R33 GTS-T ECU differences

Recommended Posts

I have a series 2 RB25DET from a GTS-T. My engine ECU was damaged the other day so I'm looking for a replacement.

Can anyone tell me if all GTS-T ECU's are the same ? Can I uses a series 1 ECU on a series 2 engine at all ?

From what i have seen of some dyno results the Series 2 for the 95 model gtst's are superior to the series 1 ecus because the 95 series ecus have a better air/fuel ratio pretty much a better factory tune. I'm not sure about the 96 series 2 ecus etc but in general year after year of production of these cars they usally fix little bugs and clean up fuel maps abit etc. Try and find one that is specific to your model, if you cant find a series 2 one try and go for whatever you can get if you need quick. My 2 Cents

i thought series II only start from 96 models up?

because i think i have a late 95 model, and i;ve only seen 96 models and above which start having extra air bag, different interior, kit and etc.

or is there actually a 95 series II ?

The '95 model is often referred to as the series 1.5 because it looks like a series 1, but has many series 2 components, such as ECU, engine, AFM, etc. If yours is a late 95 model, it's definitely a series 1.5 and has the improved bits in it.

i think that answers your question perfectly. its a 1.5 so No there is no or highly unlikely that there is a 95 series 2.

I have an october 95 series 2... has the different squarer headlights, bonnet, grill, bumper, passenger + drivers airbag, update interior, colour coded skyline badge on the boot instead of the clear one that matches the indicators and so on. Mine has the mesh grill instead of the letter box grill, apparently an indicator of early series 2.

From memory when looking into my ECU ('95 Series 1.5) their are 7 different R33 GTS-t ECU models. The ECU I had was in the middle of that list (4th or 5th). I'd love to know what the difference is of each individual model.

Here is a pic of my Stock ECU: http://skylines.pnc.com.au/ecu.jpg

If it helps any - Mine is a Sept 95 car (series 2 motor, in a series one car) and I am running a 1993 ECU in the car cause I blew up the stock 1995 ECU.. :)

Soooo I'm pretty sure a series 1 ECU will run a series 2 motor.

If your looking for ECU get your self a Power FC direct replacement ECU. Less hassles of wiring, uses original sensors and is tuneable up to 600hp, what I like about this ECU is the detonation warning light which is really handy for monitoring purposes. It's about $1600 brand new incl. GST with warranty and tech support if needed. I beleive the price is only for the ECU excludes hand controller.

The dates the jap use (for years) are based on eras. The last one, under emperor Hirohito was Showa, the current one is Heisei under emperor Akihito. The era began in 1989, so that year is Heisei 1, 1995 is therefore year 7

You can find the build date on your jap compliance plate, if you have the original books, you will be able to find the delivery date too.

You can get the PowerFC + HC from Greenline.jp for $1,304 + Shipping + any taxes (if it gets pulled up for customs + gst).

    • The springs just lets the valve bleed off pressure/oil and it bypasses the feed gallery and heads back to where the pickup feed is On the LS the oil gets the the bearings...eventually  This vid explains the OEM pump well IRT the pressure release valve and how the bypass works The oil pressure light coming on intamitantly could just be a sticky valve, but, why pull something apart and not put something better in  I believe the low oil pressure light comes on somewhere between 5-10 psi Well will stick a gauge in after the installation to see what difference it makes at hot idle and higher RPM, and by high RPM I mean 6300 RPM.....LOL
    • My bottom end was rebuilt... so I think it's standard? Or refreshed.. standard? I didn't do it - I bought it with a lot of receipts but it has new bearings, new pump and was re-assembled. Apparently I have the standard flow, standard pressure pump. I did notice the oil pressure for a LS at idle is quite low, but not critically bad, I am happy that it's at about 28psi now (that my gauges work/don't leak). I would have probably specced the high pressure one, but I'll admit my ignorance after making my other post, I don't see how the pressure spring changes things. Given the pressure is a resistance to flow... high flow should also = high pressure, and your oil pump specifications should be dictated by how the engine is built (hence the sincere thankyou video man)
    • my first time on the track, just after getting the 32. tyres were 3yr old NT01's, rotors were cactus, pads were street pads. You can see the vibrations when I hit the brakes lol. After this is when I put new BDA rotors, Hi Temp Brake fluid and Intima type 2 pads. Wow what a difference
    • I second the recommendation to use a power bleeder. Pressure on the cap, if you want you can try some vacuum on the bleeder too with a hand pump. Pressure is needed on the cap to make sure that everything only goes one direction instead of potentially getting air sucked into the bleeder. 
    • Which one do you use? Your bottom end is still standard isn't it?
