Default Anyone used the Dash Logic on the C7Z?

Curious if anyone has used one of these and had any luck with it?

http://www.palmerperformance.com/sto...products_id=92




I'd like to use it for monitoring ethanol %, KR etc etc...and controlling the NPP exhaust at the flip of a switch while driving would be cool.

Just curious....I did a search and not a lot of info or pics came up.

I have one but have been using my nGauge lately.
There is some info about NPP & C7 compatibility I posted in here: https://www.corvetteforum.com/forums...-2015-z51.html

Here is a copy of my config/setup that has the PIDs for KR (1001) and ALC%(27). Mine is just re-labeled E85 which I know makes no sense because it can read to 100%.

Awesome post! Thanks. Yeah Iíll definitely need the pids.

Just ordered the Dash Logic, should be here tomorrow and Iíll start fiddling with it.

You can see the full PID table in the software you use to program the unit. I think its under "custom alarms".

Good luck on your 2016 I have only seen this work 50% of the time on 16's and 100% of the time on 15's, not sure what the difference is.
Its 100% failure rate on 17's and above though.

Damn that sucks to hear! Hope it works. If not, I hope Amazon will return it... lol.

Seems like it works pretty well and easy to configure:






The NPP exhaust control function is cool too, but for some reason when using Closed mode with the Dash Logic, I get an intermitten "burble" that seems like the valves cracking open and closing real quick. The car doesn't do this in Stealth mode from the Infotainment screen so its definitely something with the Dash Logic control but....Not a huge deal.

Pretty cool little device and not having to add gauges or tear the dash apart to hide gadgets in the cubby hole is a plus.

Can you get it to read Intake Air Temperature 3 or Intake Manifold Temperature to see what the S/C output air temp is? The Z06 has 3 IAT sensors two of them are ahead of the S/C and the third one is at the output of the S/C along with the pressure sensor.

No, just IAT1 (intake) & IAT2 (post blower/intercooler). The only thing I know of to see MAT temp is HP Tuners.
EDIT: IAT3 is "Manifold Air Temp" I believe, which is calculated using a lot of things like both IATs, ambient temp, fluid temps etc. to come up with a "virtual temperature" which can control timing.

Right, I could not find MATS in the Dash Logic PID selection. I did put IAT2 on one page but I know its basically useless. There has got to be a way to find PID for MATs... If HPT can see it, the Dash Logic should be able too.

The LT4 has three IAT Sensors:
IAT 1 and 2 are part of the Multifunction Intake Air Sensor which also includes the Humidity, MAF and Barometric sensors. IAT2 doesn't tell you what the charge air temp is. It is part of Module B75C. DTCs related to these two sensors are: P0096 IAT2 Performance; P0097 IAT2 Low Voltage; P0098 IAT2 High Voltage; P0099 IAT2 Voltage Intermittent; P0111 IAT1 Performance; P0112 IAT1 Low Voltage; P0113 IAT1 High Voltage; P00114 IAT1 Intermittent.

IAT3 is integrated with the Intake Manifold Pressure and Air Temperature Sensor which is located at the back of the S/C housing so it can measure charge air pressure and temperature. It is part of Module B65. DTCs related to this sensor are: P00E9 IAT3 Performance; P00EA IAT3 Low Voltage; P00EB IAT3 High Voltage; P00EC IAT3 Intermittent.

If the instrument you are using is measuring IAT2 does it really read what GM calls IAT3 or does it just read what GM calls IAT2? If it measures what GM calls IAT2 you aren't seeing the charge air temperature.

There is no need to calculate IAT3 since it is an actual sensor and its data is used by the ECM.

There has to be clear communication between the instrument designers and the people using them about what temperature they are actually displaying. So far I haven't seen any such indication of that kind of clear communication. You can't SWAG that what some other engine/charger manufacturer did will apply to the LT4.

I talked to HP Tuners and they said their $500 tool would read IAT3 but $500 is a lot to pay for data that is available in the system that any tool could read if the programming was set up to read it.

This would be a great tool just to see e content and AITs, is it true these wont work on 2017s and newer?

Ok, I was assuming IAT2 was on the back of the S/C housing because the temperatures are always much higher than IAT1.
Im not sure what physical sensor its reading as IAT2. I have an nGauge and the Dashlogic and whatever IAT2 is it reads the same temperatures on both.

So if IAT 1&2 are both in the intake side why is there normally a 30-50 degree difference in temperature between them at any given time?
IAT1 seems to always be close to what the ambient temp sensor is reading.

If I sit idling on a hot day I will see IAT2 begin to rise, where IAT1 will remain close to ambient.
Once I begin to drive/move forward again IAT2 drops rapidly.
Is this because the air is moving over the heat exchange now or the MAF, or both?

Good posts guys! Keep them coming.


in HPT, we can see MATs... so there has to be a pid for it that DL and NGauge can read.

Not calculated BS but a real post blower temp sensor.

I'm hoping that HP tuners is close to releasing the MPVI2 Pro Feature Set with standalone logging that works with our cars.
Then we can log all of the channels we want, it still would be nice able to see this stuff in a real time gauge without having to drive around with a laptop though.

Yes, it only works on 15's and *some 16's.

I assume since both sensors are included in the same module with the MAF one reads air temp into MAF and the other reads air temp out of the MAF.

Bill, I don't know if that makes sense because that would be the same temperature, as stated above, IAT2 can be quite a bit higher than IAT1, but when moving (cruising) and out of boost, it shouldn't be much different with no heat being generated by the blower (comparatively).

The ECM references MAT for IAT spark modification so IATx is really just for observation anyways.
