i have a 1998 206 XSi and as you probably seen in the project thread its being converted to a rally car. Question is can the Engine ECU still operate without the BSI?

The BSi doesn't take up a lot of room so it might be better off just leaving it. But you can unlock the ECU, start the engine, whilst its running unplug the ECU [this will unlock it], then cut wires to pins 22 and 48 as these go to the immobilser. Quick look at the wiring diagram only shows the wires for the immobliser going to the BSI

The reason behind wanting to remove the BSI is i know they can be a weak link in the electrical system. when i was a pug tech i replaced loads due to electrical shorts and stuff and with it being a competition car i cant afford to have retirements due to faults like that. and as it stands at the mo i cant afford a stand alone system.

i know about the ecu unlocking because im going to be running push button ignition and getting rid of the key and immobilisher.

Im also simplifiying the wiring hence another reason to chuck the BSI and its in the way for the cage lol

Only uses the BSI for the immobliser, just looked at the Pug diagrams. Pins 4, 21, 22 on the BSI go to Pins 22 and 48 on the ECU, which are the immobliser. Never normally get that many problems with the non-plexed BSI

So in theroy the Engine ECU will still run the car. I assume all the dash instruments take the info from the Engine ECU. where are you getting the diagrams from because i miss not having access to PPS
