will i need A/F sensors and box

Hey guys if im going FI, and purchase the blitz touch brain or any reader, will i need to purchase an O2 sensor cable and sensor box to hook it up to the system for it to read the A/F, or can i use the existing O2 sensors that are alread on the car to hook it up to the reader, the sensor and box cost something close to 600$ so im hoping that i wont need to purchase that part.

This is something I ran into as I have gauges that read the factory O2 sensors.....

The factory o2 sensors are not true widebands, and therefore I would recommend an aftermarket sensor.

Depending on the system (i don't know blitz at all) i chose to go with the innovative lc-1 as it has a 5v out that will work with most digital gauges/systems

Ohh ok thank you for the advice so I should buy the extra a/f box, can you please show me what you are running to monitor you af bosst etc

factory sensors are wideband. I am reading them through obd2 using dashcommand and when comparing the readings to my innovate mtx-l they are very similar if not the same. I keep the actual gauge on the glove box just for peace of mind but I mostly go by the stock sensors.

What happened to the JUN cams?

So there will be no need to purchase the a/f box ?

Depends on the system you go with. Blitz R-VIT DS does not require additional sensors to read from AF from OBD2. HKS Camp 2 does.

What I do, like mentioned above, is read AF via OBD2 using DashCommand installed on a CarPC and keep a standalone AFR gauge on the glove box.

What about the blitz touch brain? Vit ds has been discontinued

Looks like it should work without any additional sensors, you will need a sensor for boost though.

Thanx a lot for clearing that up bro, what about boost sensors I'll deff need that right

Correct, you will need additional sensors for anything that OBD2 doesn't provide. Boost, oil temp, oil pressure, fuel temp, exh temp etc etc.

Cool thanx Ron for your help, don't our cars already read oil temp? Will I need all of that for FI?

It does read it but it is not an OBD2 parameter, there is a separate sensor for it. I am still using the stock gauge to monitor oil temps.

Thanx man a lot, so a/f reading and boost should be enough for starters and can get everything later on, thanx again bro for clearing everything up rep coming ur way:D

Anytime man :tiphat:

This is what I am monitoring on my system, plus oil temp on the stock gauge:
