Thanks, I'll give it a shot in awhile, though I am pretty sure I tried that combo.

What does RDSC stand for? Did a quick search but it didn't reveal anything.

From the FAQ

Q. What is "Tip in bump spark"?
A. Tip in bump spark is for low speed drivability in a manual, between tip in bump spark and RDSC (RPM derivative spark control) it adjusts the spark to smooth throttle transitions so you you can cruise the carpark in comfort.

Argh, thanks, I looked through the EFI acronyms/abbreviations (got them bookmarked) didn't find it so I went to google...
I remember reading that now you mention it!

Cheers

Still no joy. Screen shot taken while driving around 40-45km/h ish.

doesn't A6F Bin use C xdf? Prob the same flags though

Good spot, I must have loaded the wrong XDF when I was playing around before I had the hardware setup. I'll try it again with the correct XDF just incase it makes a difference, though the flags are the same.

that xdf doesn't seem right, VS V8 Series 3 all ran getrags? So the hi res flag should be on for both manual and auto tunes, it isn't, so looking at 3807 and 3808 the only bits that stay on with auto/man is 3807 bit 4 and 7 and 3808 bit 2 so turning one of those off should change vss. I think Hi Res should have been 3807 bit 7 not 3808

Anyway give the test 1,2,3 a go in the xdf ive attached, i think test 2 will do it.

That did the trick.
I had:
Man Trans 1 = Set
Man Trans 2 = Set
HiRes VSS = Set

Test 1,2 and 3 = Set (VSS Worked)

Test 2 and 3 = Set (VSS Worked)

Test 3 = Set (VSS Worked)

Test 1,2 and 3 = NOT set (VSS Worked)

Not sure if that will help you narrow it down, but at least it's working now. Let me know if there are any specific combinations you want me to try.

from a stock manual bin file all those 6 flags are set. From what your saying that works, yet from your previous posts it didn't.

To me a stock bin file shouldn't work as your using a T5 sensor not a getrag/auto sensor, so you only should need to UNSET one of those flags to switch VSS modes.

So not sure what's going on there with your testing.

Yeah, that's what I was thinking, it didn't make any sense why is started working when I tried again with your updated XDF but the HiRess VSS flagged
