MS3v3 System for CNP and EFI/Turbo "Beetle"

[kangaboy]

Well, I went ahead and chopped out a little chunk of the wheel well to fit the downpipe. It fits great now, and with a little grinding and smoothing, I'll try and make it look like it wasn't a hack job.



I got my intake tacked together, and then finished welding and painting it this weekend. These are just a few pics of the tack job. 1.75" piping mated to a custom .25" flange for the Hyundai throttle body.





I got a bunch of silicone joints and bends from SiliconeIntakes.com, and got those all mocked up as well. This will not be the final fitment location for everything, as I'm trying to get it all under the decklid while closed. I did a few more measurements, and with another 45* bend at the bottom, I should be able to swing the 180* stainless piece a bit farther towards the fan shroud, which will allow the deck lid to close. Just waiting for the next shipment of parts to come in to verify that.



Next was the full flow and the oil feed lines. After a bit more research, I went into the hydraulic store knowing what I was looking for. I got the 3/8" pipethread adapter to JIC/AN -8, and then a few 90* push loc fittings to get to the case. The case was easier, as they just had a 3/8" pipe thread to push loc fittings.





Lastly was the oil feed to the turbo. I went with a 1/8" pipe thread from my 1/8" npt brass tee from the oil pressure port, to a 1/8" to -4AN adapter, to my 12mm banjo fitting on the turbo. So with that said, I have a 1/4" feed line to my turbo.

nice! do they sell a 3/8 to push on fitting? i've looked for one in the UK

I pulled the motor this weekend to get some stuff taken care of in the bay and on the backside of the fan shroud. I plan on getting the fuel lines taken care of, mount the fuel pressure regulator, and get the breast plate tin fitted while its out.
I got another shipment of stuff from siliconeintakes.com, and got the charge pipe all fitted nice and snug. With this arrangement, I should be able to close the decklid with plenty of clearance.



The coil mounting nightmare has been bothering me for weeks now. They are kinda big, awkward, and there is no easy way/place to mount them. I opted to make a little bracket out of some steel and threaded rods. They look ok, and as far as I'm concerned, it's function over fashion. I mounted them with some grade 8 hardware, and loc-tite on the threaded rod/nut sections, so I hope they hold for a while. I just tried to mount them in an area with easy access, but were out of the way.



To answer your question, Andy, yes, I just have two 1/2" barbed to 3/8 threaded fittings in my case. Ill try to get a picture for you. I also looked online so I could give you a link, but for some reason I'm having trouble finding it.

Does that work with the push fit hose? No clamps kind? Thanks buddy!

Mounting all the efi and keeping it looking nice isn't as easy at it first seems eh

[kangaboy]

I believe this is it. And yes, its just a Push-Loc fitting with no hose clamps required. I also believe you have to have the correct Push-Loc hose for it to work correctly, but don't quote me on it.

I am currently trying to source a couple pieces for my oil drain line. The port on the turbo drain is 7/8", but I am having quite a bit of trouble finding hose and a brass fitting to put on my deep sump. Does anyone have any suggestions on where to find something line this? My local hydraulic store doesn't have them, and even my internet searches have come up short.

[kangaboy]

Alright everyone, I have all the motor parts lined out and hooked up. Drain line, oil lines, wiring, etc. Just waiting for the POR-15 to cure so I can actually fire this thing up.
I was going through the MSExtra walk through, testing my injectors, coils, fuel pump, etc. Everything went great until the Crank Signal test. I have no signal. I know the MS is functioning, because it recognized the RPM when I was messing with the JimStim on the bench. But now I'm not getting anything on TunerStudio when testing it in the car while cranking. Any initial settings I need to have adjusted? Its the CBPerformance crank trigger and 36-1 missing tooth wheel.

I read through a bit of material last night, and the two most common problems I could find were having the wiring backwards on the sensor, and not having the pots turned the correct way. Well I switched the wires last night and cranked it over again to no avail. It says there is no connection to the controller.
After work today, I'll open up the MS unit and ensure that I have the required jumpers, and the pot are turned the right way. I have read several threads where Piledriver has slapped a few wrists for using the MegaManuals, but I am sure that I have been using the MSExtra manuals for my whole build, so I shouldn't have an issues there.
If anyone has any other suggestions, please throw them out...otherwise, I will just update after I open the unit and turn some pots.

Edit: After reading more, I have a little question...I have a the DIY premade wire loom. So for the VR sensor, I have a white, a black, and a bare wire all wrapped in shielding. I have the black and the white wire going to the VR sensor, but don't have the ground wire grounded anywhere. I didn't know that had to be grounded, but I guess I will add that to the list of things to do this evening? Is this already grounded at the db37 connection?

[kangaboy]

You guys are really making me dig deep for this stuff, but I figured it out. For some reason i followed the cam toothed wheel instructions instead of just the instructions for the crank toothed wheel and VR sensor in the MSExtra, and didn't have JP7 jumpered on the MS3X card. Jumpered that puppy and put everything back together. We have a crank signal!
Now just poking around and cleaning up loose ends on the rest of the car waiting for my gas tank to cure.

Is there an echo in here? HELLLOOOO!!!

[Clonebug]

Sorry there Kanga.....but I don't know anything about the MS3 or cnp so I can't comment.
I make Mario do the hard stuff and I just plug and play....

[kangaboy]

Haha, no worries Clone, I was just having a joke. I'm just super happy I found a random thread on the Megasquirt forums that touched on the same issue I had.

Tuning to commence on Friday...I'm excited.

[risk]

Awesome! Let me offer some advice on tuning if I may..

Go EASY and tune it SLOW.. do not be temped to get it up on boost immediately, if you hear any pinging at all get off the gas, richen your table in that area and start again. Don't expect the autotune feature to react quickly enough to get it right under boost, it won't.. If you want to autotune, use it for the off boost areas of your fuel table, it works really well.. IF you use it for the areas of your table under boost, (above 100kpa) then make damn sure you are rich in those areas and it will pull fuel until it reaches your target AFR.

It's best to start out rich and work your way toward your target tune.. lean mixtures+boost=detonation, this breaks stuff.. a lot. Start out with a conservative spark table.. Once you have the fuel table close, and the car drives well, then start fine tuning the spark table.

Just my 2 cents.

[kangaboy]

Appreciate it Risk. I have no idea what to expect going in to this, so every little bit helps. I have been watching some YouTube and reading some threads, but getting the hands on experience will prolly change all that. Slow and steady wins the race.

[kangaboy]

Didn't get to the tuning like I had hoped...big surprise.
I did get the gas tank installed and hooked up though.
So I went to check my initial timing prior to firing the motor up for the first time with all the new stuff, and I got no spark. Come to find out, none of my coils were firing because I had them wired backwards. I didn't allow myself any time to work it after I found the fault, but I did quickly rewire two of LS2 coils, just to see if that is what was causing my no spark issue. So after rewiring two of them and testing again through tuner studio, I still don't have a spark. I'm using some vanagon plug wires and some cheap ass plugs, and I have been reading about the need for resistor plugs or wires, so I'm assuming that is what the issue is now. I can hear the coil clicking softly after the rewire, so I assume it is firing, but I'm not getting anything at the plug.

[Chip Birks]

Definitely use resistor plugs. You will hate life until you do.
