Trottle Delay

[cajunboy2208]

There is a good 1/2-3/4 second delay in my throttle response.
Drove my friends 07 4.6 yesterday and noticed that you just barely touch his throttle and his goes. Mine, you gotta wait a little bit. Even when flooring it.
Thought all of the trucks were like that, but apparently not.
Anything I can do to make the delay go away.
Anything that I can edit on the gryphon either?

Bill is the only one that would be able to adjust the throttle delay. Also, sometimes if you somewhat ease into the higher throttle rather than go from cruise to floor you will get better results. I dont mean a regular acceleration but if you give a bit more time to adjust you might get an overall quicker response.

I know I've gotten my best 1/4 mile times by not planting the pedal on the floor from 0-90. Instead keep the throttle heavy but know when it needs to let off, like for shifting. Even then I still ease into the throttle positions.

Wait, you can't mean use - "judgment" and "intelligence" can you? Gosh, you might even have to understand what you're doing here!

Intelligence? Judgment? Understanding?!? What are these traits you speak of Jack? Lets play a little game for the true answer. What's another name for an educated guess? Give ya a hint, my screen name minus 270. That is what it is. Ex. It was originally a ________ that has been working out since.

Unfortunately, I did my yearly quarter mile times tonight and I was "off" so planting it did have better results. First time to have the tires squealing on a dry start though. Maybe that is why my 1/4 mile was .2 sec behind what I expected since the first few runs with the larger tires. 16.7s with horrible reaction times(but I'm not sure if that counts on the overall time for the gryphon). I probably would have gotten closer to my goal if the tires had stuck and if I was on a smoother road though.


Cajun, dont worry, I'm sure 'ol Jack is picking on me. I went out knowing I haven't been having a good week coordination wise. Without being carefull I did have some lag. What year is your truck and are you running stock, Bill's custom tunes or stock gryphon tunes? Also if you are using a tune you "edited", did you advance the timing and stuff? If so, to what "comparative" values? I remember a little while back you were asking about timing advancement, shift points and such. I want to see if or how it MAY be involved.

CAI, and catback exhaust, with a 87 custom tuned gryphon
But since the 87 custom tune is not faster than the 93 canned tune, I am in the process of editing the 87 custom to my standards.
Right now I only advanced timing to 1.5, of course using 93 gas.
Tomorrow I will be advancing it to 2 and maybe mess with the spark

One question, if I am editing the custom tune, the other values of the custom tune will be the same correct?
I m asking this because when I have the 87 custom tune loaded, it idles at around 600-650.
But when I edit the custom tune, it is not at 500 idle

Spark and timing advancement is the same thing. It is also something you need to pay attention to when you are making adjustments.

You could transfer settings but I personally wouldn't. You can't know for sure where Bill has your timing and stuff set. Instead, do what 88racing and I do. We have hard copies of changes we make that are on paper. When we make changes we can go through the list and know we didn't miss anything. These changes only apply to that tune though, a different tune will probably have different settings. Then you drive and tweak the tune (writing down your changes AS you make them) and when you are happy with it you have the hardcopy you can go back to.

As for the idle I'm not sure how you can fix it. Does the same for me and I've never been able to fix it even with the idle adjustment setting. I think that only makes the idle higher for underdrive pulley kits.

Good luck!
I would rather goto the master and have him change it then to do what you're doing.
Maybe there's a reason why he wrote your tune the way he did............
