Alot of stand alone systems dont focus a whole lot on cold start, idle, hot start, and alot of other important things. I am not well versed in the microtech system however one a whole you have to think that this is the first time all these parts will be on the car at the same time and some this will be the first time they are being run why not start with a proven platform instead of adding another variable to go wrong in the mix that way if we do run into a problem we are not hunting down a bug in the tune of the engine. Speaking of which who is making the tune for the car and are you acounting for all these extra parts being put on
Why not use the msp ecu + a piggyback to adjust for the extra parts? Seems like it would be alot less hassle. In my case, I have the option of an ecu replacement or a piggyback. I'm going with the latter because it simplifies things alot, and it's less I can mess up tuning the thing.

I am all for the standalone on this one the MSP ecu (and most mazda ECU's for that matter) have a bad habit of learning around the piggyback creating problems that can result in some pretty nasty stuff. But personally i would hold off on the stand alone until the car starts and runs, i am not saying hey lets puts the msp ecu on and leave it for months but put it on and run the car for a day or two and get the parts broken in a little then put the stand alone on. The biggest thing to remember here is who is installing all this stuff and where we are installing it. Whereas kevin, scott, luke, and myself have a decent depth of knowledge and african american engineering we are NOT a shop who has been doing this for a while nor do we have the tools of a shop at our disposal like a dyno.

Aint that the bloody truth, man that would make things way more easier for all of us. I do agree with Korey on this one. It is a safety to make sure we have the essentials working properly before we play too much with tuning. If we go ahead with the full install then we might run into problems that react like similar problems caused by an unrelated catalyst, we could sit there and tune it out with the LP10 or LT10 whatever it is, but not getting anywhere.Shadow102 said:
all I have is the mazdaspeed protege T25.Gaboost said:
The way i had it explained to me once was like this: Your fuel system has whats called long and short term trim levels. Say for arguments sake your fuel trims are sitting at 0. You piggy back sends a false signal to the ecu in order to get more or less fuel example: you want to go lean so the piggy back modifys the signal to tell the ecu that you are getting too much fuel and then cuts back on fuel delivery and the ecu gives the car -1 fuel trim. Over time the ECU learns this value as being the "0" value and at the same time the piggy back is saying that according the the map its given (since a piggy back doesnt learn on its own) that hey i still need to tell the cpu to remove fuel at this point so now instead of fuel trim being -1 originally it is now -2 and so the cycle goes on. This is just a very crude example but you get the idea. Now i am not going to go ahead and say all piggy back systems are bad there are ones out there specifically designed for cars to do their job correctly and there are ECU's that are more developed like honda, ford, ect. I am not going to name system names but most piggyback systems for the protege have yet to crack the stock ECU learning curve. The miata may be very different seeing as there has been alot more development for that car. The most disapointing part of this all is that we have mazda alone to blame for this. Our ECU program is based on the EECV ford programing which the fuckus runs and i know my brother runs a plug in tuner with general ease as it just reflashes the entire cpu however mazda went and screwed us when they threw in there own little bits of code and re-wrote the programing so we cant use the smae flasher like the ford uses. Your best bet is to research into the systems and figure out how they work, what they tell the ecu, if the bypass anything, ect. Like i learned as a little kid whatching captain planet knowledge is power...and in this case horsepower in the form of fossil fuel to pollute the world (ok so maybey i didnt learn a whole lot from Capn. P.)
