The first step is to build a data logger. You can buy the cable ( http://www.aldlcable.com/) or build it for $7. Super easy:  Here is the circuit:  Ready to solder:  All done up with power and serial port.  Instructions: http://www.aldlcable.com/sc/pages.asp?pageid=24In the truck:  The connection to your vehicle.  Couple of screen shots from the software:   Reviewing the data logs in slow motion I can see exactly what to changes throughout the different rpm and load conditions to make the thing scream. I was always a carburetor guy, but TBI is da chit!!! Very sweet software, screw those handheld scanners!! http://www.tunerpro.net/In the next post I will describe some of the changes I am going to make to the chip and how to do it, and the improvements.... or if it gets worse. |

Are you positive about the ECM in your rig? Some just have an ODB2 plug with older computer behind it. http://www.cruzers.com/~ludis/c3xref.html |

What? was the parking ticket for?
I was working down there at Coral Way & Ponce for three month...I got a few parking tickets throughout the project with 15 minutes = $0.25. I'm sure you know the parking situation there. The client paid all eight of the $18 dollar tickets I accumulated so I am happy. The crash was separate. The officer failed to yield my right of way and tagged my bumper on the road. |

If you can short terminals in the connector and read codes, you can do this my friend! I have a few ancient eprom programmers, but decided to spring for this one. I really like it so far for $30. http://cgi.ebay.com/PCB5-0-Lite-Willem-EPROM-programmer-BIOS-PIC-from-USA_W0QQitemZ310055784311QQihZ021QQcategoryZ4661QQssPageNameZWDVWQQrdZ1QQcmdZViewItemLOL, tonight I used christmas tree ornament hangers to save $10 on the moates memcal reader adaptor.  Got em in there easy I must say!  Looks like it belongs!  Haha, I am way too cheap to buy a parallel cable so I plugged the eprom programmer into the back of my desktop.  I have noticed while data logging my motor has the weirdest timing advance going on, now I see why. Check this BS spark table in my stock PROM out!!!!!  Here we see how I am going to erase my memcal with the UV sterilizer on my fishtank...haha, I have another germicidal lamp in a tool box I really use.  That is how I became a tuner for $35. |

Wow, simply amazing what a few numbers can do in the ECU. I have to admit I have killed my mileage for now BUT the freakin truck feels like it picked up about 100 HP. I can literally bake my tires from a dead stop full of tools. Upping the shift points is a bad idea for a street truck...lol, sure was fun in the rain today though. Oh well, tomorrow I will try out some programming that is guaranteed to make the thing feel like a 4 banger. Hopefully the mileage will match.  I just have to thank Chevy1500z71 for leading me to this! Sure wish I had a dyno.... |

Sure wish I had a dyno.... a dyno shop will charge you about 100$ for an hour, so when you think your close to the perfect tube, pay for an hour on the dyno and get it dialed in 100$ with a wideband 02 sensor and all. everyone always gets there stuff tuned before me! i keep saying im going to tune my truck but i just cant get the extra money. |

I'm think I'm going to go with the LM-1 wideband adaptor from Moates. http://www.moates.net/product_info.php?cPath=48&products_id=91 I can get the 5 wire it takes for $50. I'll probably grab the Ostrich 2.0 emulator first though...no way I would pay to put this stocker on a dyno...well maybe to win a bet or something... |
