O ok yea u smart I can learn from u. So question. On wot where do I want my afr to be

 

Roughly right around 11.7 give or take. I find that is a good solid reliable afr. I have been tuning lsj's for awhile now and have learned a lot myself, I am here to spread the knowledge .

 

So what tuning software would u say is the best to get

 

The best program and the program almost everyone uses is called hptuners. It's really amazing software, you can change just about anything you want to.

 

I know what that is. I'm familair with it. How are safc with our cars?

 

Crap.

 

Yeah 2007 stage 2 runs 22* timing. I'm runnin 22* timing with a 2.7 no meth on 91 octane zero knock

 

may not get knock but i bet your iat2 r around 170-180 after a few pulls

 

nope highest I have seen is 160* my afr is 12.0 untill 4500 then dips to 11.8 till redline o and no cooling mods

 

thats pretty good...160 is abit high for my liking but thats actualy pretty good

 

Yeah its higher than I like to but it will have to do for now

 

Incorrect, stage 2 timing is 15 degrees, NOT 22. You might have used hptuners to change it to 22 degrees but from the factory gm stage 2 timing is NOT anywhere close to 22 degrees.

Also running a 2.7 without any cooling mods isn't the best idea. I saw that you said you only hit 160 degree iat2's but I am sure that is with only one hard pull, if you do several back to back pulls they will sky rocket and you will be retarding timing. If you can post a log/scan because I would still put money on it that if you are running 22 degrees of timing on the bottom right hand side of the graph that you are knocking, especially with 91 octane. It's POSSIBLE that your not, but there should be a few cells getting knock. I have tuned a lot of cars and pushed a lot of cars very hard and 22 degrees was the most I was ever able to tune on a car without knock, but that was with some cells as low as 18 degrees.

Anyways, good luck with your car and keep an eye on those iat2's.

 

agreed....might start of 22* of timing but as the graph keeps going wont it pull timing? so at the start u will have 22* but near the end of the pull probably around 16*? plus knock

 

It really just depends on how the tune is set up. I would put money on it that hes knocking and or pulling timing from high iat2's. Most tunes start to pull timing when iat2's are that high. Plus I know hes knocking lol.

 

22* all the way to 7250 also Zach you might want to look at the most recent Gm stage 2 its 22* untouched. I have zero knock. 160 is after about 3 pulls

 

please get a picture of the table...i wanna see this. What mods do u have?

 

the thing is, the table commands 15* of timing but the car holds 22* of timing with zero knock. i dont have access to my laptop right now but i have logs to show it

 

lmao, this thread is awesome.

a stage 2 map does run more than 15 degree's. hi. timing adders/multipliers. do some math.

low timing down low does NOT equal torque. complete opposite actually.

i have cranked 24 degree's into a lsj without meth with ease. just because you can't do it, does not mean it can't be done.

also. flashing peoples cars with maps built by other people does not make you a tuner.

 

ill get a log tomorrow or wednesday...
you people just need to realize that lower pulleys don't always mean bigger #'s.

 

A stage 2 tune CAN run more then 15 degrees of timing yes, but what I was trying to say is in the high octane table alone, the max timing in boost aka the bottom right side of the graph is 15 degrees. With adders and multipliers and all of that jazz it can be increased yes, but the actual high octane map is at 15 degrees and that was what I was trying to tell the op. As far as being able to run 24 degrees of timing on an lsj without meth, I am sure its POSSIBLE but I don't recommend it for the average person adding timing on there car. The MAJORITY of cars can't handle that amount of timing without meth, especially in all of the cells. As far as flashing cars with OTHER peoples tunes, that's a little bit off there Bryan, all of my tunes are done from scratch when I go out and tune a car, the only time I send someone a file that is already done is when I sell it and send it via email. Other then that I always tune every car straight from scratch, hence why it takes some time. No one has ever complained about my tunes and I always have satisfied customers, I may not be the most knowledgeable tuner, but I know enough to be able to make my customers happy and that's all I care about.

 

log snap from awhile ago

basically only timing messed with didn't have my wideband. have that now so yeah once i get un-lazy.

 

Nice, ya I wasn't saying a car couldn't do it without meth, I just personally don't recommend it. But then again if you aren't seeing knock then there is no harm. The op doesn't really sound like he knows what hes doing with timing and if he just randomly tosses in 22 degrees he WILL have knock, especially with adders.

PS: Your injectors are maxed =P

 

ya lol i wouldn't reccommend it for everyone. I know i slammed off the limiter one time in first cause i always can never time that right and my car choked and cut out bc of the higher timing and rev limiter slam.

haha yeah it's just running too rich is all i'll fix that soon hopefully .

 

Stop the spread of misinformation. I haven't said anything til today, but you need to go back to the drawing board

Here here!! I <3 you Brian

 

I just assumed he knew how to figure out what kind of timing stage 2 was running. Guess that explains how you can blow up with 2.8 full cooling mods. I'm no hero I figure out new stuff every day but maybe know what you are doing a bit before you advertise and travel around tuning these cars
