12200411 - A Few General Questions

[ezobens]

JTR offers a drive shaft mounted VSS http://www.jagsthatrun.com/Pages/Par...ctor-Diff.html

Pics below show a custom built VSS assembly, similar to the JTR part.

Nice hardware but seems a bit more complicated than I need to just get a speed signal?
I see that Dakota Digital makes a model SEN-01-2 VSS that fits Ford (and my SS700) that is an 8K pulse generator-
Can the 12200411 be modified to accept this 8K signal? If so, I'm golden and it's only like $35!

Below is screen shot of the EFI Live '0411 speedometer calibrations. ETC is Electronic Throttle Control. 8K pulses seems like a calibration challenge.

Since I have never played with these PCMs before, I still have a lot to learn.
I know that GM had 2K and 4K pulse VSS but what does that equate to in the table you provided above?
Is that 2K or 4K per revolution or per KM or?
Again, I apologize for the dumb question(s) but I do want to learn about all this stuff.
Thank you for your patience!

40 pulses per drive shaft revolution for PCM's .... 2K / 4K for ECM's

EFILive has very good speedometer parameters available. Pulse generators (2K/ 4K / 8K / 16K) are generally no problem to configure - you just need to think outside of the box a little.

When you are actually ready - post your tune, tire size, gear ratio, and pulse generator type (i.e. 4K) and I will set it up for you.

Outstanding!
I'll be taking you up on that.
Thanks so much!

May be some help, also offer 2/K adapter.

This particular VSS won't work wit my Keisler SS700 because it uses a Ford style VSS housing (o-ring fitting vs threaded ).
Thanks for looking!

Ah, right forgot about your SS700 speedo drive.
