Thu, 17 November 2005 00:45 Hi, After building and tuning my own ECU I have experienced this kind of thing several times. It was usually due to lean mix on opening the throttle, like the carby guy said. Whether due to a bad ground, (or initial guess tuning in my case)or whatever. Check your TPS. Usually they have a switch to tell the ECU the throttle is closed (i.e. 'idle mode' or not) and a potentiometer used to detected rate of throttle movement for enrichment/enleanement. If these aren't working the ECU's fuelling stratgies wont function the way you expect. (i.e. properly) Cheers, Nick. [Report message to a moderator]
