HI All,

As title states I bought a r33 gtsts manual conversion and it came with this ecu, Not that I plan to use it was just a bonus thrown in but I am interested if anyone can identify it the blue heat sink looks to be either not original or someone has played with it or just Nissan are shoddy with there work.

Has very neat hole cut in it but from my knowledge if a nistune board has been fitted it is the aux board that the interface clips into not where it has been cut to expose the lower board pin like this one has.

Anyway if anyone can shed some light from the part numbers ect I am more curious as the guy I bought the conversion of is adamant the car went (he has no reason to lie as I bought gearbox not engine or ecu) and it looks nothing like my r33 one when I opened that up.

Cheers lads and ladets

The part number on the lid is correct for R33 RB25DET MT ECU. But the mainboard inside does not look like an R33 ECU. There are two big square chips in the middle of an R33 board.

That board looks like some aftermarket plug in style ECU rather than a Nissan one.

Thanks for that GTSboy it has me miffed as a lot of it looks identical to mine when I opened it up but the alloy side bit has a hole in it with a + and - and hole that looks like you turn a dial but in the ecu on the card there is nothing to turn.

Well anyone else able to help me with what I have ?

If there's a screwdriver hole with +/- on it then it is possibly a case (at least the bottom of the case, not the lid) from an earlier ECU. That was the idle speed adjustment on R32ish era stuff. I don't know if it was still there on R33 ECUs because I haven't really played with them (why would I? They're only good for paperweights!).

cheers

na it doesn't have it on my 33 ecu I am mainly curious as to why there is the cut out like you can hook up to it as its in the wrong spot for anything I am familiar with.

I also did a google images of Z32 240sx and r32 stuff and it doesn't match any images I could find the car it came of was fairly stock as in still had low mount manifold ect so I cant see why it would have any weird ecu in it

Well the plot thickens I figured if anyone knew what it was itd be the guys at Nistune Matt confirmed the sticker same as GTSboy and that the case witht he + - same but the inside he had NFI and stated he had never seen anything like it before it actually runs the car all be it rough as I have a few mods that a stock ecu would run rough on to.

SOOOOO now that even the experts don't know what it is I actually care and want to know (yes curious) before I throw it out lol

Got a 6 pack riding on an answer will drop of to anyone local to me 3804 and I mean local not a hour each way

Winner. Different numbers on the board though. The one in the ad says GTS280 and this one says GTS49, and there is no link sticker on the chip. So maybe it is either an earlier version or perhaps there was some renaming of some other ECU involved in the genesis of the Link G1.

Yea HR32 you were in first with right answer, I figured it out the night I posted this up as I removed back of the cover and it was just written there it is a link g1 gts ecu ive checked numbers and she is fully programmable.

I am however looking for a link serial link so i can play with this on me dyno so if any of you have one sing out i only want to borrow it so i can copy it and return.

Sorry everyone but no chance id throw this little gem away and the best part was i got it thrown in with a manual conversion i purchased and the guy said and i quote "here you can have the ecu its got a hole in it f**k knows what that's about" i knew there was something about it one doesn't just cut a hole in there ecu

On a different note Matt aka HR32GTS where are you located as i may have to drop a sixer of as a promise is a promise.

      Gates is saying the same thing. They think I have the right bag with the wrong hose in it... I bought it off amazon, I'm thinking someone pulled a good old swapparoo and returned normal hose. Well looks like she's coming back out... Not very lucky with this hose lol.

      Chatting one someone recently at racing them at QR. They say you can't take turn 2 in one flat stick in 4th. They don't have the torque to pull them selves straight, so make sure you're ringing it's neck out in 3rd instead

      Should you buy cheap Chinese tyres?

      By MBS206 · Posted

      Many years ago when I bought my FG XR6T, it came with bald tyres on the back (think pretty much smooth for most of the tread) and brand new Kinforest cheap shit tyres on the front. In the rain, I had more grip in the bald ass tyres on the back, than the brand new Kinforest. To the point you couldn't drive off at a set of lights and turn the corner. Car would only go straight. Very quickly all four tyres were replaced.   A few years back on a VF SV6 I had, it came with brand new chineesium tyres. In the wet at 90kmh, old 1990s tray back tradie utes could corner faster than me. There was one corner on a freeway, in a 90 zone, it's not even marked to reduce speed for those curve, it's not a hard corner, I could put the LandCruiser on mud tyres through with ease (it would easily do the corner in the wet I reckon at 120kmh), the VF however couldn't get through it at 80, as it would want to slide out.   Cheap tyres aren't worth the risk. I like decent brakes, and decent grip.

      Anyone here a submersible fuel hose expert? I pulled my hanger out again for unrelated issues and noticed the hose I popped on last week has already swollen. This is Gates 27093 submersible hose. I've waiting on a response from Gates, but this surely can't be normal? This is on pump gas, not E85.  Is swelling a tad possibly normal? I've also been fighting with my power steering belt.... I've now tossed one and killed two. I just realigned my pulleys again, hoping this time it stays on. It doesn't like high rpm.
