CardiffSupra Posted March 10, 2007 Share Posted March 10, 2007 I think the cut kicks in at 1.0, But if you have a fcd you shouldnt have a problem with fuel cut. Quote Link to comment Share on other sites More sharing options...
imi Posted March 10, 2007 Share Posted March 10, 2007 Good to hear its back and running properly Must be a relief after all this time! The dyno figures are odd though, for the boost the rw figure is way too low, the flywheel one more or less is right. Seeing as the dyno registers rw power it means something ain't right! Probably the dyno operator not knowing how to do an auto (and the tip's are an absolute nightmare apparently). Quote Link to comment Share on other sites More sharing options...
vvteye Posted March 11, 2007 Author Share Posted March 11, 2007 I think the cut kicks in at 1.0, But if you have a fcd you shouldnt have a problem with fuel cut. Yeah, however I have a hks fcd which allows you to dial a setting. the HKS FCD modifies the boost sensor's voltage seen by the ECU. Depending on the setting used, the severity of voltage modification (and fuel cut pressure) can be varied. For example, the setting, 7, results in 4.08 volts seen by the ECU when the boost sensor is outputting 5 volts. Setting #5 results in 3.69 volts to the ECU with 5 volts sensor output, and recommended setting #9 for the supra results in 4.44 volts to the ECU with 5 volts sensor output. so with that in mind I noted in the early days it was set on 8 and I moved it to 9. Today I moved it back to 8 and will tyake it out later to see the effect. Any of you experts out there have any advice on why this is not a good idea?

downimpact Posted March 11, 2007 Share Posted March 11, 2007 Finally finished... for a little while then When we went to tatsu the acceleration from 70 compared to mine was very impressive Can't wait to see it the next meet (april 2nd) Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted March 11, 2007 Share Posted March 11, 2007 Glad you have your car up and running again, you should speak to Darren about Dyno figures for your BPU VVTI. He has accurate ones, you dont Quote Link to comment Share on other sites More sharing options...
Clarkey Posted March 11, 2007 Share Posted March 11, 2007 I did a run at Surrey rolling road (1.15 bar BPU) and that came out at 338.7 BHP rear wheels and their estimate was 405.3 BHP on the Flywheel. Ro I took my old T61 supe to SRR. Charlie is a good lad, let me play his PS2 while I was waiting. At only 1.1 bar of boost mine made simliar figures to yours Ro. At the flywheel: 456bhp @ 6200 RPM 442 ft lbs of torque @ 4300 RPM At the rears 383bhp 375 ft lbs Quote Link to comment Share on other sites More sharing options...
