Rtek data

I use my car for HPDE track events and as an instructor I do between 10-15 events per year. A typical event has 3-4 30 min sessions per day of open track driving. Most events are two days although three is not uncommon. I drive my car to the track and tow a small tire trailer with 5 race tires and spare parts. Most tracks are between 75 and 300 miles one way. With all this in mind it's important that the car be reliable and not blow up. My experences are with only 10 psi which is so low it may not be relevelant to the big boosters on the board. I dyno somewhere close to 230 RW HP and that's plenty for how I use the car. I attached a chart of rpm vs boost with the AFR listed a lambda (I perfer to think of "percent richness" so lamda of 0.8 is 20 percent rich comapared to 14.7-1). The numbers in the parathesis below the lamda value is the number of times that the particular cell l was recorded during a log. The color shows the average values for the various lamdas. If you do the math on the chart you can see that I'm either on the gas hard or off the gas braking for a turn. Of the time I'm on the gas fully 37% of the time I am from 3500-7000 accelerating out of a turn. This is where the fuel map shines- "rich torque?" My map gives me a full rich cushion in that range. I average about 7.5 MPG in that mode and 17.5 on the road going to the track. So far I am pleased with the performance of the car. I will add more data but this is just a start to indicate that at least for low boost levels Rtek 2 works very well.

Are you running at the "default" settings or have you changed anything? Also, I could not really see anything on your attachment (screen shot is too small).
