Hehe, yeah I figured that a "Fresh Meat" post would lure the Mintaur out while we all get to feast on some juicy information. ^....hey, sounds lame now but I guarantee it seemed pretty good when I typed it the first time. Any other secrets about the tunes in reguards to drive cycles and emission? (...or like which button combination to push to make jet engines come up and light for some extra passing power?)

Back to another question for the Mad Doc, (if he sees this).
Since timing can be "corrected" (I won't use the term "controlled", because that's not how I see things working) by the knock sensors, what is the danger in overadvancing the timing? I get the feeling it's not a "cure-all" for sloppy timing adjustment. But, why not? - Jack |

The reason it's best to use the knock sensor as an "emergency relief valve", so to speak, is that when the knock sensors detects detonation the PCM pulls out a HUGE amount of timing in one shot to protect the engine. This will have a significant impact on performance and economy. It is much better to go with a slightly less aggressive curve that doesn't cause detonation than it is to push the limits.
One other thing to consider is that some of the earlier engines DON'T have a knock sensor to compensate for sloppy timing curves. Obviously, things can go wrong quite quickly in this type of situation.

Thank you sir! Makes perfect sense.
I asked, because again, some people on f150online have suggested it's "no big deal" if the timing is overadvanced, since the PCM will just pull timing if knock is detected. Didn't seem like a good approach to me, but I couldn't say why. - Jack |

I'll just throw this in for you guys to chew on also.
With the Harley tuning software you can turn off the knock sensors. You can also turn off the heat management system. Some bike tuners will often use these in the off position when tuning a bike on a dyno for more "true" readings. But when done they turn them back on. Sometimes they forget.

You want to know something funny? I've seen gas tunes from prominent tuning companies that have the knock sensor offsets set to 0 degrees adjustment. Yes, that's right... ZERO! Even worse? This was on SUPERCHARGED vehicles. I guess there isn't any need to have the knock sensors functioning on a supercharged application. What do I know.

Haha wow, I remember 88Racing once asked me if I liked playing with fire. But compared to some of these guys I was messing with water pistols.
I sure hope these guys aren't letting the knock sensor control their timing.

Good Lord! Nothing like giving your truck to a bunch of chimpanzees to tune, eh?
It's funny, I only bought an Edge after reading a LOT of talk about it on another forum, all positive, and after noticing how you, Bill, were always jumping in and helping people with any problems. And, when I got it, you can bet I was VERY careful how I drove the truck until I was totally satisfied that nothing was amiss. I sure didn't run right out and "stand on it" right after loading a tune, and, if any of the "Custom Options" didn't feel quite right, I'd immediately return to the programmed value. (I also worked with "small" changes, one at a time). I didn't even consider upgrading to a Gryphon until I'd seen a lot more of you on that forum and had talked to you on the phone. I only made the jump when I became convinced you knew what you were doing and felt reasonably confident you weren't going to blow up my truck. - Jack |
