Updated CAN Protocol for AIM MXS (with all analogs and Lambda)
Posted: Tue Oct 08, 2019 10:04 am
Hi,
since i got lot of PM/emails asking for my custom AIM MXS CAN protocol for the KPRO V4, here is my version and documentation :
The Kpro can protocol included in the AIM library has some limitations :
- only 2 analog inputs returned, for specific sensors (not documented)
- no lambda value returned
So i developed a custom to read that.
First, you have to set-up the kpro board for the protocol to be used : Motec SDL/ADL
Then, you have to set-up the AIM Race studio software, download and install the protocol attached to this message.
Then, when you create a new configuration for a MXS, you choose the new protocol, and you have the following channels available :
All the analog channels are returned as raw millivolts values : you need to create a Math channel for each sensor to make it human readable,
for example, for a 0-10bar oil/fuel pressure sensor like this one : https://www.reveltronics.com/en/shop/60 ... -5v-detail
I had to set the following values :
I will not help you to create those math channels or to wire your sensors that requires pull-up resistors, you need to make your own calculations for this.
I you installed a kpro, a AIM dash, then you should be able to do a little maths !
If you do all this steps properly, you should be able to display some very interesting data : i have Lambda, EGT, Oil T°, Oil Pressure, fuel pressure, ... on my dash (when i want to confirm that everything is working as it should on track)
Thanks.
