ok, i started a topic about a week ago about doing a swap from obd2 to obd1, where only the block is involved. everyone told me that nothing needs to be changed electrically but the ecu jumper and ecu. now that i am taking everything apart, the obd2 block has a crankshaft sensor and the obd1 block doesn't. i know that without it, the car will run like crap. is it safe to drill into the obd1 block to modify it or what else can be done?

 

anyone?

 

if you using an obd1 ecu your ok it doesnot have a crank sensor just take it off or leave it. eric

 

no, for now, we'll be using an obd2 ecu.

 

I heard the obd1 cars have a crank fluctuation sensor built in to the distributor and that is why they have 2 plugs going to the dizzy. Is this correct?

 

if your using and obd-2 computer,then yes you will have to use that crank angle sensor.all you have to do is buy a obd oil pump and put it on your obd 1 block and your done.if i were you i would just go ahead and spend the money and get the jumper harness and be done with it.

good luck with your set up.
