I found a electric Afr automater phantom guage for 30 bucks he will take 20 should I do it?

 

no, its not a wideband and it is not worth wasting $1 on it

 

yea, taps into the factory 02 sensor wiring and is only a 0-1v reading.

get a wideband

 

stay away from it, even if it is free, installed a narrowband a/f gauge after i built an ashtray pod, wired it up to test it - was a mistake - had o2 faults, unplugged it and now all is well. best is wideband as mentioned

 

You had o2 faults because you installed it wrong-^

But yeah, stay away from them. Pointless.

 

Narrowband A/F Gauges are basically just really flashy ricer lookatme gauges. Get WBO2. I own a dsm and can afford one surely if you can afford and evo you can afford and accurate tuning device.
