3bar fp reg 02 lean rich test experiment Posted by jak [Email] (#195) [Profile/Gallery] (more from jak) on Thu, 8 Mar 2001 18:43:03 Members do not see ads below this line. - Help Keep This Site Online - Signup |
today for kicks I put mt vantage tool on my 02 sensor ren a lean drop & rich snap test on it I am running a 3bar fp reg & a self tweaked apc & the watter cooled garett turbo 85 spg.
heres what I found first I tested the O2 it was able to snap from about
.1 V to .9 volt & back in 10 miliseconds each way, which is quite good.
next I unpluged the vac line to the fpr & pluged it the O2 voltage went up to about .9 volts & to my suprise the ecu was able to compensate for a full 3bar fp @ idle & started to swing from .1-.9 volts like it should @ normal fp.if it can do this at an idle @ 3bar all is well in the saab world.
long story short those of you concidering turning the pots in the apc & running the 3bar fp reg. the ecu is fully capable of makeing up for the extra fuel presure & wont afect your mileage or emissions untill driven hard.
hope this is helpful
