I am new to the forum so forgive me in advance if there is an existing thread. I searched, but could not find. Has anyone developed an 8 individual cylinder EGT solution. My thought to minimize channel usage is to split left and right to one 0-5v channel each and sample each bank in a switched capacity such that every fourth record will be cylinder X. I could then decompose the two data sets using code to build the 8 EGT view. Just an initial thought.

Another approach might be to use an analog-to-CAN conversion module. For example this comes up in a Google search: http://www.texense.com/en/produits/raci ... n_104.html. Don't know for sure, but it might be pricey.

Thanks Brawta: I will investigate. When I get my RCP ( soon) I will be able to protype multiple configurations and concepts. Based on my research here are the parts of the puzzle so far:
1. Employ an 8:1 MUX chip (analog deviced ADG526A) and feed it to a programmable port to decompose the signal and write results to a 8 channel file.
2. Started reading the section on virtual ports that may/may not work with number 1.
3. I scratched out a hardware only solution that works, just need to come up to speed on CAN bus protocol.

My vehicle is a 1934 Ford roadster with a naturally aspirated engine. The engine is a V8 305cid that spins upward of 10,000 rpm. EGT, is my number one problem. Inlet pressure second, and the rest nice to know.

Keep us updated! if you want some help with the hardware design and contribute it as an open source project we can certainly help move that along. CAN bus integration is a really good idea.

Brent: I will keep you posted and of course I am all about open source. Just need to get it from brain to paper and then to prototype. Should have something emulated by end of January.

rocket6706, maybe you have already seen this: http://www.diyautotune.com/catalog/cane ... p-542.html

Brawta: It is an intriguing device for sure. I did come across it doing some research.
