Interesting. Are you willing to post your experience on having a custom programmed ECU? <P>I was wondering if the one your are selling could have been my old one. I swapped Terence my stock ECU for his IPD ECU. When he had his custom ECU done, he also had an extra one sitting around.<P>I know if you disconnect the battery, the ECU will eventually lose it's memory and go back to the default settings. My question is, is the memory for the ECU contained in the ECU? If so, I might be interested in your ECU. I find it difficult finding a block of time where I can disconnect my battery so the settings will reset. But then again, I might be interested in upgrading to a custom chip after you share your experience.
