Thread: Remapping EU2 motors - a word of warning

ImageUploadedByTapatalk1371769095.365703.jpgDoes this help?

Many thanks, that'i it :-)

anyone got a heads on the pin number on the old aap sensor and which pin number it corresponds to on the new aap sensor? and which pin on the new sensor the 4th wire attaches to? well, i can't actually see pin numbers on mine but a description would go a long way too.

wasn't going to get this done till went home in few weeks but unfortunately have had a rush of enthusiasm.

my RAVE is at home and after a few web searches...........well, i give up so need to ask the question.

The 4 pin connector is marked with letters rather than numbers, 3 wire AAP pin numbers in brackets:

ECU RED pin 30 -> Pink/Black -> Pin A (Pin 1)
ECU RED pin 31 Green/Blue -> Pin B (Extra 4-wire AAP connection)
ECU RED pin 8 -> Pink/Purple -> Pin C (Pin 3)
ECU RED pin 10 -> White/Yellow -> Pin D (Pin 2)

Thank you Offtrack for a highly informative thread.

I have a 2000 D2 TD5 Auto (owned from new) & 5 years ago had an upgrade to a flashable ECU & had it flashed by a Sunny Coast indy.

I have a Hawkeye & prior to the upgrade had no faults - After the upgrade, Hawkeye showed the 2 coolant faults & the transmission fault as outlined in your posts. It also shows my AAP between 115 - 117 (I live a sea level).
In spite of that I was pretty happy with the performance, both improved power & fuel consumption. Improved fuel consumption was a bit surprising given the increased AAP reading would cause overfuelling.

After a bit of trial & error, I decided that fuel consumption & power were even better if I simply unplugged the AAP sensor causing it to use the default of 100. It has been unplugged ever since.

Thanks to your posts, I now know all the technical reasons of, why?.


Adios.

thanks paul.

even though my vehicle is a defender, the current 3 wire sensor i can match the wire colours you mention so ok with that one though can't see any identification at all.

whilst i mentioned earlier there were no pin numbers on the 4 wire either the new aap sensor does have the writing 2314 as per attached photo which i had assumed was some further identification for a part number etc. (there are 4 pins on it though in the photo you'd swear there only 3!) in my mind i was expecting them to be in sequence, but are these the actual pin numbers?

do you recall where you sourced the connector for the ecu end of the new 4th wire or a description?

thanks,
brett.

Adios.

Thanks mate.

I might try this until I can afford a new map from TD5inside

If you do unplug the AAP make sure you secure it with a cable tie or similar - You don't want it dropping down near a pulley or belt!

BTW - I have the same VIN as you, SALLTGM93YA2xxxxx. Mine is a 2000 model with the CDL gizzards.


Adios.
