The car is out in the wild. Here it sits, after running under its own power for the first extended period in years:







Lots to do to get this thing fully dialed in, but before I go deep on that, a few impressions:
  • This car is truly daily drivable. Starts immediately and power is smooth everywhere.
  • AFRs are solid everywhere, although boost is currently spring limited to .4 - .5 BAR.
  • As a result, the car is REALLY FAST, almost scary fast for a guy used to 2L 911s. But there's A LOT left in there.
  • The Sachs BTR clutch is sublime.
  • Brakes = GREAT
  • The best handling 911 I own - I cannot believe how light the steering is.
  • Mid-year sport seats are the most comfortable seats Porsche ever made.

In terms of dialing things in:
  • Boost - either the car still has a boost leak, or there is something wrong with the stock gauge...or both. I wind it up to above 4 grand and boost tapers back to zero on the stock gauge. I'll have to data log with a passenger and laptop to confirm. Boost onset also seems really late (not seeing any boost until above 4K).
  • Speaking of boost and data logging, I will next bump peak boost via the ECU to .8 BAR. I have yet to confirm that the CPU controlled boost solenoid is operational.
  • Knock control - have yet to confirm if knock control is working. Again, a job for data logging.
  • Timing - I'm still running a very conservative timing curve. I'll start tweaking with this only after I have confirmation that knock control is working. I'm certain a little more timing will do wonders for enhancing boost onset.
That's the mechanical stuff, but there's a near endless list of body and interior details to attend to. All things in due time...for now, it is time to DRIVE IT.

Confirmed tonight with another 930 that boost onset is waaaaaay late, way too soft and just doesn't hold. You can hear the turbo working, but that pressurized air is going bye-bye. Going to have to spend some time with a lit cigar and an air compressor this weekend to find that leak.

I'll say that even with a boost leak and limited to .5 BAR... Damn this car is fast!

oh yes......boost issues aside...this is a beast......that motor sounds very healthy...in a decidedly nasty and serious way.

Check all bolts holding the intercooler down, and look close at the pipe between the turbo and the intercooler to ensure it's sufficiently engaged at both ends.

Sweet 930 you have.

Kenik I find it funny that you parked next to a civic hybrid in the picture. opposite ends of the spectrum for fuel consumption.

Wait until you get the car sorted and turn up the boost. It will be your rocket ship for sure.

^ Welcome to Microsoft. There seem to be three axes of cars here: Green drivers (the number of Teslas here is ridiculous), those who don't give a **** and buy whatever the latest TV commercial tells them to and car people. There's an annual Microsoft car show for charity and there are some REAL cars that show up like a Lola Can Am car, straight 8 Alfa, L88 Vettes, and other really neat stuff.

When this car is finally run .9 BAR without boost leaks, OMFG. Not sure my mind will stay in one piece.

Great shot. Love the scruffy look with mismatched Fuchs too.

Funny, the compulsion to make things perfect. I've think I've loved my cars most when they're scruffy and full of character. Character is harder to come by on perfect cars.

I know what you mean. But the car just looks honest. Imperfect and perfect at the same time.

An observation: Electromotive's WinTec4 tuning software is from another era, when "intuitive user interface" and "software" were from different planets. Needless to say, working through the arcane UI and less than useful user manual, I've had to fall back upon the knowledge of others.

Setting up the boost control solenoid in Wintec is comical - only because finding the setting is impossible...because the "Boost Control" isn't actually boost control as most of us would think about it. See this image? To set up a boost controller, you DON'T use the "Boost Control" option. That option is for speed threshold based boost control, designed for drag racers, if-and-only-if, you've configured a speed sensor.


To set max boost, you need to use "Full Table (PWM)", which allows you to configure full table control of the boost solenoid via pulse width modulation, which ultimately sets the dump setting on the wastegate. Sound confusing? It is, until it is explained to you.

First you need to know the frequency in Hz of the boost controller - in this case, the standard GM/Delphi unit is 30Hz (Thanks, Richard Clewett!)
Then you click "Table Select" and set a value of 1, which intuitively means your reference table is the MAP/RPM table.

From there, you must then double-click the words "Edit Table", because they look oh-so-clickable, right? Then, and only then, do you finally get the boost table, which is an overlay of the ignition table, which allows you to configure the boost control:


Now you can see MAP pressure in kPa, which if you divide by two, gives you BAR.
The 0 and 100 values are the duty cycle, which mean full open and full closed. Net-net, you put 100 in the cells with the value that represents your chosen boost threshold, which causes the wastegate to be actuated, dumping boost at your chosen point.

Intuitive, right?

Speaking of the ignition table, here's mine for reference:


Lots of tuning left to go. The knock sensors still don't work, so won't tune for power until I can detect knock. But in the meantime, I am pretty close to having smooth startup and idle figured out.
