My driveshaft speed sensor did not have to be spliced into the dash, it pulls the VSS and driveshaft speed from the xfi

Correct at a frame rate of whatever the xfi spits out, I would say 20 fps.

Your going to need to split the signal and wire it direct. I havn't played with it enough but if you also wire the tach in the other input the DASH can calculate what gear your in. All the standard engine sensors are shared via CAN.

Kinda confilicting info. I guess I'll wait until the car is up and running and see what is going on there. Kidglock, with it shared, can you output mph on your dash?
Another questions. Is anyone using the dash as a boost controler? I'm thinking about using it to do boost based on mph.
You can display the XFI DS data but your limited to the logging rate of the CAN. It depends on the functionality and accuracy your looking for. The Dash has a much faster logging rate over the CAN signal from the XFI.Kinda confilicting info. I guess I'll wait until the car is up and running and see what is going on there.

If you want it to calculate the gear then you will have to splice into the line, if your just displaying mph and driveshaft speed it will pull that info from the xfi.
For the boost based on mph you can use the xfi egr table as well.

The pwm from the dash is a good idea, as it gives you a 16 x 16 grid instead of 8x8 and you can base it off tps/mph or any of the logged parameters on the XFI can bus or even the dash sensors. However , this is open loop boost control.
I'm not planning to use the dash for logging anyways. So your agreeing that as long as I only want to see mph on the dash that I don't need to splice it in.
What is the downside to open loop control? Is it inconsistent?
I'm using CO2 regulated to 80 psi if it matters.
It may creep 1-2 psi at top end, depending on gate size. However if you know this you can take some duty cycle out on the top end slighty to compensate, if you use the mph table. The XFI 2.0 has no mph table for boost it is only time in PA mode or TPS based, unless you use the dash or egr table.
As far as the Co2 goes I thought the rule was not use more than 10 psi above the boost you plan to run? The c02 maybe constant but your engine bp is not that is why it will creep.

You are good to go then.I'm not planning to use the dash for logging anyways. So your agreeing that as long as I only want to see mph on the dash that I don't need to splice it in.
Please post a pic with Key on car not running............and set scale to psi
