Using an AF ratio meter on our Porsches
Hi guys. As checking AF ratios follow a good rebuild, I thought this might be a good place to query AF ratios.
I purchased a MoTec PLM (professional lambda meter) today so I can measure AF ratios on my 993tt engine. The MoTec only has one sensor and my engine has two separate, independant exhaust piping. How do I measure each side at the same time?? The easiest way is to purchase TWO MoTecs, but at better than $1,000 each I find it hard to do.
Do Porsche owners usually measure one side at a time? Is there a lamda sensor (accurate) that can take two sensors at a time?
