Have you tried this guy here with refurbishing your ECU?After replacing my leaking ECU capacitors, I'm not convinced my ECU is 100% fixed. Extremely frustrating! If there was an economically Plug-n-Play, aftermarket ECU with OEM+ functionality (boost/timing control, engine monitoring, traction control, auto transmission management, etc.), without spending thousands+++ on bespoke tuning and sensors, I'd be all over it.
OEMs do not individually dyno tune each mass-produced vehicle... it would be nice to have a modern plug-n-play aftermarket ECU option that replicates the stock engine parameters without additional dyno tuning.
