My R33 ECU ---> CHIPPED

[R31Nismoid]

Hi everybody.

I've just recently purchased my R31 GTS-R

that has an RB25DET conversion.

Last night with Dr_drift and Meggala we establised it has a series 2 RB25.

ALSO... now this is the bonus part.

The ECU was just sitting on the floor behind the carpet and a few screws were missing.

So we HAD to have a look and one opened up we saw that the ECU had a nice daughter board with a chip... :eek:

A fully programmable chip that is.

Right down the the valve timing.

How cool is that. :Party:

No $1,500+ APEXI Power FC for me to tune the ECU and go fast :burnout:

[Guest MRE]

What type is it ?

[Guest MRE]

The piggy back chip that is.

[Guest INASNT]

so am i hearing correctly the comp is a r32 chip in the r33 loom with the extar valve timing bit??

[R31Nismoid]

No... this isn't the R32 chipped...

i was gonna let dr_drift play with that on mine for some ground work but there's more better things now.

It's a 33 ECU with a daughter board and on that board are several chips.

This car was a race/drfit car in Japan and has many mods.

As for markings on the chip or nothing... there are none. It's a generic sort of chip with the maps bunrt on it.

It looks like someone has done it in their bedroom sorta of thing... not something brought off a shelf that's for sure.

Maybe that's why it goes so hard

[Guest INASNT]

what other goodies does it have, turbo, cooler internals???

[R31Nismoid]

series 2 RB25DET

Massive STOCK frount mount

I think it has a T04E.. them came with them stock so i'm assuming it's what on there. Hits boost about 4,000rpm.

turbo extractors... STOCK

stainless steel exhaust manifold... again Stock!

It's got coils overs all round. Cusco is what's on there (i've got spare 500 pound springs as opposed to the 250/200 that are in there now)

5 Stud converstion -- > R32 GTR brakes

shortend shifter

R32 Forged GTR Rims

Monster heavy clutch.

260 km/h IMPUL dash

of course the ECU is modded

[Guest INASNT]

stainless steel exhaust manifold and turbo extracts r the same thing. And it cant be a massive stock fmic as the stock rb25det cooler is anything but massive or front mount!

There are extractors coming off the block going into the turbo.

And then off the ass end of the turbo.. the exhaust manifold is stainless steel.

so that is different is it not ?

or wan't i clear ??

And the stock front mount for a GTS-R is huge. TRUST ME. i know lot's about the R31 imports.

If you see the car i can explain it.

The GTS-R's were brought out (only 800) for the group A racing.

That's why it has lot's of good stock parts.

off the block to the turbo is called the exhaust manifold and from the back of the turbo is called the dump pipe!

[R31Nismoid]

oh... so it's got extractors and a stainless dump pipe. :bonk:

Easy!

still doesn't change the fact the ECU is chipped... with a chip that can be read and adjusted

[Guest INASNT]

yep, u coming to the dyno day dr drift is organising?? it will be good to see what numbers it will pull??

[R31Nismoid]

Yep!

I'll be there for sure.

it has no extra boost so i guess it's running around the 9psi mark with the big cooler and exhaust...

i'm being a bit conservative but i think i should get at least 180.

Dr_drift is more towards the 200+ though.

we shall see on the day though

Might even do some tuning now the ECU has been found to be chipped

[dAVE]

I would think you could go a fair bit over 180. On that dyno last week, my car pulled 173 with just remapped ecu and cat back zorst.

So u recon it reads alot higher than others?

[Jay95R33]

R31Nizmoid - Cool, if Dr-Drift can work out how to re-map the R33 ones it'd be great. But I think the write once 84 pin chips are about $70, and the re-writables are about $250 or so !!!

Unless your ECU daughterboard got rid of the 84 pin chip all together and uses a cheaper chip - now that would be cool..

well i dont think so. Phil's s2 r33 got 154kw. I think he has only exhaust done.

bring your car down and test it out

i am coming down!

just wonder how u can get such a high reading with stock cooler and boost!!

[dAVE]

forgot to say boost is 10psi.. There are no bleeders and it was only 1 psi above phils, so maybe my ecu is doing that. who knows.

could be other mods that i dont know about i guess.

[Guest INASNT]

japs, who knows what they do to our cars before we buy it off em!
