  1. Thanks for posting this, my Cobalt SS unit came in today so I'll be playing with it over the next couple days. The sensor wires are external connectors as shown so easily accessible. There are only three wires on C2, pins 4 - 6 with 4 and 5 being purple.
  2. I did a heritage test today, and I'm Norwegian, Swedish, and Danish. I could have gotten 100% Scandinavian but I didn't Finnish in time.
  3. Market driven. And '70s cams were pretty lame on just about everything.
  4. 4 valve heads have more curtain area so respond to low lift better than two valve heads. 0.050" is a good parameter for judging SBC cams and such while 1 mm (0.040") is more commonly used with 4 valve cams. The 2.0 has 212 degrees at 0.040", the 2.5 only has 208. Also has four degrees more duration at over 0.300" lift according to this thread: https://forum.miata.net/vb/showthread.php?t=564488 Shifts the curve up in rpm but still need centrelines 'n stuff for a direct comparison...
  5. Another thought: I know there are external adjustments (pots) to rebalance the unit after work to get the left and right response even again, any way of tapping in there?
  6. Yes, the signal from the steering torque sensors mimics the torsion bar and spool valve action. Modifying that signal to a lower value should give lower assist, independent of outside CAN bus inputs. Two separate control layers from what I understand. And I suspected that altering the EPS software was not on the table other than a simple faking of a speed sensor signal on an early unit as you say. From wiki: "Hall-effect sensors are linear transducers. As a result, such sensors require a linear circuit for processing of the sensor output signal. Such a linear circuit: - p
  7. A hooded robber burst into a Kansas bank and forced the tellers to load a sack full of cash.On his way out the door, a brave Kansas customer grabbed the hood and pulled it off, revealing the robber's face.The robber shot the customer without a moment’s hesitation.He then looked around the bank and noticed one of the tellers looking straight at him. The robber instantly shot him also. Everyone in the bank, by now very scared, looked intently down at the floor in silence. The robber yelled, "Well, did anyone else see my face?" There are a few moments of utter silence in which everyon
  8. I guess I'll have a look inside once my Cobalt SS unit gets here to see how the torque sensor can be modified. Looks possible, thanks for the diagram.
  9. Maybe; the signal varies according to the amount of torque that the unit senses on the steering shaft. It may be as simple as adding a resistor/potentiometer to that circuit to reduce the signal voltage and decrease the amount of assist. The external control from the BCM etc. probably has a table of speed vs that signal to supply the factory programmed amount of assist.
  10. The EPS uses a 0-5v signal to determine the amount of power assist. I wonder if a person could tap into that signal; maybe that's what the DIY kit does either directly or indirectly. Edit to reply: unless I (and maybe you) can use the Cobalt unit and get the desired result without having to buy another EPS unit and DIY kit. Win-win for me if so!
  11. So probably uses a speed signal to set the amount of assist. I wonder if the DIY kit just needs a different connector for the Cobalt unit and may be wired in directly. Does yours have a separate plug to the PS ECU?
  12. I bought a 2007 Cobalt SS unit with the idea that it would provide more feel than an SUV unit, but it sounds like I might have jumped the gun. I see their kit doesn't work with that one. Somehow that figures! I'll have a good look at it when it arrives but I only saw that two main power leads.
