mpi tuner?

[MPNick]

How many wires overall have to be cut or spliced?
Do any have to be run into or from the engine bay?
Are most wires found at the PCM?

Around 15 wires total. The only wire that may need to be run into the engine bay is if you are running extra injectors. All but one wire is at the PCM, The fuel pump wire is at the front of the shifter.

Thanks again

Have you tested this on the Protege? How do you know for sure?

We only tested 550cc units. They were real good new type injectors. I would never use any old type injector on a modern car.

Thanks again

There are 13 steps in the instructions for wiring the turbo module and mpi tuner.

No wires need to be run through the firewall unless you go with the extra injector setup.

All of the wires can found near the PCM, again unless you have the extra injector setup.


1sty: You should consider deleting your first post now that Nick has cleared up some of the misconceptions. When someone reads this thread for the first time, they might be misguided by some of the info in that post. As Nick said, none of that is true... for the most part. Not trying to be a dick at all, just trying to make things less confusing about the capabilities of the mpi unit.

More details about the installation can be found in this thread:

wtf is a "new type injector" or an "old type injector"?

 

[jred321]

why wouldn't he be able to pass inspection?

And you couldn't pass an e-test or what?

What were the specific emissions outputs through the tail pipe and what kind of test was it? Rolling dyno style or what?

like I mentioned before I'm not worried about emissions where I live so that's not important. As long as the MPI tuner can control my 460cc's then that's all I need. I'm assuming when you say old type injector you mean a peak and hold (low impedance) and a new type injector being a saturated (high impedance)?

Do you have any particular reason you want to go with the 460's other than you have them already?

 

[ARunto]

well i already have the injectors and i'd rather do bigger injector setup than adding additional injectors.

 

[1FASTMSP]

do we have low or high impedence?

 

[orangezoom]

High

If you have injector already then buy my injector boss and rail kit and run the extra injectors. You will have a better running car. Bigger injectors do not run great in our cars for everyday street use. Some posted dyno sheets that other day. They had a E-something and big injectors. The dyno sheet was not that good at all. .8 bar of boost and only around 200whp. The fuel curve was not any better the the extra injectors, in fact the extra injector curves are better.

Why though? Extra injectors are better in my mind mainly because you have stock control under cruise and idle, but have extra fuel when you need it. Bigger injectors in place of the stockers are well known for being hard to tune, especially at idle.

Just a thought.

good help

MPNick? hello?

MPNick? hello?

Sorry I did not see this.

Injectors have come a long way over the years. The lastest type by Bosch and Denso are the best I have ever seen. They spray fuel from the tip of the injector like a fine mist. Better fuel mix, better power and better to tune. I have replace injectors in older cars with these new styles. The cars run better and they make more overall power. Just because you do not have to take your car to inspection does not mean anything. If your car runs like a pig you are giving up power and also the life of the engine.

The Proteges have one of the lastest and greatest injectors and PCM that the OEMs have ever used. Why give it up and run old style injectors instead of keeping the stock units and add extra ones? As far as I have seen on this forum. The strongest Protege makes 328whp. It has the MPI Tuner, stock injectors in the intake and two extra injector in the throttle body.

Thanks again

[jred321]

are you refering to saturated v. peak/hold or ball/disc vs. pintle? "old" vs. "new" means nothing

 

[jred321]

It will control them. The problem is I have yet to see a big injector setup run 100% at idle. Plus you will not pass and inspection testing any longer. Also what type of injector are they. You should be looking at new type injectors. Most older type injectors are junk.

Thanks again

from this, why wouldn't he be able to pass inspection?

 

[yashart_mp3]

how come everyone keeps skipping over the question?!!? HOW COME THE MPI ON A MSP WILL NOT PASS INSPECTION????
