Actually, there are people who have disassembled the Toshiba 8X ECU code. Unfortunately, they live in Japan and it is tough to read their web site if you don't speak Japanese! You can even buy a disassembler for the ECU for about a $100. Here are some links...

What experience do you have with electronics, and what tools do you have to debug and test?

"Bulbs" going out is typically due to cold solder joints in the CC. Run a soldering iron over the dead LED solder joints and it will most likely come back to life. Here is the climate control color change thread on SF: http://www.supraforums.com/forum/showthread.php?t=163505

No they don't. The oil galley goes up from the front of the head to the two #1 cam bearings. That is it. There is no oil galley down the center of the head. All they seal is crankcase pressure/vacuum and that can be handled by FIPG on the threads..

The back plug has a lot more meat behind it for the threads. The other plugs are very thin. Any attempt to tap them will results in a hole right through the plug with only a thin threaded length. However, given the the fact that the plugs don't really seal anything, and the loads are light, I...

You should start by checking for codes.

Lemma: You never really fixed the code 14. You thought you did, but clearly you did not or it would not be back. Check the igniter circuit per JJ's instructions.

Ya know, ya had me purdy close to kern-vinced for a minit but then I dun realized yoo can put yer gol-durned feenger in dat hole ter slow her down.

Ahh codes... now I had assumed since this problem has been worked for some time that any codes were long ago cleared. You need to fix the 14, no question about it. Based on your initial post this has all been checked, so how can this be? Something is not quite adding up here. By the way, a...

I guess I have two points: 1) Are you 100% confident the injectors are not firing, and how did you come to this conclusion (specific tests). 2) If yes to above, first thing to check is if power is getting to the injectors. This is an easy test with a voltmeter. Pull an injector plug, turn...

When you say the injectors are not firing, is this based on an electrical test or an audible test? If electrical, have you confirmed 12V at the yellow (or blue or red) wires of the injector plugs with the plug disconnected and ign on? Have you tried jumpering the fuel pump on at the diagnostic...

Well, the LED center light basically removes one 27W bulb (1156) from the circuit. Hence the 27Wx4 instead of 27Wx5 designation. The four taillights are 8W each, so we have the 8Wx4 for them on all models. Note that an 1157 bulb draws 2.1A at 12.8V for the stop filament, and 0.59A at 14V...

That cable, plus the one at the latch, connect at the key lock assy. You need to remove the tails to get access. In my case I replaced that cable assy and it all started working again. However, I believe that you can place a shim between the plastic case in your hand in the photo, and the...

There is a seal in the CPS that goes after 15 years or so. Here's my post on how to fix it. http://www.supramania.com/forums/showthread.php?t=44846 But..... you should not have pressure in the crankcase if the PCV is working properly. Does this engine have cylinder leakage issues?

I can't see the pin shearing off unless the bearing seized solid. Its a 4mm steel pin! I would check the press fit of the top reluctor on the slim chance it is loose and rotated. Otherwise, I think the gear itself jumped relative to the cam. Possibly due to a worn bushing on the CPS, which is...

What LEDs are you using? I have been experimenting with a few and like the OPTEX OVSPxBCR4 Series. The red is 26 lumen at 1 watt. But now I am having second thoughts that they are too bright. http://www.optekinc.com/pdf/OVSPxBCR4_Series.pdf

Induction hardening is a form of heat treatment in which a metal part is heated inductively and then quenched. The quenched metal becomes harder. The inductive heating limits the depth of the hardening, without affecting the properties of the core. To my knowledge this technique does not...

The technical jargon is "inverted buckets and shims". But.... and this is a nice twist to an otherwise dubious thread, the TSRM calls the inverted buckets "valve lifters", and I do quote thus: http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=EM&Page=32

Not to be an ass, but nitrite is what you use to make hot dogs! You use nitride (usually silicon nitride) for cutting tools and the like, due to its hardness, thermal stability, and resistance to wear.
