Re: VOLVO 5.7 GSI does not achive WOT**Running Great!!!**
hello<br /> wow this thread is getting confusing. so far yamaha outboards are about the only engines with O2 sensors. the lap top diagnostics will only tell you what is not broken. experience with the gear will tell you what is out of range.<br /> post back with the fuel rail pressure at the bad RPM range as well as the injector pulse width of the computer. most systems monitor the knock sensor and if you unplug it it will go into default mode. setting the timing with the lap top is fine but it must be verified with an old fashioned timing light.<br />get the O2 thing out. learn the proper ID and function of your sensors. its all in the WT manual set.<br /> good luck and keep posting and remember fuel injection is simple not magic.
