EBPV revisited

[hheynow]

I find it humorous how I forget about my EBPV during warm weather. This morning's low was 22*F (I'm in California...gimme a break ) and sure enough my EBPV activated. Yeah I know many of you disconnect it, but when should it normally shut off? My water temp was at 190*F and the darn thing kept groaning.

Richard,

I think the EBPV gets its commands from EOT and IAT sensors. Water temp doesnt play into it at all.

Yep if the outside air is cold and the oil is cold it will "groan" away. Put a switch on it so you can turn it off when YOU want to turn it off

I got tired of mine doing that (it was probably 20F this morning). I gutted it, modified the "pedestal" to get rid of the actuator cylinder, and got the SP Dongle. I use the DIY AIC for warming it up (plus I plug in the block heater). Much better in my case. Cheers!

It was 22*F again this morning and she fired right up but once the GP cycle stopped I turned my chip to high idle. Man oh man was my engine loud . Sounded like it was ready to explode. If I plug it in at night (which I have NEVER done in 5 winters) will that prevent the EBPV from activating? I like the function of the EBPV but the groan is annoying.

How many watts does the block heater draw? I'd like to hook up a timer to turn on at 2am and off at 7am. Is 5 hours enough time for the block heater to make a difference or is over night recommended? Lows here rarely get below 18*F.

Yeah Richard, 4-5 hours is plenty. Off the top of my head I want to say our heaters are 1000W. It will help considerably with your warm up times and will decrease the EBPV activity. You also may consider cleaning the EBP tube, I dont know how much more you are sooting now that you are chipped.

5 hours is plenty - typically need 2 to 3. However, this will not prevent the EBPV from coming on. I have had mine plugged in the last couple of nights and it was roaring all morning yesterday. I love the block heater; it will prevent that loud engine noise you mentioned. I use it anytime we hit below 40 just to have the smooth startup. If you do that you could simply unplug the ebpv until the cold weather is over and then plug it back in. that is what I have done over the last year. I need to unplug it again.

Newbie question. Isn't the EBPV supposed to open when under part throttle? Or will they stay closed with cold ambiant air temps even when the truck is underway?

 

[Tx_Atty]

it will open during acceleration but close again once speed is constant.

Ok so mine is operating correctly. Time to put in manual control then. Thanks
