I think it would be a very worthwhile mod, if only done for the coilpacksMicra Ed said:Put bluntly the RNN14 is the only ecu that will work without a fair bit of playing about. The S14 ecu would work if you add coil packs and make wiring changes (Which would be a great thing to do since you can do more on that ECU) but its quite a lot of work, and would need a remap to suit the pulsar.
