Hi all, I have a 1994 MX5 supercharged with a 'MiataLink', which as I understand it is based on the G1 Link ECU. These use a custom air temp sensor which modulates a signal based on temperature (Pulse Width Modulated, PWM). My sensor has appeared to have failed and thought I'd ask here on the slim chance that a) Link has any in stock b. someone has one sitting in their shed? Cheers
Hi Guys Time for another question on my ECU install, the alternator in the 99+ MX5's have charging controlled by the ECU. Now I struggled to find information here about this for the MX5's, but did find some info on Haltech's forums on how they control the alternator charging. The base settings are listed below so people can follow this discussion without opening a base map:Frequency: 250HzStart Duty: 75%Minimum Duty 0%Max Duty 100%Gain 100Target Voltage 14.7Output Inverted Please use a spare PWM output to the charge wire of the Alternator.Use a 470ohm pull up to 12v on the chosen PWM output.Please use the software settings previously mentioned.Remember to check to voltage at each RPM site before racing! I'm pretty sure this is not a problem to setup in Link, my question is more on the how I'll go about doing this, and what he means by "inverted output" and "470ohm pull up from 12v" Thanks in advance
