Would it be worth it to buy a pricy wideband gauge/kit for fine tuning a 13B running a 48 IDA?

 

yes.

 

Much obliged...nice 7 by the way.

 

Get an LM-1... at 350 bucks.... not pricey at all... my DAD wants to borrow my wideband (and me to tell him how to use it ) to dial in his 67 cougar!!!!!!!! A/F is A/F my man..

 

350 for just the sensor, or with the controller?

 

$349 with everything https://www.rx7club.com/showthread.p...2&page=1&pp=15

 

www.plxdevice.com i'm running the m-300. 300 bucks comes with everything and plenty of wire lenght. big giant display of your exact af/r. and really no matter which you get, you can not truly tune without a wideband. so this is a step in the right direction for ya.

 

man thats too much for a o2 sensor and gauge dont u think i dont care how many wires it is

 

****!
Imagine back in the 90's I paid between $1500 to $2000 for a wideband!

 

But for afr tuning purposes, wideband is the only way to go, especially on turbo cars. Because the factory narrow-band sensors ($30) last i saw, are only meant to read around stoic.
