Dyno - Mileage

In Daytona I took the car to Redline Performance for extra tuning of the engine control computer. Although it ran well and made lots of power, fuel economy was very low at about 14/16 mpg when driving gently on the street.

We ran the car on Redline's Dyno Mite Chassis dyno, monitored air/fuel ratios (AFR) using the dyno's Wide Band Oxygen (WBO2) sensor on one bank and my Innovate LC1 WBO2 on the other. This allowed us to safely lean out the AFR at low load and RPM for better economy (and improved pollution control).  We couldn't resist a couple of runs and minor changes at higher RPM and full throttle. Minor changes also added about 15 HP at some points in the power curve and around 10 HP at high revs and peak power.  When compared to the base map that was developed on a SuperFlow engine dyno a couple of years ago, power, mileage and driveability are all improved. :)  It was a productive half day.

Fuel economy improved to around 21 MPG in the several hundred miles driven since the "Tune Up". :)

In total we drove Uggs 1323 miles in warm sunny Florida during the trip.

Kirkey Seats and Mileage

At year end 2014 I had put about 6000 miles on Uggs' MOTEC digital dash/data logger.

The picture shows about 650 RPM on the graph, 199*F coolant temp, 194*F oil temp, the big 0 is the current gear selected and is calculated by RPM vs forward speed, the car was stopped therefore no valid calculation could be made, i.e. if the car was going 60 MPH and the revs were 2000 it would display 5th gear, 29 PSI oil pressure, 0 MPH calculated via its GPS satellite sensors, 7.6 gallons of fuel remaining and 6035 total miles logged. The total miles displayed is around 5 or 600 miles low because I did not have the MOTEC installed until after the car had been running for a short while.

 

Santa brought Denise and I new Kirkey Intermediate Road Race Seats for Christmas.  As seems to be normal it took me longer than I had planned to get these properly installed prior to our departure for our 3 week trip to the Daytona Beach Florida area. It was a scramble but it got done. Pix follow.

More info will follow in the next couple of days regarding the dyno tuning and drag race experiences. Thanks for following this blog.

 

Long overdue update

Just returned from 3 weeks in Daytona Beach Florida with the car. Prior to the trip we installed new Kirkey seats and changed front brake pads.
During the trip we:
1. installed my Innovate LC1 Wide Band Oxygen (WBO2) sensor and connected it to my HP Tuners interface so that I can monitor, display and log Air/Fuel ratios for proper tuning of the fuel injection system
2. ran the car on a chassis dyno and modified the engine control computer's calibration to improve power slightly, low speed drivability and fuel mileage (significantly)
3. ran the car on Orlando Speed World's 1/4 mile drag strip
4. enjoyed about 1400 miles of warm and mostly sunny Florida roads
5. cruised Daytona's Bike Week among the interesting custom bike show
6. attended New Smyrna Beach's Collector Car Show that is held monthly
Now that the rush is done, I will try to do a better job of posting regular updates
