Help tunning with lc-1
Tommorow I start on my journey to tune using lc-1 wideband. How will this differ from tuning with nb. I am having a hard time bringing in the upper end of the VE table and was advised that friends don't let friends tune boosted engines with nb sensor, So i took the advice and am installing wb sensor. Now can someone point me in a starting direction. Do I work on the VE tables or the AFR tables. Attached is the MSQ. should any changes be made?GM 3.1 boosted 6-8 lbs gm 7 pin hei MS II V.2.36

Here's the basic idea. I'm not sure how you did anything with the NB but with the WB, you can very accurately tune your idle, cruise and WOT areas, and all the areas in between. That is a HUGE difference over the nb. I'm assuming you have the WB hooked up to megasquirt? If so, make sure you modify the configuration to utilize the WB first, then, set up an AFR table with your target ratios for all the load ranges.
From there, with EGO correction turned off you want to start tuning to meet these targets. The first few times its worth while to datalog and use something like the VE analyzer in MegaLogViewer to get you in the ballpark. From there, its fine tuning to hit your targets as close as you can. Then turn on the EGO correction for closed loop adjustments and you're well on your way to a good tune ;-) Should get you in the right area.
