Y/T DataMaster vid with throttle movement... - ZR-1 Net Registry Forums

Schrade,
Not sure how well monitor mode captures data but i can tell you that when i recorded my data after replacing the injectors and O2's, my LT counts were rock steady at 128 left and 129 Right in OPEN loop. RPM's were 775 at idle. In closed loop they moved between 125/130 Left and Right until i reved her to aout 4k rpm. At that time the LT counts went to 128 L/R and stayed there until throttle release. I noticed that your LT counts were moving in open loop which i don't understand as the ECM sets a constant 14 to 1 AFR. Maybe nothing to worry about but i thought the LT's should be steady in open loop. Maybe someone with more knowledge can help here and yes a .xls file could be helpful.
