TTz Report post Posted April 17, 2007 Lambo___AF_chart.pdfHi Guys, Dyno Dynamics , 4wd dyno. Ramp rate 75% Temp ... 26c Model Murcie Oct 2003 It is not a kit car.... Lambo Aust have checked it out Something looks wrong, why would the power band just level out ? Could it be the fly by wire throttle bodies not fully opening? ie if it only opens 80% power could stay the same ? Is it an Emissions setting ie; like the e46 m3 ? The Air/fuel rations are all over the place except where the power band levels out ???Lambo___AF_chart.pdf Allan, I could not see your dyno sheet but from what everyone has said on your post it looks like you have something similar ? Taking it in to get the modules read to look for error codes etc. Still need help... rgds, TTz Quote Share this post Link to post Share on other sites More sharing options...

Id like to compare with mine to show them there is a problem. rgds, Yes, that is right in line with what you should be making. We then Dynoed Alex's car with full exhaust and it made 466awhp.

TTz Report post Posted April 26, 2007 wow, maybe it's in valet mode... Ash, Good power at 5400rpm... strange it just flat lined past that.. Just need to find whats happening with the ecu. Havent had much luck as yet.... Where going to do another few runs and hook the lambo computer up to it... This way we will see (maybe) whats shuting down ?

lambornima Report post Posted April 27, 2007 You better get that calculator checked Nima. edit, 32%. seriously though, the Murcielago isnt getting any more power to the ground than an F430? with 700 lbs less the F430 should stomp the a Murcielago. something isnt right about the 433 figure.

lambornima Report post Posted April 27, 2007 oops BTW, if the F430 is making 430 rwhp, that means 11% drivetrain loss (with calculator checked)? no way. Quote Share this post Link to post Share on other sites More sharing options...
TTz Report post Posted April 27, 2007 No other symptoms that I could tell, just sounded a little flat and failed to give that top end pull. One thought is it may have been fuel, Ie; service station putting low RON fuel and selling it as high RON fuel, ECU then backing everything off if it sensed pinging etc. and the higher the rev's it just back ingnition and fuel off. I'm going to book the Dyno next week and have a play.... Quote Share this post Link to post Share on other sites More sharing options...
