Rb25De+T Ecu

[getrichster]

Hey I bought a r33 series 1 rb25de+t and it is running the factory de ecu. Ive googled it alot 50% say a series 2 gtst ecu will work, 50% say it wont work. Its really hard to find a r33 gtst series1 ecu and have found a series 2 gtst ecu for cheap. Anyone actually run a series 2 before?

It requires a Nistune ecu and a touch up tune on the dyno as a minimum.

You also need DET injectors if you don't already.

For the de ecu? Can't I run a det ecu and remap it?

[kitto]

Yes but you still need a Nistune capable ECU. R33 ECUs do not accept Nistune and therefore cannot be remapped.

You need a Z32 ECU modified correctly to suit the R33 RB25 with Nistune so it can be remapped.

look harder, i found a S1 R33 ecu on ebay for $70

To add: If its a non VCT RB25DE, you can simply get away with using a Nistuned RB20 ECU

If it has VCT youll need the Z32 ECU.

That's not strictly true, because it is trivial to add a window switch to run VCT while using R32 ECU to run the rest of the engine.

The option exists.

Yeah I know about it. But explaining it to some people on the other hand can be a challenge.

Most people just think VCT is shit and decide they dont need it.

MSG toshi on here could possible remap your original ecu

But best to upgrade your injectors and afm as the std de items won't get you far

[getrichster]

Already got yellow 440cc injectors in, unsure of brand. Afm is a pink which I heard comes in a series 1 gtst? Wish had a nz version of toshi. Coming over for New Years so will be buying up parts big time. Cheers for the help
