Welcome, finally more non-ECM, Carb & a Dizzy guys. I got a Twin AFR setup up on my Vintage Dirt late model here in upsate NY. 4150xp 4bbl & 500xp 2bbl. 355 w/MSD dist. would be interested to here some of youre results. Dave MK2 w/Rpi Dash & ShiftX3 (F&R brake pressure/fuel level/fue...

I also use a 6AL. nothing more to do wiring wise. but you'll need to configure the channel for the number of cyl's. I also seem to get spikes in my data. nothing seems to eliminate it completely. lmk if you also get spikes. Dave

both these sensors are available as presets in the app. just click the preset button within the channel your setting up, choose the correct sensor and it'll fill the values in for you.

more info here in the wiki. https://wiki.autosportlabs.com/RaceCapt ... ure_Sensor

I believe the AX's are terminated by default, which is why I put one on both ends. the AFR's are not, so are you saying this schematic is correct? thanks for replying.

Seasons over so im looking to clean up/simplify my wiring. I am looking to switch every sensor over to a canbus style harness. 8 linear sensors and two canbus AFR controllers. by using two AX's (one each end) and the AFR's/MK2 in the middle. would this work properly as far as canbus termination. see...

of the two you listed I would choose the Waveshare. mostly because it has the lugs in the four corners which would make install easier. both appear to have lugs for mounting the Pi. I used an older Waveshare which does not, so my Pi just hangs of the header. mine is a Waveshare 1024x600 resistive to...

Brent, did I read somewhere in one of your posts your looking at being able to import the Rpi gpios into racecapture as sensor inputs? i'm looking at using HR-SC04 ultrasonic sensors to measure static ride heights (used during shop chassis set-up). if so, how difficult would it be to add a dash page...

open the .kivy/config.ini file in your pi and replace the Input stuff so it looks likes this:

[input]
mouse = mouse
mtdev_%(name)s = probesysfs,provider=mtdev
hid_%(name)s = probesysfs,provider=hidinput
%(name)s = probesysfs,provider=hidinput

should get you working correctly.

Most all the MSD box's like a 6AL produce a 12volt square wave signal with a 20% duty cycle for a tach signal. simple answer is, yes.

its my gopro footage. at first i thought maybe it was a video issue. it just seems odd that i see the same rpm readings repeating. it will do the same thing sitting in the shop and reving the engine, as tho the display cant update fast enuff.

here's a link to a step by step a did for another racer. it may help. also has some tricks for faster boot speed.

Ok, so for future reference the logs are located in /home/pi/.kivy/logs. (I think, going by memory lol). you'll see a bunch of kivy_xx_x-x.txt because it logs a new one each time you open RCapp. personally, i'd like to see it overwrite, hint for brent. I think your next fix is in the /.kivy/config.i...

i'll try to help, but not an expert. I don't have the 7" official screen, but have run into a similar problem. try this first. if you can get to a pi command line (with internet access connected) type: sudo apt-get install xsel (that should install the xsel library) then type: sudo apt-get inst...

This will read the % of front vs rear. avgId = addChannel("FwdBrkBias", 10, 0, 0, 100, "%") function doBias() local a1 = getAnalog(0) local a2 = getAnalog(6) setChannel(avgId, ((a1 / (a1 + a2)) * 100)) end setTickRate(10) function onTick() doBias() end in this example: getAnalog(...

I'm not a lua expert but i'll try to help. If your pulling two analog channels then try this from the Lua Scripting examples. you'll end up with a virtual guage that will show front bias as a percent of front plus rear. should get you started in the right direction. prior to all this technology I've...
