E-Manage powered Mazdaspeed!

turboge,

I don't believe you have to change the rotary switches. There is a pull down menu in the parameter setup screen you can select different MAFS from. If you change the rotary switches, the emanage will not know what the original MAFS is and may not compensate/interpolate values correctly. I will find out. Like I mentioned... I don't think anybody needs a big MAFS until they hit 250whp. I guess we're just preparing for it.

There is a Airflow adjustment map which modifies the MAF readings, and the additional injection map that adds/subtracts duty cycle from the injectors. There is 1 timing map, and theres a Boost Pressure Cut prevention map, also a map for open vented BOV's. The rest go unused for our cars.

Yea, I'm currently running the fuel adjustment map, the airflow adj, and the vented bov map. Going to wire up the timing control over christmas break probably, and see where that goes.

If the emanage can handle a bigger maf, that will definately come in handy later on when my motor is built.

Chooch - I just noticed that feature in the software. Looks like a cool mod to play with. I think it should work fine as long as it can convert everything correctly.

good luck man. terry and i tried it the e-management on my msp.
it had alot of issues. the car continued lean out when you gave it gas.we tried all different kinds of fuel maps but it continued. the timing fuction works well. let me know how it goes.

thanks justinh

 

[MP3skaterNC]

Yea justin I dont know what was up with that. I was hoping that when i come back up in a few weeks that we'd be able to attempt it again, but then spool closed.

chooch its probably been said before, but what kind of turbo setup/ n/a setup is your emanage controling. And what kind of numbers have you made thus far.

from my experience with the sr20, they ran off the stock maf until about 300whp...after that it wouldnt read......im not sure the size of our maf compared to the stock maf on the sr20....does anyone know were i can get factory plugs so i can attempt to make a harness to plug my future emanage into??? also turboge, i was lookin at the injectory harness and ignition harness options for my emange, basically ill be covered on all the maps correct? im still confused on the pressure sensor, it doesnt actually replace the maf but aided is right? and what does the airflow adjustment map do in the way of tuning.....this for fcd purposes?? sorry for the newbie questions, this is gonna be my first multi-aspect tuning plus im helpin my nephew tune his honda using hondata...thanks in advance for the help

The emanage doesn't control the O2 in anyway, so, a O2 voltage clamp like FM offers may correct your tip in lean problem.

The pressure sensor may not be as beneficial for the MSP as it would for a n/a protege. For fuel anyways. The stock MSP ecu is already programmed to compensate for boost were as a n/a ecu will not. But the MSP could take advantage of the pressure sensor for timing adjustments, such as, retarding more timing in relation to boost. The FCD feature of the emanage is unrelated to the air flow adjustment map. The air flow adjustment map manipulates air flow sensor voltages to fine tune a/f ratios. The boost limiter cut(fcd) feature has its own map.

 

[AutoBox]

thanks for clearin that up chooch, im def gonna be im'in you guys when my e-manage comes in lol....im gonna go ahead and order the pressure option as well and go from there.....does anyone know where i can get electrical plugs to fab my own harness for the e-manage???

No a voltage clamp is not needed on a MSP. This is only for a protege ecu. And the car was not leaning out at partial but alll throtle ranges...another indication that a clamp would do nothing. A side note a voltage clamp will be needed in conjuction with the emanage on non-msp cars.

Also with the pressure sensor you just get the ability of higher resolution tuning on timining and fuel maps.

In regards to Justins car we had some issues with his MSP not working. But I really think that this had to do with the way we installed it or something. Something must have been incorrect and caused the issue with the car. We got it to run on MP3skaterNC's car flawlessly.

 

[spoolinmp3]

To add to this.....the Airflow adjustment map which modifies the MAF readings is good for pulling out fuel and the additional injection map which has a broader span of resolution is used to add fuel. And you can layer the a/f map to lean out humps in the a/f. Its not reccomended to use the airflow adjustment map for fuel enrichment purposes.

Also Turboge if you need would like some info in regards to fuel maps for reference PM me.

Basically I used the relative pressure KPA display for tunning since it has a nice vaccum/boost map setup

 

[AutoBox]

sounds good to me spoolin, when u guys talk about layerin maps do u mean you can actually lay the maps over each other and compare them along the rpm range to get any flat spots etc?? i remebr seein this done on a guys wrx, i forget the ems he had but u could put the a/f map and say ignition map on top of each other and go along the rpm range and adjust ignition timing to clean up flat spots in the a/f map....this is what the e-manage offers???

 

[spoolinmp3]

AutoBox yeah you kinda got the idea....but I am talking about 2 a/f maps that teh emanage utilizes. One is primarily used to add fuel and the other is primarily used to take out fuel.....one can layer these maps....running them simultanoeusly in a sense to get nice clean smooth a/f's
On the MSP I would imagine you would be pulling more fuel than anything else and adding fuel at higher boost levels. The timing control and leaning out fuel is essential on the MSP for a more powerful car

 

[spoolinmp3]

We got ignition to work but did not have time to experiment with it long enough since we closed shop. The only thing that is worrying me is the frying of coils......however the emanage ignition harness connects like the J&S retard unit so all should be good.

MP3skaterNC is driving up from NC to my house so we can finish up his timing maps and we will no for sure.....or if turboge gets it done first

 

[MP3skaterNC]

Yea, the frying the coils is worrying me somewhat, so i just went to the dealer yesterday and ordered 2 extra heh.

We should have my car done in the next few weeks if i can find the time to get to VA between family stuff.

 

[AutoBox]

hmm does the e-manage over load the coils?? or is there somehting im mssing about this whole ignition thing? is there something special you guys did to get th eignition maps to work on th emsp???


btw, does anyone w\know were i can find connectors to make a harness for the emanage for our cars??

Yeah frying coils sucks. . .I should know. . .
And the MPI hooks up just like the J&S and I have a J&S as well and guess what. . .cook, baby, cook. . .I'd like my coils extra crispy! So, screwed that one up, but it only cost $27.72 to get two shiny new coils. . .so whoop-di-do!

Best of luck, hope it works out!

Update 12-13-03:

The e-manage and the Profec e-01 are both working flawlessly right now. It took me the better half of a day to remove the haltech, clean up all the wires and get both e-manage and profec installed. I accidentally left the MAF unplugged on first start and threw a CEL, but plugged it back in and reset the ecu and things are working perfect.

I haven't had a chance to tune anything yet, but everything is setup and ready to go, ignition control and fuel control. I'm monitoring everything currently and still have to hook the wideband into the Profec.

Pictures coming soon.

coool turboge.....so what was all this hooplay about the timing maps not working on the msp, have u solved this???

My bad... overlooked that it was a MSP.

 

[napmsp]

turboge, what was tha install time on e-manage+e-o1 also what is the trick to get tha timing working that everybody said wouldnt work
