Rob W Posted March 3, 2018 Report Share Posted March 3, 2018 Ign Trim Tables Could someone please tell me which cylinders should be paired There is an example in the help files for wasted spark but it's for a 6 cylinder, so I'm sort of not sure. Sorry couldn't find anything in the search Quote Link to comment Share on other sites More sharing options...

Stevieturbo Posted March 4, 2018 Report Share Posted March 4, 2018 If by WRX you mean a Subaru, firing order is 1324.. Pair 1+2 and 3+4 But what exactly are you pairing and why ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 5, 2018 Report Share Posted March 5, 2018 3 hours ago, Stevieturbo said: But what exactly are you pairing and why ? I suspect the OP's query "ign trim tables" was for the knock control ignition retard tables. With wasted spark ignition our ECU's cant retard individual cylinders, we can only retard the pair of cylinders that are attached to the same ignition drive. So you point these pairs of cylinders to the same ignition trim table. Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted March 6, 2018 Report Share Posted March 6, 2018 Surely as long as crank/cam are present it still knows which cylinder is active at any given time despite wasted spark so it should be able to trim on a per cylinder basis ? Or is it just a Link software thing ? Quote Link to comment Share on other sites More sharing options...
