Scottie-GNZ Posted February 10, 2008 Share Posted February 10, 2008 Need a little help here guys. Engine wants to idle at 10.9:1 - 11..3:1, rich, I know, but when I crack the throttle, it instantly goes extreme lean. The engine is very sensitive to the Minimum Inj On Time seting but I feel like there are other parameters that can help correct. have never built a TPS Blend table and the Accel Enrichments settings are somewhat baffling. Those seem to be ones that might (should) have an effect on off-idle and low-speed acceleration. I am not running an IAC and this issue seems to have started recently yet cannot think of anything I have done that would have cause that. Any thoughts? Its almost as if when I crack the throtlle I suddenly have a massive vacuum leak, LOL, but has not effect on WOT performance. Quote Link to comment Share on other sites More sharing options...

Is AFR steady or hunting? Quote Link to comment Share on other sites More sharing options...
jgkurz Posted February 10, 2008 Share Posted February 10, 2008 This may seem obvious but have you checked the TPS to make sure the closed and WOT voltages are still correct? Maybe the min and max settings on the Tec2 got changed inadvertently. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted February 11, 2008 Author Share Posted February 11, 2008 AFR is not rock-steady at idle, but it does not hunt. Rich at idle and the instant you crack the throtlle, it goes full lean, beyond the display range of the AEM WB gauge. TPS is set using "Autocal". It initially sets them correctly but then the HIGH always seems to reset itself to "000". I recall mentioning this once and was told the TEC2 does not reference the HIGH. Strangely enough, the low failure value is 0.04 and I never get a failure signal. Maybe Tim will chime in. Quote Link to comment Share on other sites More sharing options...
