I purchased one of the enhanced MS2/DIYPNP from Brain and Rev during this group buy:

https://www.miataturbo.net/ms-labs-miata-accessories-89/99-00-01-05-msm-megasquirt-ms2-diypnp-enhanced-group-buy-50791/

And I have the DB15 connector with these wires:



Red, Blue, Yellow, White, Purple, Grey, Brown and Green

I know that the LC-1 wires into the first 4 wires, but I'm wondering what I need to connect to the Purple, Grey, Brown and Green wires?

For reference, here's the DB15 excel spreadsheet for my unit:

1 12V YES
2 GND YES
3 SIGNAL GND YES
4 WIDEBAND YES
5 VREF (5V)
6 5V FOR DIY
7 SWITCH TABLES YES
8 FLEX FUEL
9 LAUNCH CONTROL
10 IGN C YES
11 IGN D YES
12 ANALOG KNOCK OUT
13 DIGITAL KNOCK IN
14 ALT MAP IN
15 RPM OUT/EBC OUT

I searched around through some of the relevant threads, but didn't find anything concrete; any help is greatly appreciated!

 

You don't need to connect them, they are optional. Just tape them away.

 

Awesome, thanks very much Rev!

 

Is there a pinout for this plug? Particularly for lc-1 connections as my wires are all black

 

If your DIYPNP was built by Braineack, you need to consult with him.

 

I would have wired it the same way, just without the color codes.

 

Braineack, could you tell me which pins on the connector connect to which of the wires on the 6-wire lc-1?

 

did I build you diypnp?

 

No but I was hoping the pin connections were universal, if they are I assume I follow the connection numbers above and match with the wideband instructions? Also, will I need to connect a jumper or anything on my pnp2 unit or just change the settings in megatune?

 

they arent, its however you populate the mainboard.

 

Wait, is this a DIYPNP or an MSPNP2?

 

It's a pnp2 straight from diy auto tune website. I just posted on here after getting tired of searching for info and getting nothing.

 

Have you thought of asking DIYAutotune?

Edit: you can't have looked very hard.... http://www.megasquirtpnp.com/maindocs.htm

 

I have asked them and I did look hard which is why I risked asking on this notoriously snippy forum

 

You say snipey, but you couldn't find what you were looking for in the manual for the ECU you bought, you deserve the sarcasm quite frankly.

I did 1 30 second google search and found what you wanted. Hardly difficult.

 

It wasn't in the manual. Hence why I asked on here AFTER emailing DIYautotune but I knew I had seen that picture online before and I was trying to find it for ages, all I came up with was the basic versions of the manual or that pinout with only 1 label on it from some random supra info. I knew it was there but I couldn't find it and I know it shouldn't have been so difficult which was frustrating so I don't deserve the sarcasm when I'm just asking for help. No need for the attitude when you could have just said this:
