I have never taken the dash out. I will have to try and find the engine wiring harnesses connector.

Both the other green and white and other black and white are not shorted.

Steve you rock! The coil positive has a full short in it. Haven’t found it yet.

I’m trying to track down a short in my 12v positive from my tach to my coil. I seem to have two black and white wires and a green a white in my coil bundle. Any ideas? The 2nd b/w and green/white doesn’t show up on any wiring diagrams. I have a 1/71 build.

Well I am a liar. My wiring was wrong. Iac wasn’t even working. But it lets by 20% air or so with 0 volts. So this is cold start with 20% air going by. On my haltech You can set voltage at a percentage of 0-12v. So roughly set the lowest voltage it can go to 33%. Should work, but to be determined. I need to run a new DPO wire

I will have to fix that little pinch. I like the stock style hoses. Adds some style to the hoses.

Sounding good! FullSizeRender.MOV

Finally getting somewhere with iac and cold starts. IMG_0256.MOV

Still finalizing it all. Currently won't start, so I am trying to figure that out. The iac is just a bosch.

Pretty darn cool.

ITB with IAC take 3. My last bmw IAC wouldn’t play nice with my haltech (basically it’s the opposite of how haltech controls it). This one let’s by a tiny bit of air at full closed. I plan to see if I can set the butterfly’s and it to play nicely and not idle too high when the engine is warmed up. Fingers crossed.

Whatever AF mixture I want. 35lbs can go up to like 500+ hp. Which I will never achieve.

I ended up getting new injectors. These are 35lb and they have a traditional 20 degree cone spray pattern. Prior I have a v pattern designed for DOHC motors. Squirting at two valves. Hopefully the work a little better. They are slightly longer. But I got them to work.

Well Tons if fiddling and swear words. I now have 100% throttle engagement from the gas pedal. Turns out prior I only had like 70%. I normally work from the engine bay and I could always get 100% from there. Whoops FullSizeRender.MOV

I am using a mid 80s bmw iac valve. I was having a hard time finding a hose that looked good and would hold the vac without collapsing. Then it dawned on me, maybe one meant for the same bmw. Fits awesome and is exactly the right size for my balance bar. Stoked

I bought the WB2. They updated the plugs and u shouldn’t have to de-pin it to get the plugs through the body. Which will be nice.

Yes Can Bus is what I meant.

My friend swapped my clutch and fixed some bugs. But putting my center console back in, he pinched a wire on the o2 sensor. Shorted and burnt my dual o2 can sensor up.

One of my issues so far with running is my injectors that fit nicely into the throttles are a V stream. So I believe they are just spraying on the walls. I am going to switch out to DeatschWerks 18U-00-0035-6. Single cone spray. They use the same connector. Hopefully I can get the correct orings to deal well. Tiogatold me to do this in the start. I should have listened.

With the Yen being so low, buying from Japan is awesome! Fujitsubo or similar can be had at a discount.

It will get checked again. Fingers crossed. It will go back to the machine shop to get decked again and re lap the valve seats. first it needs to go in a large ultra sonic tank.

Well sadly my ported E31 head was in an engine shop fire. Luckily my 3.1L was pretty far away from the flames. Well lots of elbow grease and 4 hours in my vapor blasting cabinet and it looks as good as new!. Now time to have it put back together.

I have a dyno tune session booked. But the tuner kind of rubs me the wrong way. I love unique things and a challenge. I also hated the black bodies of the Jenvy. The SK look rad. That being said I think I would pick borla if I started over.

In the IAC settings, you can turn on idle controlled via timing. I had that off. It seems to help. I have a noisy tps as well. Something I might try is grounding the shielding? Or I might re-run that wiring set. I would have to look at what plugs, but they are stock efi? Or something of that sort.
