Please contact me (PM or email) re: information needs for MS3 Basic.

How big is the controller relative to the LC1? Reason why i ask is because the LC1 fits perfectly in the little gap in front of the shifter right under the air bag light switch.

It's a bit smaller, and easier to mount due to integrated mounting tabs and the connector is relocated to the harness, instead of integral to the body. It's a better form factor.

The single ground wire is a bit of a mixed bag for me. It's working fine on the MTX-L, but the theory behind the divorced grounds on the discontinued LC-1 is technically better. The problem with the divorced grounds tends to be user error, which I assume is why they went away.

I don't mean to hijack here, but isn't the SLC from 14point7 a purely digital wideband as well? And if so, any advantages to the LC-2 over that?

Why worry about separate grounds? Connect the controller and the gauge grounds together. Whats the problem?

case in point:

lol.

I'm waiting for miata user review and feedback before I consider pulling the trigger.

Because MTX-L has a single ground wire, ground it to the power ground pin of the ECU. DO NOT ground it to the signal ground pin. This is true whether you are using the MTX-L's analog or digital output.

Also DO NOT shorten the MTX-L's wires if using the analog output. I suspect they are doing ground wire impedance compensation and shortening it will throw it off.

I need to get my MS3 Basic running, so I will get the LC-2 and put it in and give it a try. However, I won't have past experience for comparison. Conversely, that might be a good way to judge the completeness of the instructions.

Q: What do I change from the normal hook-up to use the digital interface between WB sensor and MS?

One of these.

TinyIOx v1.0 Board

MS3 basic doesn't support it out of the box.

Or, according to Posts #6, and #29, I need to be patient and wait for Reverant's Revelation.

#6 it'll require your ECU to be sent back and modified. There needs to be an interface between the digital ouptut of the LC-2 and the ECU

#29, just confirms an LC-2 will work with Revs ECU, which it will, using the analogue outputs.

Not really, because I now have an external module that connects to the Zeitronix/LC-1/LC-2/MTX-L/LM-1/LM-2 through their serial port, grabs the data, and pushes it through CAN bus to the ECU.

I've been trying it on my car for over a month now. Works great!

Nice :)

Reverant:

Please forward the details to me, or post. I will proceed with purchase of LC-2, and will need to know how to connect into my MS3 (present loom is set up for the separated grounds of LC-1) either analog or digital. If an internal interface is also possible (for digital input) I have the ability to add it to the PWB if you tell me what and where.

OFF_TOPIC WARNING: Also need to know what to add to make my MS3 Basic 4 spark drives rather than the two now.

+11ty billion to this. I've been waiting on this announcement for some time!

Does this also apply to the original LC-1 (which has separate grounds) or only to the MTX-L?

MTX-L only.

On the LC1, connect the signal ground wire to the ECU signal ground pin.
Connect the power ground wire to the head or block.

I'm guessing this doesn't matter so much when it's not feeding a standalone, correct?
