allow on device ajustments without a computer or laptop. You can't add much timing, but you can pull a lot of timing.

The XCal 2 will allow the afrementioned user adjustability, as well as datalogging with a laptop (soon to be on-device), the ability to read and clear DTC's.

Some dealers can further customize the tunes on your XCal 2 via email - it goes like this - you datalog what the dealer tells you to log, then you email the dealer the log, then the dealer makes changes and emails you an updated file. I do this all the time for my customers - it's not required for dealers to do this, but I do it. You can get really close to dyno results for idle and part throttle with this method. If you have a wide band (we require one for a mail order with a blower/turbo) than you can even get WOT pretty darn close. It takes patience and the desire to take the time to do the datalogging.

From what we have seen, the CAIs usually lean things out quite a bit, my guess is that's what the culprit is. The other thing, I doubt it's detonation free revving it it under 1000 - there just isn't enough load to do that - the detonation on shifting IS a problem though and that's easy enough for your dealer to fix even without any datalogs.

Hope this helps,

Don
