| The Next Petter Solberg | Hi Brandon. The MAP sensor install is very easy. Just a matter of stripping a few wires and soldering on the new clip. I didn't cut off the stock clip because I didn't know if I was going to keep the new MAP sensor. I'll try and post a picture tonight. I've got a busy week, so I apologize now if it takes a little while for me to do. As I'm sure you know, the new sensor does require a change to the ECU in order for it to read properly. So definitely don't go into boost after the change until the ECU changes have been made. The welding is going wel. Unfortunately, I don't have enough time to practice every day. Or even every week now. I guess I was lucky that I was waiting a long time for car parts when I first got the welder. It gave me time to learn to weld. I feel competent enough now to do most anything I need to do. Not a pro by any means, but (now that I pay attention to welds I see everywhere) I have seen much worse than my welds on things that are sold. I still wouldn't trust myself on suspensions parts, but everything else I'll do. When I'm taking pictures later, I'll take a closer shot of the last aluminum weld I did.

Dont worry about hurrying up I am have been working overtime for the last 3 months everyday. I have had one full weekend off and one sunday off in three months so I feel you on the no time part. Just got through working 8 12hr days in a row and still have about another 10 to go then overtime should stop. Brandon | |

| The Next Petter Solberg | Cool. Might as well make the parts you can. Nothing like a true custom. If I haven't gotten you the info you need by the time you need it, shoot me a note and I'll get to it right then. |

| The Next Petter Solberg | Well... I just got back from my first drive using Freon's speed density ECU code. My fueling is really, really off. But... It drove. And thanks to some help from the ECU's closed loop code, I succeeded in getting to the gas station and back. |

| The Next Petter Solberg | I now have two different thermistors to play with. I disconnected the MAF sensor and then plugged one of the thermistors into the MAF connector to see what would happen. Simply amazing. I got a reading of 84F via the OBDII port for IAT. Then I plugged the MAF back in (removing the thermistor) and checked again. 86F for IAT. Off by only two degrees and I haven't even scaled the sensor table yet. I am guessing it might be off by more as we move up and down the temperature range. But, golly that's ok cause we can change the scaling table. Piece of cake. I still haven't quite decided how I'm going to install this, or even which of the two sensors I'll ultimately end up using. The first install will likely be a bit hackish. I will keep y'all informed on the progress of course (when there is progress). |

| The Next Petter Solberg | Some notes as I start tuning with the speed density patch... I have my idle pretty stable now. I do have a bit of a fuel bounce as I let the clutch back out at low loads in some cases. I haven't tracked down the exact cause, and it isn't too bad. But it does cause an occassional, mild stutter. Probably a combination of my map needing some minor adjustments, tip-in values, closed-loop fueling, etc. I've done some WOT runs at wastegate pressure only (so I could dial in a relatively constant boost without having to fidle with WDC tables). Plus, it is a nice pressure level, being at about half the positive pressure in the VE table's axis. After only a few runs, I can say my AFR is certainly no less stable than before. I'd actually probably say it is MORE stable and predictable than when I had the MAF. One benefit of this, and possibly a major aid in the fueling stability, is that there was always a bit of an issue with the MAF sensor being "so far" away from the throttle body when using a FMIC. That is the generally assumed cause of the rich spike that occurs as boost peaks during a WOT run with a FMIC. With the MAP sensor being in the manifold, there is no similar delay. |

| The Next Petter Solberg | It is attached to a knock sensor on the engine block. Theoretically, it will flash when detonation occurs. Here's a link to the one I have. The page also has a bit more info on what they are, what they do, and why the can be useful. Turbo XS KnockLite |
