Real time data HPCR #'s

Real time data



--------------------------------------------------------------------------------



Drove into work this afternoon with the Diablo as a diagnostic tool just messing around.

Picked out the HPCRpressure mode and watched as I drove.

In park at idle, I was seeing 46. 00Mpa-48. 00Mpa which I believe is 4600-4800psi.

In gear at idle, pressure was bouncing around between 5300-5700psi.



I wasn't able to go full throttle at all, nor build more than 10lbs of boost due to traffic conditions.

I did see the highest pressure in the 14,000psi range but most cruising speeds of 35-45mph and it was reading between 9500-12000psi.

I'm going to keep a log to see what highest pressures I see, what average cruise pressures at certain mph's, etc. .

Then, when I re-install Quads XZT (after they change the tune), I'm going to see if it'll read any changes.

There is alot of cool stuff to monitor with this programmer.

This might help with the MPA to PSI convertsion

Keep in mind you'll be reading the fooled values the Quad box provides to the ECM. The only way to accurately monitor rail pressure is to read it off the rail with a rail pressure gauge (SPA, Quad Monitor, MP Display, or soon--DLeno's DiPricol Optix).

Thanks for the link. So the pressures are higher than I thought :--) .



I kinda fingured they would be "fooled" by the box, but I'd like to check anyway... maybe they come in sooner in the rpm range? Don't know if I'll be able to see that either...
