I asked this in the engine management section but there's not a lot of people browsing that section or any help. I got the ecu (its the silver one not the black old style unit) with the correct harness and boost sensor. All I want to know is do I need to buy any other sensors or anything to install this ecu into my car? And can I use it as a stand alone or does it have to be piggy back. Remember it's the F-CON V (not pro)(silver case not black). Also what needs to be done to it after the install? It's used so it needs to be retuned, do I have to send the rom out again to get retuned or can I use a dial that would be inside the case like the black unit? Or do I have to go get it dyno tuned by an hks certified dealer? I already searched with no help about what I want to know. Thanks in advance.

 

To my knowledge you just need a harness for the FD3S. This is supplied by HKS. You don't need any other sensors as it a piggy-back and not a stand alone ECU so it will retain all the factory sensors. I don't know about the USA but here is Singapore HKS tuners have a special software to tune it

 

You can tune it yourself also but you have to buy additional units for fuel and one for ignition, not worth it IMO.

 

Ok, I know I can buy the GCC for timing and fuel...I think its for timing also. But what can I do besides that? I don't want to buy the GCC and this ecu is just temporary until I can afford a PFC again. Can I go to an HKS certified dealer and have them tune it? Can it be tuned while its off the car or does it have to be dyno tuned?

 

anyone wanna help me with the above question?
