As SOON as the compressor bumps on, mileage plummets to about 55 to 60.

I think that the OD in the CVT is analogus to lean burn in the manual car. It is very hard to get the transmission into highest ratio and running the A/C or going up a hill causes the CVT to step down. When I do get the transmission into max OD, the car can get amazing mileage.

I can get the max overdrive at about 35 even with the AC running, and mileage goes over 100 mpg, but the SLIGHTEST movement of the accelerator causes it to drop out. Almost impossible to hold unless it is very flat.
With the 2nd Gen Honda Civic Hybrid, if you release the accelerator slightly for the engine speed to drop down, there is a certain amount of pedal you can put back in to where it will add additional load to the engine without ramping up the engine speed. They seem to have it down to an art with trying to keep the RPMs as low as possible. Has anyone with a 2nd Gen Insight tried to do something similar. They do this as part of their acceleration, bring the car up to a certain speed, release the accelerator a tad to get RPMs to drop down and use just enough pedal to add load without raising the revs.
