Stacking rail guage with TST

[WoodChuck]

Can I stack the Pricol rail pressure guage with the TST PMCR with R49 remote (it does rail pressure too)?

 

[JJPage]

Yes, I just stacked mine on top of the TST/EZ/RP GAUGE.



Works well.

 

[JVolpe]

I have mine stacked with TST and EZ also. The RP gauge should be plugged into the RP sensor first. Otherwise it will see fooled RP readings from the EZ or TST if you have that TST option.

 

[JJPage]

I believe JVolpe is correct, I think I did put the gauge first, as it will not alter the signal.

I'm looking to do the same thing. I'm sorry if i sound dumb, but when you say it should be plugged in first are you saying that if you had the EZ first you should unplug it, connect the RP gauge and then plug the EZ back in?

Yes that is correct.

I designed the rail pressure gauge harness to connect directly to the factory sensor on the engine. Then anything else plugs into that:



Here is the stock configuration:



factory harness ---> engine



and the configuration with a pressure box (such as the EZ, Quadzilla, MP8, etc. )



factory harness ---> pressure box ---> engine



and with the rail pressure gauge:



factory harness --> pressure box --> rail pressure gauge harness --> engine
