ECMlink sd setup ecm input... what???

[casperfast]

so im getting around to installing my omni 4 bar map, gm iat etc. i have the ecmtuning plug and play harness that goes directly to the stock 2g mas connector. the only thing i must be having a brain fart or something is... when i am at the "speed density" tab in red near the top it reads "assign map input pin and type" i click her and she takes me to the ecu inputs tab. now on here i see nothing allowing me to select the map input to the stock 2g mas input. is it the "baro", the "mdp" ?? im drawing a blank. thanks

The omni dsm 4 bar replaces the mdp sensor on the 2g intake mani and uses the factory connector, so you need to use the mdp input for the map.

The gm iat with the plug-and-play harness uses the intake temp input.

Because you're running the omni dsm map, you'll only use one connector (gm iat) from the plug-and-play harness. The other connector (for a gm map sensor) is unused.

Conversely, just for reference, if you had a gm map sensor, the baro input would be used for it.

 

[casperfast]

It is a gm style not dsm style map sensor and it plugs into the harness with the iat to the 2g mas connector. So i would use the baro? And what should i do with the stock mdp sensor? Unplug it?

Ah, my bad, I forgot omni had the gm option (otherwise, us dsm guys would be pretty spoiled ).

So i would use the baro? And what should i do with the stock mdp sensor? Unplug it?

Use the baro input and leave the mdp sensor alone.

This cable connects the IAT sensor to the factory Intake Temp input pin and the MAP sensor to the factory Baro input pin. So when configuring the ECMLink software, those are the pins you'll need to specify and use.

sweet. ok i will play with it tomorrow morning (fu#*ing swing shift) and go from there. thank you

No problem, good luck

 

[casperfast]

so i hooked it all up and made the ecu changes. fired right up no sweat. how does this look? i noticed that my combft is rich... hmmmm

 

[casperfast]

this one is after i did the sdve combft self adjust with the correct items logged duh

 

[c2ypt1c]

how does this look?

It almost seems like your global fuel is off. Perhaps it's because of that capacitor on the pump?

Anyway, if you apply the sdveadjtool(combinedft), you can see that your sd table wants to be lower (around 51). This should bring down your airflowperrev, which is currently elevated, and also raise up your combinedft and hopefully wbfactor.

Also, your tpsvolts are a little low, you should use the tpsadjust tool.

If you haven't already, review these:

Try what I mentioned and post another idle log...

 

[casperfast]

Ok. I will tomorrow morning. Thanks

 

[casperfast]

so i did a short cruise to the store, made the changes. i noticed that it smells..... odd? and on the way there was stalling at a stop. after i made the adjustments (in the store parking lot) i did not noticce any stalling or stumbling on the way home. here is a log of the short trip home (about a mile) tyhe smell is still odd, like when my old maf was all effed up. seems to be running strong. i only have a few hours a week that i can actually work on it latley. hows she look?

 

[c2ypt1c]

The main thing that concerns me, and I should have mentioned this before, is the 1500 generator (alternator) error code. You can see that your battery voltage is jumpy, which might be screwing up your idle deadtime. I recommend addressing this before moving on because it is just adding more variables to this process (and you need to fix it anyway.).

Can you just post an Idle log at operating temp? Make sure it is a decent length like 3 mins or so.

Also, adjust your TPS again...

 

[casperfast]

took care of the dtc, and re did the tps adjust. here is a longer idle log.

How did you fix it? Just wondering because the battery voltage is still weird...

Anyway, veadjust (along with other items) is calling for lower values. Attached are my suggestions. All I did was veadjust and interpolated the surrounding cells to smooth the transition. Give this a try...

 

[casperfast]

so i loaded your tune. im not sure if it is because it is 30* outside or not, but the car did not want to idle for about 30 seconds i had to give it throttle to keep it running. the dtc issue was most likely due to a half dead optima i was trying to revive and a loose B+ terminal, i changed the battery and cleared the code and it did not return. the idle fluctuates alot with these cams so that might have something to due with the battery voltage being jump. but after your tune i see my combft is much closer to where it should be, thanks. here is an idle log with your adjustments.

30* damn. Try messing with (raise) coolanttempfueladj in direct access.

but after your tune i see my combft is much closer to where it should be, thanks. here is an idle log with your adjustments.

Yeah that looks better, although the airflowperrev is still a little high, perhaps from the cams...

I'd say get some cruise logs next and start using veadjust. Just make sure to not overwrite the idle areas, and that there are no huge jumps between cells.

 

[casperfast]

sweet. i will do that most likely on saturday. thanks for your help !!!

 

[casperfast]

so i took the car on about a 20mile country road, lots of big hills up and down, long straights and sharp corners, everything looks pretty good. but i am curious about the timing that i was seeing when i was at higher rpms. heres a log of the fun

Good, now If you apply veadjust(combinedft) to that log, you'll get some decent numbers and will start to fine tune the airflow. After that, perhaps smooth out the 85 to 80.5 jump at (2500, 20.2) to (2500, 25.7) using the interpolate selection tool.

but i am curious about the timing that i was seeing when i was at higher rpms. heres a log of the fun

The timing is just referenced from the direct access timing table (TimingMaxOct). Whatever cell is selected on the table, that's what the ecu will shoot for, unless some other factor is interfering, such as, knock, timing sliders, coolant temp, etc. You can track the datalog and follow along if you'd like.

Looks like your error code came back...

 

[casperfast]

i noticed that. i geuss that red top took out my new alternator i will get a new alternator this weekend. ill apply those changes as well.

 

[c2ypt1c]

Sounds good. I'm betting your battery voltage will mellow out afterward

 

[casperfast]

hope so. kinda sucks though. that alternator is only a year old and the red top is only 6 months old. it is also the 3rd red top ive had in 2 years. i will not be buying another. i think ill just go with an odysey next time. as far as you saying to interpolate tool. is that just selecting all the surrounding cells and bring them down together and blending from there or is there a different tool? and also. i have been using the veadjustcombft, what would the veadjustsdratio do? i did both just to see the changes to the map and they are quite different.

 

[c2ypt1c]

Select which cells you want. Right-click and select "interpolate selection (linear)"

When you select a row or column of cells, it will give the linear average between the upper and lower bounds of the selection.

For example, lets say you select a row of:
[1] [0] [0] [4]

The result would be something like:
[1] [2] [3] [4]

Notice how the upper and lower bounds are left unchanged. Also, these are just example numbers to help you understand (values this low would be rediculous).

smooth out the 85 to 80.5 jump at (2500, 20.2) to (2500, 25.7) using the interpolate selection tool.

I gave you cartesian coordinates in (x, y) form

Here is the table with veadjust applied and my suggestions (mentioned above) for linear interpolation. See if you can get the same thing on your own.

and also. i have been using the veadjustcombft, what would the veadjustsdratio do? i did both just to see the changes to the map and they are quite different.

sdsetup [ECMTuning - wiki]

At the bottom of the page, you can read about the differences, but basically, sdratio is used in conjunction with a maf.

 

[casperfast]

i gotchya. but when i do this, i dont see the interpolate option when i right click

What version of ecmlink are you running? At the top of the application click Help->About and it will tell you.

The Linear Interpolation tool was introduced in v3.21.108 (11/12/2010)

You really should update to take advantage of all the newest features and bug fixes. This also means that you're going to have to update the firmware...
