as i progress more on tuning issues, i notice one thing; we are trying to partial/WOT tune on roads, parking areas, other appropriate places. it is clear that these drives are exposed to elevation changes, because it is very hard to find a long long track with zero ramp. and next is the engine load problem (trying to fix throttle).

have you tried load bearing dyno? it does not present problems like ramp/traffic/traffic lights/limited distance and so on.

may be WOT tuning can be handled on a long empty road, but partial throttle seems to demand more.

i read ur messages about ignition tuning also. say u would like to enhance some zones of ignition, install a water injection system so that you can have more advance for WOT zone, etc. isn't that pulling on the load bearing dyno is the professional way to go?

what do you think?
