Has anyone swapped a Bosch ECU using nanocom evolution. I ripped out the SAI on my truck and I am going to swap the ECU to get rid of the CEL and hopefully stop it from running rich (30L/100km Avg. right now vs. (19L/100km Avg. before).
I picked up a matching set BECM and ECU today for less than the price of the BECM anywhere else.
Marty I'm sorting the BECM first. Don't panic!
Any help would be appreciated.
ECU swap is simple...swap ECU, read immobilisation code from ECU , and program that in the BECM, you don't need to swap the BECM to swap ECU
I'm not swapping the BECM because of the ECU. I fried a circuit in my BECM last weekend and now my engine does not shut down with the key properly. I'll hook up my nanocom tomorrow and see if I can find the code you speak of. Thx.
Once you get the new BECM power board installed and it running properly, and are ready to do the ECU swap...
Remove old ECU,<br/>
Refit new ECU,<br/>
Before trying to start it, with the nanocom, key in Pos II, Go into P38 -> Motronic -> Motronic -> Settings. Arrow across to the 3rd page and at the bottom is 'Immobilisation Code' write this number down.<br/>
Then exit out back to the list of ECU's.<br/>
Turn ignition OFF (BECM responds best to diagnostics with ignition off)<br/>
Go into BECM -> Settings -> Alarm. You should get 'DIAGNOSTICS MODE' on the message centre. Don't worry if you don't just yet as long as you can still talk to the BECM!<br/>
Arrow across to the last page and you will see a box with 'Immobilisation Code' above it.<br/>
Tap the white box, and delete the original digits. Write in the digits you wrote down from the settings in the engine ECU.<br/>
Press Red X once,<br/>
Press 'Write Settings'<br/>
You'll get a confirmation.<br/>
Then exit out and 'DIAGNOSTICS MODE' should disappear from the dash.<br/>
Done.<br/>
Then put key back in ignition, and start her up!<br/>
Hope this helps..

I always wanted to know how to do that!

An now we do!
Every day's a school day :-)
As per usual, Marty is full of useful info! Thanks!
Had to do it a couple of times when testing other people's BECM's in my RR to make sure that they actually start the vehicle etc before sending it back... until I get the keys for my other P38's and I can use one of them as a test subject!!
Great Info, just found this site, Hello to everyone ! I'm into changing my engine ecu too, can't wait to try this out, hope I don't Brick my truck ! -> MartyUK : thanks, you seem to know your stuff, just need to find a nanocom now !

If it is electrickery, Marty is your man. If it is that pesky EAS, then Gilbert is my hero lol
I've heard somewhere that Marty also knows how to use a sledgehammer...
