Q&A Forum
Knock would be VERY handy. Sorry for the question what is " mic" you have referred to a few times?
What knock sensors are/would you use ?
Holden/GM do you have covered ?
Mic as in microphone jack on your computer or usb sound card.
Something like this.

Ideally im still looking for best option. One with. Mic in / Line in / Sound Out.
So then You can run knock and rpm off it at same time. And hook some headphone into it to manually listen to knock as well.
Its basically a 0-2.5v input with a good frequency range.
A knock sensor is just a microphone anyway. So its all in the filtering to get a usable signal out of it.
RPM is a little bit harder since youll need to use cirucit to drop voltage to safe level.
That circuit you linked in the other thread would work with 1 extra bit added to drop another 0.8v off that but Id also suspect the mic port would handle 3.3v fine.

Its sort of looking like It should be a seperate plugin tho just because the sound driver library in C# is quite large.
Datalogging will be for Holden and GM that uses memcals to tune and ALDU1 cable for datalogging.
So early to late 90s for Holden.
Late 80s to late 90s for GM.
I use EFILive for stuff thats 2000+ for tuning, OBD2 datalogging works other wise. (Looking into connecting there controller into dyno but thats lower on the list of stuff to do.)

Update #A3: (Almost stable enough for first submission to plugin library)
Gauges confirmed working.
Hides flash tab on non-supported adapters.
Flash commands confirmed working on OBD2B Honda (All I have on me to test today).
Cleaned up the GUI further.
Started support for 3 most common Honda OBD1 and Honda OBD0 datalogging.
Laid base logic for OBD1 Nissan and Holden/GM datalogging cables.
Looking into direct memory datalogging (24-28-32 eeprom using Ostrich 2.0).
Looking into adding mic input as another logged gauges (RPM and/or Knock).
Looks like you need a chassis/axke_hub dyno ! If we get busted in Australia doing power runs on the street we are clasified as " Hoons" and 2nd infringement the car is confiscated and crushed.
Ive got a rolling road with eddy brake and bench dyno with water brake. Road dyno is just a feature of my Hondyno Flash/Scan program since most people that are using dont have a dyno anywhere local. Its all good getting the fuel and timing dialed in but with out having a before and after do you really know the difference lol.
Yeah its same over here but not as bad.
4okph over speedlimit and loss of licence, And if the cop deems it as a boy racer act (Hoon but only really targeting males 30 and under) you get 1 strike on your name and a big fine along with the speeding ticket.
Get done 3 times car gets crushed.
Parents farm has nice big long private road around the outside of it.
Just have to make sure its clean first.
Came in real handy when I was growing up.

First video is demo just using a software obd2 simulator to feed values over serial port back into its self.
Have left it logging a run for a hour with just randomly generated changes and doesnt seem to be any memory leaks of anything.
CPU usage didnt go over 1.2% and ram didnt go over 50mb. (Do note the 1.2% cpu usage is on my PC 10 core /20 thread 5ghz.) So a little dell celeron that might be a lot of cpu usage.
2nd video is on my 2000 Euro R which is OBD2B. And 2 full throttle pulls down a private road using known weight of car and acceleration rate and work power out from that.
Might have another Update out later tonight since iv managed to punch in a bit more code for Honda OBD1 and OBD0 datalogging.
OBD1 Nissan and Holden/GM datalogging still working on punching that in at the moment.
Hi BMGJet , is this demo on your Honda EH9 civic ? I'm not familiar with Honda's what month and year Honda are we talking about here ?
Nice work on the Plugin.
Update #A2:
Lots more bug fixes and error catches.
Code for guages added (not yet confirmed working in real usage)
Reports function,
Added tooltips to buttons,
Added reset values button "R" to live data tab.
Base code for flashing OBD2A and OBD2B Honda ecus added (not yet confirmed working in real usage)
Code clean up and compression on lookup table (Still 502kb plugin but down from 890kb.)
GUI layout improvements (* Only been viewed on my 4K and 1440P screens so far so may look trash on low res screen still)Any for any one intrested, Im up to 4835 lines of code so far lol.
Have the bluebox with me for tonight to carry on coding.
Gauges look to be working.
Demo video.

And if any one was wondering how I banged out this plugin fast well, Its because its just stripped down version of my flash tuning software lol.
Looks a bit familiar lol.

Hi BMGJet, what about the Australian & New Zealand FORD ( falcons BA,BF & FG's) OBD2 connections will it work ?
My tuning support for Ford's only extends to au series 2. Should work with them tho for reading PIDs and error codes with the right scantool. Have tested with eBay elm that has switch on side of it for scanning Ford's.
Don't know of any flash commands tho since they are tuned using the jport.
Hi BMGJet , that is why I mentioned the Tactrix Openport 2.0 " ? Obd2 connector before , I know that works with the later model falcons. Not many people playing around with the Falcon AU series 1,2,&3's . More people are playing around with the Barra 4.0lt DOHC eninges in the Falcon BA,BF and FG's and not to mention the quad cam V8's. 😀

Just ignore this post. Im just testing what the forum supports for embeding images.

bmgjet, I would be interested to see how you identify the genuine OBD2 adapters. I bought 3 different adapters when I made the support for OBD2 RPM, but one of them I just could not get to work (version 2.1, which I read is crap). It does work with another scan tool I have though, so somehow I just did not get it right yet. BTW, I will send you a box for free, just need the shipping cost covered, let's talk off line.
Hi Jostein , Postage has been paid check your paypal account, sorry for the delay.

Very nice! Will be super when we can select PIDs to live view into gauges and graphs, looking forward!! I will add functionality to use plugin data for engine RPM for use with gear ratio calculation.
Your extra bluebox is being picked up tomorrow by FedEx.
