nissan200sx.dk Posted November 10, 2012 Report Share Posted November 10, 2012 Hi. Would this be possible to act as slip control? Quote Link to comment Share on other sites More sharing options...
Scott Posted November 11, 2012 Report Share Posted November 11, 2012 Good morning, Yes, this would provide a form of slip control. The exact numbers you need would take some experimenting :twisted: Quite often traction control systems will integrate a few different methods including throttle plate control, engine limiting and retarding the ignition timing. Cheers, Scott. Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted November 12, 2012 Author Report Share Posted November 12, 2012 Thanks. I can only set the numbers 100rpms up or down at a time.. could.this be changed in firmware?. Also can i somehow combine this with 4d ignition retard / slip..? Quote Link to comment Share on other sites More sharing options...
Scott Posted November 12, 2012 Report Share Posted November 12, 2012 Hi, The 100 rpm precision for the limiting table could not be changed easily. Yes, you could setup a 4D ignition table, with % slip on one axis and RPM (or load, or nothing) on the other axis. Then you could either have the 4D Ignition table on all the time or have it activate only under certain conditions using a virtual auxiliary.

nissan200sx.dk Posted November 12, 2012 Author Report Share Posted November 12, 2012 I already have the 4d with slip % and rpm table, but could that be combined with this GP rpm limit table? Quote Link to comment Share on other sites More sharing options...
Scott Posted November 12, 2012 Report Share Posted November 12, 2012 Good morning, Currently there is no way to layer limit tables, but I'm not sure I understand what you are trying to achieve. As one table is limiting (cutting) ignition or fuel, and the other is retarding ignition I do not see how you would integrate them. Using the two separate tables with slip % on the axis will mean they work in conjunction. Cheers, Scott Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted November 12, 2012 Author Report Share Posted November 12, 2012 4d ignition either work on dry or wet road... using both could maybe make it work on both surfaces. It was just an idea. :-) Ronni Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted November 12, 2012 Author Report Share Posted November 12, 2012 Would it be possible to hook up a dial to adjust more or less 4d retard? depending on how dry / wet it is. Quote Link to comment Share on other sites More sharing options...
gts_215i Posted November 13, 2012 Report Share Posted November 13, 2012 What are the axises on the 4d ignition table ? Reading the thread, my first thought would of been gear or gear/speed ratio - to provide separate slip % and control for each gear ! For a adjustment control - install a variable resistor or voltage and setup in the inputs ! (May have to use GP) Then use this input as the axis vs slip% in the 4d table. All sounds good in theory, but haven't checked to see what variables are available in the table axis selection Quote Link to comment Share on other sites More sharing options...
Scott Posted November 13, 2012 Report Share Posted November 13, 2012 Hi Guys, All good suggestions. You could set up a 4D ignition table with RPM and % slip on the axis. Then you could set up a 5D ignition table with Gear and a spare AN Volt channel on the axis. You could connect a potentiometer to the AN Volt channel and set the channel to "Voltage 0-5V" Tuning it might be a bit of a pain as there are so many parameters, but hopefully you would end up something you are quite happy with at the end of it.
