Lots of progress is being made ladies and gents. Iamanonymous has his f22b with a 14b and the zeitronix wideband all hooked up and logging runs. So far we've got a practically straight a/f curve with no spikes of lean or rich, everything is smooth, there are no hiccups reported. And we're getting around a 11.4-12.1ish in the important areas of the map. 2k-3k is still a bit lean but we're working on it. We started off with a stock ls map with my boost columns was all and things are going quite well. Peak tq seems to be around 5000-5150rpm and the a/f at that point is now 11.9ish. We're shooting for a flat 11.5 or so across the board. So yea the f22b is a stroked LS motor as i suspected. Stay tuned folks ...

update.. good progress..
well i started talking to IAM again and damnit.. he made me catch the tuning bug.. so.. after a good nights worth of talking we came up with something.. the LS ignition map is too laid back and conservative (my believe is whats causing his lag in 3rd gear that he feels) so i came up with a solution.. i love the p06 ignition tables myself.. just how their setup is perfect and proves so with all of the basemap/tuned maps for dsm/t3/t4/16g bins.. after looking at dyno graphs.. bin after bin.. me and IAM hybridized (my new word) the maps together.. so now we have
IAM's F22b dohc basemap mixed with Midniteracerx's turbov12 ignition bin
he came back tonite with results
Cliff notes:
to be on the safe side we added 5 percent fuel throughout the entire map,the ignition map is more aggressive then the LS and sooner to boot
so after about 2 hours of working with it IAM came up with this
: timing retard 10%
: added 5% below 4k then 1% fuel all over on top of that basemap (in addition)
what we came out with? an Average a/f of 10:7-11:7
10:7 in the low end(this is due to us being safe for right now)
we have uncovered two lean spikes that werent there before we are both thinking that its his peak tq and peak hp at these two points
peak tq being 4,700 and peak tq being 5,500
heres the full run
