Cold start is still important in the winter mornings, but it just takes a little cranking to get started. On the thermostat housing Im only using the ecu temp sensor and the coolant gauge sensor. Cleaned out the idle adjustment port and adjusted timing and idle to 800rpm warm and afr at 13.6

Got the car running, dont need the thermotime switch, cold start injector, or egr. AEM Uego says 10-12 afr at warm idle. As for that coolant sensor, no idea what it does but I dont have it. Car runs just fine though.

Hello, I have a 77 280z that I've had sitting for a while now after I spun a bearing. I have a new motor on the stand that is rebuilt, just have a few questions about some modifications and the sensors. I have no egr, a hooker header, but everything else is stock. First, I have a blockoff for the 7th injector/choke. Can i get rid of the thermotime switch? My understanding is that the switch only keeps you from flooding the engine on startup by disabling the 7th injector. Since I have no 7th injector, more cranking time may be required during colder days. Second, Im using a ka24de throttle body, can I get rid of the BCDD? Obviously it has nowhere to go on the new throttle body. Third, one sensor on the thermostat housing (it has a single wire, is bigger than the others, and is mounted higher) the wire for the sensor came off. What is the sensor and what does it do?

Also, how about a blinker control switch? Anything out there under $100? I just need to pass my safely inspection

Does anyone make a new hazard light switch for a '77? Or has anyone used one off another year/model to work?
