LS1edit questions
i have 2000 LS1 camaro and i want to tune it using wide band O2 sensor.
any one knows how to tune using LS1edit what tables i use to tune the A/F ratio anf what is the effect of adding/subtracting a digit in that table affects the A/F ratio?
also how about the timing? how far i can go with timing advance before causing knock? for NA or forced induction turbo/supercharger. the one i have will be NA.
how is the stock timing table? is it realy good for NA motor and you don't need to touch it?
thanks

With the wideband sensor data, adjust the primary and secondary ve tables. The idea is to put the car in speed density(SD) and set the Open Loop Fueling to 1.000 and tweak the ve table to acheive 12.8-13.2 in all cells. If the wideband number is less than 13, you need to decrease the VE and vice versa. I am still using my stock timing table and runs great. I run 28* at WOT and no need to go higher. What scanning software are you using? LS1 Edit is outdated and HP Tuners offers a trade in credit for LS1 Edit. I traded mine in and got $150 off of HP Tuners. HP Tuners v2.0 make tuning so easy and uses one cable for scanning and editing.

Stock timing table here except for extra timing at low rpms for idle.
With Edit, I've found adjusting the PE vs RPM table one percentage point is about two percentage points for a/f. With my setup, x90% gives an a/f of 12.8-13:1. I'm currently at x89% which gets me about 13-13.2:1.

i want to tune the car while it is at stop ( not on a dyno i.e. the transmission is in N position) i mean while the car is not moving. i read once that with the car not moving if you get an A/F ratio 0.5 less than if it is moving so i have to adjust 0.5 A/F ratio less to get the excat A/F ratio when moving on the road. that is while at stop if you get 12.5 A/F ratio you get 13.0 A/F ratio while moving on the road.
