Hello,
I have read a lot of threads on tuning and still have a ton to go, but I am in hope that someone could do a flyby look at my tune to see if it is close enough for me to start the motor.
GTO Speed Density 2 SD enhanced and TCS patch 2.hpt
It is a 2006 GTO LS2
CNC ported LS3 heads, stock LS3 intake, no MAF sensor
Deatschwerks 50lb injectors. Deatschwerks DW65C fuel pump in stock tank
Fairly large cam: 245/253 .650/.650 110
SRP forged pistons and Manley H-beam rods. 10.2 to 1 compression.
ARH 1.875 headers, 3" catless mids. 3" Magnaflow exhaust.
Daytona WEGO 3 wideband
The motor was on a Superflow 902 engine dyno and made 572/515 if that makes a difference (running with BigStuff 3 fuel injection).
I realize that I have a big undertaking with this project...learning tuning/HPtuners and starting with an SDOL tune, but I'll get there, just want to see if I'm in the ballpark to start the car.
Mods I have done to the tune:
Main VE table: multiplied by 1.15 everywhere. In the 400-1200 rpm rows, I reduced significantly based on what I have read.
Copied stock HO spark table to LO. Set idle at 1400 rpm...will reduce it a couple hundred when I get the basic tune ironed out.
Did the 2 bar SD enhancement, changed MAP sensor values back to match my 1 bar OEM Map sensor.
I believe I have everything filled out so it will stay out of closed loop.
DFCO is disabled
Injector flow rate and related values were provided by Deatschwerks (see attached excel). I used these values except for the Flow rate which I calculated with the Excel spreadsheet on this site.
I'm sure I'm forgetting other changes I made, but am I in the neighborhood to start the car?
Thanks for any help.
Tim
