any decent software tuner could do it. dunno if there are any simple DIY ways, maybe with tunerpro and a custom XDF, but defintely not with a GT1 or anything like that.
So if I will use this circuit hall to vs I will get the proper speed signal for dme and the abs will operate correctly without abs light on?
Yes. You can verify with the contact I sent you.
The ABS "sees" very high impedance with circuit connected, almost nothing is drained from the ABS so it works normally. The output signal will be a pseudo-VR signal.
What is everyone else with OBD2 doing for the VSS signal???
PM me. Ill take one just to see if it works and if i have an issue in the future. As i mentioned, ive never had a car code on me as its still receiving some sort of VSS signal although low come to find out.
No, I think without a VSS signal OBD2 won't let the motor rev beyond around 5400 rpm. Correct me if I'm wrong...
no, what I'm saying is with the wrong VSS signal (9 pulse instead of 48) at some speed it will cross the threshold where it doesn't enact the limiter. so you wouldn't notice it if you were going say, 70+mph, because even though the DME is seeing 1/5 of that speed it's just over the threshold.
what's interesting is the E46 appears to use a 10 pulse signal from the ABS computer but I haven't completely finished that project to verify. I'm fairly confident it doesn't use a 48 pulse signal though.
