Vr bt1 ecu

[vs hay hauler]

I tryed to put a standard ecu into a bt1 pack commodore, the problem i am having is the plug fitting on the bt1 ecu is different than the standard has a metal plug fitting in the ecu they wont interchange. i have opened the standard one up and it may be possible to change the plug fitting over.
has any one had this problem before or changed the ecu female plugs?

BT1 ecu is a RFI shielded ecu. Just out of curiosity why do you want to swap ecus?

The ECU sockets are soldered to the board in the ECU so swapping them would be very difficult unless you have a really good soldering station and are very experienced at soldering electronics. You could cut the RFI type plugs off ,and resolder the normal plugs back to the wiring harness. If you do this, make sure to use heatshrink tube over the soldered joints, just dont tape them, tape wont keep the soldered join airtight,this can cause the join to corrode and you end up with bad connections.

I would avoid soldering the wires to make the connection at all costs, all the sensors feed the ECu with 5V for their function with small millivolts of fluctuations the computer makes adjustments on the run, solder will increase the resistance, lowering the volts of signals received by the ECU.

I believe you can remove the lug that locates the harness connector, inside the connector to make it fit but I have never tried it.

Computers are cheap, IMO get the right one for it.

I'd get the correct BT1 ecu, so then you get the cop chip as well

You can't have the cop chip if your on your P's as it pushes the car beyond the 200kw limit.

The car has some sort of electronic gremlin with engine light coming off and on. car runs fine with engine light on and misses and flares slightly when its off.
maybe the computer??? has error codes of 41,59 and 72 have replaced ignition module , distributor and a speed sensor on the side of the gear box.
Has now got me stumped and i am starting to run out ideas, all help much appreciated.

Solder increases the resistance ?? I had better scrape off all the solder on the circuit board as well.....

The tracks aren't made from your usual lead based solder.

[VR38]

Any connection has the potential to increase resistance, mechanical connectors being worse than solder tho.

[woteva]

The resistance of a typical solder joint will equal less than 0.00001 ohms. Huge resistance there, so better stay away from those solder joints and go for the scotch loks.

I love those things. Always makes customers come in when they use them and they inevitably fail. Most dodgy way to do things.
