this is probably a noob question but id like to know because with the next year or so id like to program my truck...probably with a gryphon

anyway it seems like the standard for custom tunes are

1. Towing
2. Fuel Economy
3. Performance

i have a friend with a 97 5.4 auto w/ the gryphon and it seems to me that the shift points in each mode are very different.

So I guess my questions are,

Are the majority of the gains seen with programmers from improved shift points?

And since I have a manual would i see less gains than an auto?

Thanks in advance

 

If it was only shift points, you'd be wasting your money. There's many other parameters at play here, and this is what I've inferred by reading what people who tune, post about tuning:

The fueling map is changed. This means the amount of fuel delivered can be varied according to airflow, rpm and engine load.

The timing map can be changed to optimize spark timing at a given load and rpm.

The RPM limiter and speed limiter can be changed.

Possibly, the valve timing can be changed? I'm not at all certain of this one though, but with hydraulic lifters? If I'm wrong on this, just forget I said it.

So, I think a programmer can help anyone!

the tuner cannot change the hydraulic lifters timing

it can change the fuel map, spark, etc



you would probably see more gains since you don't lose as much power thru the trans as the auto guys do


there are many chipped manual trans vehicles, I had a chip in my old V-10 stick shift truck

 

I thought I might have been way out in left field on that, so thanks! I'm always happy to learn. I was just trying to think of things that were possibly controlled by the PCM.

My reasoning went something like: If it's hydraulically actuated, then there are valves that control the process and these things could have properties that can be modified electrically. So, I took a chance.

Hmm..cool

I havent really done much reasearch on tuners yet, but im considering gettting one around the end of summer.

My poor v6 needs all the help it can get when i try to pass little ricers on the freeway lol

 

Jack, I've heard the VTC engines can be controlled a bit by the tuner but that's a whole 'nother can of worms



blackedoutv6, your truck tuned for performance with 93 octane, with e-fans will do allright


but I need to know what gears you have???

 

mm i honestly dont know...ill run out in a little bit and check the tag on the rear end, i know its an open diff, and i wouldnt mind changing that too lol

i feel kinda bad for my truck cus ive kind of neglected the performance side of it lol.

 

what's your axle code? it's on the door tag

 

sorry things have been busy lately and i forgot about my own thread lol

my axle code is 19

 

thats 3.55 non-LS

so do you have the M5OD? your siggy says 4spd?

if so, you and I both have the same identical drive/powertrain. i'd imagine you would win in a race, you are a few lbs lighter.

 

yeah i knew it wasnt LS, which sucks, i hate one wheel peel

im not sure what tranny i have

my trucks manual, so 4 gears+overdrive

today i pwned a 03 scsb 4.2 manual on harley 20s twice from a dead stop
had at least 2-3 carlengths in about a 1/8 of a mile

 

well that OD is counted as 5th, so you have a Manual, 5 gears, with OD, hence "M5OD" I could be mistaken, but the "M" might also stand for Mazda, who built our trannies

 

aaaaaaahhhhhhhhhhhhhh it all becomes clear now lol
makes sense, ive just never really researched performance stuff for my truck

thanks man, learn somethin new everyday

 

 

Performance is all you need to know. Some guys will tell you to lift the truck 12 feet in the air but really now, everyone should spend that money on blowers and turbos! It saves rubber trees and makes the world a better place.
