So it passed California smog at the referee almost without issue. I had to go back a second time for basically no reason, but it passed. So I'm getting down to the 02 sensors or the AFM. I only have a digital multimeter, but measuring voltage from the primary 02 sensors at warmed up at idle...

I just watched the video....holy smokes, is the engine even bolted down? It should not move that much when being started. Looks like it'd rotate all the way over if it actually had a load on it. Mine doesn't even wiggle, I don't use the lexus mounts though specifically to avoid the engine...

That speed sensor has a four prong rotor on the output shaft, although I haven't tested the sensor function. Suffice that the tranny did shift, and never threw a code when it was in it's donor vehicle. I don't think I'd go through the trouble of wiring up a live data system for the engine...

I'll look more into the EFI main circuit tomorrow as well. There are only two stepper motors I can think of on the engine, the EGR and the ISCV. The ISCV circuit hasn't ever been touched from the factory, and the EGR I wired up according to the schematic. It's only 4 wires to the ECU and two...

It did until today. Now it idles just as slow cold as while warm. All I really did today was give STA 12v while cranking. I found that I had already wired STP and NSW last year when I first put the engine in. Granted that NSW isn't connected to the shifter, the ECU doesn't know the...

I actually just gave up on getting the ECU to control the tranny, so I pulled the pins to the two primary shift solenoids from the computer and wired them to a pair of toggle switches. For the first time I have first gear while stepping on the gas. :) Now I just gotta get this engine to...

I thought about installing the fuel pump controller when I putting the LS fuel pump in the truck. Seems a lot of people have problems with the controller failing, and while I know I could hotwire the pump on the side of the road, it just seemed like something extra to fail on the truck. I...

You know, thinking back to it now, I pulled the engine and ECU from an LS planning on running that drivetrain, but ultimately changed my mind and bought an SC motor on Ebay because I wanted a newer low mileage motor to start with after having so many problems with my previous 7M series swaps in...

So I verified that STA and NSW both have 12v only when cranking. Yeah, NSW isn't hooked up to the shifter, but it's function is identical to the ECU. It thinks I'm in neutral until the engine is started, and that's all it really cares about anyway since there is no signal to it when driving...

My LS had the 40 pin connectors, and plugged right in. Aside from the difference in the EGR system, everything else seems to have been the same so far. Next time I'm at the junk yard I'm gonna pick up one of those KD switches and install it. Although I would think that it would be capable...

I'm out looking at the truck right now, and checked NSW. I have it wired so that it receives power in the "start" position only. To me this makes sense, as it makes the ECU think that it's in park or neutral allowing the engine to start. I don't know what other use for this wire there is...

I keep thinking about this switch, but haven't figured out a good way to implement it in my truck. I didn't even think to pull it out of the donor car than gave me my tranny, since I don't recall anyone else having put the thing in when doing their swaps. Since for the most part people...

I do have a check engine light and fought with code 71 for some time before figuring out that the ECU wanted the stepper motor for the EGR instead of the VSV controlled one that was on my motor. I'll have to look at STA again a little closer tomorrow. I thought this was just to control the...

The ECU has the three 40 pin connectors. I guess you could say the larger one has 80 pins. The loom for this engine is all in tact from the factory. Nothing was changed aside from the few wires for power and the gauges. I have gone over all the power connections to the ECU several times...

Moving the shift lever down into "L" will give me 1st only when I let off the accelerator. Otherwise it starts in 2nd and upshifts from there. While in drive ("D") it simply skips 1st gear altogether, and wont downshift ever. I've tried two different ECU's, same thing with both of them...
