Electrical bus protocols what I've found so far

I know man, me too - but that is yet another grand! :yikes: I was toying with the idea of the Evo fuel pressure mod, as I do believe that the Spyder suffers from a chronic lean condition even at bone stock. I especially liked the fact that it is adjustable and with the gage that you get with it it seems like you can dial it in pretty well. I just might buy another pressure regulator and do the mod knowing that I have one in my back pocket if I ever want to back it out. I just don't think I want to start chasing after a JB or a PC. More electronics on the machine is not sitting well with me at this point.

A few things to note---

The fuel pressure mod does NOT come with the gauge-- that is an extra $$$. You can probably buy a similar gauge at Harbor Freight--- but I did buy the Evo one...

In order to use the fuel pressure mod you cannot run the stock airbox-- gotta run the evo or maybe the kewlmetal

Good call on buying an extra regulator.

Ordered an AFR kit-- will install soon.....

This post along with the tutorials I have read is kind of bringing things together. How are you able to distinguish which sensor is which? Is it via the message identifiers or does the application do that for you?

I think the real challenge is going to be figuring out how to directly address the computer on the Spyder so that you can adjust the control laws within the program. I assume this is the ultimate goal here...

I used the data sheets from the racing version of the abs controller and the yaw rate sensor. Then I jacked up the Spyder and spun wheels individually turned steering etc

I can't modify VSS but I would like to record telemetry and gps tag it. And be able to cal sensors bleed brakes etc

Makes perfect sense. It's going to be very interesting to see where this goes. It's just cool to gain a better understanding of how things work.

Thank you

Someone emailed and asked so I thought I'd post it here.

That was me. Thank you Alton. I can see that I can get most of what I want this way. If my Spyder ever comes back from the shop, and if I then decide to keep her, I will take advantage of this to do my own servicing. :2thumbs:

I'll put up a cable diagram and where you can get a cheap analyzer later

That would be useful. I gather that you use the CAN bus monitor for performance logging and the OBD monitor to look at service items, though there is some overlap.

Thanks again for bringing us up to date. Keep up the good work.:bowdown:

Cheers;

Pogo.
