This car appears to have been originally equipped with the dry-break refueling system. That is the vent connection for the dry-break. The dry-break system uses a dump can to quickly fill the car with fuel. It uses a spring loaded fuel cap that opens when the dump can is installed. A second line from the dump can is attached to the fuel vent connection.
Where is the location of the wheel speed sensor? My stack display does not show speed.
In this picture you can see two air intake temperature sensors, at the time of purchase of my car neither were hooked up. Which one should be hooked up or should both be?
Hi Josh (@meatman), To find the wheel speed sensor look closely at each of the front wheels and you will see a wire that comes over to the wheel hub. That piece at the end of the wire is the wheel speed sensor.
I am not sure why your car has two intake air sensors. What type of ECU does your car have? I believe you said in a previous post that your car is chassis number 96 and that it has a newer 1340 engine so I assume that the ECU and the sensors were updated from the original configuration when the K8 engine was installed. The usual place for the sensor is on the back side of the air box. The second sensor may be a dual sensor for the Stack system. I haven’t worked on a Stack car, but I understand that they run dual sensors that are redundant to the ECU sensors. Hopefully someone with Stack experience will speak up.
Also, I would recommend patching up the holes in your air box because that is allowing unfiltered air into the engine.
The ECU is likely on the front firewall of the engine compartment.
Is your engine carbureted?
Also, do you know what the engine serial number is? It is most likely stamped on the back of the engine case or it could be on a plate on the top of the valve cover. It will have a number like 1340-345. Here are some pictures that show the typical locations.
What looks like a MAP sensor is actually the BAP sensor on the firewall... I would imagine your ECU is a Life Racing...
In your last picture, the pressure sensor on the brake line is the brake light switch.
I have a car with the STACK sensor and a Life Racing ECU... On my car the Wheel Speed sensor is on the front left wheel and it is wired up directly to the STACK dash.
If you have a CAN connection between your ECU and STACK dash you could also wire the W/S sensor to the ECU (The Life Racing ECU has a compatible connector) and then read the W/S through the CAN bus.
That is a Gen 2 OEM Suzuki ECU. Also looks like Gen 2 OEM throttle bodies.
I would guess that someone has updated the car to a Gen 2 engine, ECU and loom.
I would be slightly worried that it is a road bike engine that has not had some of the reliability mods carried out.
With speaking with Charley and also a little investigating on my part the "upgrades" you speak of might be done. I will continue to investigate over the winter as well.
