Old school datalogging

Update by Per Schroeder to the Nissan Sentra SE-R project car
Mar 24, 2005

According to SR20DE gurus Mike Kojima and Clark Steppler, the air/fuel ratios that we’re seeing on the Dynojet are invalid. So, we welded an oxygen sensor bung onto our header to see how the a/f curve looks on our Innovate Motorsports wideband. You can see there’s quite a big difference at full throttle around 4000 rpm, at least a half point, the differences are similiar across the board. Further buggering up the typical sniffer type A/F ratio testing, our car still has a catalytic converter, which acts as an oxygen source.
