Subject: Re: How often do you calibrate your wide band...... by mseven on 2010/11/27 20:57:27 Mike, Sorry this took so long...I ended up looking at it this morning before work. After reviewing the screen shots and the excel it appears that you are roughly at .915 (n.b. 02 m.v.), and I would consider that safe. However, entering wot could use a little more fuel (a tad lean I would add ae/pump shot, or at the table). Bank to bank the one side is a tick low/lean 878ish/915 and I would work that area a little more (add fuel). The timing hitting 38* up on top may cause a small amount of power loss instead of gains (not to mention potential detonation). When you actually dyno it you will probably end up around 34-36* max. As to innovative lm2, since I believe you calibrated per their instructions, a couple of possibilities cone to mind. Possibly a pin hole leak at the bung weld,(leaks in general near the sensor), or the lm2 needs to be re-calibrated by innovative. Another test you can do is to clamp/install the 02 from the LM in the tail pipe. If the readings are still not lining up than I would contact Innovative and let them re-calibrate or check out the unit. BTW...you don't need to wring out the rpm that hard for testing..LOL hope this helps, Mick |
