Hondata

I’ve been working on a datalogger module and some custom gauges for my 05 S2000with a Kpro ECU.

I like the Hondata app on my phone but am frustrated I can’t read any of my analog sensors through the app, is there any way those could be added in to the wireless output messages?

Also, for my ...

Never mind on that second slope, I was an idiot and the tool I made was referencing the high fuel table even though it wasn’t in VTEC. Referencing the correct table I get the same slope.

Thank you for the info!

Is that a constant offset for all voltages or is that centered around 12V or 14V?

Seems like I should hook a scope up and measure the voltage across the injector pins (at the injector) and measure the voltage across them as well as the battery voltage.
I could then ...

Also, does the reported injector time in the datalog include the dead time or is it the time in addition to the dead time?

What should they be for ID1050Xs (50psi)?
I just followed the dead times provided by ID for the listed pressure.

Any ideas on this?
I’m kinda at a loss on what to adjust to solve this.
After looking at the log closely I noticed that the MAP value towards the beginning is actually slightly higher, but I know the next load cell up is correct because if I turn on the AC and headlights it falls squarely in that ...

I've noticed that on warm starts the car idles lean and has to trim a good bit positive then goes negative after a minute then finally stabilizes close to zero.

Attached is the calibration and datalogs
(Recorded a cold start and let it warm up, then turned the car off and reuploaded the calibration ...

Thanks for the info.

Any chance the analog inputs could ever be broadcasted over bluetooth in the future?

I'll try adding something like a 45Hz low pass filter to the input or restrictor in series with the sensor to see if it cleans it up.

I have a few questions about the analog inputs on the KproV4.

First question is about the sample rate of the analog inputs.
I have a 30-2130-150 150psi pressure sensor monitoring the oil pressure (teed off of the supercharger oil feed).
At idle it fluctuates around 2psi and when driving at a ...

Thanks!
That did it.
Wouldn’t have thought that was necessary.
I appreciate the help with this.

Assuming that the provided calibration was loaded on to the ECU any guesses to why the ECU is behaving this way?

Understood.
Would that 50mV offset count as custom though?

Pretty sure it was the same calibration, I literally saved the calibration and then hit upload before I started the datalog and didn't play with any of those check boxes.
I will try again tonight to be sure though.

Regardless any thoughts on why it is behaving like that?
The only thing I can think ...

Still working on getting things sorted out with the car.
05 S2000
PRB-A08 modified with AP2 connectors
Kpro V4
Wideband output wired to analog 0

AFR reported by the ECU matches the gauge.
The ECU seems to be trimming the fuel in the wrong direction.
When the engine first starts in open loop it stay ...
