Question about tuning with alky

[IronCityTurbo6]

I have Razor's kit and a Turbo Tweak alky chip.

I do not have a wideband or pyrometer as of yet, so my scanmaster readings are all I can go by.

My O2#s are in the low 800s, and I'm seening as much as 3 degrees of KR.

Is this a rich knock?

If so, to lower the 02s should I be taking out alky or taking fuel out of the chip? It seems to me I would want more alky than 93 octane pump gas.

When should I start to add timing, and how much?

The boost is at 24

The timing is stock (for the chip 23/24)

I took 10% of fuel out of 1st gear (lowered my 60 4 tenths)

At what MPH are you seeing the knock?

There is a huge difference between 3 degree's at 15 MPH and 3 degree's at 120 MPH.


Low 800's is fine. You have to start somewhere. Now dont advance timing until you have the knock squared away if in fact it is a problem.

dom the default timing is 23/21 not 23/24 just dont want you to get confused while tuning 23 first and second and 21 third and fourth. never pull alky just fuel. alky is to quench knock

dom you might want to try running without the voltbooster. might be spraying to much

Knock is coming on the 1-2 shift then going away, middle of second gear then goes away (never looked at speedo, too much other stuff to look at), then 2-3 shift and goes away none in third gear through the traps

when I say "goes away" I mean in a second or two.

Thats a good point I'm gonna take it off and see how it does.





How much fuel should I pull from the chip and how much alky should I add?

Im at stock settings in the chip (except first gear -10%)
Alky is on 5

i wouldnt pull fuel till you are at a comfortable boost and timing range. that is for tweaking. your chip should be close at the fueling. i would set the alky at 5.5 to 6 and see if you get the knock to go away if it doesnt i would suspect false knock from shifting. might want to check mounts and clearances of tranny lines and uni. joints. again to little turbos love high timing and big turbos love low timing

Real knock escalates 1, 3,5, 7, ........ False knock comes 6, 3, 1, 0....

No amount of alcohol can fix false knock.. like motor mount, bad transmission, TQ converter, exhuast banging the frame.. etc etc etc

Everyone see's knock on the scanmaster and panic's.. you need to step back and ascertain your situation.. and make decisions. You need to control your environment when it comes to tuning.. making WOT pulls from a dead stop when your troubleshooting knock.. is the absolute worse thing you can do. Make 2nd gear or 3rd gear runs.. no shifting.. and watch your scantool.

I get this call on a daily basis on "KNOCK"... any metalic sound coming from the engine sets off the knock detector.. you need to minimize engine rocking back and forth.

Aside from that.. lpaulabbot.. rite on..

I just looked at my chip again it is 24/23. Maybe Eric can back me up on this chip#3210.


Thanks for the input. I really want this car to go 11s with this combo.

thanks julio. b.t.w. is was very nice meeting you at bowling green. i was with bryan wanner.

dom that may be with the timing but i never saw that for timing especially with 3rd and fourth higher than 1st and 2nd. but there is always a first. probably a typo on the chip. he does do thousands

As the heat goes up.. its going to get tougher. You need to get the 60 foot on the car down to the 1.6 range. And get the MPH up to 110.

I dont doubt the chip, Eric sets timing based on what information he gets from you when the chip is made.

Try locking the converter, get more aggressive on the launch.. bump up the 1/2 timing.. get the 330 down at the track.

Thanks guys


Just ordered GM Performance long wheel studs, slicks are on the way!!!!
