That is basically what I meant in my earlier post - if no code is recieved by the engine ecu to disarm the immobilisation, the engine starts, and immediately cuts out.

I am not sure which wire you need to disconnect, but I have read of the need to disconnect one wire connection in conjunction with deleting the immobiliser - JohnDQ may know. If not, I am sure you will find the answer somewhere (if not by searching this forum, then have a search on some of the other Rover related forums.facebook groups).

To be honest, unless you really need to delete the immobiliser function for race/track use, it would have been simpler to get the code that the Pektron SCU and engine ECU share reprogrammed.

Hello Man in The car

Thank you for your time and all you bring us thanks to your experience

I have already sent the code scu to ecu with pscan without problems

My car starts and stalls but if I accelerate it remains start a little more but with a mixture of increasingly poor on the lambda probe and downing to 0.08volt, if I spray gasoline on the air filter, idle is better

So I have 2 options:
-Immobilizer: the ECU have now immobilize off, I can now start without the fobs but I must cut the link between the two because my memory SCU it probably die?
or
-Too much air or not enough fuel (the fuel presure is good,All companents are news)

I have find this information:

"Cut the pin 72 of the ECU. Cut the pin 23 (red and black ) and add it to Pin 2 (Black)"
(for Rover 25 NNN100743)

Can anyone confirm this for our pektron?
Does anyone have a diagram?

Hello,

I have try an other ECU+SCU but the trouble is still here.

I noticed after the start that the ignition advance goes from 5 to 30 ...

Do you think the VVC is blocked?
