Thread: Remapping EU2 motors - a word of warning

Thanks for this brilliant post! I know my 10P appreciates it!

As I was poking around the my nanocom evo I noticed the following config/map:

sthle019 sttlp007

I thought my MSB had a standard tune, but when I started "googling" around found:

sthle022sttlp009
and
sthle022sttlp010

Overall, things seem to be running ok, maybe a touch rough at times. Any ideas as to the differences?

I've only just scratched the surface of the td5 electronics; as I'm trying to clear up some of it's mechanical issues before jumping head first. The depth and breadth of td5 knowledge on this forum is amazing!!

Cheers,
Mike

Forgot to add it's a 'fender 110, but you probably gathered that from the map info.

It sounds like you have the original non-remappable MSB ECU that was used with the 10P/EU2 motors.

The codes for the maps have two parts.

In your case the sttlp006, sttlp009, and sttlp010 identify the variant map. Variant maps contain the software that supports the hardware features of a particular ECU, so the sttlp009 is the variant map for NNN000120 running a Defender 90 fuel map, and the sttlp010 is the variant code for a NNN500020. In some cases the variant map is the same for both the Defender 110 and Manual Td5 Disco...

sthle019 and sthle022 are the identifiers of the fuel maps. The MSB and NNN fuel maps have significant differences and can't be interchanged.

So sthle022-sttlp009 and sthle022-sttlp010 are the same fuel mapping with paired with different variant maps to suit the NNN000120 and NNN500020 respectively.

I have a little software issue i hope someone can help me out with.

I have a huge amount of un-burnt diesel (white smoke) being blown out the exhaust when idling with the NNN ecu fitted. Admittedly I also have very low comp on No1 cylinder so a bit of white smoke is to be expected. So to rule out a SW problem I fitted the original MSB ecu to check the injector codes and a few other things and started her up and the smoke is now only noticeable when No1 fires. I am running the correct default fuel map on the NNN ecu for my engine. I don't get whats wrong. Anyone have any ideas?

MSB ECU running -

Config. tune ID: sutdp008
Fuel tune ID: suhde024

NNN500030 ECU that I flashed with -
Config. tune ID: sutdp014
Fuel tune ID: suhde036

double up

Here is some video

this was just the change of the ECU

NNN Ecu

MBS Ecu

For anyone wanting to do this to 99/2000 plate car you might find 1 wire is missing from the pedal. You need to add a wire from PIN C on the pedal plug to pin 20 on the ECU (Black Plug) and also the APP wire.

So paul, (aka OffTrack)

I have a very similar td5 d2 to yours, (even same colour I think!) but have a trs remapped msb ecu, after your experience doing yours, do you think you actually gained anything from converting over to a nnn and the 4 wire aap,

as I already have a remapped one would I be likely to see any improvement, ie power, fuel economy, driveability etc, ( I know I know.. how long is a piece of string)

also does anyone have any experience how a stock d2a compares to a d2 in performance,
I always thought they were identical,... but maybe not
otherwise lr probably wouldn't have made the updates , or maybe this was primarily for eu3 specs?

The main reason for the 4 wire AAP was to give the ability to utilise the EU3 maps which apparently have a bit more tweakability than the EU2 maps - they do at least have more tables for the tuner to work with. I'm still not entirely convinced it was really worth the effort.

Swapping to an NNN ecu gives you flexibility to load maps more than anything else. The end result in terms of economy, power, drivability will result from the map that you load rather than the hardware itself. If you were chasing economy as the primary goal a tuner should be able to optimise the mapping to suit, likewise if you wanted major power increases a tuner should be able to sell you something that suits your needs.

So it really boils down to whether you are sufficiently unhappy with your TRS ECU to justify the cost of an NNN ECU and a new remap.
