dont forget about me nick

I have contacted some people that i work with. I am awaiting some responces.
Trust me I didnt forget.
Can you get a pinout for that ecu? Or just a basic wiring diagram from YOUR manual there in Australia?

 

[twilightprotege]

i can have a look around yeah. i'll see if a dealer can let me photocopy their manual

 

[thewrench]

Perf, Maybe I missed this, but is your deal going to use a MAF or MAP or both. If a MAF is needed will it be able to use a larger one? I know the arguments about whether a larger MAF is useful, and I also understand (somewhat) about the scaling. These are leading to another question, but that's for a different thread.

Thanks

Good questions.
But at the present time i dont want to give away any info as to HOW it will be functioning . I think you understand why.
I will go into it in alot more detail however once we are done tuning and provide the board with some prelimanary dyno and road results.

No this is a plug and play Engine Management System. The stock ecu is used for other functions such as your various output controls. The AC switching, Tach, and speedo.
Where you are getting confused is that BOTH ECU will be used. They will both plug in without any cutting or splicing. We have all the adapter harnesses you need to run them both in parallel. One controls the engine managent properties of Fuel and ignition and the other the outputs for display funtions

AND it will be affordably priced right? Like $600-$700 range!? :wink: :wink: :nudge: :nudge:

LOL
I really would love to give things away if i could, but the reality of the situation is that it wont be in that price range. It is a complete EMS system of the highest quality. I cant even begin to buy the unit myself for that much. I cant comment on pricing yet but i will soon.

Ok no offense perf but honestly if people want management in the $600-700 range then they should do the MPI tuner. More then a $1g is haltech territory. U might want to setup some demonstrations or test vehicles to prove the value of your forthcoming ems. This is said in the most respectful way but u should consider this. MPI already has 2 cars testing their competitively priced units.

There are a lot more than 2 cars out there. I guess time will tell how they "work" in the long run, but there seem to be some satisfied customers out there, so despite all the crap we've seen in some of the threads, it is working.

Can't wait to see all the new "systems" come out and then to see results of how they perform!

 

[Kenetix]

I used a Unichip setup with great success.

 

[akhilleus]

but not on a protege....nice rx's though...lucky bastard

Yeah well, I think I will have to wait...

...in the mean time I will begin to spend my money on rice stuff...

This gets tricky...The potential management system buyer needs to lay down a couple of goals to make the right the decision...600-700 dollars is very expensive for a piggyback...The MPI tuner is currently the highest priced piggy available...The Unichip is up there too, but not available yet...The AFC option is still being worked on, and is much cheaper than both...

In either case, Nick's setup is a full standalone...And $600-700 almost never gets a new full standalone running a car properly...So realistically it will be more in the price range of other full standalones...The advantage is the plug and play nature of it though...You won't have to spend hundreds of dollars to get it installed, or spend the time to do it yourself...you take 15 minutes (or less) and plug it in...

So the buyer needs to determine which system they need...If you are looking for less of a degree of control for a less modified vehicle, you probably won't need to invest in a standalone...but if you are seriously modifying the car, and need complete accurate control over everything related to the engine's tuning...You do need a standalone, and a piggy won't cut it...

But this post is only to not confuse MPNicks prices with standalones...regardless of any claims made, it is not a standalone...and appears to be experiencing similar "piggy" problems to the emanage, at least in some circumstances...But it offers no where near the control of even simple standalones (and Links "simple" standalone is in the exact same price range as MPNicks MPI tuner)...So someone looking at the MPI tuner, probably isn't looking for a full standalone...and only requires moderate control for a mild street setup...

 

[akhilleus]

exactly..although i wasnt aware that there had been problems with the mpi tuner..please fill us in.

 

[DooMer_MP3]

Just look at the FI section here...

 

[thewrench]

I'd like to just clarify my thinking on something here. When running a standalone, such as a Haltech, in parallel with the stock ecu, you would add a MAP for the Haltech, and retain the stock MAF for the stock ecu to use for its utilities, correct? Is there a way to get rid of or replace the stock MAF? This is just assuming perf doesn't work some magic to get rid of the MAF, since he ain't talkin'. I'm wanting to run a larger throttle body, but I'm concerned the stock MAF would nullify any advantage. Keep in mind I've got the ported intake to put it on. So let's argue that out. It's been discussed before, but to no decisive conclusion.

 

[twilightprotege]

i cant wait to see the results of your IM

i'm almost definately going to customise my IM in the near future - open up that stupid VICS chamber

 

[thewrench]

I wish perf would get his stuff out so I could make a decision. I'm trying to do cams ASAP. Then I'll work on the intake. I want to do the thermal spacers and port matching, but if I go with Corksport's or Sunbelt's throttle body I want to go ahead and set up the mani for it all at once. So while management will come later, I need to know how I'm going to do it now. When I talk to Sunbelt about the cams, I'll ask about their intake mods, too. I've got my doubts about what you want to do with the intake, but maybe we need a new thread for that, hehe. (too much volume for any low end power)

I am not sure on how Nick is handling this...but in general when switching to a MAP over a stock MAF there are a few ways to get rid of the original MAF altogether while running in parallel with the stock ECU...You can use some "virtual" sensor systems to allow the ECU to think everything is normal, and they are usually pretty simple despite how it sounds...There are also some other ways around it...In some cases you don't really need to do anything...If the stock ECU is not controlling anything but the tach, AC switching and things of that nature, meaning no engine control timing and fuel wise...You may not need to do anything...Just pull the plug or bulb for the MIL/CEL on the dash, which won't matter becasue I don't think the standalone will have any control of it anyway...So the stock ECU will light it up, but only because it is super pissed that it isn't being shown anything...the standalone can still handle everything else...i know that is the case in some situations with other cars...Not positive if that is our case, but I know at least one of the couple options will work to get the stock MAF out of there if you need to...

 

[thewrench]

Wouldn't the stock ecu still need the MAF for determining engine load for controling A/C, auto tranny shifting, fans, etc. Also, and I'm not at all sure of this, but I seem to vaguely remember something about letting the stock ecu control idle, or cold engine starts, or something, geez I just don't remember specifically, and I'm NOT going to reread his Haltech thread So that the a MAF had to be retained. I'm not opposed to having one, just something bigger than stock if possible, or necessary. Oh BTW, not arguing with you, it's just a nagging something in my mind, that I've heard that before.
