No, I know you had 25 which is legit because you have alll the suppourting mods, plus race gas. There were 2 others on here that told me 25 degrees, 93 octane...or 94.....

 

And you were supposed to give me a ride in your car....you never did I wanted to see what 300whp in a coablt is like

 

I could give you a ride in my car

 

The PCM will "octane-learn" and it actually only uses values set between high octane and low octane. You can increase it to 50 degrees across the board, see knock at first, and then it will disappear.

On a race tune, I have octane learn disabled by copying the high octane to the low octane table.

 

I'm not so sure about that. It even says on HP Tuners, that the low octane table is the table used in the case of MAF failure. Meaning the car isn't using the MAF sensor, but rather the VE table.

 

wait til you get to see what a 450 whp cobalt is like..... it's coming... and soon....
and I was running pump gas (93 mobil) and 70% meth (on the meth inj of course).... car ran sick like that,, never any knock... except when I let off the gas between 1st and 2nd (and that was only like .5 degrees).... car was beasting... but after seeing so many blow up... I took off most the mods until my motor is finished... then all hell is gonna break loose... just hopefully not the tranny of course..

 

oh yeah and my "octane learn" was zeroed out across the board, but I also did run my full race tune on the street, and never had a problem with about 8000-10000 miles like that.

 

here;s a pic of a run with it.... don't mind the parameter... I "disabled" them to keep some trade secrets

 

33% IDC at 6700 rpm!?!? Mine are at least 72% by then!

 

wrong PID on that.... ,,, that was just a test run setting up the new laptop... I was really at @82% and up with the 60's third hr I hit mid 80's

 

and that was an old log run too... displayed are my new settings... but they weren't used on that run which is why you see some data missing... I might have a newer one let me check

 

better?

 

my o2 sensors were shot for this run (I had run c12 through the car a week before)

 

as you can see 1st gear traction was non existant... lol

 

Looks like you got some knock on there. Also I notice your IAT2 was 135 degrees after only like 5 seconds at WOT.

 

Okay, Now I have two Qs, where is the Commanded AFR and where do you disable the Octane learn, Just tell me the name of the tables!

 

Commanded AFR your going to want to change your PE table EDIT* Engine>Fuel Control>Power Enrich>then go to the one right underneith where it says HOT, its something like PE multiplier. Say your PE multiplyer is at 1.30, then your commanded AFR is roughly 11.3. Here
1.30 = ~11.3
1.29 = ~11.4
1.28 = ~11.5
1.27 = ~11.6
1.26 = ~11.7
1.25 = ~11.8

You disable octane learn by going to: Engine>Spark Control>Timing Advance>High Octane. Then highlight ALL of the cells in the high octane map and hit control>c, then go to the low octane map, highlight all the cells and hit control>v. If you did it right, most of the cells in your low octane map should change into pretty colors. And thats how its done.

 

yeah because that was my 5th or 6th run in a row... and I had just driven an hour and a half in traffic from manhattan before that.... not bad I should say... and also that was the 3rd pass on that log run..

and with PE table it depends on what your stoich afr is at for those multipliers to work correctly.. I know with the Intense tunes they change it from 14.69xxx to 14.7988 or something like that, so your PE commanded would be a bit different if you are modifiying it.

 

and with the knock I was getting it was 2.3 degrees when I shifted for some reason... I think it had something to do with the solid mounts in my car

 

It is used as a default table in certain emmissions related failures.

Log "knock learn factor" as a PID and it will show you how close to your high octane table you're actually running. Values of 1 will be the high octane table value. Values closer to 0 are approaching your low octane table. If you have values of 0.8 for instance, it shows you pushed too much timing and the PCM will be pulling it for that cell regardless of knock detected for a certain period of time.

The PCM moves timing towards the high octane table at a rate 10 times slower than it will learn low values due to knock.

Edit: I can't spell

 

On both my race gas tunes, I have the high octane map copied to the low octane. On my pump gas tune I copied the high octane to the low octane and subtracted 2 degrees from the low octane.

 

OK this is the tune i run for my daily driver (I don't have a weekend tune YET)....You can See my mods my vBGarage:



I'm pretty sure I have pleanty more potential

 

Yep thats about how much timing I run on the pump gas tune. Its no fun, yeah its fast, but with a simple reflash it could be CRAZY fast! I couldn't take it so I flashed my race gas tune on it and threw in several gallons of 101 octane. WOO HOOO!!! 25 DEGREES OF TIMING FTW!!! NO TRACTION IN FIRST OR SECOND FTW!!! Clutch slip FTL
