I will, thanks. I will also need some direction on how to ID the I/O's and the parameters I am looking for, as TS does not seem to correlate all parameters, e.g. I know there is a knock annunciator on TS, but how do I map it to the I/O. I will detail the questions in the email.

Love me some MS3Basic

 

My MS Basis is on the way from Reverent. I am impressed with his level of service and attention to detail for the base tune. The digital wideband option is a nice addition! Amazing level of control and options in such a tidy cost effect package.

Thanks Dimitris!

 

Just wondering if anyone knows how to feed an aftermarket water temp gauge from a basic ms3, I have a stack gauge I want to use but assume the feed it requires is different to that of that stock gauge so thinking I could feed it something from the MS?

 

I would imagine you could use one of the spare analog inputs, provided its 0-5v

 

He wants to power the gauge. The answer is to just run another sensor.

 

Yes just seems intercepting the stock sensor would be neater.

 

What does it take to get AC working with the MS3 basic?
Also I read it somewhere but now I can't find it, what do I jump over for a tach signal with MS3 basic?

 

The A/C works out of the box on all Basic MS3s.

I need to look up your ECU to answer your second question, as I've been strapped down for the last couple of days with a bad back. PM me in a couple of days.

 

Hmm... AC button doesn't even turn on the second fan. Maybe i need to do more digging into why it's not working. May be bad fuse or relay.

I'll PM you this weekend. Thank you.

My question is how does the wiring differ if you were to run the MS3 parallel with the stock ECU. I'm assuming the stock harness needs to stay plugged into the stock ECU. What gets plugged into the MS3?

 

The Basic MS3 is not designed to run in parallel, and my recommendation is that you don't do it.

 

How are NB guys mounting the MS3 Basic? The zip tie approach doesn't seem like a reasonable expectation, and doesn't allow the DB37 connector to be used.

Rev doesn't seem to be answering PM's at this time.

The only viable answer I can find is to make an extension harness ad put it on the passenger side. Doesn't this defeat the purpose of having a plug and play system if you need an external harness? Doesn't the first line in the MS3 Basic description state no cutting or splicing?

That looks like a great option, does it allow access to the DB37?

 

That bracket looks nice, though I don't remember my MS3 having any mounting holes. Zipties worked fine for me in my '99, and I was able to leave the DB37 connected, without even needing to get a right-angle connector as I'd read I might have to.

Ah, nice. I've since sold my Miata, but I'm glad there's a proper bracket available now. Zip ties may have worked OK, but I certainly wished I could have mounted my $1000 ECU in a more professional-looking way. Glad that's an option for people now.

 

My bracket comes in tomorrow. I am hoping it works well for my MS3x.

<p></p><p>From the Singular website:&nbsp; &quot;For those with REVERENT-built ECUs, a small pair of adapter tabs are necessary to fit the ECU to this bracket.
