Where did you mount the nanocom?
Hi All,
While traveling to the Fraser Island and back I noticed that doing around 100km/h with camper trailer a little easier with aircon 'ON'. The outside temperature was about 30-34 C, all windows and flaps were closed. According to Nanocom coolant temp 89.8-90.2 C, turbo pressure no more than 0.9. Overtaking trucks on long uphills was like a song - just a little more right foot and from 80km/h to 100km/h in a few seconds.
Still don't know what it was. To check that aircon makes a difference I tried to do the similar exercise without it, and once it switched off, after about a half a minute I was loosing that sweet uphill performance. It wasn't bad, just normal what I used to and expect from such load.
I'd say it is another nondocumented feature of the Tombraider's remap
Thanks,
Ruslan

2005 Defender 110
It was mounted only for trip next to UHF radio on top of the screen panel. I've started building PC computer with 10" touch screen a week earlier before the trip, so we have used GPS/OziExp/Destinator all the way.Originally Posted by Captain_Rightfoot
After a bit of research some ideas came up:
- Closed windows/flaps help to reduce air resistance on high speed (well known fact)
- Aircon electric fan helps to reduce intercooler temperature (???), so a bigger intercooler would be better, no words!
- Aircon compressor mounting points loose or/and to check belt's tension
Can someone think something else, please?

Looked at your avatar, you've blocked the airflow with driving lights, like me.
I think you're close to the money in saying the a/c fan is on, forcing a better airflow across the intercooler. But I can't say I've noticed an improvement.
FWIW I think your TD5 is working hard at 100 kph, on those Nanocom readings. Mine sits spot on 88 degrees until it hits a long hill, then it can rise temporarily to 98 degrees.
And at a steady 100 kph my boost varies from .6 to .9. Obviously changes according to headwinds, crosswinds, gradient. But never a constant .9 or so. Actually it can go up to 1.05, as the cruise control attempts to hold 100 kph up a hill.
This is at a genuine 100 kph too, not a Defender speedo's 100. I've had a truespeed fitted, and its spot on with the GPS.
Watching the Nanocom can be quite entertaining!

Thanks for response, Max. The driving lights so good, I better live with them and drive slowly.Looked at your avatar, you've blocked the airflow with driving lights, like me.

You right, 100km/h on Defender is not real 100. To be correct I was doing 95-105 according to GPS, dropping to 70-80 before overtaking and accelerating up to 115km/h while overtaking. Only once I noticed boost went to 1.04 for second at 3010rpm when I was on 3rd (overtaking run-up uphill), and on 5th it never gone over 0.9 (0.3-0.9). So looks like it normal compare to your.
Forgot to tell, the fuel consumption was surprisingly good. Lowest is 11.3L/100km towing camper trailer at about 100km/h, got it from 3 tanks one after other.
Cheers,
Ruslan
