Just wanted to keep track of things and I am unlikely to do so elsewhere.

I got my boost error completely under control. My WOT boost error, once the turbo hits full pressure, is within 1/4-1/2 PSI +/-. I cut the burst and continuous dynamics down just the slightest bit more to fine tune the target boost. I'm not sure if I can dial in the boost any further, but I will be doing many more tuning pulls this weekend.

The dropping IAM problem was totally solved with the full tank of 93. I have seen a max KC of 8 which coincides with full advance of ignition timing. I haven't found a table that mentions this KC value so I assume it is hardcoded but am still looking. I am also working on finding out how much timing is too much timing. Currently I am running 8.09 advance, and the increase table is set at .35. I am going to drop the increase table number and raise it in very small increments.

I am not sure if it is a problem but the Initial IAM on the map I got is set at 16. This is fine if everything is running good and you know it, but I don't like the ECU allowing max values to run after I make changes so I set the initial to 12 and allow the ECU to regain the 16. This way I know the car is actually happy.

I'm currently in the process of looking at a few other maps I have collected and comparing them to decide on the best timing maps. This is probably going to take me a while.

On a side note, I did have a guy with a Turbo DET20 240 ask about my car. He wanted to know what I had done and how much I put into it. After he found that I had put less than 800.00 in power mods on it and I had tuned it myself, he seemed kinda pissed, considering how much he spent on the JDM motor, and that he had a much slower car.

Again, I am still amazed at the abject lack of people who actively are tuning their cars and posting into the EM forums, especially considering the relatively inexpensive open source methods available. I was hoping the EM forums would be a trove of really experienced OS tuners who say around and schemed up new ideas and plans for innovative tuning and whatnot, but I think Halo 3 is taking up too much of peoples time.

I think I'll just stay in the garage.
