I am planning on putting a Megasquirt into my RX7 and was wondering if I need to budget for a wideband setup also?

Thanks,
Bill

 

To do the job properly with real time o2 correction yes, you could get it running by feel, but that would be hard for someone not experienced.

I bought one, and I used it everytime I tune + once the car is running properly you will use it for fuel correction.

 

It's not required, but definitely a good idea.
