Before I order it, I'm concerned about the routing of the OBD cable through the firewall for my Right Hand Drive C43 Estate/Wagon. The JB4 instructions seem to be only for Left Hand Drive. Has anyone first hand experience installing the OBD wire for a RHD C43? Maybe BMS can advise?

Was looking at the JB4 website, and noticed a "boost by gear" feature. Maybe this will help Marcus to tweak his tuning during the launch phase? Just thinking aloud....

I do not think anyone did. But either way you can put it through the doorside gromet, no need to cut anything. Also the guys in the group can help you once you order one.

I'm not sure how they route RHD C43s personally but we ship a few per week and they are somehow routed. I presumed it was more or less the same.

Let's see some more 2019 logs and dragy times with the BCM so we can help dial it in!

Cool option! Our 2017 doesn't have that.

I doubt it's going to be as accurate as a high speed GPS based dragy, would be interesting to see results from both side by side!

How do you setup the BCM module after installing it? Does it auto tune and work in conjunction with all the maps on the JB4, or does it work off a specific map on the JB4?

There are default settings posted with the install directions. Once installed email me logs and I'll let you dial it in as there is a lot of tuning adjustability with it.

Must have gotten lost in the shuffle. Resend it or let me know your email address.

What kind of driving cycle does one have to perform for an ideal log. If you could describe a sequence of things to perform during and ideal log so that you can see everything, what would it be?

Sent again. Tried to PM you here, but you must have PMs turned off?

Do a 0-200kmph drag if possible. Or 0-160kmph ish also works well.

Other than WOT tuning, does JB4 tune for part throttle performance or is that irrelevant as anything in between is taken care of by default.

I should be able to contribute in about a months time. Meanwhile, I hope there are others who have installed the BCM already.
