Gryphon 1st impressions

jerodr · #1 Fri, December 26th, 2008, 02:24 AM

So I installed my gryphon last night and went out and tested it today. First of all the shifting is awesome! I have been running the canned tunes level 2 the whole time and I could really tell a difference in the truck. I love the way it looks on the dash and all of the guages are very useful. However I was expecting the throttle lag to go away and I don't think it changed at all. My mom has a stock 07 fx2 and the throttle response is much better on hers even. I plan on ordering custom tunes after I purchase an intake so I guess my question is will my throttle response improve with the custom tunes? I am going to try level three on my next tank of gas to see if it is any better. Has anyone else experienced this with their canned tunes? I was honestly expecting it to be like a cable driven throttle so maybe my expectations were too high?

It's been over a year now since I put an Edge, later upgraded to a Gryphon on my truck, so my memory of the change is not as sharp as I'd like. I DO know I felt the throttle lag was reduced considerably, so much so that I felt like it was gone.

Possibly, I was comparing it to a normally aspirated vehicle and was accepting the slight delay necessary for the transmission to downshift (which can't be instantaneous after all). Overall though, I thought I saw a vast improvement, just with the canned tune.

I don't recall that much difference in the lag between canned and custom tunes though. Possibly (probably really), when Bill reads this he'll have some thoughts and he may be able to tweak something. From your sig it looks like you and I have the same truck (except for one year and King Ranch trim), so I'd expect an improvement in the lag with the programmer.

Throttle lag was one of the things that I payed very close attention to and from a dead stop it still takes about the same amount of time to get the truck rolling and the same amount of pedal. I'm sure the custom tunes will solve this problem in the end though.

Ah - I see we're really talking about two different "lags". I was only concerned with the "downshift to pass" lag. I'm literally a "Grandpa"

and I've never felt the urge to stomp the thing pulling away from a dead stop!

Jack, the downshift to pass lag feels good to me. I don't stomp the truck from a dead stop either. I am refering to normal acceleration from stop. When I press the accelerator to go, say from a red light, it still takes the truck around 1 second to respond(prob more like 1/2 second but it feels like an eternity) and actually move. It is identical to the stock tune in this regard. Sorry I hope I am being more concise.

That IS interesting, Jerod. I've never noticed any kind of hesitation in a normal accelerate from a stop. That's really kind of weird! The transmission has to already be in first, and the torque converter is definitely unlocked, so the lag has to be in the engine's response to your throttle. My engine's response seems very "instant".

I'd definitely talk to Bill about this. I'm sure he will have some ideas.

Wonder if anyone else has experienced what you're describing - anybody?
