R33 Factory ECU remap.

[JimX]

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.

32 can be remapped

33 haven't heard of it being able to be done.

[JimX]

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.

the r33 ecu can be remapped I'm looking into it .

also I'm looking into useing the r33 ecu but you loses the vvt.

powerfc is a better option if you are chasing big hp.

I have an R33 GTR computer remapped and 2 maps which are switch selectable.

So it can be done, but mine was done in japan.

Does the GTR have the same ECU as a GTS-t? Shipping the whole car off to Japan isn't really an option though

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!

[Guest Joe_Tomarchio]

at what different rpm points can you turn the cam off at. does this make much difference?

[Jay95R33]

TurboGTST - sorry dude. Damn I need a bigger mailbox

That sounds pretty good to me. I'll have to keep you in mind, plus maybe a tune
