i dont generate boost so how would i be able to tune withougt boost...
0 vac. As soon as it reaches 0 vacuum you may switch to open loop.

"may" is the key word. WOT on some protege ECU's does not mean that it will go into open loop. Gear or "demand" Load along with rpm will designate the transition into open loop. The MSP has different drive cycles.igdrasil said:0 vac. As soon as it reaches 0 vacuum you may switch to open loop.

I understand that load is load, but the programming of each of the 3 ECU's is different, which makes them change to open loop at different times and conditions...and each ECU does not do it the same each time...I was just wondering what sensors the tuner is intercepting, and what it is doing to make the mode switch...In stock form not just one sensor is creating the switch...The car will run in closed loop in most cases to almost 4,000 rpm at WOT before switching to open loop...and at WOT the TPS sensor is maxed out...So it has to take input from the MAF as well (You can also hit open loop while at partial throttle)...Are you manipulating both of these?...Or does only the MAF reading determine the switch?
In stock form the Protege may not switch over at 0 vacuum. THis is why we read the boost load and then adjust for ourself when we hit boost load.igdrasil said:0 vac. As soon as it reaches 0 vacuum you may switch to open loop.

MPNick said:We are looking for boost load. When we see boost load we kick it into open loop mode. It can happen at WOT first gear or it can be part throttle four gear, it does not matter to us. When you hit boost load it will changed over. You can tune it yourself for your car. You have to take into account more then just the cars ECU. You also have to take into account what turbo, what size intercooler, MAF size and intercooler tubing. This is why boost load is the most important thing when tuning a turbo car.
Thanks again

DooMer_MP3 said:The part in bold. That is what Installshield wants to know (and me, and many others). We already know you use boost to sense when to do it. But HOW do you "kick it into open loop mode"? If you don't want to tell us because its a trade secret, just say it!
Either way, it looks like you've finally got a pretty solid setup with the MPI tuner. When I go turbo, I want stock MAF and NO extra injectors, so I'm liking what I see here! Good work.

Installshield 2 said:Thanks Chris, that was exactly what I was getting at...and I figured it wouldn't get answered, but if it is something he does not want to give away he should mention that...
I am not going to start throwing s*** about this, I have learned to live with those types of replies...BUT please men, make sure you yourself are given this information before you drop over half a grand for this tuner...If MPNick wants you to sign a waver or something, making it illegal for you to reproduce the specifics of it that is fine...just as long as the end user knows exactly how this thing works...that is BY FAR the most important part...
I don't have the cash yet for any of these ECU upgrades, piggy's or standalones...I am just trying to get as much info as possible out of this system, so potential buyers are not misinformed...So if any of my posts seem to be pesimistic, or always seem to raise the BS flag on MPNick...I apologize...That is not the intention, it is simply that the people that are investing the money on this system NEED to know every single thing about every aspect of it...
so someone that owns one, let us know that you were given tons upon tons of info on it from MPNick...IMO MPNick attempts to create an illusion that he has no competition in this market, and he very much so does...The absolute best and most successfull ECU related parts manufacturers will always lay down the strengths and weaknesses of the system...Every one of them has both for the most part...and they will even recommend other brands that may fit your application better...I understand that at this point, available upgrades are a little hard to come by...but MPNick should at the very least show how this tuner sums up to that of Link, Haltech, Motec, Apex'i, Greddy, or others...It may have huge advantages, and it most likely will have some disadvantages too...potential buyers need to be informed of this...
