| The only real problem you have with using the Techlusion, or a PCIII for that matter, is that you can only add fuel, and under certain conditions/parameters.
Replacing the ECU gives you the option to adjust the ignition to, as well as adding/removing fuelling at pinpoint postions in the map.
That's not to say they don't/can't work well, but you'll need some dyno time and a good operator to get the best out of them. |
