02 Pontiac Sunfire Build.

[backpacker3]

Well not much is new but I've been working on my driving and so far I've been able to keep acceleration at or below 2500 rpm and at 50-55 mph I can keep the rpm to 1750 slightly more going up hill but still under 2000 rpm and acceleration from 40-55 mph is achievable with the tach needle nearly grazing 2000.

Hopefully I'll see good results from this tank but I'll find out once I fill up.

Finally I've received my arduino mega 2560 and I'm starting work on my OBDuino build hopefully all goes well with that!

I got 31 MPG on this tank! Not bad for all city driving IMO. Now my average is above 30 MPG.

I think you should see a big jump with the OBDuino

Nice job, especially with all city driving. Keep it coming up!

I had to get new front brakes this week end I just went with the o reilys brake best select one though so nothing too fancy. The pads came off pretty easy but then when I went to pull the rotors to have then turned the drivers side wouldn't come off. The end result of that was having to use half a can of PB blaster a map gas torch a 3 foot pry bar and another smaller pry bar while beating it with an 8 lb sledgehammer for about 5 minutes before it came off. So obviously I got new rotors as well, and of course the passenger side popped right off no problem.





I have a feeling this will really help my fuel economy as it seemed to coast much further now that the new brakes are on.

Brakes that hang up will definitely kill mileage. Nice find.

Had to put a new battery in today I couldn't take having to jump my car every morning so I bought a new one. It's a NAPA power 75 month.

A bad battery couldn't have been good for your mileage either.
