SG shows 24% when cold, rising to 37% when warm. Any ideas as to what's going on?

There are two possibilities.

1, The torque settings may be off on your PD.
2, your SG may be off.

I'm leaning towards #2. Do you have access to VCDS?
It's the only accurate way to see what's going on.

I didnt know they had these things for the VW diesels. I thought the toys were only available for the big diesel trucks?

Im going to have to rethink my choices in vehicles.

The .216 nozzles are said to be good for 10 -20 hp and 20 - 40 ft lb of torque by themselves

The SG may need a setting set , I don't know , I hear they are not so useful for diesels, so I did not buy one. I think idle load is more like 10% , just to get the Girl spinning.


Here is a diesel generator load chart and accompany fuel economy
You do not get something for nothing so you pay for load and rpm.
The way it reads is 50% load is the more efficient load.

I found a good Paper on economy and diesels
its not quite what I was looking for but its still interesting maybe useful & touches on engine load.

100% load is the most efficient according to that chart (1/2 load uses more than half the fuel of 100% load), that would mirror what I've found in my tank to tank fill ups. Not really that effective in real life as my tyres are showing signs of the abuse

SG doesn't really seem to give trustworthy info on any of my vehicles, petrol or diesel, there's always something that's out

Good observation , You must be one fast guy on the Road as 100% load is pretty quick off the line , remember that chart put 100% load as the thirstiest load and you do not need 100% load to accelerate.

100% load is top performance not top economy , ricer makes it work you make it work so it can be done, its not my style , its my anti style , neat it must take some finesse to pull it off, as it is the highest fuel consumption load.

So got all the parts in, but I don't have the time to install anything til next week. I tried the proracing tuning box, and it was nothing but trouble. Check engine light and other issues. Returned it already.

I have been using my vp37 fuel pump tuning box for a few years with success and no check engine lights. This week I turned it up a 1/4 turn with some smoking and somewhat increased acceleration. I have been pulsing the throttle in a attempt to clear the injectors and it seems to have worked. As now when I test floor it it makes double the smoke from the first few days of driving with it turned up. It seems to me the injectors are cleaner / flowing more fuel from me pulsing them while driving with the tuning box turned up.

When I bought mine the seller had all positive feed back with it and everyone agreed , it worked.
Sorry to hear it did not work with your car , very disappointing for you.
