Thread: MAF->MAP conversion with Tunercode?

any suggestions on sensor brands ?

Here's the one I'm using: bmotorsports.com GM IAT Sensor

Dave

thank you!

and this goes into the charge pipe?

I use a similar (identical?) IAT sensor as Dave from here: Sensors - DIYAutoTune.com
(They have bungs too if you need.)

Yes, it goes in the charge pipe. I like it as close to the TB as feasibly possible, but I know other intelligent minds who prefer to see it somewhere else that gets much less heat soak, like up front right after the intercooler.

Yes. Here's my installation:



I made a bung on my lathe and tapped it with a 3/8" NPT tap, and welded it on with an acetylene torch (not real pretty, but works fine). It's on the cold pipe, before the idle air pipe. (SR20DET in S13)

so for temporary would something like this work..

with this

then thread the sensor into that?

No, you need a 3/8" NPT port and that's only 1/2" NPT, unless you can find an open element sensor that's 1/2" NPT, then it would work fine. The bushing is 3/8 to 1/2, so won't thread into the 1/2 port.

ah i misread that

Looking forward getting a NEMU ECU myself! ITB´s mmm...

It will require another download, but this one will be publicly available for download as a DEMO and will update you to the full version when you plug in your NEMU.



This should certainly work well with an ITB setup, it is flexible enough that you can setup the load scales however you see fit.

For example you can use MAP load for idle and very light throttle and can switch to TPS load (alphaN) when over 20% throttle. This helps a GREAT deal with tuning an ITB car.
