MPI Tuner Anyone?

[505zoom]

Ordered mine today, without injectors. I will be adding the injectors later on, probably about a month or so after I get the unit up and running. I also have the AEM UEGO, and an EGT gauge coming to help with the tuning. I'm really looking forward to this, and I will post about how the unit works on the speed for all you guys that want to see proof.

Congrats..be sure to take your time cutting wires and such..most poblems associated with standalones and piggy's turn out to be improper wiring by the installer!

(werd) Thanks for the advice. My good friend's brother is very skilled with automotive wiring, and he will be doing all the soldering for me. He soldered my TT wires for me, and it looked better than all the factory wiring. I will take my time with it though, don't want to mess this up.

Anybody know where I can find a diagram for the PCM wires/pins?

I believe he includes with every piggy he ships!

They are what? They are not different then any other injector used on any other 2.0 Protege. I do not what size the 2.0 Protege has for sure but they are not any bigger.


Thanks again

he was responing to my post.. agreeing that they are the same as a regular protege.

Excellent (friday)

On the two MSP that I had my hands in they were the same as the stock Protege. I cannot speak for Turboge was looking at.


Thanks again

Ok, myabe I'm worng then...

Our warranty is for one year. After the unit is tested by us and if we find it defective, we will replace our repair at no cost to the customer.

How does something that does not exsit in the real world look good to you? As of last week when I called AEM they told me flat out that they are not building any PnP unit for the Mazda. What do you think the cost would be to get a AEM unit, take it apart, then have a EEV-V male and female connector plug molded, then have all of the wires [105] installed and tested. I would think that the cost would be in the thousands of dollars and I do not think that a one man show can absorb that cost. Keep in mind that even if AEM does down the road build a system for Ford EEC-V, it is not the same set up as the one used in the Mazda. Plus you still have a system that is not legal. AEM builds these systems to be a stand alone only system.

The game is controlling the spark and fuel. We get the job done with two hours of work to install the system at a cost for $675.00, add $345.00 for the extra injectors. If this is not your way of tuning then spend $1,500.00 for a system, plus $400.00 for injectors, thousand of dollars for dyno tuning and never take you car to inspection. I still think that you will have problems with fuel wash with the big injectors. Someone posted about a month ago that he lost compression from running rich with a parallel system and big injectors. People are always talking about cold starting problems with big injectors and after market sysetms, even Terry from Spool has posted that they had starting problems in the cold.

How does your car start and idle now? That is the same way it will start and idle with our MPI Tuner. Because we are not taking the tens of millions of dollars of testing and tuning that Mazda did in RD and throw it out the window. We only make our changes when we are in boost. Why change the whole computer if you are only in boost less then 10% of the time you are driving the car? The OEM system build today are more powerful and any aftermarket system you can ever buy. Learn to control it and you have the best of both worlds.


Thanks again

Everything you say has been covered in the thread regarding the AEM. It's already been said by the person bringing it out that AEM is not going to make, is not making, etc...

It's already been covered that it can run has a parallel unit, thus getting by the stand alone issue.

And you seem to tbe the only one that says larger injectors are bad. Keith has stated numerous times he has had no problems on the thousands of Miatas running around with larger injectors, and all of them pass emissions...

With the proper tuning you will not have problems, do you agree with that?

I think the disagreement is in how to get to the "proper tuning" to do what the customer wants.

Yes, i know this, its been covered 23048320483948309482390 times now, they are the same 280cc green and purple injectors that all other proteges run.

No I do not agree with being able to run in paralle. I do not think you can do a PnP in parallel.

I am not saying they are bad. I am saying that stock injectors used along with extra injectors are better way to go. When someone has 550cc on a Protege and they can pass the the IM240 and the BAR 90 without having any problems I will agree.


Thanks again

I think the reason Nick doesn't suggest you run larger injectors is he cannot control them at idle, and it kills your idle because of that. Perfworks and Wagner suggest bigger injectors because they can properly control them at all speeds.

Extra Injectors in the intake system is really on a band aid fix to lacking the control to just run bigger injectors. You can only run so much boost on injectors in the intake before they start killing your engine, distribution of that fuel isn't guaranteed to hit all cylinders, and could end up throwin a rod. Corky Bell would agree with me on this one.

I only say this, because I plan on running 18 PSI, the only way to do that is with the AEM PnP or Motech, and running bigger injectors.

 

[igdrasil]

I dont know why you say this, Wagner has done the additional injectors setup.

Hiboost claims he control 440cc injectors with the F10, ask their customers, they have really bad cold starts and idle.

I remember one guy here saying he had to crank the car 10 times in order to make it start with the haltech F10 and 440cc, that supposedly has control on them.

I dont have that much experience, but I can say, you have to play with, fuel pressure along with injector control, some R&D in your setup and you will have a satisfactory, not perfect, idle and fuel control.

This is getting very old. If you think that you will have great luck with the PnP that never will be then go for it. As for the Motech if you think it is money well spent good for you. Big injectors on street cars are a bad idea. We have already used 550CC on an MSP. Removing the stock OEM computer is also a step back in time. Not one system on the market today is as good as any OEM system.

Corky Bell is a good man, I have over the years talked to him a few times over the phone. He has his way of doing things. Not all of them are right. He is also the man who made the FMU. I know of no one who as ever had the FMU work right on their car. It has always been hit and mis.

As for the extra injector setup. You people have been shown cars from the OEM that have run the extra injectors. I have shown you very high power street cars running the extra injectors, one is making over 1,000 hp to the wheels. If you have problems with seeing proof that they work and feel better with big injectors and a phantom system that may or may not ever work go for it. Remember the source that you are basing your info from. It has been all over the map on what is the best thing to use. One day it is the pigyback and extra injectors. Another day it was the FAST system. Now it is the AEM. What will it been next month?

If you are planning on running 18psi you should be around 400 hp. That is one fast car. If I were you I would not go with the AEM or the Motech. I would ask Perfworks to set you up with the same system that he used on the 400 hp Mazda he built back about a year ago. That Infamous 400 hp Protege was all the talk on the other Mazda forum.

I also know that Pirana's car started fine every time. Just turned the key to the on position for about 4-5 seconds before cranking the engine. He ran rich as hell though. I could smell the "rotten eggs" everytime I was driving behind him (very often).

What do you think is going on inside the engine when you run that rich? The intake valve guides are being worn out, the rings and cylinder wall are being washed out also.


Thanks again

[LinuxRacr]

Yup, with the stock injectors. I think the MAP sensor may have had a part in that...

 

[PaulMP3]

Not sure about your sensor. How many wires does it have. Most are four wire sensors and these are not Wide bands.


Thanks again


Later.........Nick

i just checked... mine has 5 wires(nana)

 

[LinuxRacr]

Yeah, my techedge is the 5-wire NTK L1H1 sensor. The funny thing is that my J&S Safeguard 52mm gauge can utilize the 4-wire Bosch LSM-11 for A/F monitoring:

It is callibrated for it. Can you guess what Perfect Power units are callibrated for? (LSM-11)

 

[LinuxRacr]

I have been noticing that folks are not really aware that this piggyback is viable for N/A applications as well.

How cold does it get in the winter snow belt that you live in? I am sure that people who live in cold parts of the contry have starting problems.
