Project AE86: Updates

Since January, the AE86 has been up and running. I have have been driving the car on the streets and at the track. For the most part, not much issues, and it’s drivable. With this corona virus pandemic going on, I have a lot more free time to do some finishing touches and address some issues from last track day.

One of the things I did was change my eBay killswitch. There are some things you can cheap out on, but this killswtich wasn’t working properly. The car would still turn on even with killswitch hooked directly to the battery. I bought the QuickCar master disconnect, and feel more heavy duty then the eBay one. Best of all it, actually works!

Next I did was install electronic oil pressure sensor. I wanted to hook up all my sensors to the ECU. I did this for two things: one I wanted a cleaner look, and second is to set up parameters for limp mode if something bad did happen before I cause major damage.

I bought my sensor from Amazon. I later found out the pinout wiring that was on the picture was different then the one that was actually written on the sensor. The red wire goes to the 5v connection, the black wire is the sensor ground, and green wire is the analog volt channel. The custom engine harness I had made came with the connections.  I just had to make sure I wired it correctly. Then I configured the sensor via ECU. I told used one the spare analog volt channels and told the ecu 0v is 0psi, and 5v is 150psi. Works perfectly. If anyone is interested in my sensor here it is: https://www.amazon.com/gp/product/B00NIK98O8/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

Next on the list was install my AiM MXn dash. First track day in the 86 I didn’t have any vitals hooked up except my AFR. I wanted to make sure I was ready for the Driven and Blessed event and had to put a dash. My stock dash was incompatible with my custom wring and Link ECU. I thought ahead of time and had custom harness made with the ECU for a CAN BUS connection.

I chose the AiM MXm because its a dash and data logger all in one. Other AiM dashes was too expensive, and didn’t have data logging capabilities. The owner would have to pay extra to get data logging features. All the AIM dashes can hook up to OBD2 or, in my case, ecu via CAN BUS. The wiring was pretty easy. I had one chassis ground wire, one 12v power wire, and the CAN negative and CAN positive wire. The CAN pos and neg wires I connected to the engine harness I had made. Next is set up the AiM dash to read the Link ECU. Once that is all done, you can change pages on the dash to see the info you want, and custom make the screen and warnings to your preference. Nice and seamless.

AiM products comes with extra auxiliary outputs for expansions, or a smarty cam. I could have gone with other dash but this one cost less then $1000 which serves as a dash and data logger, all in one. There are cheaper options but I didn’t like the style or look of those.

With the corona virus pandemic going on, the world is definitely a different place. There is social distancing, events/venues canceled. Bars closed with restaurants open only for take out, or delivery. People are either working from home, or have no jobs. The only places where people allowed to come to work are essential businesses only. Hopefully this virus will pass, and life will return back to normal. Stay safe y’all.
