For those that have been following and/or doing these Trifecta tunes for your 2.2L, is there anyone, like myself, who would like a tune on a stock 2.2L for the potential increase in gas mileage only?

I emailed Vince and asked the question. He said that he hasn't really evaluated a stock 2.2L to see if only a gas mileage increase could be done, or that on a tune it would be beneficial enough to do so.

He needs a local 2.2L owner to do some evaluations on to find out.

Hopefully others...local others , are thinking the same thing and someone does the duty of letting him test out a mpg increase tune on their car.

Waiting patiently...

not sure how much can be done.

I get better gas mileage on my tune now.

38 hwy is a hell of a deal

Yeah, he said the car has a 14.7:1 a/f ratio during normal driving that can't be changed, but he was still open to the idea that an increase in mileage can be had...only needs a test car.

Mine is an auto and is already getting that on the hwy...last trip I took was a hair under 200 miles(one way) and the econ stopped at 37.3 by our destinations end. It was still rising, just alot slower, naturally.

So when does this 14.7 AFR change, cause I have the tune and it never seems to drop off according to my dashHawk. I guess commanded is different than actual though.

i got fully tuned and i love it my ls is pretty strong now

copson20

with the tune the afr should drop to 13.3 at full open throttle

Installer1

Not sure, I already deleted his email but he said in normal economy driving, which I would assume is less than part throttle, it remains at 14.7:1 and it can't be changed. He did say the timing could possibly be tinkered with to make an increase in mileage, but still needed a test car to confirm.

I wonder if a normal piggy back mapping system and a laptop could do the fuel curves?

His address is: vince@trifectaperformance.com

What year LS do you have?

gtxsport11

2006 and it is modded

FutureEcotecOwner

Ever been to the track? I'm in the process of getting an Ecotec powered car and I rather get an 07 or 08, but cant stand the fact of no cams, so I'm thinking 06 is my year.

gtxsport11

no it has not seen the track yet
whats bad is i have had it for almost 2 years and have modded the **** out of it
i am bout to get a 50 shot on NOS also so as soon as i do that and get my new catback i will take it to the local dragstip and post up some numbers i am also putting it on the dyno here soon

FutureEcotecOwner

Do you have more mods than what your sig says?

gtxsport11

no except for the new magnaflow catback and the nos and the turbo kit that i have just laying around waitin to be installed i just ant had time to work on it

FutureEcotecOwner

Very nice, get that **** installed and go tear up the track!!

gtxsport11

ok bro you bet
only one prob i am trying to sell my balt and buy a 05 SS SC that is bad as hell

FutureEcotecOwner

I'm taking its already modded?

gtxsport11

yes quite a bit it is on here is name is playswithcars
i am located in statesville NC and if you anybody that want a modded ls for 14K hit me up

lil_kano

lol. dude i already told you, command AFR means what the car is trying to stay close to. Its not a wideband...

FutureEcotecOwner

Yeah I'm not sure anybody I know around here would wanna travel that far, LOL.

well i finally got it, car is commanding 12.8 AFR and dropping close to redline, which is good. The tune is worth it guys. No one has disliked it yet

Tune is VERY worth it.
if anybody has anything that vince needs to test, let me know...
i was and am the test car and my girl has an auto 2.2 so we can test on that too...
im going to be doing cams, intake mani and tb soon...so testing for those in person...
just let vince know you need it tested and pm me if you think it needs to be teste din person so i can talk with vince

What you just said is the basis of my initial post. Im interested in economy only with my 2.2L auto. He said that he would need a stock 2.2L to play around with to see if a tune can be made for the sole purpose of increasing gas mileage. It would collaterally have to be a slight performance tune, seeing that the only real way to increase the mileage per gallon would be to fool around with timing and the AFR/fuel curves, i.e. leaning the mixture out some.

I could care less about rev limits and speed limits and the transmission shift points, etc.

Increase my MPG only.

If you were willing to let him do some tests with your girls 2.2L auto (hopefully it's stock) to see if he can boost the economy, that would uber rule!

yup, hers is BONE stock performance wise...and mine is not so stock :P
just so you know, hers is tuned right now as stock and it did increase her gas milage from around 30 to around 36 per gallon..i drive hers alot and we have been watching this.
Contact Vince and let him know that you would like this tested and that you spoke with me and then him and i can get together sometime

do you know by chance if vince has tried to tune a 2.2l for a supercharger? If so how did it work out?
