Reset My Ecu Today, Noticed Some Stuff

[scheris]

i.e. take of bat term hold brake peddle a few minutes

prior to my resetting the ecu, my stock boost gage would sit half way between +7 mark and the half way on the + side of 0.

now it sits just on 3/4 of the full gage, feels slightly, but only slightly slower (good ol seat of the pants dyno), and possibly better fuel but i have only just tanked her up so will have to find out how it afects my mileage.

waked in the second half of the bottle of injector cleaner to.

some funny things noticed when measuring the voltage on the o2 sensor, 2 wires dead, 2 white, 1 black, recently imported vehicle, im the first australian owner.... so wondering about that one.... and my side fed injecters are covered in purple plastic. what colour are stock 33 s2 injectors ? wondering if one of the previous owners put in some aftermarket squirters, would possibly explain the rich running unless ofcoarse if the standard nissan/nismo injectors are purple in colour. car seems to have been modded in the past slightly and returned to stock prior to import so its a possibility.

the bloody o2 sensor jumped from .2-.3 on idle to 12-13v on open throttle, probably misuse of a multimeter

The reset will force the ECU to relearn the knock from the type of fuel you're using. It shouldn't affect the stock boost controller though. It may be using less fuel though.

The o2 sensor has three wires as you say. One is signal (black) and the other two are heater wires... I think they just have power through them? It only gets used at idle anyway, so it shouldn't affect regular driving. It should read between 0v and 1v, so yeah, possibly incorrect setting on the multimeter?

My series2 injectors are purple, and look original, so i'd say yes.
