Turns out that the 1/2" fuel/PCV line just jams perfectly into the breather port on the intake.

I'm not a big fan of the large print "OIL CATCH CAN", but for $25 I can't complain too much (I tried removing the print with various chemicals, but it resisted all of my efforts). I also need to reroute the vacuum lines better than the picture shows, but that's a different issue.

I was confused with how Id route it, this is picture is gold!

Here's a pic of the bracket I made:

You could probably mount it on the battery side as well. I've got other (car audio) stuff over there so that wasn't an option for me.

Re: Sam's 10:1 Motor Build 10/29 Miller Tuning

Post by LeiseyJr »

An update Miller WAR was installed like 2 weeks ago. Installed my dads tune for two weeks and car was running quite rich. On further investigation like 12.5 at part throttle. WOT was only decent map as well as the timing curves. The fuel maps all needed editing. So I popped fresh plugs in it, and the Innovate with a new sensor this weekend. Spent most of Sunday tuning, and all the maps are very solid now. Idle still needs minor meddling, part throttle needs to be cleaned up but it's now at 14.7 (and low 15's), dips into 13's p/t under load. At WOT 12.2-12.5. I am quite pleased with it. When I get ballsy enough I will maybe try some Alpina b10 timing values.

Finally doesn't foul plugs in traffic, torque is back and hopefully mileage will go up. It pulls super strong to redline now that it's not at 10.0 at WOT. I actually feel comfortable turning limiter up higher since it pulls all the way to 6400.

Reason why it still hasn't touched dyno is shop we knew has closed down, and no one else is open on weekends that I have seen yet.

I was still never happy with the idle. So I ripped it out and installed M1.3. It's running on the Alpina B10 tune with some minor tweaks. Not optimized fully at WOT, but idle is mint. You can also see ghetto catch can setup running to a gatorade bottle. Catch can remained empty so it has now been removed. It will be re installed at next track event though.

How's that innovative holding up for ya? I doubt I'll ever buy another, mine would eat 02 sensors for lunch.

I do ‘t hate it. But I should’ve bought a AEM.

I hears Angry Ass Solutions might be making an Alpina intake manifold for M30... Might be a good choice for this car if the price is right...

I will be curious to see if they are doing a direct copy or looking to improve the intake for better flow.

Switched back to M1.0 and Im so fucking happy. In the morning as soon as I hit key it starts, throttle response feels like I installed a MAF, and I was also having heavy oil burning after high rpm that shit is gone. It idles fine no stalling just not like silk. I will trade silk idle for driveability, engine is such a joy now.

It wasnt M1.3 fault that it had a stumble on tip in, it wasnt its fault that it was burning oil on decel, it wasnt its fault that heel toes were a pain because it just didnt want to rev up. That was my fault, the cookie cutter B10 tune was doing what my 061 B10 tune was doing. I shouldve expected that. I could’ve spent another 2 months tuning it. I elected just put in the old setup, Id already spent lots of hours on and I have more spare parts for.

Know that I switched back I realize how good my old tune due to how much time I put into it. Not to mention all my M1.0 stuff is brand new, CTS and reference sensors. Also the harness looks proper no exposed wires, and fits correctly. M1.3 relays didnt mount to fuse box and giant diagnostic connector was dangling.

Happy to report that Im finally very pleased with this engine now that its all broken in and is tuned right. Hope to get many miles out of it.

Nice build. Thanks for documenting your efforts.
Read about the oil in the intake issue and remembered this video:

Hope it helps.

Update.

Motor blew a headgaket awhile back due to bad radiator/bad temp gauge. Idling, A/C on, and Texas summer were not a good combo.

Now that I finally found a good radiator it is staying cool on track, like I remember when I first swapped the car. Colder operating temperature all around now. Still can get warm over 95 with a/c on, stays cold with it off. Original Equipment radiators ftw

Tune haven't really needed to touch. Still no dyno. Has beat a e36 m3 that dyno'd at 217whp and someone who tracks a sc400 has noted it pulls away from him now on the straights. Whereas before it didn't.

Car overfilled catch (keystone beer) can during this session:

So it's definitely not blow by, just over oiling of the head. Probably gonna just get a bigger catch can or a oil resistant sealant on that baffle for the breather.

15K miles so far.
