Question Greddy A/F Guage Compatibility with Link2?

I didn't like the Bosch o2 thing. I honestly think it was a waste of money because my readings are just as unstable as the stock o2. So I broke down and bought the Greddy 60mm A/F guage. This is actually a really nice piece because it comes with greddy's own proprietary o2 sensor. It can work as a direct replacement and still send signals back to the ECU. However... I'm unsure as to what the signal outputs back to the ECU would be. Has anyone tried using this with their link? I haven't looked into the factory forced induction forum to see if anyone there has tried this either.

I have the stock ECU in the car right now since my laptop took a shyt. I want to get the Greddy guage in so I can take the A/F values of the stock car and implement it when I get the link back in.

Er.. if tuning the car keeps going like this. My turbo will never get put in..

How many wires does it have?

You can go to ravensblade and look at the wiring specs for your RS. If the O2 you are replacing has the same voltage range then you shoudl be all set.

The GReddy is a special near-wideband sensor that reads 0-5V and is MUCH more stable between A/F ratios.

I don't know what the voltage is from the output on the unit... maybe take a voltage meter to it and see what it says? I know that the Haltech can take a 0-5v (1-5v?) sensor instead of the standard 0-1v, but not sure if you can change that option in the Link.

No that won't work on the Link Plus. There is no wideband O2 feature as of yet.

That sucks. Is there a possible future software upgrade that will allow this? Or would this be a possible hardware issue?

Realistically you could use a potentiometer to cut the voltage to 1/5 of what it normally is and input that... but you'll still have the problem of teaching the Link a new A/F curve depending on the new sensor's range.

It's actually a 0-1V sensor and it's not that close to being accurate. Check the Proven Power forum, they tested Greddy agains a real wide band and Greddy read 2 full poinst lower!
Knock City. I think it was the dyno with a VF-34 post.

On the other hand, there is this testimonial in thread http://forums.nasioc.com/forums/show...hreadid=186509 from RiftsWRX about his Greddy A/F meter:
