ign map didnt display.

Some of the features of your map are similar to mine. I'm surprised how little fuel youre running on decel, esp 2500rpm and below.. does it pop, burble and f@rt? I guess its hard to tell without seeing the ign map. If i take too much fuel out @ 100kpa i fear I'd blow the exhaust to pieces.

Who can spot the hwy cruise points? :D How does she go on fuel? I found after installing the MoTeC fuel consumption dropped from 30L/100 to around 11L/100 in similar driving conditions (city stop/start and trafficlight dragstrip)

Ign map looks pretty tame at WOT. Had to look at it a few times, the Manifold Pressure axis runs the opposite direction to your fuel map. LOL

I'll see if i can find my other laptop and i'll post up my maps. They're still a little rough as they've only been hacked up driving up and down the Cumberland Hwy with MRE-40L, and then a few hours on the Dyno at Crescent :)

we've got some pretty wild torque (measured by seat-of-pant-ometer) around 40* BTDC at WOT :) No pinging either! After Joe @ Crescent finished with her on the rollers we found 36* with a bit less fuel was a better combo.
