The original map was filled with AFR ratios of all different ratios ranging from about 8:1 in the upper left to 14:1 through other areas. It varied wildly through out the map. My question is, Now that I have taken the chart and tuned it all to 14.7:1(except the last couple columns) Would it even run being so lean? I mean, it is idling at about 10.5-11:1 with my wideband the way the stock map is. This is almost exactly what is commanded. It runs good in 1 bar, but real rich. It also will not idle untill warmed up. I am just afraid that I will have major tuning problems with a 14.7:1 ratio through the entire map, when the "stock" map varied through out the map like It seems like it should. Should I use the stock map and lean it out? Thoughts?
Any unput or experience on this? Did yours run decent?
The only mods besides the turbos, are turbo headers, a comp .581 lift cam with 224 duration, and a lowerd (8:1) compression ratio. Any input?
