swamp Posted April 12, 2003 Share Posted April 12, 2003 ive fitted the additional loom (for data inputs 1-3) to 1=MAF, 2=air intake temp, 3=coolent temp, but the data reading being displayed or way out anybody know the correct settings i.e. LOW(V), and FIT, HIGH(V) and FIT ????

Alex Posted April 12, 2003 Share Posted April 12, 2003 The low voltage and high are the min and max variables which the system knows it will get a reading between. Take the throttle position sensor. Say its max is 10v and min is 0v if you set the fit to 100 (which will equal percent) at 9v the system will report 90% throttle. Well that's the principle anyway. Basically its a case of trial and error. It's not particularly intuitive and I found thatit get ballsed up by readings that get higher the lower the voltage that passes. This is true of the intake temp sensor. I started a thread about setting one up on my car (a j-spec) a while ago. Have a look for my name and a key word of "harness". it may help... It really is a case of knowing what you're looking for then tuning the Data inputs to reflect it. To find the min and max voltages could take some work with a multimeter and a willing passenger whilst you travel around. Well I assume you won't get a max value for the MAF unless the car is traveling..... Quote Link to comment Share on other sites More sharing options...
swamp Posted April 12, 2003 Author Share Posted April 12, 2003 cheers for that, sounds stright foward. ive got a list of the resistances for each sensor (min-max)..............time to get the calculator out. i just thought that someone may have done it already.
