Great job! How did you bypass the theft deterrent module or did you incorporate it into your column? I know that with GM cars the theft module sends data to the body module which tells the ECU it is ok to crank/run. If you were local to me I would have programmed your ECU at no charge. My boss would have thought it was cool and let me do it on the side.

Thanks guys!  This has been a huge test of my patience, and a culmination of what I have learned on previous projects.  Itís coming out much better than I was expecting.  The hard stuff is done, now for the millions of little things that need sorting out.

Jinx, if I put the same effort into a G54B, it would never pass CA Smog visuals lol.  I certified the 4age in the Starlet about 5 years ago.  Was a lot simpler to get done, as itís pre-OBD2.  Basically doubled the horsies of that car with a stock engine.  About 120hp in an 1800lb rwd car.  Also running AE86 suspension/brakes/LSD.

Cary, luckily, it had the most current PCM flash!  I kept the VATS in tact to add layers to my vehicle security.  I did omit those details here in the thread for obvious reasons.  The BCM was needed first for me to run the GTO IPC(cluster), and as I went down the rabbit hole, found itís also needed for the VATS, and air conditioning request signals.  I may try to hook up the antenna and run the keyless entry through it too.

The "antenna" may need to be programmed. It is called the Remote Control Door Lock Receiver or RCDLR. You'll just need to wire a few wires to it. One is Class 2 or Low Speed network wires to the BCM, the other is power and ground. The remotes will need to be programmed to the RCDLR.

Basically when you hit the remote the RCDLR checks the fob signal, verifies its programming, then sends the unlock/lock request to the BCM.

Now as for actually operating the locks you may have to get a door module to do it. I dont know the specific schematics of your year range BCM off the top of my head and how it controls the locks.

If you need any OE diagrams then PM me your model and year BCM info and I will pull them from GM service information. I can also get you connector end views which also list all terminal types and part numbers.

I recommend hooking it up! Having keyless entry, alarm, and remote start would be great. It would be an OE system all working as it was designed so you shouldn't have too many issues. I have seen VATS pass lock sensors fail but that's about it.

I was thinking about just getting the GTO fob, and cutting/tapping a Mitsubishi key to fit it.  The fob itself can be manually programmed in car, without a tech2, but it takes much longer.  I still have the antenna and key slip ring from the GTO, so Iíll play with those later. The antenna harness is also still connected to the BCM and tucked in under the dash ready to go. Donít remember seeing any door modules in the diagrams though.  The GTO is still pretty simple compared to todayís systems.  The fob only has lock/unlock and trunk release, so Iíll most likely delete the hatch cable/lever and run a button and solenoid instead.  Itís all pretty low on the priority list though.

I don't see why the GTO key blade couldn't just be cut down to match the Mitsubishi key. As long as the pass lock chip is ok then it should work.

The GTO key is a completely different shape compared to the Mitsubishi key.  Would be easier to cut down the Mitsu key to mount it inside the fob.

The inspection takes much longer than the usual smog check.  Everything has to be verified.  OBD data was analyzed, and actuator/sensor functions are checked bidirectionally with a scan tool.  Inspector said about 95% of swapped cars that roll through don't pass the first time.  My wife and kid helped to pass the near 2 hours it took to inspect.  400hp and smog legal...

Getting 26-30 mpg at 65 mph with the cruise control on.  Not too shabby.

Weighed the front and back of the car with almost 3/4 of a tank of fuel in it.  No front swaybar yet, AC evaporator assembly in, no engine oil cooler+accusump+remote filter...this thing is near the same weight as when it was G54!

Weight when I brought the car down November 2017 with near empty gas tank.

Im nowhere near ready to paint the car, but I thought I would put a new emblem on anyway LOL

Now for all the million little things to make and fix.  The hard part is done!

Just an amazing job.  

I couldn't imagine having to go thru all the checking/testing.
