We call it IAT in the JB4 logs, it's the charge air temperature. Temperature of air entering the engine post intercooler.

Hi Terry,

A feature request, I'll put $50 PayPal to you on it, and I'm sure others would be willing to pitch it.

Real time knock sensor readout.

In all my Subarus, our Cobb accessport timer had gauges similar to the JB4 app. It offered FEEDBACK KNOCK and FINE KNOCK LEARNING so you could see in real time how the engine it's taking to your fuel quality. Very nice instead of having to pull and view a datalog to look at ign1 values.

Is there anything similar that can be read and displayed for the Q50?

Sometimes I can hear and feel the knock if hot out and loading in low rpms... The engine must be advertising this info.

Thank you!


2018 Q50 RS400 AWD (w/Sport Mufflers)

Loving the ride...

Yes this is great request. This would tell a lot about what brands of fuels are harmful.

The ECU is so fast it pulls timing on a per cylinder basis before you can even hear knock, and if it pulls enough timing fast enough it throws a code. Additional logging for stock turbo applications is useless but at some point people will start bolting on much larger turbos and for when that time comes we do plan to improve the logging channels.

We did this because some people were worried about heat soak which we already proved as a myth with our n54 DCI.

Goal is to do the same testing with OEM intake and compare.
Tried the same test in 65 degree weather at night. My IAT continued to rise to about 140 degrees after idling for 20 minutes. Not exactly sure why that is the case.

Honestly though, it may have something to do with my install. I'm not sure if it was due to my intake being from the initial production batch, but the install was a bit rough. Required some bending of the heat shields on both sides to clear certain engine components. And required quite a bit of manipulating of the factory inlet hoses to get the brackets and intakes to seat right. It's still not perfect, but they work as is and the current fitment is the best I could get out of my kit.

It might be that your car is logging MAF temperature rather than charge air temperature. I've seen it on a couple cars. There are maybe 6 temperature channels that spit out in an array and the JB4 picks out the right one to display. The only channel we care about is charge air temperature (air temp entering engine after turbo and intercooler) and that won't change much from moment to moment. If your temperature is rising quickly when stopped and dropping quickly when moving it's the wrong parameter.

Hi terry. This is what we’re seeing, or at least a few people that I know who have jb4. The IAT in our jb4 interface changes sharply moment to moment depending on how fast the car is moving. Can you please have this looked at and verified. Thank you.

Interesting, I guess the better question is who has it working properly? It's fine in our test cars and other local cars I've checked. Perhaps a model year or ECU software variance we'll need to accomidate for.

If anyone local has the issue would be helpful to swing by our office so we can pull some more advanced CANbus data off the car and fix the bug!

Alternatively if anyone has a BMS data cable and knows how to use a serial emulator like RealTerm we could sort it remotely.

I'm in South Carolina and my IAT will rise at a stop light and then cool off after i start moving a bit. Once I slow down it starts to rise again.

Terry are you saying this isn't normal?

MAF intake temperature is normal, but charge air temperature should remain relatively stable.

Terry,
I'll be buying a JB4 for my SS in a bit. I work with uc's a bunch and use RealTerm SuperPutty etc extensively. Will let you know once installed

Thanks. Was able to get some data and will play around next week to see if I can get to the bottom of it.

Only reason I’m asking is because I see the .hex files on the first page.. I try to download them and they can’t be read.. so idk what I’m doing wrong lol
