Skip the narrowband, and put the money towards a wideband. You can have one for around $250, and it will actually give you useful information.

 

Honestly with an 88 NA and no real way to tune it, the narrowband is the best bet. It will let you know if the engine is basically lean, or rich, or in closed loop. And they are all the same so buy whatever you like or whatever is cheapest. Now if you have a way to tune the car, then a wideband is the way to go because it is the easiest tuning aid.

 

A narrow band will probably work better on a rotary than what it does on a piston engine.

Just for example, my old truck had a narrow band on it and it would go from full lean to almost full rich. It didn't tell you **** really except that the engine computer went from lean to rich for the catalyst to work efficiently. As far as I *Know, the rotary doesn't do that, since it can't afford to go lean at any point. Still, it is a narrow band and will give you a basic idea.

* = denotes that I do not know for sure. Observation based on understanding of fuel delivery on the 13b NA.

 

Nah, a narrowband gauge on a rotary will bounce back and forth between lean & rich while metering to 14.7 AFR (O2 sensor input active). There's no difference from a piston engine. That's really the only thing it's good for though; trying to stay in closed loop for gas mileage. The lean and rich zones are so crude that on mine, for instance, each LED represented a 1.4 AFR point range. It was an autometer narrowband w/ 15-20 LEDs.

 

going wide band but just dont know what wide band to get. there are so many i dont know which one is good,

so give me some ideas and tell me how you like yours...

 

Innovate LC-1 is one of the best, and is widely used.

 

I second that.I have the lc-1 and love it

 

I had the Haltuner, its a pretty fancy light show, thats about it.

 

AEM Wideband... Best Bang For Buck.

Here's a Link.

Or just Ebay...

 

I have seen nothing but problems with the Innovate widebands. They seem very behind the times.

I've always preferred the AEM UEGO. It has always ranked highly in reviews, it seems accurate and responsive, and the price is right.

 

Really? Mine works perfectly, and the AEM unit frequently has complaints as well. Ask Arghx how much he liked his . High failure rate and poor customer service seems to be the trend.
