Ok guys this all started a week ago when I was having some problems with my o2 sensor. I changed the O2 but now for some reason when I accelerate up to 5000 rpm I loose all boost then my afr goes nuts.
If this is a timing issue what would cause a sudden loss of timing?
I tried my buddy's mines ecu and the same thing happens but at 4500 rpm. It actually happend with his ecu first now it happens with my stock ecu.
Im using a safc 2 on a stock ecu. 550cc inj , z32 MAF, megan fuel pressure regulator, walbro fuel pump.
Sr20det loss of power
Re: (574-240sx)
why am I using a fpr period or why MEGAN?? lol i heard they are crap though ...(after i bought it).
no boost leaks. this only happens at 5000rpm

Re: (574-240sx)
the o2 is for an rb but that wouldn't cause a loss of boost!!.574-240sx wrote:Was the o2 sensor a OEM nissan one for the SR20det? Why are you using an aftermarket fpr and a Megan one at that?
Re: (bajansr)
Ummmm, the RB series motors have a distinct O2 sensor to themselves. So, using one in your SR20DET will cause some problems......
