honda civic integra ppr with 2.4

posted Apr 11, 2016 17:58:24 by Christopher Zemla
hey guys, i'm having trouble setting the ppr for my 95 civic. I have it all hooked up, and it's giving me the wrong values for the rpm any ideas. just to make sure ppr needs to be set at 02:00 right?

Hi Christopher,

I've heard a few people are having an issue with the RPM calculation. I'm investigating right now and will post an immediate code update with a fix when I determine what the problem is. You are correct, your PPR should be 2.00 -- the 0.1 is only meant in extreme circumstances when a precise calculation is needed. 99% of the time a whole number is used. Stay tuned -- I'll get back soon with a solution.

Can you tell me what's happening at certain RPM points -- what is the car at vs what is the shift-light reading?

Hi Christopher -

Have you tried using the SENS mode FREQ instead? Let me know

It's reading close to correct around 700-1000 after that it x2 so around 2000 it's reading 4000. I tried send mode and got nothing but 9999 out if it.

Hi Christopher,

I just uploaded a new code v2.41

Run the EEPROM Reset code first, then upload this new code. Let me know how it goes.

so i got around to messing with the car, ive been trying to upload the code and i keep getting this message

Arduino: 1.6.8 (Mac OS X), Board: "Arduino Nano, ATmega328"

/Users/christopherzemla/Downloads/ShiftLightV2_41-master/ShiftLightV2_41/ShiftLightV2_41.ino:36:111: fatal error: TM1637Display.h: No such file or directory
#include <TM1637Display.h> //#include <Adafruit_LEDBackpack.h>
compilation terminated.
exit status 1
Error compiling for board Arduino Nano.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

any idea how to get around this?

Hi Christopher,

Looks like you're missing the TM1637 library (i'm not sure why it's asking for the Adafruit_LEDBackpack library too) - it can be found in the zip file here;

Instructions for installing libraries can be found here:

If it still gives you errors for the Adafruit_LEDBackpack, that can be found in this library folder

Hope this helps
Let me know what happens

well i got it to update, ive never messed with arduinos before this so it was something new.
it's still got the same problem i've made a video and uploaded it to youtube.
and the ppr is set to 2.00

Hi Christopher,

I will do additional research. As of now, the only suggestion I have is to ensure you have the correct RPM signal wire and make sure you have a good power and ground to the Shift Light. Try changing your power source or ground location and see if it improves.

Other ideas that come to mind are to try a PPR of 4 or 1 and see how that affects the code. Try turning on/off the "cond" feature or try switching the SENS method again to Freq or Intr.

Let me know how it goes. Sorry this isn't working quite right yet, but I'll do my best to get it up and running for ya.
