I've been working with Megasquirt with timing and Fueling. The car has been responding well to the changes.
I had to take a trip to the foothills today and decided to take the 914 and really test the changes. Most of the driving I had been doing had been around town so I wasn't sure how the car would respond to a long freeway trip. while cruising up hwy 5 the cht's were 340.....I pulled up Tuner studios and leaned out the area around cruise a bit. Suprisingly the CHT's dropped about 5 * and were stable. I kept the setting there and was wondering how this would be when I started climbing hills, again I was suprised how good the head temps were. nothing over 370(which was for a very short time) on the long climbs. I don't have my 02 sensor connected yet so I can't say what the AFR is. At the end of the trip, I drove 176miles and it took 4.5 gallons to refill....39.1mpg......NICE!!! |

What mileage does a 1-7 get with Stock d.jet High 30' s. I'm guessing (IMG:style_emoticons/default/pray.gif) 34 was the best that I heard of. My 75 is a stock d-jet, and in about 1200 miles going up to Octeenerfest and back last year i had a whole trip average of just under 35mph. that included the driving in the mountains; / My a/f meter on the highway was reading about 13.7-14.2, . my speedometer is right on and odometer reads right at 1 mile according to milage markers on the highway. I now have a different MPS, car has been re-timed and tuned, it is running much better and cooler now so it will be interesting to see what my new numbers will be. I think they will be better wbut we will see. . - oh, also my transmission is not stock. i changed gear ratios of #4 and #5 so my RPMs run about 750 less at freeway speed than a stock motor. . |

What gears are you running in the 4th and 5th position? I effectively did the same thing with my tires. got 4%overdrive with 205/65/16's I have a project I'm thinking of that I may want to change the gear ratio's. |
