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

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
