Thanks!

Wheel speed is a VR sensor currently.  :)

Tested my front wheel speed sensor last night.   It reads now, which is a start!    Results are mixed but I need to work on it a bit more before I make any determination in function.   Might put a scope on it.    Readings were a little erratic.

I ran the car up to 6000 RPM and 10 psi.     Fueling was rich but it felt great and pulled hard!    Im working on dialing fuel in next and hopefully going to hit up a friend about some dyno time and supervised tuning (hes a pro so Id like him to kinda look over my work).

Cruise control parts should arrive today so hopefully I will work on that this weekend!

And apparently I totally forgot to post the pics of the new fuel system and dash/center console progress.

Center console work in progress.    The black plastic trim pot surround will be billet at some point when I stop being lazy and go get the new CNC computer finished and the HVAC controls need a bracket built, and the whole center console top needs refinished, BUT, it's functional anyway.





I don't know why the EXIF data turned one of those sideways, but I'm not feeling like fixing it, so turn your head, haha.

And fuel system!

A couple pictures.   First is my front wheel speed sensor setup.   It picks up on the bolts for the rotor hat (2 piece rotors).   It definitely probably works!



And next is my finished up extinguisher mount.  The "Haltech" tag is the pull tab for a ball spring locked pin that holds one end of a quick release and the other is a pocket that locks on a bolt.   So yank the Haltech tag then pull forward on the extinguisher, basically.    Looks nice and I can pull it free in just a few seconds.    Definitely better than nothing!

I will remember that on the drier!   I kept the old one (and sealed it up).   Ill dry it out and keep it as a spare.

So I've been slack the past week.   We hired a new guy at work, actually 2 new guys, and that and taekwondo have kept me busy.

Anyway, today I had nothing to do so I went out to take the car to cars and coffee and...   dead battery.   Apparently I have a draw somewhere.    The only thing I know of that should be on with the key off is my power door lock controller and that shouldn't be killing the battery, so I'll have to look into this.    The only other new thing in the chassis is the MSD pump booster so I'll check and see if that's drawing power even when the signal wire is off.     The car sat for about 2.5 weeks between drives, so it certainly shouldn't have been dead.

I put it on the charger and it seems fine now.   I have the fancy pants Optima charger for my fancy pants Optima battery.

Today's list of things to look at were:

Build fire extinguisher mount
Fix AC wiring so that the ECU controls it properly.
Replace AC drier
Replace AC expansion valve
Fix front wheel speed sensor (if time allows)

Results:

Extinguisher MOUNT is done, but I need a couple clamps to lock the extinguisher itself to the quick release bracket.    I'm happy with the how it came out, it's very snug to the passenger seat but I can get it free in about 3 seconds if need be (grab pull tab, pull on it, then yank and it's in your hand).

AC wiring was two fold:   1.  I was trying to run it off the ECU directly for compressor control.   After more reading, I decided to add a relay.   Luckily my fan fuse block sits next to the compressor and had an open location so I didn't have to do too much, just make a harness that plugs in between the trinary switch and the main harness that drops a relay in between.   Done.    Did that fix it? Nope, because (item 2) I had chosen the wrong output on the ECU.    Fixed that and BOOM, compressor works properly as commanded.

AC drier replacement was easy, two t bolt clamps that hold it to my bracket I built, and two lines and swap.  Done.

AC expansion valve is luckily easy reachable but still not super fun to do as it's snug in that area under the dash.   Especially where the little "sense" tube goes.   So, that is done also.

Good news on both of those is that the new ones are in.  Bad news is I couldn't find anything wrong with the old ones (well the drier was toast because it was open to atmosphere for like 1.5 years).   I did validate that the system can flow air both directions though, so we'll refill it and retest.

Front vehicle speed sensor.    Well this was easy.  I had selected the wrong drop down for sensor input.   LOL.    Fixed it, but haven't had a chance to test it yet (will do it tomorrow morning) but I'm pretty confident that was the issue.

Next up:

Cruise Control
Find out if AC finally works
Torque sensing electric power steering upgrade
Fix knock sensors (still a big WTF on this one)
E85 Tune
Add Boost
Figure out how to install my front sway bar without impacting turning radius
Finish center console

Id hit it lightly with a gray scotch brite then wax/grease remove it.

AC parts came in, I'm going to try and get them put in one night this week and hopefully try and get AC working this weekend.   That'd be nice because it's HOT here!

I also ordered my cruise control stalk.  Once that gets here I'll sort out how it's setup and build a resistor array for it so that I can use 2x wires to run it.   Then I should just be able to program the Haltech for it and have cruise!    Next up after that electrically is updating my electric power steering to a controller with torque sensing so that it's less annoying, as well as sorting out my front wheel speed sensor that isn't sensing front wheel speed (YOU HAD ONE JOB!).

Yeah, I saw that at PRI last year.     Id have gotten one but I needed parts earlier than late June.   :(

Im happy with my setup thus far though.

I have a cable parking brake now with a in-the-hat drum setup on it.    It works fine but it's not something you'd use to hold the car at the drag strip.     You'd want a hydraulic setup for that, like a drift brake.   My parking brake is dialed in but I can definitely over-whelm if it I really try to.

FWIW (since we're full squirrel) I'm considering something like the Tesla setup (I had previously looked at an electronic actuator that does the handle job, but the Tesla setup is cleaner) and then putting a drift brake hydraulic handle with an inline master on the rear calipers.   Then I have a parking brake for parking and a hydraulic over-ride for the rears in case I need it.   I feel like that gets every feature possible, and using an electronic setup means I keep a "real" parking brake without needing 2x levers.

Okay, definitely probably done meandering about...

So, tried to get AC going and had 3 issues.

1.  Compressor wires were flipped and it's apparently got a diode in it, so it wasn't turning on the clutch.   Flipped those and it worked after...
2.  ECU sense signal for the AC isn't working.   This worked when I wired it, so I need to dig into this a little.    We bypassed it for testing.
3.  Even bypassed, my ECU wasn't triggering ground for the sensor.   I likely grabbed the wrong wire for this in the 4 pin connector (I only use 2 of the wires at the trinary switch).   We bypassed this also.
4.  AC held vacuum great and took refrigerant fine, but we didn't get any flow in the system when the compressor engaged, instead we saw vacuum on the low side and pressure on high, which would indicate that the system is not flowing refrigerant properly.

I'm going to:

1.  Test the wiring lead that runs to the ECU from the AC system and see why it's not working properly.   I may have just failed to plug that wire back in...
2.  Same with the ECU trigger output.   I'll see why that's not working the way it should.
3.  I ordered a new drier (i needed one anyway) and a new expansion valve (probably the issue).   When those come in, I'll pull them both out and check flow through the rest of the system with air and make sure nothing else is blocking flow.   ASSuming the rest of it's good, I'll swap in the new parts and triple check wiring, then go try to turn up the system again.

At least I have a good friend of mine that has a machine, so we can fill/recover it and it just costs time to test.   I'm optimistic at least that it held vacuum well and other than whatever is blocking it up, it at least tried to work.   I'll figure out the electrical stuff shortly and it should be good to go once that's done.

I'd not seen those parking brakes from the Teslas...   a little reading says it's just run with an H-Bridge like a power window motor.   So either 2 relays/caliper or a dual h-bridge, like a Pololu dual motor driver.   You could even current sense drive it with a little Arduino box.    Verrrrrrrrry interesting, I could simply my center console with an electric parking brake...

Sorry. squirrel.

So, a quick tuning update.   I'm working on fine details in the software now, so here's a few notes:

1.  The auto-tune tables were laid out really weird.   Thus they weren't really learning heavily in the drivability regions.    I reconfigured them to concentrate on drivability zones and I'll retest them to see if they're a little more useful now.    Just trying to tighten up a few rich/lean spots.
2.  Working on getting transient "tip in" fueling right.   It has a tiny bit of a lean hit there, so I'm slowly cleaning that up.
3.  My driver side intake cam control is still "meh" at low engine temperatures, so I'm adding a little more duty cycle authority to those areas to try and clean it up.   Right now it will bounce around far too much as the duty cycle base seems to be too low and the PID (mostly the P) is too aggressive.   Once I get the base duty cycle closer, I'll tune the PID a little, but I want to get both banks looking similar on base duty cycle before I alter PID.    Passenger cam is fine and the exhaust cams are fine.   Once temp comes up the ECU table has more duty cycle anyway, and seems to be fine.
4.  I'm starting work on my boost control tables.   Now that the tune is getting closer I need to get out to Mexico and do a few test hits to see what boost curve looks like and make sure I'm building boost correctly and start getting solenoid duty cycle tables populated.
5.  I think I'm going to change the car over from the Rotella-T I've got in it to some Schaeffer's oil, which a friend I trust recommended.

Beyond that, I still need to figure out what's up with my wheel speed sensor, probably have to scope it to see why it's not behaving.   Oh, and I want to get started sorting out my front sway bar situation since I couldn't use the original location.   I just need to put it on the lift and figure out where to put it and make it happen, really.

Paint the jambs and inner areas of the doors/fenders, then assemble and spray the whole thing that way.
