Asking for a little help here. On ecmspy, o2 voltage jumps around . Ego is 123.4 of which has never been that high. Got bike up and running after motor roll and things are different . Before I generally had 102 or so. Going to check for wire trouble first with wiggle test. Voltage test. Pin 4 and pin 7 showed .4 volts or so . Rode casually today to reset afv and pulled off freeway had a 2200 rpm idle. Motor cooled and idle lowered. Acted upon startup like no cold enrichment going on. Once warm bike ran good 2000 up but idle sucked. Siphoned a lot of old fuell out so need to replenish tomorrow. Ecm speaks of taking afv and multiplying fuell maps by value , then set afv too 100 and reriding . I don't see how to do that . Tps has been set hot so that is done . Issues with getting around in new spy is trying me . Thanks for all help.
