Not sure what you are asking re: numbers for Duty Bias??

100% stock with the exception of Michelin PS4S tires instead of the crappy run-flats it came on.
full tank of 94 octane on map 3.

Then I assume you're at the default numbers.

Great times! I'm glad to see that you went with the BCM. Your car is definitely an 11's car, on pump gas, with just a JB4. I think that puts to rest any thoughts the 2020's can't make equivalent power to the PFLs. Having said that, 12,7 @76mph? Yeah, I'd say you definitely let off. You need to find a place where you can stay in it the whole run.

It definitely rocks the 0-60! Times are quicker than my GT3 Touring.. 4.06 best, but my manual shifting needs practice!

1/4 mile runs feel flat on the top end, not pulling about 3/4 way through which is why I had lifted.

This time was slightly better, still let off as seen by the 86mph trap spd...... Will try again and this time hold the damn throttle!! LOL

The 43's do run out of pull up top, because of the size of the turbos, which is why the mile per hour is normally lower than you would expect for the times that some guys are running. As for shifting, the best times that I've heard of guys running were always in auto w/ the suspension set to comfort vs. sport, to help weight transfer off the line. While you're in practice mode, give both ways a shot. Presuming everything is running well, I would think you should be running 115+ mph

I'm not sure I understand. Are you saying that comfort suspension is better for straight line launches because there is more flex?

Wow, that's very nice. I thought you were running e85. The latest gen c43s seem to be very impressive in terms of acceleration.

Yes - allows the weight to transfer a bit more aggressively to the rear on a dig

I understand this in theory, but does the suspension setting actually do enough for the result of this to be measurable? I mainly have my rear tires about 2psi under my front for this reason, but I didn't think the suspension stiffness from Comfort to Sport+ would actually help.

It does make a difference. It has been proven by several of the fastest cars on the board. In most cases, a one tenth difference in 60 ft. time is equal to 2 tenths in your quarter mile time, so even small benefits count. Consider, that means that .05 second difference in the first 4 car lengths translates to one tenth off of your quarter mile time. In Sport+, the suspension is stiffer, better for handling, but worse for a launch from a dead stop.

Very interesting. I will have to try this.

Had it set on S+ & sport + suspension. Will try comfort setting next time also! I did have traction turned off and didn't feel any wheel spin.
I also brake boosted the launch to 2000 RPM.

I'm interested in ordering a JB4 but I don't plan on installing a BCM. At what map does the BCM become necessary?

I believe all maps require BCM if you have a facelift model.

That is exactly what BMS told me for my FL C43, so I added it when I ordered the Dragy.
BCM is not required for pre-FL C43's.

Contrary to popular belief the BCM remains optional even for facelift models. It's only required if you're expecting pre-facelift like performance metrics.

When install (takes 30 seconds) it's active and provides benefit with all maps.

Lots of options to make sexy! Front lip and trunk spoiler. Check out this C43 we did.
