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.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
