That is, but as soon as you put on an external box that modifies injection pressure that value will be wrong since the external box modifies it. The reading on the Outlook Monitor will be falsely low.

 

where can I get a rail pressure gauge?

 

SPA has made a custom one for some folks over at TDR and SP Diesel has one built into there power modules.

 

This all depends on whether or not the BDDL does any pressure or not.

The claim is that they don't. If that is in fact true then there should be no pressure worries when stacking.

Actually if they only do duration and timing the rail pressure would be lower than with just a pressure box. As you increase the injector pulse the rail will run lower pressures. This is why you see people needing and wanting to stack with a TST box.

Now if the BDDL actually does do pressure then it could be a different story. It all depends on what the downloader really does.

 

I thought someone on here did some testing with the bddl and it did not do press. on the tow setting but the other settings did add press.

 

if any of you have a meter,,why dont you tap on the sensor on the rail and check voltages while running....there are threads on here that show what voltages equal what pressures accordingly...most say that the stock sensor reads accurately up to about 26500 psi,and when it gets higher than that,you know its too high anyway...i had a thread where i checked mine this way with my quad tow box,you may wanna look at it also...do a search for rail pressure readings and try it,,,its free.............bama
