In order for it to be calibrated it would need a standard to be calibrated to. In this case the standard is what Bosch decided it to be. According to the data sheet (http://www.finjector.com/verkkokaupp...0280130085.pdf) the resistance value should be within a +-5.4% deviation from the nominal curve.

I'm a little disappointed the data sheet only has one data point and a relatively vague plot but in the grand scheme even getting that information is loads more than you can expect from Denso or Magnetti Marelli.

Link(Ecu) says there's only 1 degree difference in the operating range between these two sensors.

Here's the info of the 039

The time constant and nominal resistance are drastically different though, so not sure that it matters.

At any rate, NTC sensors obey a specific curve defined by a specific formula. The typical approach is to just manually obtain enough datapoints to solve for the constants in the formula you can have as many datapoints along the curve as you want, by just plugging values in the formula.

The true "calibration" data for such a sensor would be these 3 constants, as this is equivalent to not just giving the curve, but the mathematical formula for the curve. They are unique to every single sensor though.

Yeah, this whole curve business is a little annoying to me. I've been thinking about removing the thermistor and installing an RTD element instead.

Forgot the snap rings for the turbo at the shop. Can't assemble it until this weekend. Blah.

Capped off the old PCV port on the manifold.


Shifter is bolted up. It niiiiice.


The modified compressor housing looks like it'll work.


Picked up a Walbro 255 from Poik earlier. Finally got that in the mail. I also got a couple of really nice 0-7bar pressure transducers from my buddy Daniel. I'll be using one for oil and one for fuel.

This is coming along nicely. I'm really loving that shifter as well.

I'm mostly interested to see the power output and powerband with those 16v pistons - I have a set to toss into my FT block for the 16v swap but was hesitant to stuff them in.

Yeah, I'm also looking forward to seeing how this combo works out.

Bolted up the VEMS panel. The factory kick panel cover fits perfectly over top of it. I was going to crimp and connectorize the bulkhead connector, but I forgot the pins and crimper at work. Doh.



Turbo is re-assembled and installed.



Spent way too long ****ing with that stupid piece of **** snap ring on the compressor housing. After much swearing, breaking one of the tangs off the snap ring, more swearing, and a ****ty "custom tool", I got it in place.





I also spent a bunch of time going through the green manuals to get some of the less than stellar wiring sorted out. Some of the wires around the washer pump have flaking insulation and need to be replaced. I also need to do some connector splicing since I've bolted on different headlights and turn signals.

At this point I'm slogging through all the little **** jobs that need to be done but aren't visible.

Now that... is a piece of work. I love it.

That is a super sweet custom tool. Those snap rings can be a giant pain to get in and out. If your special tool fails, get a pair of these:



Knipex 44 21 J21. I use these whenever I'm working with a compressor snap ring. They work.

They look like they're too small. The HX35 snap-ring is about 200mm in diameter.

200mm!

I have a really nice pair I bought awhile ago that look like those pictured above, worked well for my GT35R, but it is only about 100mm I would say.

Glad to know I'm not the only one that is ready to kill a bitch while messing with one of those snap rings.

I have been brought into fits of rage by turbo snap rings. I think I pounded a broken carb I had lying around into little pieces with a sledge after trying to take a comp cover off.

I use these on hx snap rings. I think they were 50 bux. They do internal/external rings.



Thanks for inspiring the volvo community.

Well shoot, I guess I've never tried those pliers on giant novelty-size Holset snap rings. I know that they do work for all the Garrett snap ring compressor housings. Anything bigger than a GT35R gets a bolted connection.

I always struggle with the dam compressor ring on the dam hx40. it's scary as hell when that thing slips off the channel locks with a ton of force. sometimes i'll get the snap ring on the compressor housing easy, sometimes it'll take me literally an hour to get it on by myself. It really easy if you have two people, one person with snap rings, the other person with a flat head guiding the ring into its slot.

I use the same thing as Karl basically. Two pieces of 1"x0.375" flatbar, each, about 40" long, with a pivot in the middle, and small bolts through the end ground to fit the snap ring.

When the bolts get mangled I replace 'em. Best tool.

What you capped off is the idle port. looking awesome, the na 16v pistons will work fine.

Thanks for clarifying. I kinda don't care what the port was for.

I'm not wild about the lack of E85 out here, but pump gas should get me enough power to have plenty of fun.
