Ok so I need to know for my engine management what to use. I wanna daily drive it and it needs to pass emissions. What's the best way to do this?
 
With 340 whp? Don't lol

But depends on how strict your emission laws are, do you have a cat? What are you tuning with now?
 
Well there was a split second. All they do is plug into the OBD port. And check for codes.
 
Unichip plugs into the obd port, split second splices into factory harness and does not just read codes, it will work up to 14 psi past that you will need to upgrade to the map setup.

If you're not tuning it with anything do not drive it.

You don't want a built protege as a daily, its not exactly smart to do. Or Atleast I wouldn't do it or recommend it
 
I'm not gunna beat on it. I ordered my rods and pistions today I'm having my crank checked to see if its good.
 
Unichip does not hook up via ODB. It simply plugs into the factory ECU harness as a jumper.

340whp is not going to be do-able with a stand alone, and passing emissions. If there is a Unichip tuner in your area that may be a viable option, though, as you can install and emove the unichip quickly, and easily.

What are your mods for 340whp? Seems a little ambitious, and if you're asking these questions, out of your realm of knowledge. Just cause you forge a motor doesn't mean you can make that much.
 
When I say 340 I just want a daily driver with 300 hp. I am working with other people on my motor. I just wanted to see what you guys did to pass emissions
 
just get a stock MSP to run the test and pay the guy $100 to type your vin in the computer.

its pretty hard for them to turn down $100.
 
Quite honestly, I don't think you're gonna get the answer you're looking for from anyone on here because I don't think anyone has succeeded at what you are trying to do. Very few members have gone over 300 HP and the few that have are likely in emission-free states.
 
Find someone that makes inspection stickers. I've known alot of people to do that, as long as its a good printer no cop would know the difference. I mean seriously has anybody ever had a cop look at an inspection sticker other than seeing when it expires? You could also "steal" your friends once a year, just use a blow dryer to heat the glue up so that you don't rip it.

There are many shady ways to get away with it. You can always say you bought the car like that. Of course I'm not advising you to do these or lie to the state during emission tests, just stating options
 
all of you are reading his post wrong as far as emissions go. Someone stated something about how strict his emissions laws are. OP is saying all they do for emissions is plug into the obd port and check for codes. He's not saying the EMS plugs into the port. Also, if you want to retain emissions with a standalone, talk to Sam at Crossover Auto and order a Haltech Sprint 500 with the prewired harness. It is wired as a parallel setup. Stock ECU retains control of other stuff while the Haltech controls all tuning parameters and CEL still works. As a matter of fact, when I installed my Sprint 500, my CEL come on for crank and cam sensors. But it was due to the map I was starting with. When it comes to standalones, you don't NEED to wire everything up. You don't have to control every single part of the car. Parallel setup is the only way to pass emissions. If you want to DD a 340hp protege, by all means, do it. Several people here have done it. Some still are. The only issue after you find the right turbo to use will be trying to keep your transmission together. The stock gearset won't cut it and people have even shredded PAR straight cut gears. It is not impossible to drive a 300+hp protege. However, once you get into that range, you may want to look into getting a beater to drive around because in the end...it's a protege and something may break. When you start talking about making 300+, you are always going to get mixed comments on what to do. Im actually aiming for the same power, if not more. But before I do, I'll have another DD. I have another car already, but I share it with my wife. So, I'll be getting a second car specifically for when the msp is down.

Who has shredded a par straight cut gear set?

Never heard of a PAR set coming apart.

Hey OP..

Look at www.mp5t.com

Just for a start..

Transmission $7K

a few people here. I can't remember their names. I believe they shredded a straight cut 3rd. The PAR set has a more strict fluid change interval I believe. But even with the straight cut gears, as far as I know, there is still a problem with the shafts shifting under high load. PAR has the reinforcement cups but it isn't a 100% fix.
