Steve, yep, agreed; tuning is the most important thing, as without it, everything else before it does not function properly. And, I found another surprise last night. It is in the shift points not matching up with the TCU Digital shift inputs, so even though the transmission is working, the gears are not matching what gear the TCU shows it is in. I have to ohm out each one, and see if there is a problem and where. This could be a delay which could keep me from making it to the FL2K10 ![Sad](https://www.clublexus.com/forums/images/smilies/sad.gif)

We"ll see.

Hip, Hip, Hooray!! The transmission wiring to the PCS TCU is completed, and fixed. I need to trace a vacuum leak, and correct that, and then I should be ready to tune.I would say within the next couple of weeks! It is looking good, and getting real close.
Thanks to Dan Osypian for being right there in the trenches with me and helping me to get this right, and completed!! Also, thanks to the phenomenal customer support from Dan at PCS....Second to none! First rate organization. Thanks also to Dr. Tweak!!

Gang, I traced the vacuum leak tonight, and ran a temporary test to determine if it was indeed the culprit, and it was. The SM4 has its own built in MAP sensor, and it strongly recommends the hose from the sensor on the SM4 be dedicated only to the SM4, and connected to the intake. It was not hooked up that way. The Defi Boost gauge and the Greddy Prefec B were T connected to the same hose....an absolute problem set up like this. The reason I knew I had a vacuum leak was that my pressure readings never changed when I started and ran the car....It stayed at 100 kpa. So, I ran a temporary test hose from the SM4 to the intake, then plugged the hose to the gauge so it would not leak either, and then started the car. Sure enough, the kpa dropped down to 58-60 while the engine was running. So, that was the problem. Idle is still rich at 11.4, but I am in contact with Ian Hamwood from Autronic, and Enzo from New York. Phenomenal support from these guys!! We will get this adjusted more when we tune. Motor sounds much, much better now, and the throttle response is instant.
Transnission shifts in all gears. getting closer....![Woohoo](https://www.clublexus.com/forums/images/smilies/woohoo.gif)
I have more of the engine put together, so I thought I would post a few pics of the engine bay, as this is a little closer to what it will look like when I have it completed. I also took a few pics of the iForged wheel again. a little better lighting.

My SM4 stand alone is currently in New York at Enzo Racing being reflashed for all the latest updates, software and features from Autronic. Enzo has also been an Autronic Dealer for the last 10 years or so, and knows the unit like the back of his hand. he loves it, and highly recommends it for many reasons. He also tunes and bubilds custom fabricated performance set ups. Anyway, he is tweaking my SM4, and after this I will have the all important speed sensor based traction control, like what Race Logic builds and sells for about $1400. I sure saved a ton of money on this one!!![Woohoo](https://www.clublexus.com/forums/images/smilies/woohoo.gif)
Here are a few pics of my headlights which are near completion. These are only mocked up and held in place with some double-sided masking tape, so do not be concerned about the unevenness of the LED's. Everything will be in it's place upon completion.
