I think Eric normally writes the timing on the chip tag...if there is any doubt, drop him a note with the chip number and your name so he can look it up...but, pretty sure he uses the same settings on most of the chips he does
If you have powerlogger, you can look at the timing graph and see for yourself
-
Erics alky chip WOT default timing is 20.5 degrees on PL.
-
pretty sure it is normally 23 in 1/2 and 21 in 3/4 by design but I don't know what the non alky version is...pretty sure a search of his board will give that answer but I would just look on the chip label
and yeah, I think I have seen 20.5 on the pl dump
-
Steve, I'm seeing 23 degrees in 1st/2nd on PL with my alky chip. Eric always labels his chips.
-
Ive got one here says 20-18deg 16-18psi 93oct
-
from my reading, if I stick with this chip, it sounds like the smart thing to do is leave timing alone, get fuel numbers in the 780 range with boost at my goal setting of 22-23LBS, then move timing toward the 23/21 range watching for knock?
-
I might look for a bit lower on the o2s, but it will work
-
A chip that's burned for exactly what you wanna do is cheap insurance. Just my 2 cents.
-
yep
-
I descided just getting a new alky chip was best idea, as soon as I find out the stall of my converter I can order it. better safe than sorry
-
don't think you really need the stall for this purpose, but put the car in drive, foot on the brake, mash down on the gas until the car starts to move in spite of the brakes being on and look at the sm to see what rpm that is..use that for the stall
-
The place that did my tranny rebuild told me its a 2000 stall? That dosent seem correct to me, if i remember right when I test/tune, the car overcomes the brakes about 2700/2800.
Stupid question time. I'm going to check it tonight. You say "mash down on the gas"..... so quickly step into it or ease into it while watching the rpm on the SM. Or dosent it make a difference? Also is it the rpm when " the car actually moves" or when it starts to "lean into the brakes"
Thanks!!
-
when it starts to turn the tire against the brakes. I normally ease into it so I don't run over something
-
What will make a difference is if you have a LU or NLU convertor. If you have a LU convertor Eric can have it lock for you at a predetermined MPH in 3rd gear at WOT for racing.
