A customer of ours came by from a trip to Japan to have us install the new Super AFC into his Second Generation (1995-1999) Eclipse GSX.





This unit is not currently released in the US, but with careful translation, we were able to install it without any problems. If you have installed a Super AFC, an AFCII isnt much harder. Upon initial looks, the unit looked to be much of the same AFC with different styling. We found it had much more to offer after operating the unit for 10 minutes. With more granular steps and more finite tuning steps and much more features this is a must buy for any racing enthusiast. We begin with the first of our 3 step writeup on this product, from Install to Tuning we will cover it all.

The Tools you will need to install the Super AFC II into your 2nd generation GSX

• 10mm ratchet

• 1 Phillips screwdriver

• 1 Standard screwdriver

• Wire Strippers

• Solder Gun

• Electrical Tape
  ** Or taps if you do not wish to solder

The Super AFCII wires we are working with in question are

ooooooooRed Wire
PowerBlack Wire
2nd GroundBrown Wire
1st GroundGreen Wire
RPMGray Wire
ThrottlePurple Wire
KnockPink Wire
Air Fuel to ECUOrange Wire
Air Fuel to Sensor

Here is a second generation Eclipse pinout with corresponding AFC wiring.

Begin with sliding the driver seat all the way back until its furthest point. Look down at the driver side foot well and remove the plastic cover to the screws holding the side panel on. Remove the screws using the screwdrivers or 10mm ratchet.




There is a plastic pop rivet by the driver seat, slide your hand into the opening and tug to pop it out. Remove the entire panel




Inspect and arrange your AFCII wires




Remove your ECU plugs by depressing the tab on each individual tab.




Locate the ground tap pin 26 and strip the housing back to expose the bare wire relatively close to the ecu harness side. You will solder / tap the brown AFCII ground wire here.




Do the same to this ground wire, only put the black AFCII 2nd ground wire FURTHER away from the ecu harness side than the brown wire. Be careful not to mix this up. Then strip and tap pin 25 for the red AFCII power wire.




Tap pinout 58 for RPM signal with the green AFCII RPM wire. Then tap the brown wire with red stripes pinout 84 with the Super AFCII gray throttle wire for the throttle signal.




Cut the wire at terminal 90 in half but leave enough on both ends to play with. Attach the ecu side of the end of the cut to the pink Super AFCII wire. Connect the harness end to the orange Super AFCII wire.




Tap the purple knock wire to the ECU

Tape everything up with electrical tape nice and neatly. Zip tie the AFC harness securely so as it doesnt interfere with anything.

You will find that the new AFC has many new features, many new options and tools. First most the new AFC uses a thumbstick in the middle of an operational dial to navigate through its many menus. Depressing this thumbstick at any time will bring up a 4 way option screen CANCEL > Previous > Next > Menu. In most instances a tap left or right on the thumbstick will take you to the previous or next screen easily. Our next segment will go over how to tune your car for knock, how to change to finer resolution in low / high settings, how to set passwords, how to set your warnings, how to use your datafiles and much much more. We will leave you with a few screenshots until then :
