What The*&%$&* Is Going On With My Car!

Doesnt excuse the fact basic things like a fuel pressure test among other things hasnt been performed.

Its not even a 5 min job.

OK, heres the outcome!

-Fuel fluctuating problems was the Fuel map sensor in the microtech! Rob from Creatd replaced it, so now

the fuel line doesnt keep changing & is a much smoother line compared to how it was going in zig zags!

-Lagginess was a couple of split rubber hoses, one was major

I am now very happy, the car was finally tuned on 14psi and made a strong (good curve) 212kws at the wheels..

HOWEVER this is a brand new fully Digital Dyno which has had cars put on there from other shops claiming 230rwkws etc

and have made 20-40 less kws...

Basically second gear, no matter what road surface once u nail it as soon as it hits around 3800-3900rpm it completely

brakes traction, sometimes even just goes crazy off limiters through the whole gear.

Andd the Bee *R Limiter is JUST SE* !!!!!!!!!!!!!! ABSOLUTELY LOVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

So thats about all guys, thanks heaps for ur help!!

Oh and i stil strongly urge everyone not to get this turbo for an RB25! exhaust housing is just too small, should work

very well on an SR20 though!!

If your going to the length of printing this out for your tuner, seriously... go find someone with an idea.

They clearly dont and you wont ever get the best result if they cant do some basic troubleshooting

If anyone has an idea its Rob from CREATD!!

Dean was simply askin for a few opinions, CREATD probably hadn't got back to him after they completely looked into it for him.

CREATD tuned my Aussie Skyline R31 in back in 2003 (i think), was an NA motor, only bolt-on mods(turbo, cooler, etc), had approx 230,000k's on the clock from memory at the time, made 165rwkw on 10psi (safely)

i only just sold the car a few weeks ago. Since the tune the car did not miss a beat!!!

new owner put it on the dyno, still made 164rwkw on 10psi 4 years after the tune and the engine now has approx 300,000k's on the clock!!!

Nice story fulock.

Anyway, good to see it was sorted out Dean.

Although dont believe the "dyno reading" high/low hype. Because everyones dyno reads "lower" than someone elses

As long as it drives well, and you use the same dyno or each mods/retune.

Then you'll see the differences.

Yeah well R31Nismoid i think people with cars up in ur area are a little more swtiched on..

Here in the northern suburbs what seems to somehow rule unfortunatly is cars with Cut down truck intercoolers

and 20x6.5 inch wheels with 215 rubber...

I think thats what causes shifty dyno owners stuffn around with the modes on there dyno's to impress customers more..

A mate of mines manual VN 6 stock as a peeled orange? made 125kws at the wheels on one of these dyno's im talking

about...

By the way these cars had that same figure at the ENGINE about 17 years ago...

I grew up in the west

The dyno is just a gauge to work from.

If you use the same one all the time then your laughing
