the injectors are the money shot. I swear it will make mpi tuning cake.

 

[apocman]

no need for a MSP ECU if you have the MPI, some people just buy the MSP ECU and not the MPI or any EMS and run around stock boost

xtra injectors = teh win

Got my MPi in... N/A style, and all. But the thing is most certainly causing more issues than helping, so far. Won't idle properly, and I don't really have a 'base map' to work with, since no one has really posted a base map at all. I've gone over my wiring twice, but I intend to do it a third time. I'm getting lots of backfiring and sputtering when it DOES start, which it hasn't done since the second try. I pulled the coils while installing it, then reinstalled them afterwards, just to be sure. Not sure exactly what's going on at this point. Any suggestions, folks?

N/A is different then FI so that's why there are no maps, not many N/A guys. What settings do you have under global settings? Negative numbers add fuel and positive number take fuel out for N/A.

Thanks to Bigg Tim and all the others:

I finally got my MPI to WORK!!!! INSTALLED IT TODAY... MY CAR IS RUNNING NOW.

Its not runnning great, coz I dont have a good map, but at least its working!!!

So right now, I just need to get it tuned.

 

[ca_deal1]

Can someone sent me a basic map?

 

[flat_black]

N/A, or otherwise? I have four or five.

 

[flat_black]

Ahh, hell, I just uploaded a few. Here's some:

I'll add more to the archive if people want.

I just looked at your instructions and it says youshould have a module with the MPI......do you? If you do and you have all the settings right, then it should be running. I'll send you my map I used when I hadmine hooked up like this. There will be a lot different since I am turbo, but the settings should be the same.

cadeal---congrats man, glad she's working. Let me know if those maps don't work.

 

[flat_black]

I do not, actually... And according to Nick, he said I shouldn't, and that he actually sent me the wrong instructions, so I'm waiting on him sending me the new ones, then I'll update the instruction set I have on the site.

Now that you say that, I remember him telling me he changed the way the N/A setup uses timing so you won't need the module. The new way gives more advance capabilities which you N/A guys want. My settings should work for you though.

 

[flat_black]

Crank the hell out of the advance, whoo. =) I actually have the MP3 ECU, so advancing it further is only for a couple spots; At some points, it actually hits 63.5 degrees of advance timing, so in those spots, probably not so much with the adding timing. I can't wait to get this thing working, so I can start tuning the car a touch, then move onto the 'next step'.

Right on!!! Let's see some dyno's of it when you're done, there are non of the N/A setup.

 

[flat_black]

Yeah, you'll have dynos after I swap on the new-new head (Jeez, I have, like, three ported heads now). Once that all is done, and I get a good tune, I'll have pre-tune and post-tune dynos, then I'll do one after I tune my ITB's, the final(ish) piece of the puzzle.

are there any maps for 4psi?
That's all i'm going to be running for the time being. I don't have an EBC yet... so i'll just run 4psi until i can acquire an EBC.

I have a question in the install manual

Step 4: Install the MPI Tuner wires blue #6, green/yellow #11, black/white #10 and the green Turbo Module wire to the PCM light green w/black #88 wire that is coming in from the engine side.

I did that and used the 1k resister( the way Big Timm's MAF hookup pic), the car wouldnt run(same bad idle as last time). The only way we got it to work was take off the green Turbo Module wire(since in Big Timm's pic was is no green TM wire). How the car idle and runs.

Now here is the question: What do we do with the green TM wire? Should it connect to anything? Also, when idle(500-900rpm) I need the fuel to be +5 for the car to idle well. If I have less than +5, the car will die. Is that normal?

 

[Lil Freek]

anybody have a copy of the SW and a couple maps?
i just wanna play with it on my computer and see if i can figure out something safe for 4psi

That part above is a little confusing, can you clearify?

The fuel cal does not have to be set at certain number. All that matters is that you get around 2-2.08v at idle. That's what the fuel cal does, gets the whole map in that range. So if you need a +5 to get there then cool, but if you need a -50, then that's OK too. Whatever works to get you in that range is what you want.

In your MAF hookup pic there are only 3 wire from the MPI connect to the #88 wire that coming in from the engine side. There is no green turbo module wire. What do we do with that wire?
