MAP sensor wiring help PLEASE!

[Cubieman]

Guys, does someone have Testo version with MSS54 Serial to check map sensor? I've downloaded last version and it seems that there is no Vanos bookmark with map parameters

So when you click "MAP preasure" over on the left it's doesn't graph or what? It looks like it's producing some kind of reading in your pic.
"MAP mbar = 1006"
"MAP V = 4.1"

Looks like your seeing MAP readings no?

Can you elaborate on how the Kassel MAP sensor would play with this harness modification? So if you have a Kassel MAP + Turner IAT... what wires go where from start to finish? I feel like I have an idea, but for the purposes of making this known here on the forum may be helpful to know to document for others.

Essentially just bypassed the adapter to the MAF harness and wired the IAT directly to the DME pins. Honestly if I had known when I got my airbox, I would have just made my own IAT harness for less and ended up with the same result but less headaches to get to this same point. It's literally two pins and you don't have to modify the factory harness at all. Aka easier to revert back to stock if ever needed.

Can someone confirm the Bosch 0 261 230 101 Map sensor works with CSL software? I think it's the one Kassel uses and they say it's CSL scaling on their site but when I look up that part number it's listed for a bunch of GM vehicles. I want to make sure I order the correct one.

TIA

That’s the correct one.

This is what I did. IAT was done with the turner harness and I removed the extra pins so the only two being used are from the IAT sensor and those convert into the maf connector using only the respective dme pins. Basically a direct connection to the dme but without having to hack the maf harness for easy reversion.

FYI the wires should be black and red only. I had to hack a spare terminal because one of them broke upon removal if you're trying replicate this based on color.

Also removed:



Done: (Should be red and black only. FYI: I broke the black terminal and had to crimp on the yellow connector if anyone needs this for reference)

Great. Thanks guys! Looks like a CSL airbox will be coming my way soon

[heinzboehmer]

Yup what he said ^

[Cubieman]

Thanks! So there’s basically no wire splicing required if you go AlphaN using this relocation kit? Or am I missing smth?

That's correct.

[Nick_P]

No MAP means you only need the IAT, so the alpha-n IAT relocation kit is what you want.

Here is a link to the wire w/pre-crimped terminal that go to the DME:

They are not the same as the type that go to the IAT/MAP. You can build your own harness with OE parts or find some on amazon/eBay etc. I wish I still had all the part #'s down somewhere.

Here are a few amazon items:
3 pin connection

2 pin connection

Read this thread for a better source of the part #'s required to build your own harness.

Where are people getting the single pin crimp terminals to make their own harness? Are the ones that go into the DME plug the same as the ones that go into the plugs for the MAP and IAT plugs? Is there an Amazon source or do they need to be OE?

A bit of a noob question here. I am slowly collecting all the parts needed for a carbon airbox install. I am planning on going with AlphaN since I don’t wanna deal with all the hassle when going for emissions, which means no MAP sensor.
My question is for a cleaner setup with less wire cutting/ splicing that is easier reversible back to stock, is it better to go with the Turner AlphaN IAT relocation kit

https://www.ecstuning.com/b-turner-motorsport-parts/turner-alpha-n-iat-sensor-relocation-kit-s54-s85/014579tmskt/

or with the Turner IAT relocation harnerss?
