Actuator Getting Stuck?

See if he'll give you the tune file as well, then you can go somewhere else from now on. You'll need the tune file as other tuners can't extract the tunes from the xCal (this is my understanding anyway) and would need to do a complete re-tune again.

I'm sure they can pull tune out and store it and start again. Tunehouse wins best workshop in Aus, and by the look's of it price's skyrocket.

Sounds like bollocks to me. I ran mine for ages with the standard actuator, injectors and fuel pump at about 270rwkw (I did have a cooler though) and it just couldn't hold the boost occasionally was the only down side. It came on boost real hard too and I was running 12.8's and leaving most V8's standing.

That's pretty much what I was after. I want it to come on boost hard and early, that's the whole fun of driving a turbo car. With the street tune that I'm running now, you start to hear the spool sound at about 3000 rpm but there's no surge of acceleration, (like it had with the stock tune) it just start to pickup speed gradually like a N/A car.

Riptide, what happens when it doesn't hold boost? Does it suddenly let go of power? What does it feel like and is that bad for the car?

[riptide]

I don't think it does any damage, it didn't do any to mine that I know of and I drove it pretty hard all the time. I had just recently bought it so I had too

I couldn't really feel it letting the boost let go but my tuner said it would peak and drop back and then just wouldn't make any more. Sometimes when I'd drop the pedal off and then go back on it wouldn't spool quite as well as it did with a full spool up, if you know what I mean? Even so it still went REAL WELL considering the lack off mods. At the drags it almost coasted from about half way due to the standard injectors running out of legs.

My mate reckons he can feel the flapper opening and closing a little when holding WOT.

There is somewhere in the tune that controls the speed the boost comes on. We tried setting it so it came on hard but ended up turning it back a bit so my wife didn't kill herself taking it up the shops.

Riptide do you run a boost guage in the the car?

[riptide]

I didn't then. Just going by the feel on the road and the readings on the dyno. I'm running an LM2 now off the OBD2 port but have a 12psi actuator also which seems to hold over 20psi. I wouldn't mind a boost gauge, you cant beat the old style dial.

[JVK]

With the amount of fiddling you do I am supprised you dont have one,cheap insurance.Was curious about your mates feel for boost fluctation as im having something similar but only about 1lb but

pulsing in and out,Bit annoying but doesnt appear tune/software related.Maybe my 12ib actuator has a small hole in the diaphragm.

[riptide]

That's how my mate explained it "pulsing in and out" in his BF with standard actuator running max boost.

I do have a pressure relief valve made from a 50m/m BOV but yeah, a boost gauge would be nice.

I wonder if it's to do with the tension setting on your actuator??

[JVK]

Yeah could be Ill have to look into that.

Thanks.
