Advice on what to buy

[sashay33]

I am converting my VW street rail to EDIS and FI. and then adding turbo after I get those two systems up. My question is what do I need, from DIYAutoTune, to get up and running? I know I want to use MSII pcb3.0, but as far as extra cables, hardware, boards I am a little confused. I have the ability to build the system myself and will do so. I do not need the boost components, but want to be able to expand to accept.
Thanks in advance, Karl

Perhaps I should try to answer my own question and maybe someone will tell me what I need to add.

You can split things into four.
MS unit
EDIS hardware
MS loom
EDIS loom.

Part made MS looms usually make use of the MS relay board too. You can get some 'plug and play' looms for certain cars - but for most you'll need to adapt a part made one to your individual needs. Another possibility if your engine was ever made with EFI is to adapt a loom from that. Or you can make up one from scratch.

Most buy a complete used EDIS kit. This comes with the connectors cut off leaving pigtails. Get the correct colour and size cables to match what the maker used and make up a suitable loom for the positions of the EDIS bits you end up with.

It's well worth drawing out your individual circuit diagram before making or modifying a loom. Use the MS ones as a basis. Note the colours you use.
Makes fault finding down the line very much easier - unless you have an elephant's memory. ;-)

A stim is also essential, IMHO, if you're building the MS yourself. I also have a break out board which fits between MS and loom - makes any fault finding or checking voltages etc very much easier.

IMHO, you need to take as much care making up your looms as you do making the MS itself. Any bodging there will come back to haunt you. ;-)

Thanks for that info Dave, however I am still unclear on what "MS" products to buy. This is what is in my shopping cart right now
1. MSII pcb 3.0 kit
2. Lead bending tool
3. Stim and power supply

Are you saying I should use the breakout board and use relays and fuses where needed and not use the relay board. That sounds like what is best for me.

The breakout board is only used for test purposes. It's not essential, but can be useful if you have problems. When something arises - which it will - it's best to eliminate the simple things first like wiring connections.
Another way of putting it is the stim tests the MS without using your wiring loom. A breakout box and DVM can test the loom and sensors without using the MS.

As regards the relay board, if your car already has EFI, it will probably have a main and pump relay - or if it was an option on your model, the place to fit them. Which may be more convenient than finding a site for the relay board. If starting from scratch, the relay board is probably the best option, as it does simplify things. And you don't then need to solder your loom to a DB37 connector - which is probably the most difficult part of making your own loom.
