Turned the fuel screw in a bit less than a quarter of a turn. Noticeable improvement in power / ability to hold speed in the 90 to 120 area. EGTs up to 630 on a long rise so don’t seem to have over done it. Will monitor it over the next week , will prob need to adjust smoke screw.
Ours was turned a quarter of a turn. D1 300Tdi auto. Otherwise standard.
Cruised happily at 100 kmh, or 90 - 95 when towing.
Can you give me an idea of what your egt's are doing - lets say you are heading up that long rise on the Hume as you get close to Glenrowan from the south on the Hume hwy, it is 30 degrees ambient, you have a camping load on, and you hit the bottom of the rise at 110. You attempt to hold 110 all the way up - what would you expect your egts to do? Could you hold 110?
I would like to know also. Everything under the hood is standard issue, it has not been tweaked at all, so there are no extra guages, I have no egt info. The only thing I have added is a low coolant alarm.
I dont remember speed at Glenrowan, so cant be that bad. Next time I head up that way with the disco I will take note. For long steep hills some days are better than others, 30+C saps some power for sure, on hot days it wants to be running light and given some sympathy up the hills otherwise it starts to get hot. Note to self: a new rad core for the summer.
What kind of egts, speed are you getting?
I think I could hold 110, just. EGTs would be over 650 ( and may max out ie 700+ so that I would back off) at the top under those conditions.
It is well and good to set the fueling so that it doesnt go too quickly to 700 but the real setting for sustainability is worked out over a hot summer with a mix of long haul highway and off roading in the heat.
I think mine is close to max but will monitor as the days get hotter.
Smart moves.
In the tweaked defender I find egt is easily brought under control with right foot, even on very hot days. My egt alarm goes off at 690C, and I only need to back off the accelerator a fraction to hold it there. If I were to push on I could shoot it well over 700 im sure.
Offroad I have never come close to tripping the egt alarm. Mostly low range trundle, never racing.
just like to point out to the pump tweakers that if your pump has been re-conditioned by a reputable IP place that knows those Bosch pumps, it is likely to have already been tweaked off the shelf. i wasn't aware of this until a perth landrover specific mechanic told me this. so if you have it, check your car history to see if IP has been recond and if so see who did it. there's only a small handful of injection specialists in perth that the small handful of landrover specialists take the pumps to and all lof them have pre-set IP up-tune settings, in which case, be careful how much you play with it as you may get very close to top EGT. do not play with the pump unless you have EGT gauge.
obviously if you install a better IC or VNT etc. then you have more room to tweak pump but the above is FYI.
You guys are all lightweights i had family and car loaded up away for 5 days camping on the way home so we would have been slightly lighter i was 3020kgs on the weighbridge. Last time I weighed myself coming back from a solo 7 day trip same weighbridge i was 2580kgs i have added a few things since then plus minus family and all associated crap that comes with them.
I can cruise at 100kph with family but the roof rack is stacked so having to punch such a large hole causes egt boost and water temp to be higher than i like. So i was mostly around 90-95kph mark depending on headwind. Solo i can sit on 110 easy and be comfortable with egt water and boost readings.
Note i have 265/75r16s with 3.54 and 1.2 transfer. Sit on maybe 2200ish at 100kph hard to tell with speedo being out
