ECMlink My first V3 Idle log, critique it please

[awdtalon4451]

Hey guys, I finally figured out how to post my logs. First idle log since I got v3. Ive read over the post's reguarding what to do before posting and how to's on Ecmlink. I need some help learning the ropes of V3 and fine tuning my idle and cruising as im still VERY new to this. I have some questions but ill wait to see what others say first. Any help is much appreciated. Thanks guys

BLT held to 23psi
Timing is set to 5*
Motor is in overall good health
TPS has been adjusted
base FP is 37psi, 550cc's
Compression test showed 150lbs acros the board
Wiring and sensors are well
WB is ran in fron O2 housing, also runinig narrow band sim
Running 93oct
No dtc's or cels's

You need to assign your wideband and map sensors so they can be datalogged. You do that in the top table on the ECU Inputs tab.

Once you have them assigned, log them and rename them to "Wideband" and "MAP" in the display parameters.

thanks calan. Im glad you mentioned this cause this pertains one my questions. When i installed the Mtx WB i ran the yellow wire to pin#4 to narrow band sim. In order to datalog the actual WB A/F's do i run the brown wire from the WB to another ecu pinout? Another thing is do i have to run the MAP sensor to a ecu pin also?

Nope, you will log the wideband signal on the MTX-L from the yellow wire.

Go into your ECU inputs tab, select Linear wideband from the Connected Sensor drop down next to Front O2 pin, and then assign it a name. Then go turn on narrowband sim (if not already) and set the switch point.

Yes, it would be ideal so you can log this, if you have one. I can't say I've seen mention of it though.

Ok ive got the WB logging now. I've read that the switch point should be 2.45v for the Mtx-l. If this is off by much will it affect the readings?

Damn i don't have an aftermarket MAP sensor on hand. Is there anyway i can get around this until it get here?

I pulled a log on the way to work this morning but i can't post till i get home. My wideband and ecmlink WB log don't match up. Ecmlink reads 1 point lower than my wideband.

Did you set the proper linear wideband properties (if you choose LinWideband)? Double click on the wideband value below the graph and check the properties. You can find these properties by opening and connecting the LM Programmer software.

Yep i selected linear WB, i have the programming cable for the Mtx but i don't have a 64 bit connector to connect to my laptop

You're gonna need that. I just figured it out with my setup, ecmlink and LC-1. I believe the LM and LC use the same software. Well when you hooked up the Yellow/Brown wires, they were both aux wires which by default will send narrowband signals to aux1 (not sure if yellow or brown) and Wideband 0.00v - 5.000v to aux2(again, not sure if yellow or brown). The solution, in the programming options for the wideband (logworks program) you can change both aux settings to 0.00v-5.00v so that both your ecu and gauge get the same reading ranges. From there, eculink can take in the full volt range then simulate the 02 narrowband if you want it to. I just fixed this issue with my car no more than 3 hours ago, my gauge read through a broad range, from as little as 8:1 - 22:1, the ecmlink logged only 11:1 and very rarely moved between 8:1

See if you can borrow someones laptop of find a serial to usb converter? (Do those exists?)

Serial to USB cable:
usbtoserialadapterinfo [ECMTuning - wiki]


LC-1
yellow - narrowband
brown - wideband

MTX-L
yellow - wideband
brown - narrowband

I'd love to know why they switched them...
