w00t! My GSL-SE AutoXer moves again!
After spinning the rear bearing my last engine with my v1.01 and really early firmware, my GSL-SE moves again! I sourced an engine from the SA22C list, got that installed with FrankenRex's assistance (supervision and superior wrench turning skills) and loaded the latest firmware into my v1.01 + flyback circuit equiped 'squirt. I got it tuned to zero load pretty well with the assistance of my wideband and drove it around the block just a few moments ago. Now I need to find a cheap (free?) dyno somewhere so I can finish out the map. Anyone with a dyno in the D/FW area that is willing to sponsor my 4 time regional championship car is welcome to come calling! 
It's time to kick it up another level and start going for some serious trophy collecting.

Hmmm, where I've been
Let's see. In 2001 I got everything rolling with getting married. My wife got laid off but it was expected and worked out pretty darn well. In 2002 I bought a car, bought a house and had a kid. The car was running like pooh mostly because I was too cheap(broke?) to buy the correct tool. I ran most of another season in 2003 and the local divisional in 2004 and 2005. In 2004 it was in a BMod Datsun SR311 and this year in Charles Wright's red, white and blue 79 CSP RX-7. This car was one I'd admired for a while having previously been Wendell Karr-Ake's car. If you've looked through the customer gallery at G-force Engineering you've probably seen it. In December of 2004 I was laid off and took my six months salary plus 160 hours of vacation and paid off our credit cards, started flying and started working on my GSL-SE again. This time I bought the right tool.
It was long about this time that I noticed my car was starting to need more and more fuel just to keep idling. Something is definately amiss here. I eliminated everything external to the engine except the Megasquirt. After a while I started to notice a whine coming from the engine and shut it down, never to be run again. Those three or four times to 10,500 were just a few too many and it spun the bearing on the rear rotor. The bearing had moved about 5mm and was pushing the rotor into the center iron destroying both in the process. (Un)fortunately shortly after this I got re-employed. Now I'm back to having zero time plus a family.
I sourced a couple of engines, one running engine, some parts engines. I got the engine into the car with moral support, supervision and help from Kevin Wright. With the MSnS-Extra code loaded into my v1.01 'squirt it's back to square one. This time with an Innovative LM-1. Once I got it running the first thing I played with was the rev limiter. Man that's cool! I wish the ice would have stuck around here a little longer so I could have played with the traction control code as well but that will have to wait.
12x12 tables are cool. AFR target tables are wonderful. The rev limiter will save my engines from me! Now I can finally teach my wife to bury the throttle until the rev limiter kicks in and just keep pushing the rev limiter up until it's around 8,000 to 8,500. This engine will also eventually get a 2nd gen CAS and then tuning will begin all over again.
This effort won't be just for one car either. I have a 84 GSL that's waiting to come home so I can start working on it. The current plan is to get a 12AT and make it a street machine and daily driver. I've always thought it would be cool to have one so now's my chance. After that engine is gone or I get the urge for more power it will become a 13BT or 13B-REW depending on how much money I have and how good my fabrication skills are at the time.
