I was just looking at Tephra 7 and it says it has some AFR safety features etc. in place

If I was to configure Tephra 7 to run with an AFR sensor and MAP sensor so that I could log accurate AFR and Boost, assuming all safety thresholds are set, is there any real issues/tuning limitations? I understand that I won't have an AFR/Boost gauge to physically see but is that a real problem?

Basically I want to spend as little money as possible so I don't want gauges if I don't really need them.

 

You would at least need this.


AEM

 

Or can use zeitronix or innovate and still do the same thing.

I ran my car without a wideband display gauge for almost 7 years. You will be fine doing the same just make sure you do not have any leaks in the exhaust system pre-wideband sensor.

 

Anyone know if I can use an Innovate MTX-L and log without a gauge?

 

I always map without any gauges.. esp on tephra V7 which will flash the CEL on knock..

 

That's what I'm planning on doing

 

Gauges are not needed, knock light and are saftey will work fine.

 

What your describing is how I'm running right now. I don't like the look of gauges inside so I just plug in and log every once in a while to make sure everything is running right. But when things go wrong you can usually feel it in the engine anyway.
