Plugged in my nistuned z32 ecu today which i got from Matt at nistune and the car seems to fine with it in, but the exhaust temp light on the dash is on as soon as the car is turned on.

I have a 96 gtst that I always thought was a series 2 which meant I didnt have to worry about the FICD pin on the z32 ecu being different to the s2 rb25det ecu.

Taken from the nistune website:

5) FICD output – pin 33

* Series 1 R33 only

The R33 Series 1 RB25 engine uses pin 33 for the Exhaust Overtemp Lamp on the dash.This line should be disconnected as the Z32 uses this line to drive the FICD (Fast Idle Control Device) – for idle up when aircon is on. FICD is driven seperately on the R33 Series 1 RB25 via the aircon system. Note that the R33 Series 2 RB25 does use the FICD the same as the Z32 ECU, so this modification is not required for those engines

Anyone know what might be causing the exhaust temp lamp to be coming on or If there was some series 1.5 r33's that run the series 1 ecu but have series 2 bodies etc produced in early 96 or something?

Is there anyway to tell whether its a series 1 or 2 ecu with the serial numbers on the ecu?

Are u sure ur car isnt a series 1.5. R33 are tricky when it comes to z32 ecu.

Will be easy enough to sort out mitcho.

Does the car drive or is it in limp mode?

Seems to drive fine, I took it around the block and it didnt die on me or anything, but that was only a quick spin so im not sure.

How can i tell for certain what series it is? Certainly has the series 2 front bar and rear wing and a passenger side airbag that much I know...

Does it have another check engine light? On R32 the exhaust (catalyst) overtemp light is the check engine light. When it is on 100%, it is the ECU advising that there is a fualt code to be read.

Mine is on right now because the Neo ECU and engine are happy, but they're not happy that the traction control stuff is not present. Connect with Nistune, can see exactly those fault codes.

You might have a sensor fault or something rasing a code.

Does it have another check engine light?

Yeh above the cat temp light is the check engine light which isnt on.

For the time being i have dissconnect the z32 and put my r33 ecu back in, but I still want to get it sorted. I have contacted matt at nistune and he has said it seems unusual, especially if my car is a series 2 as I thought.

From what I understand only 95 R33's are S1.5, anything 96 onwards is a series 2. The S1.5 had a series 2 engine. Im about to put a z32 nistune on my S1.5, hope I dont have this issue.

Correct.

don't worry about that light it should only read a resistance value from the sensor, I haven't seen it effect anything, didnt log codes or jump maps so I just cut the sensor out and disconnected it under the passenger seat, and i didnt get the light anymore, the only thing you should note is whether you have an igniter on top of the motor, if you do series 1 if not series 2 running gear

So u have had the same issue with yours?

There is different ecu mods for each model. And Matt would have modded it to series 2 as u told him.

Few Q's.

Have u tried the A/C to see if the engine idles up?

Is there an ignitor on top of motor at the back?

Yeh, I tried the a/c with the z32 plugged in but because it was cold, it was idling fairly high anyway. The car didn't die went I put on the a/c. If its a series one, the ficd is done by the a/c separately isn't it so shouldnt it work regardless?

I'll go have a look for the igniter on the engine and get a pic now.

    • Have a vb in honour of the car comming back
    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
