wouldn't a MAP conversion also allow you to turbo the 3sfe safely...or does the MAP conversion not allow you to change the TPS to allow for more than 3 positions(even if you have to upgrade the TPS)? It would be nice if we could get something to allow us to turbo our 3sfe's without spending an arm and a leg swapping in a 3sgte. the map doesnt replace the tps....only replaces the afm |

the map doesnt replace the tps....only replaces the afm well, i thought maybe it was a hack to the fuel management system, is it not? or is was that just what a standalone is supposed to do? And i figured if you're hacking the fuel management(air fuel mixture) don't you grab data from the TPS as well as a few other sensors? And if you're grabbing data from the TPS you could replace the TPS with a more accurate one(since the data would be going to the mod instead of the ECU, correct?) that could fix the problem of the TPS not being accurate enough for a turbo. I probably don't know what the hell I'm talking bout though, lol. but i'm guessing this MAP conversion, from what you're telling me is just a replacement Air Flow Meter which plugs into the original plug for the MAF/MAP/whatever it is....right? |

I'm not really sure. the tps is adjustable tho I know that much. I havent really messed with the tps much.

hes refering to the gt tps, its gonna be different on a gt-s, we have a different intake all togher. as far as turboing a 3sfe, its a waste if you ask me, you'll end up fabricating so much stuff its gonna be the same if not more expensive as the 3sgte swap, and will have much less power.

3sfes can't be turboed because the blocks suck and can't hold boost. It has virtually nothing to do with the air counting.  |

The block is the same as the ST165 3S-GTE, and the only difference that it has between the ST185 3S-GTE is the oil squirters. Yeah, the pistons suck and the crank is weaker, but the blocks are the same.  No, the TPS is NOT adjustable. Trust me, if it was, I'd be happy (More gas milage all round, sounds good to me.). Other than that, the 3S-FE has a notoriously weak HG that will blow under the slightest influence of boost, not to mention the weak pistons. True, converting to a MAP setup would be easier if you were to use stand alone engine managment, or some sort of piggy back TPS system, but then you would have to deal with the other problems that the system has. In summary, just not worth it. /back On Topic  |

Uh, I have no idea what in the hell is, but what I'm putting together will look nothing even remotely like that... You get to ditch the AFM entirely, and just do straight intake plop into your manifold.

I'll have to find the link on how to do it....anyways I'm sure the tps on the 3sge is. i know it is on a late model 22r and many other toyota's |

No matter what you do to it, it will still only register "idle" and "wot" settings.. and nothing more. I belive if you had a better TPS and a metal headgasket, you could safely run 6-7lbs of boost on a 3sfe. Unfortunately, that's not a reality. |

It's also higher compression, and who knows if the FE ECU has maps for afm readings up that high...? Can the FE AFM even count that high?

prolly just sees it as wot and doesnt send a reading.

Ok, I was wrong. Can someone tell me in what way's it IS adjustable? The 3S-FE at WOT, from what I understand, generally goes in to a dump mode and puts injector cycles to 100% and dumps fuel into the engine. |

I'll have to dig up a link for the tps adjustment....found it if you screw up your tps dont blame me www.speedtoys.com/~oldmage/misc/tps.zip |
