Boosted tune questions.................
Boosted tune questions................. I'm new to EfiLive V1, and thought that I'd try to tune my new A&A Vortech setup on my 2001 C5.
I was told that the timing table from a 2000 Camaro was a Very good place to start (Thanks Jesse
), but I'm a little confused about the VE table and boost. Can I AutoVe it with a wb02 (haven't decided between an LC1, WB Commander, or a PLX SM-AFR) and get it or will it have to be dynoed?
What, other than IFR (calculated using Redhardsupras spreadsheet. Thanks RHS) do I have to do to tune with the 60 lbs. Mototrons? I've read the stickies and everything that I can find on this, but hopefully I can do it myself and learn more about my car.
I Apppreciate any help you'd be able to give me!
Thanks in advance!

As far as fuel system, I have the stock fuel system with a RaceTronix pump and harness, and a KB BAP that comes on at 3 lbs. boost. The injectors will be 60 lbs. MotoTrons in place of the stockers.
I was told by Andy of A&A that a fuel pump would be plenty, but I thought that a BAP can't hurt and I'd like to do this only once.
He sent a 3.6" pulley (I'd guess 9-10 lbs. of boost, but I don't know for sure).

Thanks Guys for your help!

Should I back it down a few degrees? It's probably better to add timing, and watch for kr than it is to take it out huh?
and of course, not blowing things up is a good thing

yah I would start with about 15 degrees of timing.

get a real fuel pressure regulator, soemthing you can reference to the manifold, it's the only way to keep enough fuel pressure to keep injectors supplied with right amount of fuel. also, the ever popular walbro supplies 255L/hr of fuel, which is enough to supply 8 ~50lb/hr injectors. you're gonna need bigger injectors to do FI on a big v8, thus single walbro just not gonna cut it. read my recent blogs about it, it's kinda scary.
yes, start from the safe side, you dont want too much timing induced knock because it will screw with your AFR which will not converge on a solid VE.

Who makes a good regulator that won't break the bank?
I'm off to read your blogs now.
Thank You!

Also, if you dont use a custom os, I use the table B5908 to do the pulling for me. If i set that table to pull 4 degrees at my commanded pe value. Then any time im in PE it will pull out the timing and make it not have any kr. It will have plenty of timing for regular driving and wont be sloppy or have any hesitation that way from lack of timing. 
Just a little cheater hint for you.

Thank You for correcting me!I wrote the wrong year down. Got a case of Sometimers! It's like Alzheimers, but only sometimes!

Sorry again for the misinformation! That was my fault (not Jesse's) and I just went and cleaned out my ears!
