Ok. Exhaust is done to back axle. Ill try to snap some pics. 3 inch each bank. Inside frame rail on drivers side. Outside frame rail on pass side then back in the frame by the transfer case where I built a 3 to 3.5 " y pipe. Lots of piping and work. Its just mild steel but looks good still.
 
It's been quiet up in big D. How's it going?

So it took me two hours instead of one. but, now I can drive my rig on the stock suspension. :-P

It was so easy to take off that I decided to modify this one and put the money towards something else. I'll change it later.

Jeff: I'm using Goodrich black woven, stainless steel braided hose for my power steering. It's really expensive. Like 10 bucks a foot retail. I'm using Black -6AN fittings for my pressure side of the pump. I may go with a generic woven hose for my return. I'm thinking I'll need 4 feet of expensive stuff and 6-7 feet for the return lines.
All in all, when I make the line, I'll get a price from the boss man, who so kindly lets me tinker on my own stuff.

I'll install the pan this weekend if all goes well, but it's kina busy with family stuff.
I had to extend the pickup tube a little, and I removed the front portion of the lower sump. I have no idea what's gonna happen. I haven't even test fit it yet.

Nice welds on the oil pan! What are you using for your welding rig?

(sorry to hijack) :)
 
Well, we have a good ol' syncrowave 250. and my shakey hands. I'm not the lead fabricator up there either. If you want to see some really impressive welding I'll post up some of what Mike has done for the shop. Him and the owner Tony are the best welders I have ever seen. My main deal is wiring, tuning, and wrenching.

I am a tard for not getting pics together yet. I'm so close to driving it. After I pay the bills I'm getting ready to order wheels and suspension. ouch. Got any good wheel threads? hehe. jk. I want a more suburban mudder look, not so much of a crawler look, so I found some 20" wheels with really large tires I like. It says they'll fit. Do we have any wheel vendors on here?

FYI; we went to Houston to race and ran a 9.65 in one GTR, and in Tony's GTR he ran a 10.10. Pretty good for street cars. Oh, and we drove his car down there and back.
Here's our You tube channel and the AWD dyno I'll be using to tune the land cruiser.

Congrats!!!! What suspension you going with?
 
I am not happy right now. I did drive it home and boy it's nice. But, I have an intermittent U0107. TAC module stuff. I know I know, throttle cables don't have DTC's.

harness is unsheathed at the moment, so kind of embarrassed of how the harness looks right now. It's a nice day out so I'm working feverishly MUST GO GET JET SKI'S and I can't do it until it runs. ;)
 
When I was having problems, I found there is a common problem with the wires into the Throttle body and the TAC going bad. Check 4 to 6 inches back. If you think your TAC is going bad, I have an extra one you can have.
 
U0107 is the code.

Well, I have the scanner on it and it shuts down or goes into limp home mode at 35% APP or Pedal Position. I had an auxiliary DVOM on it while I was performing a pedal sweep and the numbers didn't glitch at all. We actually ordered a $2,000 scope for other projects around the shop, so maybe I can use it for this as well..

I noticed that the ground side of the module gains some resistance right when that happens, so I'm wondering if there actually is a short inside the tac module itself. I ran a new separate ground from the module today and tested various wires on the 0V zero volt signal circuits and they all check good. The only odd thing I have going is the high resistance when the pedal and the throttle reach about 35%. This spike is on PIN 15 of the TAC module going to ground, and not either sensor. Possibly something going on with feedback? or a short internally?

My instincts keep leaning toward feedback when the throttle motor needs to be driven from 35% and higher. Strange that 100% Doesn't affect it at all. I thought it was the tune ( could still be) but doubt it. Only thing I did wrong wiring wise was miss a ground for the o2 sensor. That was easy. This has frustrated me cause I want to go to the lake (selfishly) and can't go get the jetski. :(

google is usually my friend, but not this case. I'll PM you my address and you can ship it to me. I'll buy it from you if you don't need it. Has to be the right year, I think 04-06?
 
Do you have a truck intake or car? The throttle body wiring is different between the 2.
 
Double-Check pinouts-- Error indicates PCM confusion on inputs

Wayne,

For some reason, GM used the same connector but different pin-outs on the TPS/ETC wiring depending on application-- car versus truck-- some years.

The LSx and Swap forums are pretty good for information. The excerpt below is from one of the Toyota-GM swap lists.

<<SNIP>>
The pinout assignment for the LS2 DBW is as follows:

Pin A = Motor (Aux1, Fucntion 5)
Pin B = Motor (Aux2, Function 6)
Pin C = 0 VDC
Pin D = - Signal (TP2, this signal is inverted from normal ie, 100% - 0% when fully open)
Pin E = +5 VDC
Pin F = Signal (TP, Signal is normal 0% - 100% when fully opened).


The pin out for the ETC pedal ( 06Vette-ETCPedal & 06Vette-ETCPedal2) is as follows (when reading the connector with the locking tab on top)!


Pin 1 = +5V (TPD2)
Pin 2 = Signal TPD2 (TPD2, is inverserve of TPD, when TPD = 0, TPD2 = 100%)
Pin 3 = 0V (TPD2)
Pin 4 = 0V (TPD)
Pin 5 = Signal TPD
Pin 6 = +5V (TPD)


CAUTION: Be aware that the 2005 pedal LOOKS the same but the pins are not the same! In the 2005 pedal assembly, pins D & F are higher resitance value than pins A & C which is the exact OPPOSITE of the 2006 model Throttle pedal assembly!!

Of course you should always TEST to make sure you did not cross any wires or assigned the wrong output to the wrong pin (on three points, TB, ETC pedal and the MoTeC).

<<END EXCERPT>>

Motec? where's this thread?

I can watch the throttle position go from 0-100 in the EFI live scan tool when I manually grab the throttle plate. I'm pretty sure it's ok. If not, I'd get other codes as well. I'm pretty sure I'd get codes for the pedal too if it was wired wrong.

Hmm I wonder if it is in the tune.......... I wonder if it is looking for another computer....like TCS and doesn't see it and freaks out.

I'm going to go make sure that I turned off TCS and stuff.

Wayne,

I'm looking for a wiring diagram for you, but the LSx crowd generally re-wire this one pretty easily... It's odd that they built multiple (non compatible) versions but it's only two pins if this is what's causing you grief.

Which PCM model are you using? Sounds like it's pre E-38?

Ok, I just realized I have an 2004 ecu and operating system and a 2006 pedal and TAC. SO. I'm going to try to load a different operating system and see what happens.
