So....I just installed Testo on the laptop and collected some data from the MAP pressure and MAP voltage. Data was collected on "Realtime" refresh rate.

Here is what I got. Initial dip in the curve is from startup.



Here is the data revving up to 3k twice.



Here is idle again and engine shutdown.



Data is consistent with what Cubieman collected. What impact do we really think this has on the engine while running?

terra / Cubieman - what refresh rates did you both collect data on?

^ after playing with it for a little bit. I had to make sure on the files from Testo that the .ini file said [serial] port=COM9 And make sure my usb was set to com9 under control panel-device manager. Tried it again and it didn’t work then swap to another USB port and it worked.

[Cubieman]

Forgive me if I'm dense but how to do I get to the MAP sensor screen on the current version of Testo?
Looks like things have changed a bit since the instructions posted on Ecuworx.

I followed the most current instructions on the Ecuworx page. But once you open it open make sure you check the box of whatever values you want displayed. In this case it would be MAP pressure/MAP pressure voltage

EDIT: also I found that I had to change the USB cable to COM9 through device manager or testo would not work.

Hmm, seems like something that could be 3d printable. Doesn't really need to be metal. Something that's resistant to oils and whatnot like nylon would probably work well.

I’m trying to find someone to do it but no luck.

Where are you guys getting those nice little adapters? I'm only finding them through UK vendors.

There's also these larger sizes. I don't have a booster hose handy but I'm guessing the 12mm *should* work.

12mm but most packages are stuck in the UK. (Even from Ebay vendors) Last order I got was from an eBay vendor with expedited shipping and the price was a bit too expensive.

I've had the kassel setup for about 2yrs but after seeing this thread, I'm planning to relocate mine to the brake booster area but am looking for the cleanest way to do this. I like Lang's option the best, but would probably need an additional adapter to connect to the oem map sensor. By doing what Cubieman did above, using the Kassel adapter and joining it to the vacuum tube would be the simplest, has anyone tested the effects of mounting locations? I read somewhere that the sensor needs to be mounted with the nipple pointed downwards for pressures to remain accurate.

CubieMan:

That picture is of a different style adapter than the Kassel and was only in that location for testing purposes as the previous owner had already cut the brake servo line there.
I later installed the MAP right by the brake servo, that is the cleanest installation as the cabin air filter covers it almost entirely.

COVID-19 Has the adapter style you are looking for.

My pictures are of the OE CSL sensor with the OE CSL rail FWIW

Good to know!

I am wrapping up a vacuum line refresh this weekend. After I get everything buttoned back up I plan to check mine. I'll report back with the findings.

Great findings! What software are you using to read the MAP data?

The last test case is to collect data from the OE / FSTT MAPS sensor location built into the air rail.

Do we have any reason to believe the air pressure is that turbulent and the readings are accurate?

Test results:

Test 1:

Moving wire so it wasn't close to injectors keeping MAP sensor mounted on Kassel adapter.
Testo:


Test 2:

Moving MAP to a different location, I mounted it here because the previous owner had already cut into the Brake Servo hose.


Testo:


I think that says it all!

Now this forms another question in my mind, is there any problems created by running the MAP in the "Kassel Location" with those oscillations?
