G'day all...I'm new to the site, but I've referenced it in the past. After leasing 4 BMWs I finally broke the vicious cycle and bought one. As with every other, I'm pretty damn satisfied. I'm especially excited about tinkering with it being it's mine.
Anyway,
I bought a Magnum Dyno-Boost chip which connects to the O2 sensors on the exhaust. (So far so good). The directions also say to connect it to the signal wire from the IAT sensor to ECU. I have an 07 328i. I see the Mass Air Sensor, but not the IAT. I'm browsing different sites but I can't find anything on it. Does it exist or which color wire is the air temp wire on the Mass Air Sensor?
Thanking anyone in advance for their help. I appreciate it.
