Ah ok, as in a s15 ecu? I had already considered that for use on a p12 20v car, as they factory ecu is aparently not tunable, unless someone works out reflash. It would clearly need a cable throttle body to make it work, but not a huge job. I just need to talk one of my mates with p12 20v's to try it.
Im not entirely familiar with the s13 sr20det, is that multi coil too? as it see its listed for tunercode.
