Right boys chap off here came over with his 2001 p38 hooked it up and bingo reads the lot have to say bit miffed as he got more info off his Bosch than I did off my Gems but goes to show that the Lynx will work on any vehicle of that type .
Has Mr Gorsky been over with the Nano yet?
The code on the GEMS is set. When the BECM is first connected up (at the factory) you put it learn mode and cycle the ignition, this sets the GEMS code in the BECM.
When it looses sync, you put the BECM back in learn mode and it relearns the GEMS code and away you go again....
I've read that if you reprogram the GEMS code to FFFF and the make your BECM learn this code, the sync issue is cured. This is because when the BECM forgets it's code it defaults to FFFF.
I'd like to try it, but you need Testbook (or perhaps Lynx) to program the GEMS ECU.
The times my BECM has gone out of synch it certainly wasn't at FFFF.
According to an article on RR.net, the BECM only forgets binary zeros, or at least, if it can't read the proper digit for whatever reason it defaults that bit to a binary one.
Therefore, making the code FFFF means it's all binary ones and if it does have trouble reading to proper code it'll default to a binary one so it should't ever loose sync. LR did an official update, but it was only ever offered to USA customers, so perhaps it doesn't work on our UK cars, however I'd like to try it!
I believe all US cars have a generic 1515 as the EKA code.
Is the EKA the same as the BECM to Engine ECU immobilisation code? I didn't think it was.
No it's not, went off on a tangent there sorry.
Slipping up one to frame didnt think you were ever wrong
Was just making a statement about EKA code in the states they are all the same. Just wondering if all the engine ECU codes are the same. But for some reason did not add that bit.
