Ok well I have a little bit more info:
I deleted my pukka paid for retail boxed version and installed one that I errr, "found" online. (I don't condone this but feel no guilt myself as I have the paid for version in my possession).
I'm now the same a Kikie, my GI-Max and speedo rev burner work fine, nothing from the tachometer rev burner though.
Weirdly if I install patch 1.02 and set simdash to patch 1.02 then nothing works ?!?
However if I tell simdash it's not patched the GI-max and speedo work again.
I'm not sure if it'll help but if I set the GI-max to blink when the RPM is under 1000 it always blinks (infact I set it to blink if the rpm is under 5 and it always blinks)
Not sure what other combos, options I can try but again if I can help please let me know :-)
