hey guys my car is pinging since im still running the non turbo fuel pump with a rb25det motor.

i have a bosch 040 fuel pump and a sard fpr and nismo injectors in my room.

im not going to get my car tuned anytime soon so what should i do?

i have a power fc and i goto "ect" and goto the bottom section and click yes, assumed it was factory reset but i let it idle for 30min as it said,

and it doesnt seem to change and the car was still idling rich so i just put the stock 1 back in.

so basically should i just add the 040 pump and do i have to add that fpr aswell?.. or i dont need to change anything else except the pump?

or should i add the nismo injectorss, fpr, 040, and try to reset the pfc and turn the injectors down?

i just want to know what i should do,

#1: 040 -

#2: 040 fpr -

#3: 040 fpr injectors pfc -

thanks

I would stop and have a good think about what you are doing instead of creating about 15 new topics when most of the answers have been asked and answered so many times before.

Changing the pump will make sure you have adequate fuel supply. There is no need to change the FPR or injectors.

Given your reluctance to tune your PFC I am not sure how you will ever sort out all these issues. Doing things half arsed seems to be part of your problem.

If it was my car I would've just bought a fuel pump and installed it. No need for FPR, injectors or PFC.

Regardless of anything, you should install the pump and upgrade your fuel pump wiring.

If the FPR has a gauge built in it will be a handy diagnosis tool, might aswell install it, search the forum for adjusting aftermarket FPR (set it to stock pressures).

If there is no gauge on it then there is no real point to installing it as the standard FPR is fine. Either keep it as a spare or sell it.

The larger injectors are not really needed unless you are going to get it tuned and plan to reach figures higher than the stock injectors will allow.

Again, same with the powerFC. Unless you have decent mods (or plan on them) it's not really needed.

If you really want to put them in the car, find out how to reset the powerFC to standard maps, install it and the injectors, adjust K factor to suit the size of the injectors.

So this is an N/A ehgine with a turbo put on it, are you still using the turbo or na injectors, if your using na then i would certainly upgrade to atleast turbo injectors, what ecu are you using na or turbo, either one will not run all that well as the engine is under a completely different set of circumstances that it was designed for, i would park the car untill you had money for a tune, use the bigger injectors, pfc and get a z32 as well, the fpr is an option but really an fpr is mainly used to get a little bit more flow from injectors when they start to run out of steam, this shouldnt happen if you have chosen the right size injectors.

Lol I know... 1st I had all my parts and I was told I need a fpr,

then I was told I reallyshould get injectors before my tune so i looked and found some sard injectors,

then everyone said I should get nismo so I saved for them,

them my highflow turbo seals went so now I still can't tune it :down: how annoying this all is...

So now I just want to add what I can and I need the pump 100% so I was asking how I should do it.

yes I've had many post's but I've also ran into alot of dead ends so Now I'm just doing this and saving/fixing everything lol!

Hope that made sense cause I'm on the iPhone typing quickly,

It's a fully converted n/a to turbo... Engine, loom, ecu, dif!

Just not brakes, and fuel pump. I want to do the fuel pump tonight that's why I made this thread so I can see what way people think I should do it.

i see, well i would just do fuel pump then, from what i have heard the factory fuel pump would flow more than the injectors anyway.

Ok so I'll just add the pump with no fpr, it shouldn't overfuel with standard injectors?

I have seen post about wiring or something briefly, do u need to rewire it or anything else?

If so could u post a link, cheers

      It is an absolute lottery. They can and have died at stock boost with low usage at all. The turbos are now anywhere up to 36 years old!

      Huh, wonder why it blew then. I never really beat on the car THAT hard lol I dailyed it and the turbo blew after 6 months

      That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By GTSBoy · Posted

      Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.

      I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
