Subliminally then. If you blink at the right rate you can see the name

Hi evo8, what's the bad reference ? Is it directly connected to the device or the local supplier ?

It is not related to the device - the device itself might be superb The problem is their tuning skills.

For you remap - if the tuner has done lot of D3 TDV6 - he might have some basic idea where to add/subtract parameters in order to achieve the desired results. But it is as I call "blind" tuning as he is assuming that the engine is in the same condition as the other cars he tuned before. I do not think that the 2mb of code in the ECU contains logs - it contains routines and maps for various processes, checks, fail-safes etc.

A good tuner needs to evaluate the mechanical condition of the engine, analyse the logs from sensors during full power pulls (road or dyno) and then start adjusting - then do the checks again, adjust and check again ..... I've seen tuned cars which run like hell - but died after couple of thousand km - high timing advance, poor fueling - detonation - and out. Without reading the sensors you as a driver usually do not know that something like this is happenning.

Bottom line - I would love to have the device - but I am not sure whom I can trust to make the remap for me I have not seen the code from the TDV6 ECU - and I doubt that I will be able to do it myself - as diesels are sligthly a different cup of tea

Is the device able to make logs of the sensors - ad the dowload into PC for analysis?

Bear in mind that if this device is POST ECM and therefore is still 'fooling' signals to and from ECM in the same way as the 'resistor in a box' method albeit in a more sophisticated way. As the dynamic data is not broadcast outside of the ECM there is no way this box can take account of it.... your choice

TFC...you've lost me with this last post.

As far as I can tell, the device is only used for reading and uploading data from the ECM via the OBDII port. It isn't used in any way to interpret and modify signals outisde of the ECM or fool anything - nothing to do with the resistor-in-a-box-eBay tuning method.

It seems to replicate the function of your equipment (on a basic level) in that it's capable of reading and writing ECM data. i.e. When the 'tuner' emails the remap back to the customer, they can upload it into the ECM using the device....

I think Mr Dastardly's original question to you was if you were able to remap an ECM dump (binary file) to TT standards if he e-mailed the original binary file to you.

I don't know of many (any ?) tuners who tune individual diesel cars on a dyno (generic tunes), most work from a fairly conservative base established with a test vehicle (done on a dyno).

Might sound a daft question ..but would it be a different remap for a manual and an auto ?

In a diesel the biggest problem would be high EGT's from overfueling or poor injector timing. Overfueling will typically result in more smoke, poor timing in loss of power (sometimes).
