Hello everybody, today i received a UEGO AEM wideband/AFR Gauge, model 30-4110. I have a stock ECU in My 93 NA miata; I have a megasquirt pnp on the way in the mail. I have done a lot of research and still am having trouble understanding the instillation. If i do install it how will It communicate with the stock ECU and if i do install it with the stock ECU and i upgrade to the megasquirt will I have to do additional wiring. From my understanding when some people do the stock ecu install they splice the blue wire into the stock ECUs wire and switch the gauge to the P4 mode. I know im just a newb when it comes to this stuff thats why I am seeking further understanding thx for the help/advice.


Also if anybody could link me to any helpful videos or forums feel free too

 

I wouldn't use it with the stock ECU. There's really no advantage to doing so.

 

already put it in lol, didn’t have to many issues learned a little bit, it runs a bit choppier now , just waiting for my mspnp2
