Should I Get My R33 Tuned?

[Nevastator]

Hi all,

Once again i've come to you in need of some help. My car ('93 R33 gtst) has recently started playing up, in the last month or so what's been happening is under load, full boost and high rpm, the engine light has been flashing. I've done alot of reading up on this and found that it is serious and requires attention. So this is me attending to it

The mods on my car are as follows,

Power FC

Splitfire Blue jackets

Boost T Currently running 12psi

Highflowed turbo (OP6-hypergear ~480hp?)

Greddy Front mount

Bosch 040

Custom 3" straight pipe all the way through

Standard injectors

Standard afm

What happens is when the car is warm (water temp ~82-84c) and I open throttle in either 1st or 3rd, from about 5000rpm the engine light will give me about 4 or 5 consecutive flashes. On the pfc display I get a peak knock reading of anywhere between 85 and 130. I don't have a wideband so i dont know what my afr is but I'm quite certain its leaning out badly. The guy i bought the car from said that it was tuned to 15psi (which i now think is bullshite) so running it at 12 psi shouldn't be causing it to knock so much.

I'm in the process of getting a z32 and nismo 740's

What i need to know is should I go ahead and keep driving it? Should I get it retuned? Should I wait until i have the afm and injectors then get it tuned? Just some advice would be nice as a mate of mine just blew his engine which had similar issues previously.

Sorry for the long post... Any help is much appreciated

Cheers

keep driving it with those knock levels and you'll find yourself walking home.. i was told anything over 60 is getting dangerous... so dont drive it that hard til you have tune, your probably running out of fuel with the hypergear turbo.

Always run on BP98. Will just a check from a mechanic do or should I go to a tuner?

Just for when I do have it tuned, anyone know a good Perth tuner that knows what they're doing?

[Tai1or Made]

Get it tuned.

[bozodos]

tried some octane booster?

[Manuel Kasko]

Get it tuned.

Try lowering the ign trim 3 degree's atleast everytime u go for a drive until u can get it tuned.

You do this on the handcontroller

Thanks for the replies guys, even the not so helpful ones... I'm getting it tuned in a couple weeks

Do NOT drive it on boost at all, not even 3k on boost, you will destroy the motor if it is pinging.

Do what JEZ said, remove 3 degrees from >3k and it should be safe until you get it tuned.
