Well, I also posted this on CF, but I don't really expect too many responses there since it doesn't involve an airfoil or floormats.
Just as the title suggests, that is my question. I plan on doing some mild upgrades, and want to know at what point the factory computer is limited in its adjustments and a chip is required? My current plans are mildly ported/siamesed stock plenum, slp runners, siamesed stock intake. I also have front cats deleted, magnaflow catback. I will also be replacing my injectors and am debating between 22 and 24 lbs from FIC. At a cost of $200 for a chip, I'm also considering getting the OBD cable myself w/tuner cat and the ostrich emulator. It wouldn't cost that much more, and if I decide to do heads/cam in the future I could tune myself. Comments? Matthew |

Whenever mods are installed that are going to require you to add additional fuel.
Or install a modification that require different parameters to run than stock, IE larger injectors. Thats the simple answer anyway |

I would say it depends on MAF vs. MAP as well. MAF has the advantage of more directly measuring airflow.

Well, I understand that when you make big mods, a chip is required (ie heads/cam). But the stock computer is capable of making adjustments to a certain point, I just don't know what that point is. It is very versatile in itself.
Just making a simple mod doesn't require a chip or a retune. My ultimate question is at what point is it required? Anyone have hard #s? Thanks again, Matthew BTW, my 89 is a MAF  |

Required? Maybe when the car doesn't idle?
You can make gains from a tune no matter how many mods you have. Some choose to hillbilly it with 100hp worth of mods and lose 40% of it because of a poor tune or stock tune, others will retune it after changing one piece and pick up 20hp. I don't think you're going to find a cut off point. I'd say its required whenever the cost/benefit of the tune is better than the cost/benefit of throwing more parts on a stock tune. |

Good point. I am considering the ostrich emulator by Moates ($175). That was I could make real time changes to the car with a laptop. Anyone have any experience with it? I have zero experience when it comes to tuning, but I'm sure I could pick it up quick. The ostrich system uses Tuner Cat software, which I understand is pretty good. Thoughts? Matthew |

tuning is quite hard, not something I would do myself, or send to someone without a LOT of experience.
"My current plans are mildly ported/siamesed stock plenum, slp runners, siamesed stock intake. I also have front cats deleted, magnaflow catback. I will also be replacing my injectors and am debating between 22 and 24 lbs from FIC." If you go with the 22's, a tune will not be needed for those mods. Would you see gains from a tune? Yes, you will see gains from a tune on a stock car. Heads/cam/24's you need to tune. |

You can use tunercat or tunerpro with the ostrich. I go back and forth. I like tunercat a little better I think. Years ago it would take me forever to change things. Burn a chip, run outside, scan it, run inside, burn a chip. Now I can make a ton of changes from inside the car. Go for a drive. Pull over, fix AE or whatever is off. etc. You'll need an Ostrich, A G1 adapter, a laptop, software, and an ALDL cable. My aldl is hard wires to the harness and I have a serial cable hidden under the dash. My ostrich is USB and that cable is hidden as well. -- Joe |
