Jeremy Towers Posted July 6, 2011 Report Posted July 6, 2011 Hi guys. I have just completed tuning the fuel maps on my L76 Holden V8 engine. Logs from my wideband sensor show maximum +-0.5 AFR errors. I have some issues with throttle response. Using the default accel settings, the response to small throttle changes is good if not a little touchy. However under heavy throttle gearchanges, the engine initially responds but then bogs  before coming right. It feels like the enrichment is ending too soon. My wideband AFR (for what it's worth) logs seem to confirm this more or less. The engine uses an electronic throttle which is working fine. Looking at the settings, should I be increasing the values in the 'clamp table'? Do the settings in this table also alter the response to small throttle changes ?, or is that solely set by the 'accel sens'? Your advice would be great. Thanks Jeremy Towers  Quote
Dtech Motorsport Posted July 11, 2011 Report Posted July 11, 2011 Hi Jeremy can you send me or post up the PCL file of your current tune as this will make it easier to see what is going on Regards Dave [email protected] www.dtechmotorsport.com Quote
Jeremy Towers Posted July 18, 2011 Author Report Posted July 18, 2011 Thanks for the offer of help Dave. I actually had some sucess increasing the Clamp table, but sadly now I have damaged my differential, so further tuning is on hold for a while. Regards, Jeremy Quote
