I traded my old car for a 91 EF with an ls/v and im learning about as i go along. The other day i noticed the vtec pressure switch isnt attached, in fact the plug is no where to be found. I did some research about bypassing it, but thats for the JDM motors that dont have pressure switches for some reason. But my head is a '99 B16 head, so any info would be great.

 

Oh and its got an JDM OBD1 D15B ecu

 

Wait, did i just answer my own question? The ecu is from a JDM motor and thus it never had a pressure switch and thats why its not hooked up on my motor? Im a genious! But seriously i would like to know what the deal is.

 

please tell me your car is tuned, and that you're not running off of the d15 maps... lol you could be on to something tho...

 

That would be correct. The jdm ecu's did not look for an input from a pressure switch. Like the person above me said I sure hope it's tuned and you're not running your ls/v off of d15 maps.

 

yes its chipped my buddy who works at a shop put the same tune on it that he has on his ls/v, dont really know too much about it though

 

If its chipped they probably deleted the option for the Vtec Oil Press Switch. So even if it was a US ecu it wont look for it.

 

ok that makes sense then
