Is it easy and/or inexpensive to get the factory ECU remapped to suit a couple of mods? (air pod, bigger turbo, more boost, etc). If so, would there be any use of installing an S-AFC? I know it's better to get a fully programmable ECU like Power FC, but depending on the cost it might be cheaper to re-program the stock unit.

Ah, so that's why people buy R32 ECU's and get them remapped then. Where could I get an R32 ECU from and how much roughly? I'm guessing then that things like the S-AFC are only around due to the R33 not being able to be remapped.

It is possible but what you need to do is solder in a daughter board (extra board) into the ECU.

This get's rid of the ROM chip and replaces it with a writable chip.

There was/is a fellow on SDU that is gunna make up a heap of boards - check in the For Sale area.

As Meg's said, you can use the R32 ECU but you'll loose your VCT stuff (The R32 hasn't got it).

Cost wise I still don't know how it would work out. I sent a quick PM to a fellow in Sydney that has done it (can install/program/tune) but I'm still waiting to hear back frm him.

Ah ok. Well eproms are cheap, unless they use some weirdarsed non-standard version. I could do the soldering myself as long as I had all the right bits.

So that would leave the majority of the cost down to the reprogramming itself.

If you get a R32 ecu and send it to me I can remap and modify it to run variable cam timing the same as an R33 ecu. I currently have an r32 ecu in my 1995 r33 gtst, factory vct swithces off at at 4800 but i can set this to any rpm or intall a switch for different rpm switch off points. Cost is $175

Jay your PM box was full!

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
