  5. Holy cow! Diagnosing a faulty turbocharger is not very hard if you know what you are doing. Sounds like the mechanic caused the problem and does not know how to fix it. I know tuners/workshops in Sydney who see problems with Barra's all the time - they charge a fixed amount to diagnose, and then come up with fixed cost solutions before proceeding. $5k for this is ridiculous! Yet you seem to think this is allright... like those hostages who develop attachment to their captors...

  6. I agree with both of you, I was just stating the fact you cannot overlook the importance of street tuning, it has it's place as does dyno tuning.

  7. That is the other thing, a roller dyno is so far from a proper load cell dyno. You really need a proper load cell to hit all possible cells and hold the car in a cell long enough to get steady state data. The repeatability of a roller dyno is trash as well, tyre temps, pressures and just plain position of the wheel on the roller all affect it too much. Obviously better than street tuning, but if you are going to find the time to hire a dyno, at least hire a modern load cell one. The oem calibrators I've spoken to said it takes almost a second within each load point for the engine to reach true steady state, they said you can see it in the data that if it isn't held there long enough the data you get is wrong. Where street tuning (or logging really) shines is creating a scatter plot of rpm vs load. You can then see if all you have properly scaled the breakpoints of the tables to match where you spend the majority of time. If the scatter plot is all bunched up in one corner you can quickly see where you should be rescaling and changing the break points. We added a "reinterpolate all referenced tables" function in the pcmtec editor exactly for this function, it auto re calculates all the cells to match the new axis, and when an axis is shared with multiple tables it does the whole lot for you.

  10. Car needs to go to an expert for correct diagnoses. Your mechanic is obviously lacking if its taken this long...

  11. 120 for limp mode in the zf, about 129-130 for the engine oil. 110 degrees at eastern creek with my big derale cooler and fan and limp mode came from engine temps not trans. Wakefield zf sits at about 100-105. This is in winter so single digit ambient temps. Awesome write up, might tackle a zf service at some stage.
