So what happens when your o2 sensor messes up? Or gets fouled out for whatever reason?
BOOM!
Edit.... I just read that it uses the stock o2 sensor. Good god.... That's a bad idea.</TD></TR></TABLE>
The stock o2 is a wideband from the factory
And I guess, If your o2 sensor goes bad, your car will run like ****
Just like it would if it were on a car running hondata or any other EMS.

Re: (Sohc Driver)
I read a thread that cybernation made last night.
If I had an RSX I'd never even think about using their guardian.
Go look at their website, not very professional. Constant spelling errors and inconsistancies.
What about their 500whp integra running 440cc injectors?
Lots of EMS systems have autotune funtions and the general concensus is that they arent the best route to go.

For those who missed boostage's thread
Im not convinced one bit

But the stock EMS doesn't vary the fuel load a whole lot based on the o2 feedback, it still has programmed in values and an allowable range of adjustment that the o2 sensor feedback will not exceed. If the Guardian is always tuning, then it's going to start changing all of its tables, since it's impossible to have some tables that are set and never changed on a system like that. It will change values a lot more and over a bigger range, since all the Guardian really is is an auto-tune enabled fuel map using the o2 sensor. The AEM does not always retune itself, it sticks to values input by the tuner and then (if o2 feedback is enabled) will alter the fuel load a small percentage based on the o2 sensor's readings and the range the tuner has specified.
Also, has anyone does any kind of respose testing or reliability of the stock RSX "wideband" sensor? The previous Hondas that came with a wideband from the factory, the sensor was not nearly as accurate or as quick-responding as any aftermarket wideband sensor.
Guardian also says that this system will work on any Honda/Acura. Most Hondas and Acuras do not come with wideband o2 sensors, so they'll either have to upgrade, or the tune will always be inaccurate.
