Hey everyone ,
I was pulling my travel trailer ( 6500 lbs ) and was seeing absolutely abysmal mileage. I quickly got a cruise log and seen my timing was super low . Its not a great log , as I didnt have time to set the parameters. The only thing I can see that would cause this is ECT timing .. as I was running warm ( 230 C ) and the ECT table shows -50 deg fro 250 C ... So my question is... does anyone ever modify the ECT Table so its not so aggressive?? I tow with 91 oct.
Attached is the crappy log and the tune I am currently using. cruise with trailer low timing.hpl87 performance.hpt
