ECU tuning question

I love my MPI and I also suggest buying the J&S Ultra-Safeguard.
With these two items you can pull all the extra HP out of the car you can and also protect the car from blowing it's engine....
No matter what EMS option you go with you should still buy the J&S becuase no EMS can do what it can do which is make the car faster and protect it from blowing !!!

Not exactly good practice to break the rules and try to hide it. I also forgot about the MegaSquirt. You can control fuel and timing with it and would probably be a fairly good option. A friend of mine was wiring one up for his Grand National and was testing it with his turbo Integra. Not sure how it's worked out so far, but I've heard good things about the system.SirJaime said:
You basic options for fuel and timing are:
-MPI Tuner
-MegaSquirt
-Emanage if you can get the timing control to work. I know they fry coils on DSM's and I'm not sure if anyone's been playing with timing on the MSP's that have it.
-Split Second FTC, DSMConvert would be the one to talk to about this. It's not out yet, no one has used it, and I'm not sure when it'll be out.

Email these guys they have done mazdas and are the best solution for the ford ecu that our cars have .

Technically, I believe Megasquirt is a piggyback. It intercedes on behalf of the ECU for fuel (and spark if configured that way), but doesn't replace it for other functions. I toyed with the idea of using it on a couple other cars. There are a couple of problems I see with it....first, I can't control boost with it. Second, I need to use a MAP sensor. Does the Protege use a MAP sensor stock, or is it MAF based? Third, it's still a piggyback, so not the ideal solution. Possibility, though.
What's the MPI tuner?
Thanks for the tip, speedfrk, I'll be sure to check them out.

MegaSquirt is a piggyback and would fit within the rules. None of the piggybacks can control boost since our ECU doesn't control boost. It's all mechanical. You'll need a boost controller or a stiffer wastegate spring to raise your boost with anything you use.
p.s. the MPI Tuner is an SMT-6 that's specifically modified for the Protege. Google SMT-6 and you'll probably find a bunch of info. MPINick on the forum can give you any information you need.

I have never used megasquirt as a piggy,always standalone.it has a MAP sensor you wire into it,it CAN control boost,it CANNOT control the MSP speedo(reg protege's don't worry),it can do a lot more then ANY standalone on the market.
if you ever have ANY questions on it contact: kdh 51 (AIM NAME) he has done more megasquirt then the person who designed it.
he does it mainly on volvo,but none the less,he knows megasquirt better then anyone.

wait a sec, now I'm confused. If boost is regulated mechanically and not by the ECU, then how do computer plugins like the Unichip modify boost settings? How are people raising their boost? Which leads me to....
Is the wastegate on our stock turbos integrated into the turbo, or is it a seperate unit?

you have to hookup a seleniod that has the vacuum running through it. It will take the incoming reading and change it and send that new adjusted reading to the wastegated acutator that is part of our turbo. it will for example tell the W/A that it has not met it's limit and to continue to allow for more boost, once you have met the adjusted boost level via your boost controller it will hold it there.

That's okay, I understand now I think. I was just hoping to avoid having to trick the wastegate into giving me more boost. But since the computer isn't controlling boost and the wastegate is integral, I guess I don't have a choice....that's the only way to do it. So I'll be relying on a seperate boost controller, but I'm still not sure what to do about the fuel and timing maps. Returning to my original question, am I limited to piggybacks or using a standalone for tuning fuel and spark?
Piggybacks can do it, like the ones I listed above. Depending on your time table you might want to wait until SCT has their software ready. Then you will have control over all the ECU's parameters and you can reflash your stock ECU. They said it should be ready in November, so if you're building a car for next season you would have all winter to tune with it.
I tried to get the Tweecer guys to look at it. They said they could try to get it to work, but I never had the time to go down and visit them, and no one else was interested enough to volunteer. Seemed like it would be a very neat option to have.

This man speaks the truth. Although with the SCT Software you'll have control over your actual ECU so you won't be wondering if you have everything wired right or if your ECU is learing around it. You'll also have access to all the stock ECU's parameters, as well as being able to monter all the stock sensors so you can see everything happening to your engine. It's a built in scan tool so you can see everything and also read codes. If you're racing and you know what you are doing when you tune then something like this is what you'll want. You can also get it with a built in 2 step rev limiter, which would help you greatly it you have standing starts.apocman said:
This is the option I am going with, if it indeed comes out in November like they said it would. I will continue to be in contact with SCT and keep you posted on the progress.
