Hey I thinking about doing something with the ECU on my 200sx soon . The trouble is I am undecided on what I should get , at the moment the car only is running mild mods such as turbo back exhuast and an air filter and I have also installed a bleed valve and the car is running around 14psi . The only mods (for a long time if I still have the car then even) I am planning on doing to the car in the future is a FMIC and maybe get the turbo high flowed or a bolt on replacment turbo. I am sorting of thinking of getting a apexi S-AFC do you think this would be a wise decision?. What about a unichip what that do a better job or maybe I should just look for a second hand microtech how much would it cost to install an mt8 drive in drive out?.

7HEAVEN,

If you do a search, there are plenty of posts about Unichip vs S-AFC. Only disadv. with the S-AFC is it doesn't do timing which the Unichip does. Then again you will need to go to a Unichip tuner everytime you need a tune which costs $$$.

Note: I wouldn't be running 1bar with the stock cooler unless you want you car to start pinging. Just a thought :)

if your after a aftermarket ECU then PowerFC is a good option. else if you meant to say interceptor then the UniChip is the goer. or maybe u want a piggy back ??? then Chiptorque unit is the goer.

my personal option is the ECU.

go the power fc

on an s14, the power fc will even control your factory boost control solenoid.

Heard good things on the Unichip but yeh the PFC would be the ultimate...I will be getting a Unichip for mine when the time comes though as it is all I really need!

PS - I have switchable boost on my car and have run up to 16psi without even the slightest pinging although I only run it on cool nights and not for extended periods (in Brissy so it is not always cool and don't run on hot days)...but yeh over 12psi will kill the car in warm/hot weather and if you run too high boost for too long.

forget interceptors, they are band aid systems, go for a full replacement aftermarket computer(i can reccomend some depending on budget,features,etc that ive had experience with)upgrade your fuel pump and injectors and youll be happy !

I agree with syn.13b. If you can't tune it your self I would go with the one that your workshop can tune, cause all too often peole say this is better then that, but it all comes down to the ability of the tuner. For example, I haven't heard alot of good things about the Power FC or EMS etc. on the Gold Coast because no one can tune them very well. So it makes little sence to buy one on the coast just because Sydney cars are having success with them, as your not going to drive for hours to get your car tuned.


Just a thought......
