Thread: Installing a TRS ECU with Nanocom...HELP!

So, essentially, I have to log the values from the original ECU, unplug, plug in, and then load those values into the replacement unit.

Are there any special processes I should know about? Is it just plug in, turn on ignition, start the nanocom, and what,..... I know that you can edit the injector codes, but the security key, not so sure on.

Anyhow, any advice from those who have gone before would be appreciated.

BTW, I did google this at the bottom of page, but no matter what I type, it just jumps to a Google sign in page???

Yes, I've done it, and sorry if my reply was a bit sketchy:

Everything you need is in the Td5 Engine module under settings.

Easiest way to do the injectors and throttle is to use the disk icon in the settings page to save them to sdcard (assuming you have an Evo).

When you get the new ECU you can load the saved settings back using the folder icon, then write to the ECU.

The security learn should be in the Td5 Engine module utility menu.

It's in the documentation for the Td5 Engine Diagnostics:

http://web.nanocom.it/download/TD5%2...20FUNCTION.pdf

HOW TO REPLACE THE ECU
1) Read the injectors codes directly from the injector or if it is possible from the old ECU by means of
the READ SETTING function (OT NOTE: You can use the disk icon on the SETTINGS page to save the settings to and throttle ways to file after you READ SETTINGS)
2) Verify if the accelerator type is 2 or 3 track
3) Install the new or used ECU
4) Read the injector codes from the ECU by means of the READ SETTING function, modify them, set
the accelerator type and write these new data with WRITE SETTING function. (OT NOTE: Load saved codes and throttle settings from file using the folder icon on the SETTINGS page, then WRITE SETTINGS)
5) Perform the SECURITY CODE LEARN to synchronize the alarm with the new ECU

When you save the settings you end up with a CSV file that looks like this:

Code:

NANOCOM - TD5ENG.APP - TD5 ENGINE settings file

param;value
Injector 1;NDGFE
Injector 2;LCGBE
Injector 3;NCLEE
Injector 4;LFGFE
Injector 5;NELEE
Accelerator;2 WAY

These settings are from when I changed from the MSB to NNN type ECU.

Because the settings files are basically a text file you can edit them in something like TextEdit (OSX) or NotePad (Win). You can even copy and paste the settings file contents above into a new document and use them as a basis for your own ECU, all you need to do is change the injector codes to match those installed in your engine. The main thing is to retain the param;value pairs and ensure that the file is saved as plain text and has a .csv extension. Once you are done you can copy to an sdcard and load in from SETTINGS page using the folder icon.

Yes, your right, it wasn't up to your usual encyclopaedic standards


Maybe we should change the good oil section to simply "Ask your Agony Aunty Paul...

Thanks so much for this. I just understood reading this that I am not looking for a security key, but simply syncing the BCU alarm codes with the new ECU. I get it now.

Also, for clarification, I see two options for the injectors. Save the file, and then write to the new ECU, or when you bring up the codes on screen, if you tap the individual box with a code in it, it opens an edit screen, with keyboard so you can re-type a new code. Either method would work?

Thanks again Paul
cheers

Either method will work. I prefer the "save to file, change ECU, load from file" because I'm lazy and it's far quicker and easier that manually typing codes in. That is what computers are for after all

The swap is done, and phoaw, what power! Works well, however, if anyone else has this particular upgrade, have you noticed a slower response from the cruise control when set? Mine now seems much slower to respond when the CC has to put the power on, say when we hit a rise.

Hi nick,

sorry to resurrect an old post but my cruise is doing exactly the same with a trs chipped msb ecu in a '99 auto, only thing is it was doing it before I upgraded it, have you found any solution to it? hows your fuel use going compared to stock?

Hey,

re the Cruise control, I noticed it because the factory setup was quite responsive to a hill, or particularly when i use cruise control to bring the car back to a set speed after slowing down. Previously the ecu would kick straight in and start accelerating the car immediately. Now, there is a lengthy pause before acceleration, and depending how far off target speed we are when the button is pushed, there may be a pause on the way up to target speed.

I just figured with the extra power they built in a lag to go easy on car, and conditions.

Re the fuel, I'm not so anal that I monitor it to the litre/km. But I have not noticed any significant difference.

cheers
Nick
