ecu apexi pfc

thanks for the info guys

Hi need a good tuner for the r33 ecu: PFC who do you guys recommend?

with a clean cat you should be able to see the thru it

if you think its a blocked cat just remove it and have a look it will only take you 10 minutes .only four bolts.thats what you want to find out right as the title says.

1. GEETR yes tuner did stop the injector duty at 60-70% because the boost would drop off in higher revs so he tuned it to that.he could not find the problem,i was happy with it anyway and left it at that.i found months later that the intake hose was sucking close causing boost drop excessivly.i fixed that but yet to be tuned. cant wait to get it back on the dyno . 2.mickr33 thanks for the info looks like i might just squeeze just a little bit more once i get it tuned.

yeah i spose your right pretty much near peak i think the turbo is rated to 260-270 rkw i will post up the dyno sheet soon.

please stay on topic,i just to want to know can i get more power with bigger injectors ??? Car: R33 gtst 1994 MODS: apexi pfc nismo fuel reg slide performance highflow turbo stage 3 hiflo exhaust 3inch-split dump bosch fuel pump internal z32 afm garret wastegate acuator new 15 psi tuned 230rwkw

as they say "YOU GET WHAT YOU PAY FOR "

it could be dirty or faulty AFM. give it a clean with electrical contact cleaner to start off.

good to hear bikey,that intake mod solved my problem,waiting to see what you come up with on the dyno

hi bikey i had the same issue with my boost dropping at high revs on my high flow ,tuners were stumped until i saw the rubber intake pipe sucking close at high revs, read this it has solved my problem http://www.skylinesaustralia.com/forums/Lo...87#entry3458787

no,its not the air filter,its a k&n filter never had this issuse until i raised the the psi,it all fix anyway,good point anyway.

ok people i did that mod with the pipe in the middle of the standard intake pipe,went for a drive and it works.no more power loss,me very happy.

im gonna try this out on the weekend, i have no time at the moment (for once search button has worked)http://www.skylinesaustralia.com/forums/t173019.html&hl=inlet+pipe

yes it is softer

your joking john isnt that silicon hose sposed to eliminate that problem (sucking close) if so its a complete waste of money,im gonna put my stock inlet pipe on and reinforce it,did the problem go away for you onced rienforced??

cubes i have that silicon inlet hose thats not sposed to suck close.i will put my standard inlet hose back on tomorrow and see what happens.

Car: R33 gtst 1994 MODS: apexpi pfc nismo fuel reg slide performance highflow turbo stage 3 hiflo exhaust 3inch-split dump bosch fuel pump internal z32 afm garret wastegate acuator new 15 psi tuned My problem is when i reach around 5-6000 rpm it looses power,and boost reading drops excessivley as if somthing has blocked the air intake. has anybody had this problem?i have checked all pipes and fittings?

so after all this what were the results on the dyno?

ive got a slide highflow,what do you need to know?

yeah you wont feel much difference,now your ready for some more mods.

mate if i were you i would disconnect the battery after youve depressurised the fuel system,just looking at that wiring you dont want any sparks near that tank.

need a R33 a/c compressor melbourne
