That is the next step after I get the codes cleared and running properly. MPGuino to me is a waste of money UNTIL the car is repaired and running properly. Then it becomes a very useful tool. I look forward to that step. However, I have done searches on how to hook up the MPGuino on here and cannot get any real answers. I posted asking and the response is only "that it should work". I am surprised at the lack of info in that regard. I know there are other CRX HFs on here. One thing I have learned in the last week driving the BMW....the factory fuel mileage gauge helps tremendously with throttle modulation. I now use the fuel mileage gauge to watch going up and down hills. I try to keep the fuel mileage at a certain level going up and down hills. I have noticed a huge improvement. I have got the most miles out of a half tank ever this week using this technique. I used to coast down hills and power up hill. Then read somewhere on here that you should use the down hill to accelerate and thus gain more momentum for the up hill. Of course full throttle down hill does not do you any good. But, I try to keep the indicator above 30mpg down hill while accelerating and then keep it above 30mpg going up the hill letting my speed decrease to keep the MPG up. I would have never learned this without the BMW fuel mileage gauge. Also, I guess on the fuel gauge not as a sure thing MPG rating. I just use it to get an idea. When I first started driving the CRX with the improper ECU I was getting 100-125 miles at the half tank reading. I only use actual gallons on fill up and miles (now corrected due to tire size) to figure actual mileage.
