well there is a good chance i will be getting an ebc i would like to have it on a low boost setting for everyday driving and wind it up when i feel like getting excited.

Does anyone have any recomendations for an ecu tune in sydney? apart from SAS as they are booked out for some time

bbenny - I would be more than happy to fly up and help tune your ECU for you. Without goin to aftermarket ecu you really do need the Z32 AFM. The problem is that after the RB20 AFM reaches 5 volts the ecu has no idea how much the motor is flowing. the Z32 item should be good for 300 rwkw or more. It's a good idea to keep the safc for future fuel tuning if someone who can re-write the factory ECU's is not available.

Fuel cut defenders only place an AFM output voltage clamp on, and hence is exactly the same sceario of youe ecu has no idea how much air you're actually getting, and tuning the SAFC will not help as the output voltage will still be clamped.

Feel free to drop me a line or call me if you need any further info or advice... 0411 878 961

Doc.

thats only .8 bar. So its pretty damn good. The turbo hasnt hit its efficiency range yet which is about 1.5 bar.

The big thing with HKS turbos is they come on boost hard, I get boost coming on at just over 2K with a 3037, hits really hard at about 2500 - 2700 (hard to tell exactly:)) but goes from about 4 pounds boost to 14.5 in only 3-400 rpm - its nuts.

With 1.2bar on that turbo (you got 8.5:1 CR so pretty boost friendly) you will be looking at 230rwkw easy.

207 rwkw on 12 psi !!! using a 2530 ....

I dont think so .......

Either the dyno you are using reads way high or there is something wrong with your boost guage.

Iam running a hks 2535 with all the support systems needed, running 19 psi and i make 206 rwkw which is about 10 rwkw down on where i think it should be. Iam in the process now of finding that extra power.

Tim.

I think I know where your power is lost...

You live in Tamworth!

Dyno studies prove that the northern beaches area is worth at least 10% more power. North Sydney ranks highest at 40% more.

It's all in the demographics man, all in the demographics...

haha yeah Doughboy is right, move over here and you will gain massive power.

I actually had the dyno guys hook up the dyno to the vacume to measure boost also, i called them today and got the boost measurement, the dyno recorded 12psi but it crept to 14psi from 5000rpm to cut.

Japsix, im sorry to hear yours is only making 206rwkw on 19psi, that sounds wrong.

My car has always done pretty well on whatever dyno its been on. with std turbo on 14psi it was making 170rwkw and running stupidly rich.

from what ive heard and read about guys with 2530 equiped RB20s they all seem to make around 220rwkw on 1.2bar (17.6psi) so mine doesnt seem too far off those i guess.

:cool::):(

Yeah i no what you mean, i think we all try to compare dyno figures from different dynos to much. The only way to compare is put all cars on the same dyno on the same day.

I may live in Tamworth but all my tunning and dyno runs are done in sydney.

Tim.

im not sure yet, Dr Drift has offered to rewrite it, i havent heard of anyone having theirs done by him, so anyone with experience please let me know, he seems like a nice guy. im going to call him this week to talk.

otherwise i may take it to some place in Artarmon that retune ECU's but once again ive had no experience with them, so if anyone has recomendations that would be great.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
