2012 GU boost controller?

[Coldcomfort]

What EGT level hauling at 14psi? Maybe just working, for your set up but yes lower PSI = >EGTs
Do u experience limp?

Just read this.

EGT for just flat and level driving is about 200c. At 14 psi under load it gets to aroung 400c. Never in the red and to be expected. I always thought that a turbo would be allowed to spool up higher under load than on flat normal driving.

Whats limp? Is that limp mode?

These EGTs are low actually, so no problem there. I run 180hp /530 N-m FMIC / Procharge stage 3 / 4" induction and cruise 280-350 / haul hard goes 500-550C.

Keep under 600 for CRD (550 very safe).....

Need to spin up fast early/low down for spool up but need to keep boost under control _ management of vanes opening.

Occurs with stock ECM when you hold excessive MAF volts / MAP for longer time peridod say 10 sec. Set max boost say in 3rd gear (if manual) hauling up hill at say 3000rpm (under load) with needle closed _ adjust Dawes to obtain the max B without limp (limp mode_yes).

All the best with the journey a bit of hose is not your problem.

Should I consider a ECM remap after this? I'm in Adelaide but I also spend a bit of time in Melbourne... Is there a place that is good and trustworthy? How much is it on average? Cheers all.

Good remap would be very worthwhile. Best to to do it locally (Adelaide) incase follow up is needed.

Did mine 5yrs ago, first was a postal where you send your ECM to a tuner and they will perform remap in accordance with your drive requirements. A local live tune though is preferred and this is what I did subsequent to original postal (ECPT Tuggerah, NSW)..

Cost, guessing may be: postal $800-900 / live $1100 you need to ring and check.

Where:
Melbourne_I would check out Diesel Tec in Lilydale 03 97395031

Adelaide _ Not known over of there but suggest you ring Jon at JonnyTig Industries and ask for a recommendation. Three yrs ago I visited JT industries for works on a TM cooler and he spoke of a good tuner in Adelaide. Would not harm giving him a call for advice:

If you need, let me know an I can make contact.

Others maybe able to suggest a tuner.

That what confuses me. If I am driving up long hills, like the Adelaide hills, it boosts to about 14psi max. And EGT rises. Doesn't go into the red but definitely goes higher. Normal. When on flat road no extra load it hovers around 16-17 PSI. EGT drops way down.

This is because the solenoid is stopping the turbo from spooling faster than it needs too. Simply adding a needle valve in will do away with the solenoid and you will have full control.
In this situation where its hitting 14psi and EGTs are rising, if you had a needle valve installed, you would just shut off the needle valve a little more to restrict the air bleed, this will in turn rise the spool rate of the turbo.

ordered the controller. Looks simple to install. I'll post my thoughts about it here when it gets here.

I have one on my crd. Had dawes/needle on it then got car tuned and the spring wasn't holding boost above 18psi so tuner suggested one of these and installed it set to 21psi and I have had 0 issues with it since installed 2 years ago when tune got done!!!

boost controller turned up yesterday. Installed it today. Simple to do. But so far I cannot get more than 10psi boost no matter how much I adjust it. I'll keep tinkering but so far not so good.
