I was futzing with my ScanGauge II and I set one of the gauges to display the air intake temperature. With an ambient air temp of around 45 degrees I pull in around 95 degree air on my completely stock airbox when I'm driving through town. If anyone has a CAI, wants to know how effective it is, and is willing to let me ride with you while the ScanGauge is connected let me know! I can come up with a testing process that would work across vendors and using my stock car as a baseline and the end result would be a nice real-world comparison.

I'm in the Vancouver area in Washington and would be willing to travel throughout the Portland metro. I'm waiting for a spare cable to show up and should be ready to perform testing by the middle of next week (around 4/8) - anyone game?

 

I have a scanguage II also - I have not spent too much time looking at the intake air temp - I will bring that up on the guage on Sat. I am running a Comptech intake so it would be interesting to see what temp differnt intakes are getting.

One thing is you need to compare them on the same day with the same temp.

 

Sounds like a good idea depending on what time of day I would be interested. I have an AEM V2.

 

There is also the matter of checking the calibration of the air intake sensor - if the sensor readings are off in the car it would completely throw the collected data. I think the best way to approach this short of inserting another known calibrated sensor or swapping the intake components around on one known good vehicle would be to take an initial reading when the entire engine is at ambient air temp. Then the air can be measured with a known good source and the test cars compared to that.

I think as well that as long the ambient temp and humidity is with in I'll say 10 degrees/percent that the testing can run on the theory of relative differences between a baseline setup. It might not be perfect but it's a manageable testing process. Perfect testing would involve everyone going through tests to be at the same physical location at the same time all with their cars already at ambient air temps - I'm not sure how practical such a requirement would be but perhaps this would work if done at the same time as a group meet?


Awesome! They are neat little gizmos aren't they? Have you had any luck in getting your ScanGauge II to run in FAST rate mode? I had RPM, engine load, water temp, and ignition timing gauges displayed at NORMAL rate but some of the gauges would be flakey at the FAST rate. I'm now running reliably on FAST with the following gauges: RPM, water temp, intake temp, and MAP. It seems only certain components work reliably in FAST.

The horsepower gauge is flakey at all data rates, I can't figure out what's going on with that one.

 

I have an K&N setup. I'm in Camas. I'm will be around this weekend.

 

My second cable for the ScanGauge came in and I'm ready to start some testing however I'm tied up for the rest of the weekend. I'll be ready to start on Monday April 6, 2009 however.

Remember that the testing has to start with an engine that's at ambient air temp to validate the intake thermometer - with out that as a starting basis we can't put faith in the data collected.

 

Very interesting, subscribed!

 

it would be interesting to see the result on some of the high end set up such as asm and j's.
