Alright, so, tuning is new to me. In fact everything about electronics on a car is new to me besides replacing sensors or pigtails, so forgive me for my ignorance.
In October I got a quote for an MS2 from diyautotune. The guy I spoke with was adamant about me getting the MS3 but that a little pricey. So I went with the MS2 instead. He walked me thru what I would need and and ways to help it be sorta future proof. Right now, I'm running on the OEM wasted spark with a single coil pack but eventually I do want to get COP. So he told me to have the logic level ignition put into the MS2. So, I did.
I had this thing built for me because I don't really know much about wiring up a board and I don't really have the time to learn how. So I get the ms2, I used the 8 foot harness and wired everything up, I ran into a few problems at first. my injectors I had a loose contact, and on my crank I had a bad crimp. Both of those are fixed. I tested the injectors, and I get a crank reading.
So to the issue, with the generic diagram that is sent with the MS2, it states that pin 36 is spark output 1. And diyautotune states on their forum that pin 6 will be output 2. So that is how I wired it. T/O to spark 2/3 and BR to spark 1/4. Off the db37
At this point I did not think about needing an ignitor. And I'm still a little iffy on if I need one or not. Everything works , and reads fine. But I'm not getting any spark at all. I pulled every plug and tested them against the block, and I even blew them out and made sure that they weren't flooded. Then I tested my connections to the pack. And I'm not getting anything from the signal wires. Just the 12v power wire.
I did some research and found on the msextra manuals that the QuadSpark can be used to power a coil pack. I wired that up, ground the Quad spark, then the 2 spark outputs into the Quad spark and then the Quad spark to the coil pack, still nothing.
Then I pulled my ms2 apart and realized that I have the logic level upgrade. After a bit of research I learned that logic level is usually sent out of the DB15. I traced the wires down on the bottom of the board and figured out they were to pins 1-4 on the connector. I wired the connection on the back of my DB15 (my first time soldering something so small) plugged it in and I have one line with 5v signal out of 4.
I'm not sure if or what I'm suppose to get from a spark signal out of the board. And I'm so afraid of popping a resistor. I'm not sure if I'm just not wiring things right, or if I don't actually have the right outputs.
I've tested with tunerstudio set to wastedspark, on d14 And on js10.
I guess I'm not really sure where to start at rhw board to verify it's even built correctly. Any help at all would be appreciated.
Thank you
