Are you losing coolant? Are you spraying coolant anywhere on full boost (esp. out of the overflow tank)?
I don't think ECU logging will help diagnose this one Shav....as much as we love logging, there are some things that laptops just can't pickup!
Helped a guy in Brisbane diagnose that his heads had not kifted / no HG failure etc via logging. Then confirmed by his mechanic with a TK test. Ended up being a split Throttle hose. Everyone was telling him HG.
Some things can be diagnosed
Other thing is that this car is an auto, so it could be a cracked trans cooler pipe in the radiator or even the oil cooler on the oil filter has a crack
I have some questions -
How did a split Throttle body hose cause HG symptoms (spraying coolant everywhere, coolant running out, oil in coolant, overheating issues or if severe - white smoke and rough idle etc)?
If you diagnosed it 100% through logging, why do a TK test to confirm?
Aside from those things.....for constructiveness' sake, how would you go about logging for a HG failure? My HG showed no symptoms in logs. I guess you could use coolant temps to help diagnose, but by the time they reach boiling point even the stock needle will be skyrocketing.
As convenient as logging is - in cases like this the mechanical side of things becomes more important and logging only takes on a secondary role to maybe check if you're on the right track. It is so much easier to test for a HG mechanically than it is to log it. If it was a crack in the radiator - I imagine his radiator pressure tests would have come up looking sour.
Could be the oil cooler....could be the turbo....if we can eliminate the block as being the culprit, that saves the OP some $$...although it sounds like he's already thinking evil thoughts about a built E85 running monster block
