MAP sensor wiring help PLEASE!

[COVID-19]

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.

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.

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.

^ 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.

You should check yours and share the info 😀

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?

[Cubieman]

My refresh rate is set at 10Hz (default).

[duracellttu]

My refresh rate is set at 10Hz (default).

I'll go back and check again with 10Hz setting, but it didnt make a difference when I was toggling between realtime and 50Hz.

Its the physical location of the sensor making those patterns you are seeing. I did those 2 tests about 10 minutes apart and you could see a direct result when the sensor was moved from the throttle body (Kassel) location to the brake servo line location. But again nobody has said if there is anything inherently "bad" with the Kassel location, tons of people use it, they just aren't busting out the laptops with testo and viewing the data like we are.
I could not tell one but of difference driving the car with the sensor moved to a different location but thats NOT to say that it isn't affecting the DME in some way when it oscillates like that. That is something I do NOT know and would be curious to find out.

So you bought the remaining stock of them? Lol.

And for anyone having issues with Testo prompting for COM port 9, just change the COM port requirement in the .ini file to use COM port 1 so you don't need to go into device manager each time you use a different app. That's what I did.

I ordered them a while back they been stuck there for almost 2 weeks. I just found someone local to 3D print them with a slight modification so it can fit a bit more flush.

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

Terra, just for the record, which MAP sensor are you using? Is this the same model as what comes with the Kassel adapter?

Cubie, when you did the back to back data collection between the Kassel adapter and the inline brake booster adapter, did you use the exact same MAP sensor? or did you have a second one? If you had a second, were the two you had the same exact model?

Just want to rule out any potential variables here...

Nice man!

I used the MAP sensor included with the Kassel "kit" in both tests as well as Kassel's wiring. So as far as the pre-made kits go I had it easy, the brake servo adapter put the sensor it the correct spot and the Kassel wiring made wiring stupid easy after I got over the fear factor of course. But I could have easily created the wiring, the parts are out there.
