2010+ Mazdaspeed 3, I recommend to monitor your fuel pumps closely

The DH still is able to read some things on our car but it is really laggy. I used my friends DH to monitor FP when we installed the cp-e HPFP to make sure everthing was good. It was really choppy. It doesnt read AFR or KR. But it will give you a few things.

Hey men how where you able to log the FP with the DH. In mine it's showing N/A. Didn't bother logging parameter that doesn't display.

Please explain..

Sofar DH is reading only Boost, ltft, stft.

Thanks

For the most part it monitored all the basic stuff. The big things it didn't monitor was Actual AFR, KR, MAF Voltage, MAF g/s, Boost Temps. But like he mentioned, it ran choppy as shit. Not only that but when we switched it between his MS3 and my MS6 it freaked out. It showed many PIDS were missing most likely from the gen 2.

Are you monitoring the correct fuel pressure parameter? There's like two of three of them. It should be the one that says Fuel Pressure Direct Injection.

OK I was reading the wrong fuel pressure param. Yeah, DH is reading the Fuel Pressure as stated above.

May be we should create a sticky thread for the parameters, their meaning and what should be they OK values to point out to newbes like me what are import and on what to focus when starting messing arround with their car.

This is the last question about login. Knock retard with DH: Which PID parameters read it and what should be the OK value?

Thanks to every one.

I monitor DI pressure, boost,a/f ratio Long term and short term fuel trims Dash hawk has allot, but I have notice sometimes when you plug in you have N/A in couple of boxes. This happens rarely but all you have to do is shut engine off and then unplug, then restart car and plug back in after couple of minutes.
