Dyno Tuning?

[Sparks]

Hi everyone,

After recently purchasing my '96 R33 with a 3" Turbo back exhaust, boxed POD, solenoid boost mod (7psi) stock SMIC and Turbo I'm concerned that I should get the car Dyno tuned. With these mods would it be wise to get the AFR's checked and a general tune done? or would it be a waste with only minor mods. Could anyone recommened a reputable workshop to go to on the Gold Coast ?

...Last thing I need is for something to go Bang!

Cheers.

if it is running the stock ecu you cant tune it appart from a twist of the cas to put more timing into it. it will also be running very rich.

Is it running the standard ECU or an aftermarket one?

As above, there's no real way to tune the stock ECU - plus it should be fine with those pretty common mods.

If it's aftermarket, alot have hand controllers which you can check knock readings and other info

a dyno is never a bad idea if you have the cash as it can give the mechanic and indicator if things are on there way out, eg fuel pump, blocked exhaust etc..

with the stock ecu it can't really be tuned, but stick it on the dyno anyway to make sure everything is fine (AFR's)

All it will be doing is running rich.

And if you want to 'tune' the stock ecu you'd need a piggback like an SAFC or the likes. Work fine for stock turbo + bolt ons.

Thanks Fellas,

It is running the stock ECU no other management in place, and it runs without any issues. So a dyno would only be good to show numbers and look at the AFR's but there would be nothing that could be done as far as "tuning" or fixing the AFR's.

Puts my mind at ease about that issue then.

Cheers.

get a aftermarket stoichemeter (i cant spell it can you) mounted to an exhaust o2 sensor that will give good indication on how its going during driving im going to put one in my car, hooked up through the e11v2 though. your car would/should be fine but have terible fuel economy tho

[mad082]

not really much point spending a few hundred dollars buying a wideband o2 sensor for a stock car, as for about the same money he could buy something that actually alters the AFR's and gives a power gain.

go call Toshi, spend that O2 Wideband money on a remap that's actually worth something!

thats the shot i was just thinking for piece of mind for him. but if more mods are on the way than dont bother go get a ecu best thing i ever did aside from a turbo.

[Wacky Dee]

get a remap or a Nistune chip.. full blown ecu that costs $2k without major engine upgrades is a total waste. Nistune can handle timing/afrs, bigger injectors etc

Its an r33, nistune is out.
