Hey guys, update on my 1JZ (Toyota 2.5L turbo) powered Datsun. These are my results after my aero modifications and fuel/ign tuning.
These numbers are rough, speedo was in miles, and reading 7% slow according to needle position vs gps (hopefully the trip counter is pretty accurate to the needle) thanks to differential and transmission changes. The fuel cell was filled up to the "that looks about as full as it was before" point.
After crunching the numbers, 33.5 MPG, 14.1km per liter. Im shocked, I may not have filed up quite to the same level ( I put in 30L from gas cans I filled at pump)
I hope to keep improving this number with tuning, I've since pulled the A/F from 15.3:1 to 15.6:1 and ive noticed my injection times coming down noticeably. All driving was 90km/h and under, no P&G or anything, fair amount of steady crusing, few instances of positive atmosphere too
This is better than my DD, more excuses to drive the 300+HP classic
