Hello
Has anyone wired a HKS Fuel cut defenser in their car. If so, i`m in need of some help...i have tried to contact the Hks web site but seem to be having no luck, please help
thanks,
Andre

 

Ive never heard of any one using ity pon an fd, Its popular with the fc crowd, try there.

 

Very bad idea to use it with the FD.

 

Explain Rynberg or show us where to read about it. You can't just say don't and leave us hangin!....That's a teaser!! ( I've heard this before as well, but noone had an explanation then either) Does it conflict with the ECU or something?

 

All the HKS fuel-cut defenser does is tell the ecu that you are running a lower level of boost than you are. So, if you are hitting 10 psi, the ecu thinks you are only hitting 5 psi, for example. Since the FD ecu uses fuel/ignition maps that depend on the boost level, you are essentially running the wrong fuel/ignition maps at all levels of boost.

The FCD works with an FC because the FC uses a mass-airflow meter for fuel maps, instead of relying on a boost reading. Therefore, the only thing you are changing with the FC is the fuel cut-off point and not the fuel/ignition maps.

So in otherwords, DON'T use it on an FD. For chrissakes, go buy a friggin $400 Pettit or M2 ecu! If you can't afford that, then leave your friggin' car alone!

 

Easy does it boy!! Down, Down!!. It was only a question. I understand how it works just fine for the FC. I have only heard people say don't with the FD and wouldn't since it already has fuel cut at a higher point than needed to run safely. ( Not to mention that my car is already full standalone crapola PFC , soon to be haltech.Single turbo etc..., Just take a deep breath and relax for chrissakes)The question was more for an informative explanation from someone that is relativly knowlegdable about the reasons why, So that there are not a million more posts asking the same question. Sorry to have inconvenienced you.

 

Sorry for the misunderstanding, my last paragraph was more meant to those people who are trying to ghetto-mod their FDs and not to yourself...the basic problem of the internet is that emotion is often hard to discern...

 

True that Rynberg. No offense was taken here. Hope I didn't offend.( I was just giving you ****. ) Anyways thanks for the explanation . That is what alot of the people need to see....The facts! Thanks again, Aloha, Dave
