Default Apex'i Turbo Timer (w/ Voltage & A/F meters)

Since no one has reviewed it yet, I'll do one.
The unit is very nice, and as you have probably seen, is also very small. You can put it in a number of locations because of this... some people put it next to the cupholder, but this requires cutting up the dash, so I put it right in front stuck on the gauge pod at the bottom... It's a very nice fit. See pics at the webpage at the bottom of the post.

The unit was easy to install, using the HKS harness I also got with the unit. It's just plug and play with the stock ignition harness. I didn't use the gray wire (E-Brake sensor) on the HKS harness because the Apex'i came with it's own. Modifying the factory alarm was also easy, just cutting and taping off the two wires, 1 on the keyless entry, one on the alarm brain. The only thing that made me a little nervous was tapping into 2 ECU wires for the A/F voltage and ground. However, it was easy,... Just take your time and strip about 1/2 in. of sheathing and twist and tape. Nothing to it.

The unit itself provides 'warnings' for voltage and A/F ratios (which by the way, are 'theoretical' according to the instructions, calculated from the voltage inputted from the ECU wire you tap). These warnings are manually configurable (ie. You can set voltage warning to 12.0v or 12.9v or whatever). Same with the A/F... The joystick control is very easy to use and may take 2-3 minutes to learn. The A/F meter will display either the voltage (0-1 volt) or the 'theoretical' voltage determined by the unit. This requires 'calibrating' the unit, and I have not seen anyone that has successfully done this, so if you have, post here so we can all share.... I haven't calibrated it and my 'theoretical' A/F goes between 10 and 20, so I know something is up.

The timer has a manual (0 sec - like 5 minutes or something riduculous like that) as well as an automatic timer (which calculates the cool down based on your driving. The automatic mode is semi-configurable, meaning you can set the min and the max. times, and it will stick between those when it calculates the cool down time. During the cool down if you release the parking brake the car shuts off automatically, so no one can drive away in your car.

The LED's light up red, so they don't really match the green dash, like say the Blitz does, but it doesn't look bad, and the small size makes up for it. Overall it is a very nice piece, and if I hadn't wasted like 3 hours trying to dremel out the space next to the cupholder, I could have had it installed in 2 hrs. max, taking my time, especially with the ECU wiring. I paid $80 shipped with the harness (opened, but never used) from the For Sale classified's here on i-club. New ones are around 110-120 with the HKS harness... It's worth it considering you get a warning voltage gauge and MAYBE an A/F gauge, if I ever figure out how to calibrate the damn thing. Until then, I will leave my display on voltage.

All said, everything works as described, and does not interfere with the factory alarm.

Default Correction

If you cut the grey wires described above, it WILL affect the starter kill functionality of the stock alarm, i.e., it will not exist. There are some workarounds--hooking up relays and such.

If anyone has detailed info on how to do this, post it up!

I must concur with the review, as I have the same thing on my '91 Legacy GT.

However, I have some 'missing' voltage somewhere, though I have yet to determine the cause. At the battery, a DMM showed 13.8ish, and my Apex'i was only showing 13.4ish, about a .4V loss. As I said, don't know where this loss is, but I plan to find out soon(hopefully).

As for the A/F ratio, mine seems to do a decent job of showing accurately on default settings. ECU maintains it at, what the Apex'i is reporting, 14.7. I believe this is what the ECU is supposed to maintain, and if so, this makes the Apex'i accurate.

Other than that, it is a WONDERFUL unit. I mounted mine just above the air vents for the driver, next to the instrument gauge. There's a pic(somewhere) of it on my website as well.
