Ok so did a little research and it looks like I need to set
my codemask to $AA to disable the checksum checking during emulation. It seems that by not disabling the checksum, it could be putting the ECM into limp home mode which is why the fan turns on with the key in the on position (always happens AFTER the fuel pump primes too). Apparently this can also prevent data from coming through the ALDL port. Also, my fuel injectors are supposed to be ready to pick up tomorrow, so I'll be grabbing them as well. Hopefully all goes well. |

Got the engine running today and took the car for a couple
spins around the block. Pics and vid to come soon! |

So injectors were the main problem, also my chip adapter
wasn't pushed in all the way... . Anyways, after the cleaned injectors were installed and I loaded a 3.1L tune into the emulator, it started up first try! After that we took the car off jack stands and took it for a spin around the block a few times. Feels so good to finally drive it! And here's the video: LX9 Start-up |

Congrats!
Sounds good with no exhaust! Nice vid, especially like the 'he's got no liscence on that thing' at the end. Classic. Chay |

Exhuast will be done on Monday or Tuesday and I'm gonna put
plates on it soon after and really begin to dial in the tune. I decided to get a y-pipe made at Mill Bay Muffler to keep things fairly inexpensive (using the stock muffler and tips) and they're gonna weld up my cradle nut and battery tray as well. If I want a better exhaust later I can always upgrade to a better stock-style muffler. How much longer till your turbo build is done Chay? |

It'll be a while yet. I'm working on the exhaust right now...lots of tricky fab work because the 2.5" mian exhuast and 2' wastegate tubing has to come together at some strange angle. You have at least a couple of weeks, probably more like a month...no rush!

Put plates on the car yesterday after getting the exhaust done and having a battery tray made. The car is much quiter now but still sounds really good IMO. The tune is fairly close now at least with part throttle driving; just running a little on the rich side now. So far no problems with knock retard so I might play a little with timing advance as well. I'll probably get a video of the final exhaust sound later.

Thanks! Gas mileage doesn't seem to be too terrible right now so that's a good sign. I was worried at first about how bad the 4 speed manual would be. I think it probably helps that the torque peak of this engine is relatively high compared to the 2.8 (4800 rpm IIRC), so it should in theory be more efficient at mid-high rpms. Once I enable lean highway cruising in the tune it should get even better. Only issue right now is that it's been stalling once warmed up but I think I figured that out so I'll find out later today. I think it tries to go into single fire mode when idling and that's causing the stalling. Disabling single fire mode will hopefully solve the problem. Oh and since I still don't have an upper dog-bone mount I'm driving pretty conservatively right now. Hopefully I'll be addressing that on Monday. |

Disabling single-fire in the tune made the idle problem go
away. VE maps are also just about done. Not too much left! |

Tuning is just about done. I'll probably set up a nAst1
tune and a regular A1 tune just because the nAst1 has a few glitches here and there. It's great for tuning with though. This engine is just begging for a 5 speed swap! Maybe I'll get around to that by late summertime. |

So tuning is pretty much finished. Also had to replace and require my
alternator recently. And I now have a dog bone mount. I'm planning on going to the 1/8 mile drags at western speedway tomorrow so we'll see how that works out. |

Had some good fun at the SISLA event today. Best time
ended up being a 6.489 @ 62.27 MPH. Didn't break any transmission mounts and did some light burnouts. Wow it's really easy to get a good launch with these cars. With some better tires I could probably shave another 1/10 of a second away. I thought it was pretty awesome beating most of the V8s in street class and also having one of the most quiet cars there. It's a 384-foot track. On the other hand a brand new Shelby GT500 crashed on its first run... And I snapped a pic of my dog-bone mount and the car with the stock wheels now painted satin black: |

Your times seem really odd to me. I went back and checked some of my old time slips from when I was running a strung out V6 (2.8 with mods) My best 1/8 mile with 9.4 at 75mph. (3 seconds slower but 10mph faster) which does not make any sense to me? I was racing against a Turbo Miata at the time in my now deceased 85GT with a 4spd trans. I was car 3641 with a 14.6 quarter mile. Scan of my slip is here, http://www.captfiero.com/missiontime.JPG

Yes it's not an 1/8 mile track it's a 384 foot track.
Sorry for the confusion. |

To compare, my best 330-foot time was 5.711 |

To get a 5.7 330 you were cooking along really well. I am impressed.

Looks like good work on a budget. Don't think I could get results like that for what you have spent. Let me know when you are ready to do your 5 speed swap. I have a 282 from a cavalier that I spit the case on to replace the speedomiter drive gear and left sitting in the garage till I moved back to the Island. It is sitting in the basement looking for someone finish putting it back together. Would be interested in getting your 4 speed shifter for my current project which is an f40 6 speed swap. PM me the next time you plan to come through Mill Bay and have the time for coffee.
