New Datalog!!!

Just wondered what people think of this log.

Also did this log as a test for the intercoolers but it would be good to see what people think of the map on the car as well!!!

Looks like you soaked the coolers a little with a few runs, and then did a run to about 270 km/h? Your IATs are pretty impressive. Never exceeded 40C. How many runs did you do prior to logging to soak them? Your AFR looks lean. What does FVD consider the target AFR for this engine?

- edit - my bad - did not look at entire log on excel. If anything, looks a touch rich at max load at the end of the run. AFRs in the 14s-15s were not under load.

Your welcome.

I did about 3 high speed runs but 2 of them were upto about 150mph and the 3rd was up to 170mph.

It was a little busy today so didn't want to over do it.

Looks solid and safe, turning a bit rich in 5th gear. IATs are good but boost is "only" 1.2 bar for the most part. I looked at a log I did on a 17C day at 1.2 bar and the IATs were almost identical at equal times/speeds under load. See what happens at 1.4-1.5 bar and good gas! They should shine there.

Edit: Looks like there are sporadic attempts to deliver 1.4 bar below 5000rpm but its tapering to 1.2 as soon as you get past the initial hit. Would check with FVD to see if that's intentional.

What type of fuel are you using? Looks like some timing being pulled at the end with high load. You should be able to achieve full boost 1.55 bar with your set-up even on 93 (r+m)/2 octane. Better check with FVD.
