To anyone who is interested in the FJ cruiser's engine performance and how I was able through testing to improve gas mileage....
I purchased one of those Scangauge's that monitor mpg,horsepower,temperatures, etc... because I felt that I had horrible gas mileage I estimated to be around 14-15mpg.
After driving to work and back without changing my driving style I was averaging 14-16mpg. Being able to see the mpg change in realtime on the gauge I was able to adjust my driving to increase mpg and I was amazed at the differences acheived.
I have compiled a list of data that some may find interesting:
2007 FJ Cruiser 4x2 32" all-terrain tires w/3in lift, AT ****All data is taken from a flat surface @ 87-92F Intake air temp in high humidity(not sure of exact figure)... Shreveport, LA*****
0-25mph------14-21hp @ 0-6mpg!!!!!!!
25mph non-cruise --------17-19hp @ 28-35mpg
25mph cruise-------17-19hp @ 30- 35mpg
60mph non-cruise------ 40-52hp@ 28-33mpg
60mph cruise --------35-50hp@ 28-35mpg
70mph cruise --------47-74hp @ 21-26mpg
70mph non-cruise----47-74hp @ 19-25mpg @ 3.45GPH!!!!!
By using cruise every chance I get I was able on one 20 mile trip home from work by way of downtown interstate driving to highway and then through suburban stop and go traffic I acheived a 24.1mpg avg
Additional information that some may find amusing....
AT ENGINE IDLE: .33gph @ 5.5hp with a/c compressor on .45gph @ 7.5hp
On regular unleaded gas I acheived 243hp by flooring it from 0 mph at a stop sign.
Without cruise engaged.... coasting down hills and slight slopes on the interstate registered 60-90mpg @ 10-14hp.
And as figured disengaging the engine from the transmission produces 60-90mpg at speeds above 20mph.
Next I'm going to see how much of a difference it makes while drafting behind an 18 wheeler
Anyways... hope this was helpful to someone.
