ZZ4 MPG Challenge II
Vacationing from July 24-August 2nd. BADBOW is going on its second major trip. The ZZ4 now has 6000 miles since being installed. I may even hit the strip too! It is getting a custom hitch installed for the roll pan. I managed 18.5 MPG out of the ZZ4 after a few adjustments. I'm going to see if I can squeeze 19 and still do 70 MPH!!
Any suggestions for improvements? I'm thinking of backing off on timing to 8-9 degrees. Specs call for 10 BTDC at 800 RPMs. My problem is that my digital tach is not working. It works but I think the ground behind the dash is bad. If I have time, I hope to fix it during this trip. What ya think? Last edited by gchemist; 07-23-2008 at 11:13 AM. |
