    Heater blower doesn't run

    Engine runs very rich

    Did it today in close loop: at idle BL is 126, then went after start in different driving condition to 124/123/122/125 and 128 on wot. Made test on third with wot but only saw O2 at 693. May be have to do last test again.

    Engine runs very rich

    Set fuel pressure on 38 lbs and use Scanmaster for tune up. How much miles should I get with the 60lbs injector by proper tuning?

    Engine runs very rich

    Hi, only for understanding and maybe I made a mistake when I made the tune up of the engine. My engine is allways running very rich whether I use close or open loop. Performance is okay, but I am not shure it could be more if it would be running leaner. What was done on the engine, you see in...
