Hi guys,
Since I bought my e30 (325i with m20b25) I've known it was running rich, but didn't know how bad it actually was. Installed a wideband sensor today (planning to put it on megasquirt in the next couple months) and it confirmed my suspicions. At idle (fully warm) it sits at 11:1 or lower, and stays around 11 - early 12s under acceleration, sometimes lower, never higher. Even just cruising in gear off the throttle it is about 12...
Car has 288 Schrick cams and larger injectors (which I thought were 19lb/hr, but might be higher) running on stock motronic. As said I do plan on putting it on megasquirt standalone soon so should be able to tune it properly then, but just wondering, is there an easy way to make it run a little less rich in the mean time? Would it just be the larger injectors causing it to run so rich, or would it be something else? My fuel consumption is absolutely horrendous, and running this rich can't be good for anything, so I'd like to sort it out
Cheers
