Givin the ecu more power
I havent started to push my td5 to the outer limit. But in its current tune i cannot run higher than 4000rpm, my engine completely shuts off, and my injector run time is pretty maxed out.

I am runnin a nnn500250

Am i able to support the ecu with a 1 farad capacitor so it has more power on tap? And can run the injectors longer?

Should i switch to the other ecu? Like the 500120?

Wouldnt work for me, i barely get to 130kph or 82mph...

That works at 88mph...

Honestly you're going to struggle to go faster, at 60+MPH Aero drag kicks in and squeezing much more out of it is problematic.

The Focus RS is limited to 155 by aero and thats pretty slick

You have to consider you're driving a 3 tonne brick wall... besides you have to be a nutter to go 60+, a lot of the commercials are locked at 55... I'm on IG: https://www.instagram.com/osloblue42/

Nut or not, my friends here were caught doin 150kph with a puma 2.2.

I am gonna keep it simple, swap out my fuel pump and fuel filter. If there is a sudden surge of power then i found my problem. If not then crank sensor, if still not then a new engine harness.

I don't think ECU power will ever be your issue, plenty of trucks on here over the years running 150-200hp without needing to find ways to provide more power to the ECU.

Besides that, although a solution most loved by the lower end of the ICE world, slapping a "1 farad" capacitor in won't solve an issue in 12v supply even if there was one. Do you have measurable voltage drop at the supply pins to the ECU?

I think you need to get the truck running properly first. Mine is completely stock and will do 80 on the flat fairly happily.

Yeah I’ve pushed 85 at ~3500 rpm (by accident) and still felt it had more to give (probably top out at 95). I’ve only got a straight through pipe and k&n filter, and a RAI with that too.

Nad, the ECU power outage isn’t limp mode is it? After a certain boost pressure it will cut out as it realises “oh sh*t I’m going improbably fast”.

Also how often do you change your filters?

In all honesty I don’t think your going to squeeze much out of her given the atmospheric conditions of your locale, you could probably buy a 15p engine, rebore, blueprint and remap it and you might be able to squeeze a bit more out of it.

Honestly I’m surprised someone hasn’t made an investment and invested in upgrading td5 parts like performance injectors and the like. I'm on IG: https://www.instagram.com/osloblue42/

All TD5 ECUs has nearly the same design, the parts responsible for power injectors are the same. So there is not possible to gain something wit different ECU.
Main difference between MSB ECUs and NNN000120 or NNN000130 is change from EPROM memory to flash memory, so it is rewritable in ECU.
Difference between NNN000120 or NNN00130 and NNN500020, NNN5000030 or NNN500250 is in switch chips used to control relays (AC fan relay, AC clutch relay ...) and another outputs - the NNN5xxxxx ECUs has newer chips with improved cooling.
MSB ECUs has the same switch chis as NNN0xxxxx chips.
To check the proper function of you ECU you can simply measure voltage across the two big capacitors inside - it should not drop significantly during full power test of engine. Adding bigger capacitors it not the best idea - you still need the energy to charge them. Bigger capacitor means higher current.
Did you measured fuel pressure? I have experienced power drop, when the fuel pump in tank was partly death, probably working only one stage. The drop was on noticed on highway - maximum speed changed from 160 to 140kmh (Discovery 2 with manual gearbox). "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo Smile

Surely the reason why nobody has “invested” in performance injectors etc is that the Defender is a truck, not a Ferrari.
Although l guess it would be fun to see the faces on car drivers, l can’t see why anybody would want to do over 100mph in a Defender.
There’s room for more power on acceleration or when towing as the standard power is fairly conservative, but l fail to see the point of screaming the head off the engine trying to get to BMW speeds.

Yes, Defender or Discovery with TD5 is not a Ferrari, but our Discovery 2 used for trips is a bit heavy when fully loaded, like 3200kg. And just imagine a slow truck in front of you, running 20kmh uphill, with standard power, I cannot even start thinking of overtaking, so I need more power, but for short time. The same, cruising uphill. Travelling through Bosnia and Albania, even on main roads, average speed is much bellow 50kmh, and just to pass the country through, on the way home, it is like 2 days, so waiting behind a truck is not the best idea.
I don´t need to cruise over 110kmh on highway for long time, but I need it at least for short time, for overtaking.
And add to this need for more power in low RPM when offroad, with heavy car used for trips. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo Smile

TD5inside havnt maxed out the injectors yet. As they where developing some wider bore ones but stopped as the standard ones still have more to give.

I suspect your issues are because you strapped on everything you can think of without knowing how they will all work together.

.my 110 will hit 100mph easily without screaming or it even being hard, it could probably go faster but 3 ton of landy... Instagram @defender_ventures

It’s not so much P O W E R so much as lightening moving parts to make their movements more efficient so less fuel used for the same output. I'm on IG: https://www.instagram.com/osloblue42/

I thought the 110 was two tons not three?

I agree the standard TD5 is left wanting particularly on hills, so a bit more power is welcome. I’d like to fit an overdrive for motorway use. I tried a 90 with a Disco transfer box but l found reverse gear too high, it’s a good option though as it is fairly cheap to do.

I keep considering the Disco transfer box, but I think I'd end up needing to drop into low box too often when towing...
