I cleaned the wideband sensor and tryed again. Gauge stopped acting up and I got some useful data.

This is exactly what was happening as lean burn was activated. I took the hand brake lever from the metro and hooked it up as a throttle. I set it to ~65 mph and once lean burn engaged I would start loosing speed so I had to pull the lever another click or two to maintain 65. I was getting about 40-42 mpg (~17.5 k/L) at 65 mph (~105 kph). I also tested fastest and slowest I could go in lean burn. Fastest was 85 mph. The slow side of lean burn wasn't a hard cut off. From ~65 mph and up I was at 18.5 or leaner. As I slowed down however the richer it was. Once I got to about 50 I was back to 14.7:1.
At 45 mph I was getting 50 mpg at stoich. I've got 223 miles and at half a tank so far. Mpguino indicating 37 mpg on the tank. I'll have to finish making the mount for the hand throttle and do some testing (front wheel skirts & front airdam hopefully) to finish off this tank.

What is the slowest lean burn honda's can maintain lean burn?



Also a note to any escort/tracer owners looking into lean burn; I am running Potenza re92's which are 165/65 r14. Stock size is bigger (175/65 r14) so mph readings I've posted are accurate with the smaller tires.
