best ecu/tuning options for rb25

[rs73]

Greddy E-manage would be another cheaper alternative to PFC. But it's still not a full ECU replacement, it's still a piggy back type just like SAFC, however with the extra ignition timing control, etc. Compared to PFC there would be slight disadvantage as it is only intercepting the voltage signals to the factory ECU, so it's still has a limit up to a certain point.

But for ppl with auto gearbox, seems like Gredddy E-Manage is a popular choice as it's the one of aftermarket ECUs that will work with autos.

I would tend to lean towards the new Unichip instead of the E-Manage.

Much more support here in AUS + it can apparently now do some pretty fan dangled things that so I was told it has enough adjustment that you would not require a full replacement ecu.

I doubt it to be honest.

does unichip use piggy back unit like wolf3d or a chip replacement like powerchip do?

Reading all this info is pretty overwellming, I've had a look on EBAY and found the following items for sale:

* Greddy Trust Emanage ECU $449 and

* APEXI S-AFC II Digital Super VAFC $429.

Would these systems be OK for a RB25 Skyline,

The feedback would be appreciated.

Those items would be ok for rb25 skyline.

but for $20 difference, better go the e-manage as it got more function than safc
