Arron 226 Report post Posted April 6, 2016 had a exuahst leak develop last race meeting and thought it was a flex joiner.... sadly we were wrong we have discovered that the o2 sensor from the front set of extractors has blown out of the manifold and dropped onto the track so we no longer have it do any of you have one tucked away??? we need it asap as we are racing on sunday Quote Share this post Link to post Share on other sites
hybrid 1040 Report post Posted April 6, 2016 Just a side note: for MSS50 you dont need the o2 sensor for wide open throttle operation. I would just pop a bung/bolt into the boss in the exhaust on both sides for now an remove the other remaining sensor and tuck up the wiring.You will have slightly more fueling in the part load zones however it will be fine for racing. Its really only a concern if your worried about economy in the short term which I would say you wont be spending enough time in part load zones for it to even make a difference. Your long term fuel trims will need an adpation reset after you replace the sensors for the ECU to make proper effect of them as ever sensor is different.
