Hi all

It's my first time posting in sau as i recently purchased an NA R34 with an aftermarket turbo.

First of all, can anyone recommend a good tuner (preferred specialised in skyline bnr34) in Melbourne? I would be getting the car retuned after fixing a problem that it currenly has.

Secondly, so the problem it has now is that it can rev upto redline on P mode but when driving the rev caps at around 3000-4000. Up to this point i think that either there might be something wrong with the AFM, or i have to install the aftermarket fuel regulator and fuel rail back into the car as i think it could also be the problem from the fuel pump. However i am no specialist in cars so if anyone of u guys can give me anyhelp that would be greatly appreciated.

The previous owner did told me about this rev-capped problem and gave me the aftermarket fuel regulator and rail, however i am not 100% sure if that is the solution to the problem so i am wondering if the problem can be easily fixed by a professional tuner/mechanic incase if it is something non-trivial.

Also, both the fuel injector and fuel pump are aftermarket and not stock, the AFM i believe is a Z32 AFM.

Cheers

Also that car sounds butchered.. stock RB25DE ECU with a turbo slapped on it.. don't dick about with the fuel reg or mixing and matching shit without an aftermarket ECU or at least a piggy back (as you have an auto)

Sounds like you bought a problem. Which is why the guy sold it.

Prepare to open your wallet.

hmm prehaps not as bad as u thought,I've had my mechanic looked into it and he thinks there's no big problem but it just take time to find this rev-capped problem,which is likely to be either afm or fuel related.

The car has GReddy emanage ultimate ECU since it's an auto as well as many other mods with over 10k receipts, so I am wondering would a professional tuner be able to diagnose the issue better for me?

Yes a tuner would be your best option

Sorry my bad for creating multiple threads.

Also, apparently Chequered Tuning doesn't tune emanages anymore. Is there any other suggestions? Thanks in advance.

I would suggest getting an Adaptronic e420D and splicing it into your loom to control injection/ignition and letting the OEM ECU control the automatic box.

That "rev cap" as you call it is actually a TP Load cut.. your ECU is going "wtf.. why is there so much air going into the motor, I'm cutting fuel"

Talk to Trent, tell him the bastardised setup you have and someone from SAU recommended using an Adaptronic e420D to make it boogie.

I tried, unfortunately the guys from Chequered Tuning said Trent wont be able to talk to me over this matter, as apparantly he doesnt get involve with emanage anymore ;/

      True, might get it looked at. Found out you can in fact flatten the 12v battery relatively easily too the other day (kids lefts the hazards on) so meaning to get that checked in the new year. What's odd is it'll blow cold from both vents if you have the ac down as low as poss (18), but anything else the passenger one blows warmish. Also has been summer since I got it obvs but noticed it didn't seem to want to blow hot last night when we had a cold snap.

      You ask for things. You specifically state you want responsiveness. A link was provided for a far superior, more responsive option. Find a MX5 workshop that will install it for you. Maybe MX5 Mania will throw on the Fab9 kit. It seems they want to charge almost 14K installed for their kit, so if they charge you $6K to install the FAB9 kit then you'll be ahead? Though really, the 2.5 with a 2860 running low boost will more or less feel as good as anything else. It's a lot of displacement and a small turbo. Think of a more modern RB26 with one stock turbo :p TBH, truth be told I've been driving my own car, and use about 50% throttle at most for 99.9% of the time. Mr Bogan is likely similar so this is all going to be semantics for the use case he actually has. (He'll be happy with anything relative to now) However, the EFR is hands down far superior in this use case. You really, really, really, really do notice it over the Garrett or equivalent.

      You are correct, the earlier the torque, the earlier things snap

      Gents, it will be getting the MX5 Mania kit and the 2.5 will be staying where it is My query was about the 0.64 or the 0.86, whilst the 0.64 might spool a bit faster, would the 0.86 be better IRT EGT and mechanical sympathy, with only a small difference in spool And as I assume I won't need alot of boost to get to 200kw, probably around 10 psi, and with max rpm at 6500, would high EGT even really be a issue with a 0.64 I'm heading into MX5 Mania at the end of Jan to discuss the install, so any info is welcome prior to that Basically have a chat and book a time so they can throw on the turbo kit, and fit a oil cooler with a thermostat, drive in drive out of course  In other news: just finished cleaning the car inside and out, it's now all ready to get covered in bugs and dirt driving to Goulburn tomorrow to lunch,  and go for a stroll along woolondilly River with the daughter and her boy, and of course, visit my grandcats and my new grandpuppy

      Sounds like it has an actual problem with mode select doors, or something.
