Since I've deleted my EBPV and my tube is all rotted, would the fitting that connects the tube to the manifold be a good place to put a pyrometer thermocouple or would it be better to cap it and drill a hole elsewhere?

Thanks

 

Very good question, subscribing......

 

are you talking about the EBPS the little sensor right in the front of the engine?

 

Yeah, I think he talking about the sensor. The tube goes down to the exhaust manifold. I have mine plugged as well and curious if that would be a good location. Not sure if the wiring would go that far?

 

good point grant, that would be ten times easier though. mines plugged aswell. i wonder if that would work becuase the heat in the manifold travels past the pyro up the up-pipes to the exhaust port on the turbo....in the front there is only goes up to the pyro and stops, almost would be enough space to move the air and get an accurate reading, im thinking that the heat would stay in there...idk just an idea

 

If the probe was in front of one cylinder you might not get an accurate reading because the the exhaust valve opening and closing. At the end of the manifold it would seem to reason that it would be more of an average reading. I could be wrong though....lol.....Were is Gene when you need him?

 

lol we could just have a convo back and forth till he gets here? hahaha, i see your point though, too bad i already did a crappy job tapping my manifold

 

Was it just keeping the tap straight. As long as it's not leaking you should be fine. I'm getting ready to do this soon.

 

i used the wrong tap by accident. it dosent leak, just need to get the 1/8" tap to do it the right way

 

Give me a call Philip, I have the manifold drill and tap kit. Grant, you too, just shoot me a PM if you need it.

 

I was thinking of getting rid of the tube all together and coupling the pyro to the fitting on the manifold, if that makes any sense? My sensor is zip tied out of the way since its not connected to the tube any more.

 

Update:
So I installed my pyro tonight(brand new Isspro EV2) and attached the thermocouple to the fitting on the manifold previously used by the ebpv tube. When I first started the truck it was saying around 100 then driving around town +/-250 then when I really got on it on the highway the highest I got was +/-350 so either somethings wrong with my pyro(any ideas) or its the location. I'll check my wiring tomorrow but I'm leaning toward the location of the thermocouple right now.

Thanks

 

I'd say that it's probably the sensor, because that tube should get a lot hotter than that! Is the probe in the exhaust manifold deep enough? Mine at idle is about 300, and at cruise (2100-2200 rpm) about 650, and when I stand on it I'll push it up to 1500 if I want.

 

The tip of the sensor is just about in the manifold. I think if I did a normal install with a drill and tap it would be in a lot deeper but you would think the sensor should still be getting hot enough.

 

Did you have to use an adapter? I was looking at the plug and I believe it was 1/4 npt. Definitely not a 1/8 on mine. I also saw that you should not cut and splice the wire. Hopefully yours was long enough. I would try at the end of the manifold.
