I Cant Wait For Christmas!

[Toshi]

you are working it out at the flywheel not the rear wheels, it is also working out using gasoline stoich of 14.7:1, which you will know isnt going to work at WOT on a turbo car without detonating its ring hole out

Also, Naturally aspirated and turbo engines are completely different

So Stop miss leading people

OK

I picked up from this forum for you.

Could you believe me or do you want to more?

You can pick many cars from forum.

Also I tuned hiflow turbo and stock injector car over 30 cars.

[Randon_I_Am]

ermmmm, every one of those examples had an adjustable fuel pressure regulator...

I thought this was all about standard injectors with standard rail pressure?

you could probably make 1000hp out of 370cc injectors if you run 300psi rail pressure...

Also Kasko, go the NIStune, easy to use software and does everything thing you need. and if ya need to change something you can just get a retune done locally and your set.

I've got mine running from my sterio (carpc), so i can fill up with e85 and change the tune while sitting at the servo.

This...Also got a PM from him saying the same crap

all were either hub dynos (read higher than DD rollers) and/or had an adjustable reg

most of them didnt even have turbos capable of making 250+

Also said that to do it, you MUST still have the standard rubber turbo inlet....errr...righto

[Manuel Kasko]

What exactly are we talking I need for Nistune though.

I been trying to read up about it and it sounds like a bit of a screw around.

Tell me if im missing anything.

Also do I lose any functions such as my aircon etc.

-Z32 ECU or R32 ECU (what motor from the R32?)

-Z32 AFM

-Some window switch (read about it but wouldnt have a clue why I need it lol)

-Nistune board (do I need software or is that only if i want to have it on my own laptop?)

Thanks guys

[Manuel Kasko]

Also even if he is wrong with that shit.

His saying $700 for an ECU + road tune with him. (1 hour)

Seems pretty reasonable?

[zebra]

Ahk, you can either use a Z32 ECU and find someone to install who has done them before (need to swap a few pins around on the ECU plug)

or and R32 RB20 (gtst) Ecu, easiest option as it plugs straight in, but Rb20s do not have the variable cam timing, which is where the MSD window switch comes in (you use it to switch vct on and off, on at ~1100rpm and off at 4700rpm)

You dont need the software unless, as you say you want the software on a laptop, It is handy if you want to run E85 and PULP as you need to change the maps

No functions lost, will retain A/C, power steer idle up etc etc

so it is all as per factory (it is a factory ecu after all )

[Manuel Kasko]

Zeb,

Does this switch do it automatically

Because f**k flicking a switch each time I change gears haha

[zebra]

nah, it picks up the rpm signal and ground the VCT solenoid to activate it.

Does it all by itself

[Manuel Kasko]

Haha I was worried I was going to forget to switch it and end up looking like this.

So now.

My plan is to price those things.

Then work out between Nistune and a toshi

I would love to get a Nistune but trying to find everything

and get good prices seems to be a stress.

Thanks guys for the input.

[Toshi]

I told $700 road tune and dyno tune include 1 hour dyno tune.

For std turbo Road tune only $550 dyno tune only $600 include R33 ecu modified and chip.

Road tune and dyno tune start 10AM finish around 4-5 PM

I real time tuned Mr David Stankowski RB25det engine drift car in gold cost last time QLD trip and he got second place after my tune! PRO TOUR 2011-----Round 4----QLD RACEWAY----Sun july 31

He is using my remapped ecu.

Not nistune board.

[zebra]

lol because his driving ability and chassis setup had nothing to do with him coming 2nd

[Toshi]

Yes,he is very good driver.

His engine is almost stock and turbo is stock turbo.

[zebra]

I'm over this...

If you want to keep telling people they will make a GENUINE 250rwkws on standard injectors with a standard pressure reg, then go for it

One last thing though, how many of those 250rwkw (with a standard pressure reg) cars have backed it up on the strip by running 110+mph

I bet none of them have

Edit - it would be more like 115-120mph

as I was running 107 with 200rwkws

[Toshi]

How is this

My customer 300zx ,std 370cc same size RB25det injector ,std fuel pump, std AFM, std turbo , std fuel regulator,stock dumps and front pipes.

250rwkw at 15 psi 11.5 fuel ratio on mainline dyno.

[zebra]

you are really fishing for results now aren't you

LOL at the lean spot at peak torque...have to pull much timing there to stop it pinging its head off?

and peak power at 4000rpm? nah I dont think so.

try again

Im using knock monitor k-mon and knock around 20.

Anyway Im talking about injector.

This injector is 370 cc and std fuel regulator.

220kw is not injector max.

[zebra]

there are 370cc injectors on my 1JZ too

anyone who has turned the boost up on those will tell you they too run out of squirt at 220-230rwkws

[Toshi]

OK

What % is your injector duty?

Normally under 80% is best.

Around 230-240kw 80%.

250kw is around 85% but if car is not race car I think injector do not over heat.

If your tuner think injector duty 70-75% is safe for race car , yes,Im agree.

But its not injector max.

[zebra]

My car saw 100% at 235kws and started to lean out (had a big fuel pump too)

The injector needles do not close properly over ~90% duty and the spray pattern and fueling goes to shit as the solenoid in the injector cannot keep up

which ever dyno you are using is reading high if you think that 240rwks is possible at 80%, you are only getting around 300cc/min which on a 2.5L 6 cylinder engine is worth around 300BHP which is 225kws at the flywheel! factor in a 16-17% drive train loss you are looking at roughly 190rwkws

which coincidentally my Rb25 made 195rwkws at 13psi and 82-84% max duty cycle

[TiTAN]

Go the PFC or any other stand alone

R33 Ecus really do not like the Emanage (from experience) the standard ECU has too many protection features.

Here are some NEW options available to you

http://adaptronic.co...7&category_id=1

http://wolfems.cart....ils/696060.html

http://www.vi-pec.co...s/pluginecu.htm

But for ease of use (ala plug it in and drive the pfc is great)

but note, despite the Wolf, Vi-Pec and the Adaptronic being more expensive, you wont have to buy a Z32 AFM when you want more power as they are map based ECUs

They also all have inbuilt boost control, just need to buy a solenoid and wire it up. they can also control extra fuel pumps, thermo fans, Nitrous, support data logging, trac control multiple temp based rev limits pretty much anything you want.

The PFC will not run any extra things, so if you want any of the above you have to either get additional controllers etc

the Wolf and the Adpatronic can run flex fuel sensors if you want to go E85 or PULP or anything in between.

ESP are Vi-Pec dealers, and they go for around 1600-1700 + tune

Something to think about

the vipec will also run the flex fuel sensors.
