I'm thinking about it, but willwait till I see dave next as we might just fit an alarm for overboost. Link to comment Share on other sites More sharing options...

That's not the best price. And that guy on ebay has got a very average feedback score of 96.9%. Mod your car has it for 189.05 Link to comment Share on other sites More sharing options...

An overboost alarm wouldn't be the best for me matty as I think it would be to late by the time I heard it!I think the turbo fuse is cheap insurance for me but will look around for the best price.

A more experienced tuner maybe able to clarify this but here goes.... from my experience with boost tuning the factory PCM has two overboost scalars, one that 'detects' overboost and one that will cause the PCM to enter "failure management effects mode (FMEM)"....commonly referred to as 'limp mode'. A good example of this is when you have a factory tune and you go and fit a big cat/dump pipe, you get it on boost and then the "wastegate boost failure management effects mode" is triggered. This system is only used when tuning boost in “closed loop” mode using the factory proportional-integral-derivative (PID) controller. You see the factory PCM has a duty cycle table that tells it how much to open the wastegate, from there it measures a level of error against another table called the ‘desired boost table’. The error factor is then referenced against another table called the ‘proportional gain multiplier’ table which it uses to determine how much the duty cycle table needs to be modified to achieve the desired level of boost!!So basically if the level of error exceeds that specified by the PCM’s ‘P1227’ level (Wastegate Failed Closed - Over Pressure) then the PCM will enter FMEM….and the engine is protected.But the problem is you really need to have a good mechanical boost control set-up in order to run closed loop, which is why a lot of tuners are forced to use the open loop method that sacrifices the over boost protection. It’s just unfortunate that the hose failed and I’m pretty sure this is how Simon (XFT) lunched one of his built engines in his BA F6 too. Just clamp it up good and proper and you shouldn’t have an issue. Link to comment Share on other sites More sharing options...

I prefer closed loop myself as it's easier to tune on the street since you have more data available via the pcm to measure what the boost control is doing. If you're using a dyno then open loop is generally the preferred method by most. But yeah closed loop is good when street tuning....which isn't really safe, particuarly for those that tune for a living and do a lot of cars!

I suppose the real question is, can the car be tuned with open loop mode with the use of the existing solenoid, or can you only use this mode (open) with a aftermarket boost controller?Sorry for the hijack matty Edited 17/02/10 07:48 AM by RUS531 Link to comment Share on other sites More sharing options...

Any feedback from anyone?The reason I asked is because the link took me to the product catalogue page instead of the turbo fuse page found under boost controllers. Also the link says "go fast bits" Link to comment Share on other sites More sharing options...

Also the link says "go fast bits"So it does, The link in my post that you click on says "go fast bits" but the actual webpage is- http://www.gofastbits.com.au/turbo-fuse. It seems the first time you click on this link it takes you to the screen that you mentioned then the next time it will take you to the proper link?Fugging cookies...Copy and paste the web page will be easier, otherwise click on boost controllers, Turbo FuseLink didn't work again because I had a full stop at the end which it included, FFS!
