I do have valves in the exhaust to hopefully quite lower power.....like under 250-300hp, i need to hook them up. Its loud. I ran over the the gas station and picked up a neighbor(ish) who wanted a ride, "you said you were on your way and I heard something on 82 and thought it can't be him I'm hearing from way over there? Then it was on my road and them my driveway". I really should make it quieter.....he loved the ride though.

I'm back to having no faith in my O2 readings. I'm trying to use the ECUs internal controller....and 1 might be right but they don't match and I had trouble with channel 2 when I was setting it up so I kind of assume that is the wrong one....not sure though. I'm thinking its time to look at some plugs and to order at least 1 external controller, preferably 2 but budget.

Today I tried to get a log but the laptop shut down for whatever reason just after I pulled out of the development and before I put my foot into it to get some higher throttle/MAP data. Cold start and drive it was crisp and nice, but by the time I got home and things were pretty warm it just wasn't .... sure would be nice to have the log even if I don't trust the O2 numbers, at least I'd know what direction they moved. I thought I noticed this yesterday and today I'm certain.

I should get the USB log setup too. When the laptop is plugged it it logs anything I have a plot setup for because the PC memory is big, on a usb stick I'll need to be a bit more picky and but would be better than a laptop top the usually works fine.

And I need to sort what ever is going on with the column switches....right turn signal gets me horn, lifting up on the steering wheel gets me horn.

The oil leaks is an issue.....oil appears to be getting onto the axle maybe and is being thrown onto the rear header so it smokes and that is embarrassing. So I need to find and fix the leak.... or add a heat (aka oil) shield to keep it off the exhaust.

I did a kind of rough TB sync the other day and they are pretty good but the rear bank is different from the front and I can't reach that adjuster with the passenger side air duct in place. I need to pop that off and sort the sync. By 15-20% throttle the error is pretty much gone but I'd like it fixed.

Quite a punch list.

On the plus side it started nice cold again today. Then it start nice hot at the gas station twice because there was a line, only 2 pumps. I am so scared of heading out and then it not starting but it was fine. Leaving the gas station my neighbor called my attention to the the guys at the small shop across the street kind of looking in confused disbelief....the sounds it made starting made them look over but the sounds/acceleration leaving caused a bit of a jaw-drop and stare moment.

There must be a lot of folks like me that have followed along through the entire adventure. Forum to forum. First, a big thanks for posting and allowing us to watch the progress and the bumps along the way. Although I am a Ferrari owner and degreed engineer, I cannot hold a candle to your abilities. I get some of it, but a lot goes over my head. But I have never stopped reading along. I like to think I have a "never give in attitude" but bow down to yours. Not sure I could have kept at it as long as you have. I know the end is still not here. You won't stop until it is perfect. Congrats for your accomplishments. Will be with you to the end. Russ

So the project is old enough to vote this year! And in 3 more years, it can drink. Oh. Yeah. I guess it does already. Gas, for instance.

As much fun as it is to tease you once in a while, congratulations. It's been a long road and the results so far are just breathtaking. I don't think I'll ever read another story that's anything like this one, or nearly as fun to follow.

Well done Mark, from another guy who has been here from the beginning. I'll be kinda sad if this thing gets wrapped up completely - it is one of the most interesting threads on the net.

I will be waiting for the Lincoln powered hot rod!!

John

thanks for the kind words...I'm not even sure I remember what to do if the V12 isn't on the list.......


Where I am finding oil is confusing to me but I really suspect the oil feeds  to both heads are leaking.  That is a heads off repair so I will focus on remediation....because the engine isn't coming out and the heads are not coming off....I'm just not really clear about what the remediation looks like other than a wash every time it runs.

I am also learning wheel wells are important and I should have them because I'm finding the gravel they put on my road everywhere.  Something to add to the list.

while cleaning the oil I noticed the front 2-1 collector doesn't fit all the great to one of the headers and is almost certainly leaking air, which could(would) make O2 sensor read leans.  I'll try to seal it up with heat temp RTV and I did ordered 2 external WBO2 controllers

Crikey, have been following along since the second thread on Fchat. Now I feel old…

It does feel like an era is ending...at some point the pain of defeat begins to feel normal. As I said I was kind of dragging my feet on the intake port fixes to avoid more bad news....and I guess the oil leak is bad news as I'm almost certain its the pressure feed to the front head....but my goodness does is it a joy finally have it driving.

My plan for today is to get as much access to the corner of the head where the feed pin is and silicone the bajesus out of it. Its pressure oil so I don't think this will work but maybe. If it fail, the backup plan is silicone on a tube going to a catch can. The silicone will need a full day to dry so no driving today so after the silicone is on I'll get started on the rest of the punch list.

Actually found the oil leak and it way less than I was thinking....just a bad fitting that is hard to get to and impossible to see until the intake is off.

I got the coolant stuff back on and added a bottle of water wetter and 1 gal of green coolant and rust should now be in check and I have almost an extra 10F before boiling. Tomorrow I'll see what's up with the column switches while I wait for the oil fitting

It turned out setting up the USB drive logging so I don't need the laptop was trivial...just add a line to the model that says logging on so now if the USB stick is plugged in it should be records. It worked in the shop anyway. Not sure what happens if the stick is full, probably stops I suppose.

Its pretty capable:

Quote:
LOG_LoggingFrequency [Hz] - This is the user defined base logging frequency. This can range from 1-10000 depending on the number of channels being logged. The maximum bandwidth of a standard USB device is ~50,000 samples/second so the user should take some care to log at a reasonable rate. 20 channels at 1000Hz or 200 channels at 100Hz are generally considered reasonable depending on the device.


I turned on about 15 channel at the default 20hz for now.

The cluster switches were also pretty straight forward to correct. One issue was I assembled it with the front bit that rotates with the steering wheel clocked wrong, that should fit the turn signals. And the headlight switch was missing a piece, don't know how I didn't see it before, but I made a new one from a nylon body clip thing and the lights work again....I wondered why it was so sloppy, now it click on/off nicely.

I noticed the slow down and brake lights that are supposed to be malfunction and shift respectively were always lit. There was a typo in 1 of the malfunction conditions so that should be fixed now. And the shift light stuff it looks like I planned to add it and wired the light but never added the function to the ecu so that is also fixed I believe.

During the 9k burnout you can hear the engine bouncing off the rev limiter, the only problem is I realized I have a soft limit set so there should be no bouncing on anything. In the log I posted you can see the throttle opening and closing, that is what caused the sound and should not have been happening. The best I can tell I tuned the throttle actuator on battery voltage, but running is higher voltage so it moves faster and my tuning values were too aggressive and allowed it be become unstable when I hit the throttle quick. I cut the tuning values by 20% which should fix it but I'll need to confirm when its running.
