I never saw a large improvement if even a noticeable one. I don't drive the car very often my GF does but she agrees. I even played with running my AFR at 15.0. The only way I can see it getting any better is using the Wideband and tuning VE's and MAF of AFR error so that's why i say it would take a lot of time.

If you notice an improvement after Tyler gets everything setup let me know. I'd be willing to do some work for others I just don't want to waste anyone's money by telling them I can do something I'm not confident will happen. Our STFT and LTFT react so fast to fueling changes that I don't know how much it will help.

 

I'll do as much as I can on the first go... but let me know how the car changes after.... I may have to tweak it again at a later date. I'll explain more when I get into the city.

Saturday afternoon until Sunday afternoon.

Possibly. It would be more of a mileage tune though... you can't do a large amount for power on the stock injectors on an LSJ.

I learned from Power Commander tuning on sportbikes that the fuel alone doesn't do a whole lot for power and mileage.

 

All your efficiecncy at cruise for mileage is going to come from your timing tables. Already I have made a def. difference in mine, its not rocket science, you just balance timing vs. load and watch a few other parameters to adjust in the pockets you need and voila better mileage, however, your not going to see 10mpg increase while setting the cruise. Typically on cruise and letting it drive for you I feel confident you can gain and easy 3-4 mpg.
My last trip back from edmonton w/ cruise set to 115km/h got me 44.3mpg in a slight (very small) head wind. The car is rated for 41mpg at 100km/h.

 

Actually Tyler,

I recall beating up on a stage 2 balt with my stock injectors in pretty good.... hey rippin07

I totally forgot about the timing end of it.... again mr. knowitall has to jump in here. Found max mpg was around 38 to 39 advance. I'll try to get my MPG pid working correctly in HP Tuners so we can actually see a difference in real time.

 

oh snap

 

Haha, you're not kidding!

 

Pure luck.

Although you did successfully run a stage 2 pulley on stock injectors... I will not risk it with anyone I tune.... just preference. If your pullied, get injectors or GTFO!

YAR!!!!

 

And i just happen to have some 42# injectors for sale!

 

I thought you sold those already.

 

i get shitty fuel milage like 9.2/100km

 

Three factors result in good economy; tuning, driving habits, and rolling resistance.
I haven't fully extended any of the above and I still see 5.6-5.8 L/100km.
My little journey into S'toon this weekend should see a few more improvements on that number.... the last time I tired to set a new personal record, I was at 4.8L/100km from Hafford to North Battleford.

 

so did i!! haha

 

Nope. They are in the car right now until the 62# pound disc injectors go in.

 

**** 5.6 i would cry i would love that **** any lose of hp or accel>?

 

I average 8.8L/100km with a heavy foot and average highway speed of 125-130. I'm not going to complain. But once the warranty is up, i will likely be looking for a tune.
I have done a "light foot" mode and made 6.7 L/100km on ST II... impressive, but i feel sad driving at 110 and not passing people. And doing the actual posted speed limit everywhere.

On a side note, i increased my recorded top speed to 237kph last weekend. Up from 230. Then i ran into traffic. Its hard to get the right conditions to do a top speed run... I'll get a pic of my GPS when i get home.

 

good stuff i wanna get diffrent boost gauge i dont like the factory one i dont want kpa or whatever i want psi

my bro took my car out one day just stole the keys and stole my car he said him and his friend got to 240ish stock hes a retard i was so pissed off when i woke up and my car was gone

you guys should turn on the speed channel cobalt is in 1st place in sport tuner class show called KONI challenge series

Tyler arent you on 60# injectors??? If you are how the hell are you figuring out your mileage?? not from your DIC because that is no longer correct. If you found a way to make that correct you have to let me know becuase I have playes with mine and nope, its about .5 to .75 liters/100kmh off. I have flow matched 62s with flow rates from -30kpa to +115kpa documented and there is no way I can make the DIC correct due to running out of IFR table.
I have to do the old fashioned filler up and calculate mileage. Let me know if you found a way to make this correct.

OH, Raptors you want a snap back,,,???? sure, You beat a stage 2 car with stock injectors,......
.................................................. .... BUT WHO HAS THEIR ORIGINAL ENGINE???

 

I would be an only child if that happened to me

 

hahaha i know man but he much old and stronger than me its cool tho now i know what top speed of my car is hahahaha

hahaha i know man but he much old and stronger than me its cool tho now i know what top speed of my car is hahahaha he on oil rigs right now i think i might be goin up there next summer get some mad cash

 

i hit 260 in mine. Atleast that's what my Friends brother's sisters boyfriends uncles nephew told me.

 

Last night at 1 am I drove from Humboldt to Saskatoon in 25 min. Needle buried most the way, used 1/2 tank of fuel. Fun yes, smart no.

 

so what does the needle bury at in a redline

 

thats a **** road too

 

220km/h

BUT WHO HAS A SHINEY NEW LONGBLOCK MOTOR!!!?? AHA! you know you'll never win.....

 

TUNED!!!

It was interesting. Hopefully Tyler's blood pressure has gone back to normal, lol.
