I spent lots of time tuning my Bosch MFI [mechanical fuel injection] on my 1973 911 Carrera RS tribute.  Various forums, primarily Pelican parts were key to my education.  I found out VERY quickly that I needed a good way to know what my Air Fuel Ration or AFR was in the engine.  Maximum efficiency is 14.7:1 ratio of air to fuel.  13:1 is good for best power.  Modern instruments now have wide band oygen sensors that are quite accurate and very fast to react.

 

It is one thing to test on a dyno, but what you really need is full time, permanently mounted monitoring that also has the ability to record data so you can analyzed it later.......pretty tough to remember what RPM, load, etc.  for a certain reading.  Ideally you monitor AFR, vacuum/pressure [or MAP], and RPM.  fter a lot of research and testing I found this Daytona-Sensors WEGO unit that satisfied all of my needs in an accurate, rugged package.  I permanently installed it on my 911 and tuned the MFI to excellent performance.  I have a dash readout in front of me and the ability up to 2 hours of data by plugging into the front panel micro USB connector and downloading the data to my laptop.

WEGO™ Single Channel Air/Fuel Ratio Display Systems with built-in data logging. These kits include the WEGO™ unit, Bosch® LSU4.2 5-wire wide-band oxygen sensor, 18x1.5mm weld-bung nut for mounting sensor on exhaust pipe, and our software on CDROM.

 Also available in dual readout unit with 2 sensors.  See our other listing on this site.

WEGO™ units are versatile tuning aid for all carbureted and fuel injected engines displays air/fuel ratio (AFR) and logs over 2 hours data including AFR, engine RPM, and a spare 0-5V analog input for sensors such as throttle position or manifold pressure.

WEGO™ systems are highly accurate with less than ±0.10 AFR error over 10.3 - 19.5 AFR range (±0.007 Lambda error over 0.70 - 1.33 Lambda range) and feature a ‘Easy Free-Air’ calibration procedure corrects for sensor aging effects.

WEGO™ units feature a wide supply voltage range from 11-16 VDC allows operation from battery on small engines and race vehicles without an alternator. Current drain is approximately 1 Amp, and includes a built-in USB interface.
