Lighter = Faster (N/A build thread #2)

I'm not sure how to embed videos from Google Photos. Does this link work: https://photos.google.com/share/AF1Q...I3akVubllYdE1R?

Sorry for the noise. The fan had just kicked on. It's idling around 1000 RPM. Anything less and it gets a little rough/unstable. It's quieter than I expected, but I haven't taken it much over 3500 RPM or about 10% throttle. Tuning is turning out to be difficult. No-load idle is pretty much sorted out to 4000 RPM. Tuning under load on the road is painful. Going from no load to load is requiring a massive increase in fuel due to the large changes in incoming air volume associated with small throttle movements. I assume this is handled by transient throttle adjustments but I read not to mess with that until the base fuel map is sorted. This would be much easier on a dyno. Any advice is welcome!

This is super exciting. But no the link doesn't work.

I can get the car to start, idle, and rev freely up to 4000 RPM. I'm sure it can go higher but I'm hesitant with the engine not broken in. Transient throttle situations and anything with more than 10% load is causing lean situations that cause the car to die. I literally can't drive it out of my driveway at this point, which is beyond frustrating. Unfortunately, it looks like I'm dead in the water until I can find some assistance because this is beyond me.

How experienced are you with tuning? That is something that I have always wanted to know more about but I haven't been willing to dedicate the time to it. That's really the most intimidating thing to me about starting from scratch.

Not very. Most of my experience is with piggy-back units in piston-engined cars. Just altering fuel and timing to improve power at partial and wide-open throttle. I don't have any experience starting from scratch. I've relied heavily on Chris at Ludwig Motorsports and Brian (TitaniumTT) just to get where I am now.

New kid takes time away from working on the car. I managed to get a couple things done this week while off of work:

-Changed oil and filter. Went with 10W40 weight this time and I'm still seeing 40+ psi of oil pressure at idle.
-Moved my vacuum manifold to the top of the intake manifold. The previous location allowed residual premix to pool in the vacuum manifold.
-Added a 1 bar MAP sensor to give me the option to tune with speed-density.
-Added 6 more oz of premix to bring the ration closer to 1.5 oz to 1 gal fuel during break-in.

The last one really messed with my tune, I think. What worked before was now running very lean so I had to add a bunch of fuel back. I've got it running again but I haven't got it out on the road yet. Hopefully I'll get a chance this weekend.

I've also ordered a FFE primary fuel rail and two ID725 injectors. I think relying on two ID1000 injectors in what are essentially secondary injector positions is going to prevent the car from running smoothly. Hopefully running smaller injectors in the stock primary location will smooth out idle and part throttle conditions. Vacuum sits around -6 psi at idle but peaks around -10 psi revving the engine in neutral below 3000 RPM. Hopefully this is enough to use speed-density tuning.

Lastly, and not sure if this'll work, but here are the latest pictures:

Trying something new. Maybe this worked.

TinyURL redirect to Google Photos?
It looks like your Google Photos account isn't set to public viewing...

Tried Google's own url-shortener this time. The issue is the album IS set up for sharing but Google has apparently done-away with the ability to embed images. They would rather the system only work through links and invites. It seems like whatever work-around I find is only temporarily. For example, I tried TinyURL over the weekend and I was able to view the pictures when viewing this site incognito. I checked again this morning and they were "x's." Even the album link: https://goo.gl/photos/6cLWLXYDxTRiWYtG6 doesn't work for everyone.

Google has really made it hard to link to photo on their site. First the removed
the image extension (.jpeg, ,gif etc) so sites like this would automatically imbed
them as images. The they did more stuff with the urls that prevents them
from being used reliably as you have found. I'm ready to move all my pics
somewhere else at this point. The only problem is how to update all the threads
from the past if you move and delete or do you just leave the existing.

Anyway, fuck google!

FC Zach · 09-18-2017, 05:42 PM

I use Flickr, no complaints there.

Yep, that's pretty much the conclusion I've drawn. The only convenient thing about Google photos is I have it set to automatically sync with my phone. So any pictures I take with my phone are automatically added to Google Photos and all I need to do is arrange them into albums. This is the only benefit over Picasa, which is what I originally used.

Do any of the other image hosting sites allow bulk uploading? Google Photos allows you to bulk download, so transferring pictures to be embedded online wouldn't be too difficult. The main issue I see is lack of available storage. That's another benefit of Google...

Regarding the car... I managed to put a whopping 7 miles on it last night. That doesn't sound like much but it's the most I've actually driven it to date. Even got it up to 50 mph and through all 5 gears. It needs an alignment badly. Part throttle acceleration is good, cruise is okay, transient throttle, coming to stop and starting from a stop needs help. It'll stall if I close the throttle and disengage the clutch too quickly when coming to a stop. For whatever reason it goes super lean when starting from a stop.

So I created a Youtube channel to embed videos, but apparently this site doesn't allow that either. Best I can do is share links:
