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.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
