Well, did a lot of work on my truck the last day..
Part 1: Hydroboost unit installed.. waay better brakes after I fixed a Homer moment of mine and put the PS pump relief valve O ring in the wrong groove, making it bypass at about 20 PSI.. that caused some cussin'!

Part 2: Upgraded my fuel system, 1/2" fuel lines all the way with a draw straw.. My fuel pressure issue was caused by excessive goop on the tank screens (it was disgusting).. but the upgrade is nice anyhow!  WAAY better power, even though I'm still on my 4x013 injectors.. When the 5x014's go in I'm sure it'll be sweet.

Part 3: New TPS sensor, old one was glitching all the time.. and a little bit of programming... Freerevving the truck I build 20PSI boost and it sounds just ANGRY when the turbo opens up.. I've also incorporated some anti-surge programming into it to hold the turbo open more during shifts and force it open when I'm approaching surge.

I need to adjust my anti bark function now that I have the 7x .012's as it is way easy to bark the turbo now lol

7x12's seem to be nearly identical in cross-sectional area to my 5x14's  (1583 vs 1539 square thousandths of an inch, 4x13's I have in now are 1063)

I'm hoping to get the intercooler installed tonight, but might wait on it a little yet...

What I did for anti-bark is have map of turbine speed vs minimum turbo area, I also have a little idiot light that lights when it's actively increasing turbo size.. Since I have a TPS on my truck, it also increases turbo size for a certain duration when you let off the throttle depending on how fast you let off.. seems effective so far.. I only have had one small bark on it and I haven't fine tuned it

I dont have barking if I let off at the top of the map, but I do have it if I let up in the 5-10 psi range with shaft speeds in the 70k rpm range.

Spent the day cleaning up deprecated code and tidying things up a little.. and fixing some broken stuff, added some features, etc.
For some weird reason my LCD takes 45ms to update AGAIN.. I had it down to 19ms a while back and have no idea what happened.. I had to split the update into a few segments to make stuff run smoothly again.

I don't think a bit of surge at 70K is very damaging.. at 120K it has about 3.5x the energy

Another electrical gremlin I have is a sketchy RPM input.. it's picking up electrical interference so I'll have to look at all my wiring and maybe install some filters

If you need it to design a mount or actuator, I can give you good measurements, etc and it'll be cheaper than mailing it!
Doing it over again, or if this one dies too, I think I'd look adapting a much more common GM or Ford style to it that you can pick up easily and cheaply

I totally brain farted about sending the TPS off last week, I was halfway into town when I remembered.


Meanwhile, I'm working on cleaning up some wiring by setting up an I/O box near the turbo, it'll have 2 thermocouple amps (Just the Max31855's this time), and will read EGP, MAP, and engine RPM.. don't think I'll do turbo RPM though on that one though since I'm doing on soldered breadboard and it just takes too many components.. I've discovered something meanwhile.. I HATE BREADBOARD!!!
All things considered it's turning out OK, I'm using a Arduino Pro Mini 5V/16mhz which has a small enough footprint, the enclosure is a waterproof   ~2.5"x3.5" unit which should do fine.. I'll put a power LED on it and perhaps a CAN transmit LED as well so I can troubleshoot it at a glance.. Most components will be removable on headers for easy replacement and screw terminal connecting.. I'll post pics when I'm a little further along.

I got most of it done, doing some programming now and having issues with the thermocouple libraries giving me wonky numbers... It was a bit of an art form to get everything to fit into that box.. Still have to figure out how I'm going to run my analog signals into it and wire it.  I should have found a box 1 size bigger for this!.. Of course it wouldn't have been a problem if I used a printed board.

As far as programming goes, I'm going to try to keep everything in the daughter-boxes interrupt-only... If I can get a turbine speed input stuffed into the box I may put a "dumb" VGT position controller into it if it has seen that the turbo is about to timeout from not having received a command in some time just to keep it driveable if comms fail from one box to the other.  It's interesting to find other ways of doing things!

I just put my 5x014 injector nozzles in.. Also cleaned out my fuel filter prescreen (Goopy), and deleted the heater.. Sure made the shop smoky in a hurry.. Hopefully I see another improvement in the fuel pressure.. look forward to the trip to town tomorrow.. perhaps I gain 50hp with this..

I'm feeling lazy, but have to get to it soon.. have to replace E brake cables, with the cold wet weather they're freezing up on me...
Also ordered up some new headlights, hoping they'll be here today...

As for my plans on using the MAX31855 chips, a lot of the Ebay breakout boards are defective, with the GND and T+ terminals being shorted.. MAX31855's are also not 5V tolerant on the CS line, which makes them a pain.. I have gone blue in the face trying to get them to work and it just ain't happening.  Probably going to go back to the quad 31856 board I have.
