Hi Folks,
I am in the process of planning an install of M800 in to an E30 M3 (1990) and would like to figure out a few functions.
1, I have a oil temp sender (bosch) connected and intend on logging oil temps. Can I use a PWM Aux Output switched to earth, effectively emulating the stock senders resistance to earth, to give me a reading on my oil temp gauge?
2, I have a Carbon Canister purge Valve which on the stock ECU is energised for a period of time (60secs I think) on start up and then remains closed until the next start up.
3, The Valve is fused and has a resistance or 23.5ohms, so shouldn't draw any more than 1amp. Should I use a relay?
Many thanks
Steve
