DIY scan tool for early ej22's
DIY scan tool for early ej22's
so this might help alot of people here that do EJ conversions. this is not my idea/product, i just tryed it and it worked and i think you guys will enjoy it as much as me
so to build this you will need;
that is a 25 pin printer cable, you cut one end off (the female end).
you then using a multimeter (set it so it beeps is best for this) trace all the wires back to the plug, you will only need 3.
looking at these 2 diagrams you can see what wires are needed from the cable and also the wires they conect to on the diagnostic plug (colours on the car diag-plug dont seam to differ)
now you can wire this in after the diagnostic plug on your subaru, leaving the cable in there permanent (if you only have the one subaru)
or i have (just now) made mine plug and play by using another female plug found in the drivers side kick panel.
found behind here but on a liberty not a vortex
of this plug only 3 wires are needed and one of those needs to be moved. easy with something pointy.
wire it in such a way as stated above, solder/tape and look pretty.
at the end you should be looking at something like this

now the second part requires a old laptop, or your in luck if you current one has the old printer port like the one below
the cable you made before plugs there.
now the only complex part of this is making a bootable usb from a image (iso image.the program wont run in windows, i have tryed) if you know how to do this great, you will find the iso file here;
http://www.surrealmirage.com/vrg3/b10scan/b10scan.img
google making "bootable usb" and you will find free programs to make the usb with.
now in order to use this you need to hook up the cable and usb, on start up go to your boot menu (normally f12 on start up) select the usb to boot from.
it will give you a hello screen and diagrams, hit enter and select the parrallel port connected to the car.
start your car and watch all of your cars info in real time by hitting space to cycle through views. read error codes past and present.... and even better, clear them with the press of a key!!!!!!

I sold a heap of cables like this in the past. I still have parts here actually if anyone wants one.
If you want to go USB use a FTDI FT232R based USB serial adapter. Pretty much every other brand will give you trouble.

Old laptops are only about $50 on gumtree if that, doesn't even need a hard drive because your booting from a USB.
There is a better interface that works with a USB cable, gives all gauges on a single screen at one time. But that was more work than 3 wires with some solder.
In this case;
Cable : free
Plug : free
Laptop : free
I can't complain, other than I wish I did it sooner!

This is a screen shot of the evoscan program that can be accessed by a USB cable. The trick is to get a USB to serial converter that will support TTL. FDTI is one that has proven to work. Trick is that the memory location of the ECU changed a bit over the years and between models, so it takes a bit of trial and error to get it to work

Just what we need for L Series EA82 mpfi. Um, Nev, OBD may only have been a Californian dream when our stuff came out. L mpfi have those diagnostic plugs I, II, II IV, V and VI that are scattered about. Me has one connected to the Volt gauge monitoring the knock sensor output - still need to test it with a hammer blow to the block. Normal readout is supposed to be 1.7V , my multimeter is reading 1.69 so gauge sees a lot of 1.6

it doesnt matter that the software wasn't designed to work with USB. It is designed to work with a serial port. So get a USB serial port..

You could get other software to work via USB, but you might need to pay for it.
