What's the difference between wideband input and wideband digital input?

I don't have my Basic MS3 yet (any day now, hopefully!), but my understanding is that 'windeband input' refers to the standard analog 0-5v input, and 'wideband digital input' refers to a serial input that can be hooked up to the serial out of your wideband controller, if it has one. He sells a separate module which connects to the CAN bus inputs on a regular MS3 which provides the same functionality (https://www.miataturbo.net/ms-labs-m...terface-78449/) but I guess the Enhanced MS3 has the functionality built in.

I'm not sure but I'd imagine the big advantage to serial input is you don't have a chance of the gauge and TunerStudio reading different values. However that's usually not too difficult to fix if it even occurs in the first place.

There may be other advantages that I don't know.

I bought the wideband CAN interface module for my MS3-Basic for the following reasons:
  1. It should completely eliminate ground offset due to wiring variables
  2. Insanely fast wideband input
  3. Why use touchy *** analog when digital is available?
  4. Its ******* cool
Yes the box adds an additional point of failure, but the analog inputs are still there on my Basic. A software change and some minor wiring and I can still drive home. My CAN module will be going in sometime in the next week along with a new LC-2

The box also acts a failsafe. If the wideband supports it, the module will read error codes from the wideband and prevent the MS3 from going into closed loop fueling. It will also do the same if the wideband is not responding on the serial port. The MS3 itself will not enter closed loop if the module is not working.

So all in all, its safer than the analog input.

On the Innovate LC-2, the gauge is analog input as well as MS. To know the correct digital output of the controller, one must also run Logworks, the Innovate software that displays and logs from the LC-2 serial port.

To be all set up right, one must compare 3 gauges, one digital and 2 analog.

With the module, it is only two. And, the one that is running your engine is the most accurate one.

With that comes a question for Reverant: Is it possible to input both the CAN and the analog into the MS3, run on the CAN but display and graph both?

I don't see why not. Just create another gauge in TS with that input and you should be good to go.

Hey reverant, i'm new here and i got my hands on a BEGI turbo kit.

All i need is the ecu and wideband now.

Some users on this forum headed me your way.

So, what's the deal with your megasquirt setup ? I need help.

Is it Plug n play ?

How much is it ?

How can I buy it, I need it pretty quickly.

Thanks alot ! (you can pm me if youd like)

Yes, Plug-n-play. Read the thread and it says that in the first post.

PM him and he'll tell you how much and his PayPal address.

Quick is relative. He's in Greece and builds them to order, when you pay. They're not sitting on a shelf waiting for you to pay for same-day counter-to-counter International shipping.

I am glad I found out about this while Reverent still had my unit. It's a no brainer for $100. I am looking forward to the arrival of my MS3 more than ever now.

Yep, I got my Basic MS3 with serial wideband unit installed yesterday, and it was very reassuring seeing the AFR's in TunerStudio correspond exactly with what the AEM wideband gauge was showing. Didn't have to do any calibrating or anything, it just worked out of the box. Really glad I got the serial wideband option.

Awww...you guys are giving me all the warm fuzzys for similarly ponying up for the wideband CAN module.

Yay for technology!

I held off buying an ECU for over a year waiting for the MS3-‹bermensch before deciding to go with the Basic + wideband CAN interface module. After my experience dealing with ground offset issue with my DIYPNP, I regret nothing! Its seriously worth it. If I can make it work, you can make it work.

S/N is 12616

Here is the I/O list I have for the DB 37:
28. A 37-way connector with pigtail is included with your ECU. There are several free- hanging wires on the connector (depending on your request):
• White/Red: Fused 12V power supply for your wideband ONLY. Has an internal 6A fuse.
• Black/Yellow: Ground / Heater ground (for LC-1 widebands)
• Black/Green: Analog sensor ground.
• Yellow - Wideband input. Connect this to your wideband analog output
• Grey – Switchable tables (optional). Connect this to a ground (through an on/off
switch) to switch between VE/Ignition tables.
• Brown – Launch control input (optional). Connect to a ground (through a
momentary switch) to enable launch (when pressed).
• Brown and Green (twisted together) (optional)- Ignition output C (brown) and
ignition output D (green)
• Pink and Violet – Injection output C (pink) (optional) and injection output D
(violet) (90-93 only)
• Pink and White (twisted together) (optional) – Oil pressure input (white;
resistive), oil temperature (pink; resistive). Connect to sensor. The other end of
the sensor goes to ground.
• Violet (purple) (optional; not available on the 01-05 as the signal is already
routed through the stock harness) – VVT control solenoid (negative side) to use on 01-05 engine swaps. The other pin of the valve needs a switched and fused (5A) 12V power supply. The valve does not have a polarity.
• Green - Boost control output. Connect this to a boost control valve. The other wire of the boost control valve needs to be connected to a switched and fused 12V source. A 5A fuse is recommended.
• White (optional; not available on the 99-05 as the signal is already routed through the stock harness) – Knock input. Connect to a knock sensor.
• Red – Datalog start/stop.Connect this to a switched 12V source (through an on/off switch) to start/stop datalogging to the SD card.
• Orange - Free programmable output (Nitrous 2), low side. Can drive any load up to 5A.

Questions:
1) Where do I input the CAN from the Serial to CAN WB interface box?
2) 2nd to last is red wire for momentary contact to start / stop data logging. Is there a companion output to drive (sink) and LED that shows status of logging?
3) I want to us 1 or two other outputs to drive LED's as annunciators. Since I am not planning to use VVT, can I use the purple for that? My thought is to combine AFR Warning and Knock into a single out. Not sure how to do this summing, or if those are possible over at the Advance Engine area. Any help welcome. The other one would be a light that would come on if CLT goes above 235*F.

1) Pins 8 and 9. Pin 8 is CANH (white wire), pin 9 is CANL (black wire).

2) No, you can use another output to do that, for example Nitrous 2 (orange wire).

3) Yes, VVT can be used for that. You can the use the EBC output to drive the same LED.

Default And to wire the CAN module

OK. I will be using EBC for EBC. So, then I'm out of outputs, yes?

On the WB Serial to CAN module, there are also Red and Black. Is Red switched power and Black Ground?

You can add a couple of low power outputs by connecting a couple of wires from the MS3 daughterboard to the DB37 connector. Email me for more info.

Red is 12V, black is ground, correct.
