did you ever look at the explanations of the SAE standards? this is from volvo website :
... Max power at, r/s (r/min) 32,0 (1 900)
... SAE J1995 gross, kW (hp) 122 (166)
... ISO 9249, SAE J1349 net, kW (hp) 121 (165)
only 1 hp between net and gross!! still nothing to say?
Thanks for the info circuit1952. But I am still confused I have examined the pages, they all talk about the change in resistance as the temp changes. My sensor has only two cables. One is the ECU return and one for the signal. without a supply voltage the change in the resistor means nothing to me
Hi everybody! Can someone inform me how does passive temperature sensors work (without a supply voltage). It has a resistor in it and the resistance changes according to the temperature but where is the voltage source ? (If I'm not wrong the pull-up voltage in the ECU is only to determine the...
Hi everyone. I'am little bit confused about these standards. J1349 should be the net bhp of an engine calculated from crankshaft with all accesories installed (like waterpump , alternator, etc). And the J1995 should be the bhp from same where and no accesories attached which is called gross...
