L200 Remaps - for better power, performance and economy

Hi. Having spotted a few topics including questions concerning remapping, I have asked Admin for permission to post this topic concerning our services and what you can get from a remap for your pride and joy.

The L200 can be remapped for significant improvements in horsepower, torque and economy. The torque improvements in particular lead to a much better performing vehicle that is also nicer to drive. Flexibility and pulling power greatly improve, leading to less gear changing, and faster responsiveness provides much greater safety margins when pulling out of junctions or overtaking. We have remapped a lot of L200s now (and other Mitsubishis with the same engine) and every customer has been delighted with the results we achieve.

Diesels get the best all-round improvements, though the petrol engine still benefits to a worthwhile degree from the improved low-rev power and responsiveness too.

The gains are as follows:

Power : Diesels

L200 (III) 2.5 TD (ECU: Melco MH72xx) = 26 bhp, torque 19%

L200 (IV) 2.5 16v DI-D (ECU: Denso RHF4) = 31 bhp – 37 bhp, torque 16% - 21%

L200 (IV) 3.2 16v DI-D (ECU: Denso RHF4) = 32 bhp, torque 20%

Power : Petrol

L200 (III) 3.5 V6 (ECU: Mitsubishi E6T47xxx) = Approx 5% bhp and torque

MPG - Diesel

MPG improvements (only applicable to diesels) vary according to driving style and road conditions, but MPG improvements are normally in the range of 8% to 12% and, in some cases, can be as high as 20% though gains at that level should be counted as a bonus.

There are three ways we can remap your L200.

1. You can bring the vehicle to us (Mk III only) = £300
2. We can come to you (Mk III only) – up to 30 miles from Caterham = £350
3. You can send us your ECU (Mk III and Mk IV) = £225

If you choose to send us your ECU you’ll find it tucked up in the passenger footwell, to the left of where your feet go rather than under the glovebox. It’s easy enough to remove on the Mk III as there are less wiring harnesses in the way of the ECU. I hate getting the ECU out on a Mk IV so I’ll leave that to you! A competent mechanic can get it out easily enough but agility getting under that footwell isn’t my strong point! We normally turn a remap around the same day we receive it so long as it arrives reasonably early in the day so, if you send us your ECU on a Monday for next morning delivery, we’d hope to get it back to you by the Wednesday.

Please feel free to call for advice. Advice is free, honest and clear, so please don’t hesitate to pick up the phone. You can also e-mail us of course. We also remap most other vehicles from family saloons, to exotic sports cars (Aston Matin Vantage 4.2 the day I wrote this) and vans or even HGVs.

I should also mention that some vehicles are not remappable and, acknowledging that owners of vehicles that are under warranty may not want a remap, we also sell a very advanced plug-in tuning module (tuning box) that genuinely provides outstanding results. Our tuning module is custom mapped for each engine type, has 9 settings (with clear instructions) for varying mixes of power, torque and economy, and unlike most tuning modules has the option of being connected to the turbo to further improve performance for those wanting to squeeze out the last few percent of improvements from their engine. Please call for details for your vehicle if you're interested.

Many thanks

Is the ECU truck specific or can I buy a used one end send it to you for remapping and put it in my truck when I get it?

Oooo oooo found it !!! I will post some more later when home!

I have a few questions Paul .....

1. Mine is a 52 plate fbw .... So what mark is that ?
2. How is this tested if you don't have the vehicle? My understanding of re maps (iv had a few on my car) is that every vehicle and engine is different, so if you map the ECU without the vehicle to 'x' peramiters it would perform differently in my vehicle to the next mans.

All the oem mitsubishi tuning boxes (and all the aftermarket ones come to that) are only a generic re-map anyway though.
Although you could go on the RR and have yours mapped exactly to spec it will depend on how your car is set up, what components you are using and even the weather on the day of the map.
If you change the type of diesel you use after then the 'custom' map won't be valid any longer. The more you change/mess about with the truck the further from the expensive custom re-map you will be and the closer to being better off having just had the 'generic' version at lower cost.


Couple of questions I do have though,
If the re-map adds 26bhp to a euro3 L200,
Is this to the 'standard' or animal version?
The standard truck is 114bhp, the animal is 134bhp. so when you map the animal does it come out at 170bhp?

Same with the E4 L200, 2 power outputs available from the factory, does the ecu map you offer add 31-37 bhp to both of them?

Question - I`ve just changed the boost to allow for the snorkel, how does an electronic chip take account of mechanical setup (or poor adjustment) like turbo adjustment screws

Ideally Geoff, fuel will be adjusted by software and boost should be adjusted to compensate for extra fuel so that it doesn't smoke like a trooper lol, and to keep the boost pressure at safe levels.

Twedl .... This is what I was thinking ...... I'd happily pay for a bespoke map to my vehicle but not too keen to put a generic map into it.

Paul .... Do you have a RR at your disposal ?

I`m finding the changing moods of my truck interesting as it realises when the hydro cell is or isn`t working - fascinating that when its been off for two tanks , the first tank after turn off still does more mpg than before, then returns to normal crap again, only to go straight back up when the cell is started again, then drops off to half that initial level

so I haven`t got a thinking truck Lez?

thinking`s over-rated wee bro

If anybody does want to go for this I have a ecu here, £50. You could send it off, get it mapped while still driving yours around.
Then, either sell yours on to the next guy in line to do the same with or keep it and sell your 're-mapped' ecu when you re-fit your original when you sell the truck.

I thought the FBW's had adaptive ECU's???

so, if the hydro cleans the gas ports through water injection/superheated steam, as advertised, would that account for the changing fuel / mpg? and if so why would it fall back when theres no hydro?

I didn't realise that HHO cleans the engine too. But, if it does could it be that the cleaner engine runs better until, with no hydro, it cokes up again and mpg reduces.

cant see how without the vehicle and a dyno how you can do anything but mild tweeks to an ecu, 2 ecu`s, one driver runs normal diesel, and his only mod is the removal of the cat, driver two runs twin tanked, has dumped both the cat and egr , runs with an apollo, assuming no faults both ecu`s std maps should look very similar, however the second one breaths better and is initially running on one fuel before changing to another fuel, add to the mix one guy mainly drives around the lowland fens the other guy say lives in the highlands

funny enough i seem to remember on the oc we had a member ( sadly missing now) called phantom tech, im sure he reported a higher fail rate of engines that used the tuning chip which is just a basic remap

There will always be a higher fail rate on tuned engines.
I am sure that the reason for this is the driver though.
The sort of person that wants more power in the first place is going to be prepared to use it.
Give my grandad a truck mapped up at 300bhp and he will still make it last forever just by never revving over 2.5k.
Give my mate a 114bhp truck and he will kill it in a week by towing a 3.5t digger around and using low range with 4500rpm on the hills.

Even a V8 tuned up has less life expectancy than a non tuned version of the same engine.
