Drove it again, somewhat less successfully, haha.

Took it Nick's (BeasTT) house, which is about 7-8 miles away on a big 4 lane surface street.  Car did fine though it bobbled pulling into his subdivision.    Didn't think much of it as it restarted fine and I stopped by his place for 5-10 minutes.   Went to leave and it fired up and... zero throttle control.  None.    He and his Dad helped me look at stuff, but nothing obvious came up, and the ECU was throwing DBW "tracking" errors, which means that actual throttle position didn't track requested position.   When it sees that, it just turns it off.   Poop.

After about 30 minutes of poking at it, we decided to limp it home at idle.   Nick followed me in his truck and I limped it home down the road.   Fun!    I got it home without overheating at least.     Did some diagnosis and it appears the issue is indeed the throttle body, so I ordered a new module for it (mine was lightly damaged in shipping originally, and apparently finally failed).

Beyond that I put the new injectors in and pressure tested the fuel system, all good there.    The throttle body sensor/controller should come in today, so hopefully I'll put that in tonight and validate that it's all fixed up and get back to tuning/finishing things.

That is one heck of an odyssey!   First Ronin shirt on the islands?  :D

Cars for sale / Re: looking to buy LS FC

I don't think another FC exists as nice as Charlie's (Bowtie7) and I've seen more of them than most people.     Wherever you end up, if you're looking for a car to drive, spending money on a good one will save you money over 18-24 months.

This is all very complicated.    I swear I will never again whine about 4x U-Haul trips across town.

That's not too bad.    It should be worth a little bit of protection.

No worries, I didn't take it that way.    The next set of tires will be a little shorter and it'll help all around I think.

In fun news, I drove it (properly) yesterday.   The last two drives were around my cul de sac and accounted for ~400 yards.   This time I took it out of the sub division onto the surface streets and up to around 55 MPH (it is plated/insured now).

Thoughts/issues:

1.   Steering is WAY too slow.   I think this is the 20:1 manual rack.   They make a 15:1, that's happening sometime in the near future.  It's annoying, like driving a bus right now.
2.   Manual brakes need a little getting used to.   I also need to tune the bias.  It stops fine, just a different feel, for sure.
3.   I adjusted the clutch for more throw as the carpet took up a lot of it.   MUCH better now and I can (mostly) drive it without sounding like I've never driven a stick shift before (revving and clunking).
4.   Alignment/suspension setup is fairly ok.   Didn't pull or make bad noises, doesn't seem to be rubbing anything, and felt fairly stable though I only drove in a mostly straight line.
5.   I have been trying to identify an issue with my wideband readings.    Turns out I had two.   First issue is when I took the suspension apart up front a couple weeks ago, I had to pull the turbo for clearance.   When I put it back, I didn't align the v band right and I had a nasty exhaust leak (I could also hear that).    Second issue (the more confusing) was that my widebands were flipped.   This is because #1 on the Ford is passenger front.   That's all well and good my coils and injectors are setup that way, but I wired the passenger side as bank 2 for wideband (because it damn well is) and the ECU was mapped that way.   I fixed that now, so my WBO2 readings will match the cylinders appropriately and now I know which sensor is where.
6.   I had a cylinder dropping out due to a bent pin in a coil connector.   Took apart the connector and fixed that.

All in all fairly successful.   I took it up to about 60 MPH, 3800 RPM and 40% throttle.   That hit around 106 kPa, which is TECHNICALLY boost.   I heard the turbos come on and the BOV released when I let off, so that was fun.   I don't have the injector top hats for my ID1050x pieces yet, so I can't actually hit any real boost (and the tune needs babysat/worked), but it was fun to give it a little gas.   I ran it up to 6th gear to prove out the transmission also.    There were no vibrations in the drivetrain that I felt, so my angles must be at least in the ballpark (I did measure them, just nice to sanity check under load).    The Detroit locker is a little noisy in corners, but it's not terrible.   I need to run the exhaust out the back, it's boomy inside the car.   I'm very lightly considering an exit in front of the rear wheels like a 70s Trans Am racecar.   Maybe.   It will fit.   Haha

Next up is to body work the front bumper (just needs a tiny bit of work) and paint/dip it, then install.    That finishes the outside body work on it for now, other than polishing out a couple little spots.    Interior wise I need to hook up HVAC ducting and design/build mounts for the vents.   Then finish the parking brake boot and install the center console lid and arm rest.    I still need to finish modifying the rear package tray for seatbelts and installing those as well, then it's mostly headliner and rear seat (someday...   dang upholstery shop jail) and she's mostly put together and ready for tuning/breaking shit/fixing it.

edit:  Oh, and I fabricated a breather tank.   I need to buy some hoses and fittings for the valve covers and then plumb it up properly.   It came out pretty well.

You'll want ABS for anything that has strain/load on it, FWIW.   PLA will have issues with interior temperatures and glassing temp.

I've printed lots of brackets and such.   Mostly ABS/PETG.

General Tech / Re: LS Swap into FC Mount question
« on: April 17, 2019, 09:31:20 PM »
Hinson FC mounts are a PITA to install.    I've used all of them.   I helped prototype the mounts that became Ronin.   I changed my Granny's kit to them, they were that much better.

Hinsons are harder to get fitted up, require more expensive motor mounts and are less adjustable (and get in the way more).

I prefer Granny's to Hinson, but Ronin by an order of magnitude over both.  Go Ronin.

I really do like the way the tires/wheels look, I feel like it fits the car's style, it just needs to fit the damned fenders, haha.

My wheels are split offset, I have 2x 17x9 +20 and 2x 17x9 +35.   I had them with the +20s up front, I just swapped those to the rear and validated it doesn't hit by "flexing out" the rear like a rock crawler and validating clearance.    The +35s up front tuck in a little more than I'd like, but it's not a hella flush car and I care more about not jacking my fenders with the tires than I do being dead flush, so it'll work.   It's fairly even front/rear as well, though the tops up front obviously camber in more than the 0* camber straight axle out back.    I'm going to drive around a bit and make sure it clears now, and then do some testing to see if she can come down some as I think I might be able to drop it a 1" - 1.5" now, which would suit my taste a bit better.

I did catch my fender pulling out of the driveway (whoops) which is what prompted me to try flipping front/rear.   It didn't hurt anything really, it scuffed the paint under the fender (touched that up already, it's under so you can't see it anyway) and cracked a bracket on the back of the front lower valance.   Turns out that bracket was installed half-ass during manufacture anyway, so I glued it on properly and used that as an excuse to fix the alignment it a little as it had some preload against it.

I also fabricated a little aluminum bracket that holds the fender out in front of the wheel so that it can't blow around in the wind at speed (before it was just the shape of the fender holding it, and the fiberglass valance).    It's 3/8 solid rod with 1/8" plate brackets, so it's pretty stout.   I'll build a twin for the other side shortly.    Beyond that I've been modifying wiper arm parts to fill the holes where they go in the cowl so it doesn't leak water inside the car.   I don't have wipers right now and probably won't until next winter when I get around to figuring out how to fit them, so I'm hacking up stock parts to plug the holes and then putting plastic plugs in the cowl on the outside to fill where they'd pop out.   I think I'll be fine with Rain-X for now.    I also need to seal the passenger side fresh air vent in the cowl/interior (driver's side is done) and get the HVAC ducts run and temporarily wired up.

The passenger seat is now in as well;   next interior task will be fitting the center console lid somewhat more permanently, and getting the rear package tray upholstery finished/seat belts installed.   I'm hoping to get the front bumper painted/installed shortly as well (just satin black plastidip once I spend an hour or two finishing the final body work on it).

Bit by bit...

FWIW, I ran race bullets into a typical fart cannon and it actually mellowed the sound out a LOT.    I'm planning to do race bullets (already have them) to chambered mufflers on the Mustang for a more low tone.
