HKS2530 stage 2

[bbenny]

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

[Dr_Drift]

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

May be interested in my post under the "for sale" section about the remaps from toshi.

207rwkw on 10-12 psi with a 2530, sorry but to me it doesn't seem right

[Cubes]

A 2530 generally makes around 220rwkw or so on around 1.1bar. When on the side of a RB20DET.

It does sound a touch low, but not by much.

Dyno's are a rough guide to power anyhow.

[bbenny]

remember that its cutting out at 5000rpm and the curve seems to be going up when it cuts.

wait till i get this cut out sorted, im sure it will make very good power.

well i damn hope so as ive spend a bit on it now!

[Cubes]

So that 10-12psi is that according to your boost guage or the dyno's boost guage?

[Steve]

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.

[bbenny]

Dr Drift, thanks ill give you a call soon

[bbenny]

lets hope so steve

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.

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...

[bbenny]

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.

[R32 Zilla]

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.

[bbenny]

let me know next time you come down, ill give you a run

anyway i would think all the fresh air in tamworth would make yours a shitload faster, in sydney turbos tend to be sucking in what others blow out the exaust

[DoughBoy]

Just going to add that the same turbo bbenny has was on my car, and only did ~194rwkw max. Then again I'm living in the inner west

[bbenny]

haha u are kidding right?

well i have posted the dyno print on the first page of this thread if no one has faith.

even better ill give someone a squirt around the block, you wont be dissapointed

[bbenny]

Well for all the cynics out there my car is having its ECU tuned on a completely different dyno. so ill post those results. but im pretty confident it will make good power.

[Roy]

the same turbo bbenny has was on my car, and only did ~194rwkw max.

Hmmm, go on tell them at what boost though... wasnt it like 10psi @6,500rpm or somthing silly???

bbenny, out of interest, can i ask who is re-writing your ECU?

[bbenny]

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.
