so on my tacoma it is very easy to run with no A/C or P/S because there are 3 seperate belts pone for A/C one for P/S and one for the alternator
so i did my ABA testing as follows:
tested at 53 mph with cruise control, truck warm, scan gauge reset for average mpg and measured once already up to speed
A:Belts off
33.4 mpg towards firehouse
39 mpg coming back
36.2 avg mpg
B:P/S belt on
34.5 mpg towards firehouse
39.5 mpg coming back
37 avg mpg
A:Belts off
34 mpg towards firehouse
41 mpg coming home
37.5 avg mpg
also there was a small wind causing the variation in to and from mpg but i thought I'd see what she did anyways..
definitely test could be improved on, faulty results because the avg kept going up as i tested however scan gauge read same temp the whole time so i know its warm enough.. anybody experience great results from this?
will leave both A/C and P/S belts off for a while and see how i like it and what mpg i can get i might have to increase my goal of 40 mpg to 50 mpg in my tacoma!!
I am in the middle of calibrating my scangauge II in between 1st and 2nd fill does this make any big difference on results?
