I wouldn't be disappointed. A Dynodynamics in shootout mode is about as reliable as it gets. However, forget the flywheel hp. You have 192hp at the wheels. This is the REAL figure that the machine measured. The operator then puts in a multiplication factor to arrive at the flywheel figure in order to keep pub talk happy. It's a shame the other graph isn't in wheel hp as well. Then you could reliably compare results. By my basic estimations, your 192hp ATW gives 250+hp at the flywheel. |

A bigger intercooler will always be better for sure - but the low-boost conversion was developed with the Forge intercooler, and plenty of cars have made 250-260 BHP with it, so I don't think it the main reason this car is under-performing.  ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

So by keeping the same intercooler and uprating everything else like you would on high boost, you can still hit over 260bhp hint hint? ________________________________________ Team allesclar ® |

It went on the rollers again [at skip browns this time] and they said that the mapping was untidy at part throttle and could be tidied up. The bigger ring made the fuelling lean out but didn't really add a noticeable power gain so it went back off. ________________________________________ Ex SC-6Now in a Megane R26 |

craig... get the compression test done.. get diagnostics run on all sensors.. then concentrate on timing and then look at the map. As these maps accomodate alot of variations hence why there is no real need for a custom map!when did you go skip browns? printout? ________________________________________ Team Supercharged Gti-6NV Motorsport Automotive Performance Tuning 0121 448 7515 ECU Remapping/ DPF removal VAG/BMW Diag and Option Coding Peugeot Planet ECU coding/transponder programming etc www.nvmotorsport.com Facebook Page Project S6 |

in fairness too craig, your car was idling around 800 rpm, thats seems a tad bit low  ________________________________________ Team allesclar ® |

I really can't see it losing compression since the last test, it was compression tested before it had a top end rebuild. As for sensors, the Lambda, CTS and ICV are all new genuine replacements. I will look at the Map sensor and the TPS though. Also it ran and idled perfectly before the boost so the sensors should still be fine. It was more of a diagnostics than a power run, I was seeing if it was worth fitting the restricter with a 4% bigger hole in it. The operator was holding it at varying revs and monitoring the AFR, this is why he mentioned the map issues at low throttle openings. As said above the mixture become a little lean with the larger ring in it and I reverted back to the smaller one to reduce damage. On the run there was no smoke and it hasn't used any oil in the 1500 miles it's done so far. I think the next thing will be a trip to chipwizards for a look at the timing. If that shows nothing up then a compression test will be looked at. ________________________________________ Ex SC-6Now in a Megane R26 |

What was the point in that? partial throttle afrs arent any use to diagnose your issue. In all honesty this sc setup will not be perfect as say a pos boost setup usimg a standalone ecu.A timing check wont take long.. although id use a scope and a dial gauge Let me know when you book with wayne as i need a power run  ________________________________________ Team Supercharged Gti-6NV Motorsport Automotive Performance Tuning 0121 448 7515 ECU Remapping/ DPF removal VAG/BMW Diag and Option Coding Peugeot Planet ECU coding/transponder programming etc www.nvmotorsport.com Facebook Page Project S6 |

The map issues at low throttle openings are more likely to be lambda related than ECU software related.The ECU runs in closed loop at throttle angles less than 70% so will be constantly trimming the fuelling. You should have just taken it to Cchipwizards in the first place - taking it to someone that knows nothing about the conversion isn't going to help a lot. ________________________________________ Contact Details:rich@lynxpowerengineering.co.uk 07732 822546 |

It will be going to chipwizards when I have the money. This was as an exercise to make sure that the new boost ring wouldn't make it run lean [which it did].________________________________________ Ex SC-6Now in a Megane R26 |
