fla 9 Posted December 26, 2016 Ive converted my car to obd2. I think the original fpr was 4bar but the obd2 was 3cbar or 3.5bar, although this was for a 2.8 engine. If i replace my fpr what pressure should be used? 4 bar? Thanks Quote Share this post Link to post Share on other sites
science 0 Posted December 27, 2016 The ecu can cope with 3 or 4 bar, but 3 bar seems smoother probably from longer injector timings. Sent from my iPhone using Tapatalk Quote Share this post Link to post Share on other sites
