I have my wideband set up and working, but realized there isn't a graph display for it.. It just shows in the live data window when your logging. I do understand that it shows when you hover on a graph, but I think there needs to be a combined graph where you can pick the data you want displayed on the same graph, I can output it and do it in Excel, but I'm too lazy..

This bad boy works fantastic though.. I got an even better Idle from it than even my blowthrough sensor adjustment could do.. The low freq MAF clamp works wonders, buys me time until I can reflash my ECU to match the required fueling at idle.. I'm not joking, my trims are within +/-3% now.. The OBD-II feature built in and live adjustment made getting this up and running took minutes..


A few suggestions though.. The GM map sensor is capable of reading engine vacuum, so the software should show vacuum and boost, it helps to tune idle when your planning on logging data to do reflashing..

You need to add user adjustable calibration settings to your analog inputs, and variable output based on a table of some sort.. (either PWM or Voltage) This way you can use it to either control boost or water injection (I do know this is an upcoming feature though so its not important)

Oh, and I have a type K egt probe.. Need the adapter for it.. (or is it just a 5v source, ground and the return signal is the result?)

Oh crap, I never took pictures of the setup as installed, I added my ApexI AVC-R and a shift light to the wiring harness.. My only question is where are you guys hiding the unit, I can tuck it behind the glovebox but I need to wire up a remote switch for the OBD-II jumper so I can reflash my ECU, off to radio shack!

 

Oh and when you live update the tables, if you hit OK before changing to a different cell (commit the change) the program gives you a blocked I/O error.. I'll send you a snapshot of it later Tom..

 

Are you using a USB to serial cable? I never get that problem with straight serial connection.

Also, AFR graph, do you mean combined into the road dyno output or just a seperate graph in the live log? You have to make sure you have your spare input set to the right wideband in the software to see it. My zeitronix live logs in a graph fine:

 

Good to see you like it so far Jack. If you have the wideband set, just need to turn the view on. Right click on one of the windows and select view then air fuel ratio. That should bring the window up. Then go and auto arrange.

Tom knows about the vacuum thing. I've mentioned it to him also. The reason why that isn't in there, is the original map sensor he setup didn't do vacuum. So he didn't add it. It should be in the next set of updates I would think.

Yep, the egt adapter is just that, 12v, ground and output.

I made a small bracket that I taped it to and it bolts behind the glove box.

Thanks guys.. Yeah I figured it was somewhere I wasn't looking..

 

Jack - you probably didn't see the AFR graph because the right-click menu entry changes from "Spare 2" to "Air/Fuel Ratio" after you select a wideband type.

The lower MAS clamp idea came from EvoM user gunzo - he gets the credit for that good idea.

Reading out vacuum is Ivan C's idea, and will be in the next release.

That error is new to me. I'd definitely like to track it down.

Tom

 

Yeah though I do recall setting the input type, I don't recall doing anything on the graphs so thats definitely it.

The MAF clamp is a really good idea, I had been doing it through my blowthrough's karmann converter box, now I can put the karmann converter settings back down to normal airflow at idle, and let this do the job. This in turn gets my MAF scale back in check and I can tune the car in a manner that lets me transfer these values easier to the ECU (and have data relevent to other users who still have a stock MAF)

Right now, I used the MAF clamp, and added a few degrees of timing to get my idle to smooth out until I can finish my turbo and injector installs this weekend at that point I can go through and transfer some of the settings to the ECU and get the car to run well without anything helping it.. Once I do that, I'll do a base tune and then use the ECU+ to tune on top of it.

 

what is lower mas clamp?

 

It's a setting that will only allow the mas frequency to a certain point. Example, if I would set it to 40hz, the ECU would never see a reading below 40hz. It's a great way to smooth out for big cams.

Ivan

 

yeah Its great if you have inconsistent airflow at idle..

Anyway, you were right, I forgot to set the spare input to my WBO2 sensor.. In reality I have the software installed on several machines, I just forgot to set it on the machine I was using.

 

I know your problem, I have the software installed on a bunch of computers.

That might be something for Tom. I wonder if it would be possible for the log file to store those settings and the software could display the correct sensor without user input. Then when other people look at the logs, they don't have to guess what sensors are used.

Ivan

 

thats actually a good idea.. a "Log Profile" of some sort so when someone opens up someone elses logs, they see the same data...

 

We've mentioned that to Tom before. I believe he is working on it.

 

managed to get a Drwatson today while logging.. I'll forward it to you later when I get home.

 

oh so this is a sort of bss bump work around? is that what they do in dsmlink?
