Electrical problems really suck. It all started when I got this crazy idea to paint my whole car. I disassembled the whole car. Every body pannel was removed, everything on the engine bay walls were removed, hand sanded, and painted.

Upon reassembling the car, I forgot 1 bloody thing. The little black ground wires for the ECU and ignition. They share the same bolt as the negative battery terminal in the engine bay. So, the result was a really week spark, whacked EGT's (jump up and down spiratically), and knock under boost no matter what the ARC settings were set to.

Here's everything I did to track the issue down after finding the ground wires not hooked up:

Vac reduction
Cleaned the paint out of the threads for the bolt hole.
Replaced plugs and wires (2x)
Compression test
Pressure test/fix leaks
Tested/replaced ignition coils
Tested/swapped out PTU
EGR delete
Tested Cam and Crank sensor wires
Checked timing
Pulled/examined ECU
Triple checked all wiring
Swapped out EGT gauge control box
Stock fuel pump relay delete/resistor bypass
Cleaned paint out the thread for the pleunum ground (and swapped in the correct bolt)
Many sleepless nights starting at the electrical manual

The car boosts .95 bar now with no knock till redline in 3rd and my datalogger works perfectly now. EGT gauge is still whacked. It probably needs to be replaced. Traction in 40 degree temps sucks.

I'm going to either GLD or Kaukana sometime this week, then the car is going away for the winter. My goal is to beat the 12.3@109 Matt Monnett ran in my car 2.5 years ago. Anxious to finally see what she will do (or break something while trying).

I had a girl friend like that once.

Did you break her?

That's awesome that you found the problem man!!

Now I want to see your car at the track before it goes bye bye for the winter.
Let me know when you will be running it and I will see if there's any way I can make it.

Get some race gas with the money I gave you and tear it up

Jason

no, she came broken from the previous owner.

I like a retard, got her cheap with the hopes of fixing her up.

Sigh, I know this problem all to well. Car and once a girl.

Electrical problems definitely suck.
I'm glad to hear you finally got it figured out. I'm sure you have already done it, but check all your connections for you EGT (at the guage,the control box,under the hood).
I think I finally have you issues traced down to the battery and the grounds are not the best shape either.

'94 vr4- Now with extra slowness

I went so far as to do a continuity check for each wire for the cable going to the gauge from the control box. The problem is either the gauge or the probe (probably the probe as it's well over 3 years old now and past its life expectancy).

b.t.w. When do you work at GLD next (or Kaukana)?



Dude, there's no repair manual for a woman. If anything, they make great daily drivers for a short time.

Yeah, I moved out of my parents house, and wouldn't you know it, a month later my house was dirty. I was like wft? I also noticed laundry starting to accumulate. I phoned my mother, who promptly told me I had moved out now, and needed to take responsibilty for myself. This meant cleaning and laundry.

On that note I went out and tried to find a girlfriend. Thing is, half the time they don't want to clean, they want to help with the mess. Once again, I'm like wtf?!? So I'm now looking into a maid. They are cheaper.

Let me know when you order your probe. I need one also. I thought I remember you saying something about getting one that responds faster or something...

You can have my spare Greddy one. I'm going with a TRE probe.

$hit, the girl I lived with was messy, and I had to clean up after her...
