There was a thread recently about the UK P07, specifically the P07-G01 ecu, which is what basjoos has in the aerocivic. Supposedly this ecu does not cut leanburn off at 2600 and stays engaged in vtec. I pondered this a while and realized running the extra rpm my defeat the purpose of staying in leanburn in the first place, but nevertheless better than the US version. Good luck finding one.

Innovate XD16 gauge and LC1 wideband controller, I just put a new sensor in.
The vacuum gauge is an autometer Z series, but am uncertain of its accuracy.
If Honda used a pressure sensor on their insight engines you could probably fudge it a bit with the fuel controller and turn the map signal down some.
Thus far I'm running leanburn about 1" of vacuum on the gauge, the Apexi meter says 15 kpa so that might as well be throttleless, it only took 7% reduction to achieve this. There's definitely a lot more useable torque and in many places where only running in 4th and <63 mph was possible I can now run the same speed or greater in 5th.
In doing this the stoichiometric burn window in getting narrow, so now engine output seems to be more fuel ratio and rpm based rather than throttle position. Accelerating through 1st in leanburn goes pretty quick and staying up with traffic from a dead stop is possible most of the time. Also the engine is producing more HP and more efficiently at high load/rpm since the air/fuel is now about 13.3 rather than 12.3.
I'm searching for a suitable air solenoid right now, the resistor jumper on the TPS signal works too. Will post values and wire specs after I wrap this up, then we'll see if it was all worth it.
