which ecu piggy back, 3rd gen st205 Options

[CELL_PROTOTYPE_X]

I'm trying to decide which piggy back to get. I'm thinking of getting the apexi afc neo, but wanted other suggestions and or reviews of people using this. Any info would be nice.

Insanity-74,

By plug and play, I was referring to the installation process of the ECU, not the ability to plug it in and go flog the car immediately. Any aftermarket ECU other than a re-flashed stock unit like the Mines or Blitz tune will require some sort of setup.

The question of the intercooler pump wiring isnt a concern at all, since you would only need a simple on/off curcuit setup by a 4-pin relay. It would probably be more difficult to setup an aftermarket ECU to switch on a pump than it would be to just hook up the relay to the battery for power, 12v to the pump, COR for switch signal, and switch ground.




The Hydra Nemesis setup sold by KO Racing comes with a fully re-pinned breakout junction box (seen in the picture I included) that matches all the stock harness plugs on the 3rd gen 3SGTE ECU, so it most certainly is plug and play. They also include a base map for the 3rd gen on a CD so you can upload the basic parameters to get the engine started....no mapping issues, just a visit to the dyno to tack down some good AFR's and timing.


Apexi included a pre-wired jumper harness with their Power FC units for the ST205, so theres no wiring involved unless of course you choose to run things differently yourself. Only difference with that ECU is that you need to enter the basic engine parameters on your own on a laptop to get the engine started....i.e. displacement, timing advance, turbo or non turbo, etc.


Either way you'll be able to plug your three factory ECU plugs right into either unit via a pre-wired harness, and get the engine started without too much hassle/mapping of your own. However you will obviously need to pay a visit to the dyno to get a good tune before you go boosting.




I think the biggest factor with tuning is this.....if you get a reflashed ECU, you will have to send it overseas to get it setup and tuned....meanwhile, your car is halfway around the world and the tuner really can't truely dial in what is ideal for your car because he's nowhere near it. Each car is different, so the tune you recieve will only end up being a very educated guess in the end. If you use an EMS that is domesticly available and that tuners in your area are familiar with, you will be able to get a great tune that is ideal for your car, and your car only.


At least thats how I see it.
