Truck has alot more top end response & shifts better!! This is the NEW TUNE & a LOG:

LS1BKyle_Modded_New Tune.ctz
LS1B_Kyle_NewTune.efi

Any other suggestions or tips?? Loving the improvements!!

[kylelavergne]

I meant B3608 to zero, and dropping Hot and Normal PE mode enable to 70%. ok seriously leaving. lol later

What tables would this be?

[bmd2_colo]

you changed them already. My bad on the typos. Glad to hear it is working mo betta. I haven't checked out your log yet, gimme a min to check it out

[bmd2_colo]

looks like it isn't knockin TOO bad. Might want to pull a deg or two where it is knocking in the upper MAP areas.

[bmd2_colo]

Gettin it to launch hard off the line will be a bit more involving, I think. Stock converter, heavy truck, etc. Could try messing with the REV limiter (although I personally think that is a bad idea on a truck, maybe not a vette), maybe changing the trans RPM shift levels (like which RPM is the point where it goes from 1st to , 2nd to 3rd, etc). Gettin the engine up into high RPM as fast as possible where it likes to run could help a lot. Just make sure you have a clean backup copy so if you mess something up you can reflash if you forget what changes screwed whatever up. The CalcVET thread is great, maybe run a CALC_VET session on your truck some time.

I know you're trying to get it to run hard and fast but goin full boogey on the HD isn't the best thing for the trans, etc. You know all of this tho. I don't really tune my trucks for launching hard and stuff, so maybe someone else can help you out with that stuff. Ask away about CALC_VET, took me a minute or two to get it set up so don't get frustrated.

How do i tell what areas to pull from?

I have all my WOT rev limits set high. wanna say like 5900 RPM. Rev Limiter is off. I saved my origional tune as a back up. lol. How do i do the CALC_VET? Never heard of it.

[joecar]

B0120: set to 4000 rpm.
B3616: set to 65% below 3200 rpm, 35% above 3200 rpm.
B4206: set to stock (131*F above 50*F).

D0960,1,2: set to 100% everywhere.
D0701,2,3: increase pressure early (eliminate the flat spot down low).

TCC Apply/Release tables:
you have the tables "upside-down"...
you must observe these rules:
3rd release < 3rd apply
4th release < 4th apply

Calc.VET procedure, see post #1 here: Calc-VET-correcting-MAF-and-calculating-VE-(in-single-log)

[bmd2_colo]

The numbers in the lower right area of the table are where the computer is pulling x amount of degrees of spark advance because of knock. Go into your Spark High and low tables and minus the amount that the computer is pulling from the table above in those cells. e.g. 4400 rpm 90 kPA MAP pull 3 degress from that cell in your hi/lo tables. Blend the values with the surround cells.
