[VIC] SAU dyno day, saturday March 1st @ RE CUSTOMS Springvale

the datascan said that the code 34 came up 44 starts ago... so i'm guessing it came up during the compression test as we may have disturbed the wiring when moving the balance tube. I reset the code and restarted the car and it didn't come back, i thought if the sensor, or wiring to the sensor was screwed then it would come back straightaway? Checked resistance with my multimeter, I do have continuity between plug->ECU and plug->sensor, resistance values are abit out though...
Don't think it's a fuel leak in the engine bay, i can't smell any fuel in the engine bay... the only fuel i can smell is the stuff being thrown out my exhaust.

Yeah it shows 36psi at idle, when i remove the vacuum it jumps upto 40psi. Turn off the car and it holds 40psi. 2hrs later and it's down to 20psi. How long is it supposed to hold fuel pressure for? Would leaking injectors cause the pressure to drop like that?

I'll check if the code comes up again today and if it does we'll bypass it, my car has never pinged (mainly because it's always running rich) so bypassing it shouldn't be an issue. But probably won't run until I get the O2's changed.

yeah i was abit unsure when i bought them as to how long they'd last, maybe i just got a dud one. it was perfect when i installed them, ecutalk showed the voltage changing really fast as it should. now it only sweeps once and then sits there at 0.3 volts... doesn't move until i get off the throttle and then rev again. should be cycling once a second at 2000 rpm, it doesn't do that anymore. I will check it manually with a multimeter though.

 

man i hope everytihng works out man...if u nedd anything give me a call and ill help you out...also if u need some nissan parts (fuel rail, etc.) or watever let me know...cheers

Sorry guys, but back to the topic, my friend and I were thinking of going to the dyno day, can anyone confirm RE Customs' dyno underreads?

 

i think 0.3v means the heating part of sensor is dead (unless not wired up correctly) as o2 sensors normally starts at 0.3v when cold.

 

well i think chad's was something like 30rwkw down on what his last dyno run was and he has more mods now. and we looked through his car on saturday and there wasn't anything that would cause a drop like that. so maybe it does under-read or it could just be that the other dyno was over-reading. I've got a few friend's who've had remap's at RE, none of them said that their dyno result was low. And none of the people on SAU were saying anything about it under-reading.

 

thanks for the info. it's still showing 0.3V at 2000rpm.... the other one is fine though. Also my det sensor code hasn't come back, still getting code 55 which is good.

Not sure if i'll run, will decide when I go down on saturday.

 

something is not correct with my car atm so you shouldnt be comparing the dyno for my run....still tackling the problem weather its fuel delivery or a/f ratio etc dont know yet as i havnt had time to tackle it, but i will soon...

 

whos got the most hp. in melb

 

well thats an easy guess alex

 

Real or Imagined ?

:biggrin:

 

i don't really know ..( Simon)
