Started the fan wiring loom. This will be ECU controlled.
Relay block here I think. Close to battery, close to fans, good earth point.
Wires wires wires
I got enough done to get the fans working from the ECU AUX 4 output, but I was short a proper fuse holder and connectors to the fans themselves to finish it porperly so thats still to do. The fans work though so thats a good thing.
Then I went on the the Zeitronix ZT3 AFR gauge, the lambda was an easy fit to the downpipe because I made the downpipe so the sensor would be easily accessible. The cable routed along with some other stuff i'd already laid, went through the bulkhead hole I made for the ECU and threaded with the ECU harness inside the car. I plugged all the pluggy bits in and all seemed good, until I powered everything up and it was giving a static reading of 14.7, no matter what I did to fuelling. Slightly confused a quick check revealed I hadn't plugged the sensor into the harness in the engine bay LOL.
Ive been using the map file form my own car as a base, and though it runs, it runs rough and is hard to start. I knew it was running rich, which is why I wanted the ZT3 in place. I had a bit of a think over xmas and remembered I took a copy of Johnspin and Dips maps when their ECU's were fitted both cars have cams as does this one (mine is still OE). Johnspin has some cossie old skool 0-280-150-xxx injectors but Dips I was sure had similar Siemens Deka injectors to this car. I reviewed the map file and the fuelling was about 40% less than what I was using, so I loaded the map grids only from Dips file to Amrits car (handy feature in the software that) and it was immediately LOADS better. Assisted by the AFR gauge we're idling stacks better now.
