30FE Overboost

ArktisE92 · 08-15-2009, 11:39 PM

Guys, after many trials and tribulations I finally got my Procede to work in the very hot asian weather here (where 230-250F oil temps are common after a 15 minute drive). The ignition timing is great to play with, but with anything more aggressive than stock Stage 1 (say, 80% ignition advance) I keep triggering the 30FE Overboost code at 3-4k rpm.

Thing is, the boost logged at the point of limp doesn't seem outrageous--typically between 160-170kpa as reported by BT, which translates to less than 10-11 psi.

I suspect some of you are going to say Doomsday maps or better cooling--but before I resort to lesser maps or hardware rigs, is there a more elegant workaround so the ECU doesn't assert itself as aggressively in cutting power?

p.s. FWIW I'm running 29.2 on MSD80...

Anyone from Vishnu cares to chime in? I'll do a couple runs tonight and post the results here... hopefully somebody knowledgeable will be able to help...

To circumvent this, get a JB3

you are not the only one with Procede getting code 30FE Overboost... send a mail to shiv.

enrita · 08-17-2009, 08:00 AM

did you try to set it at 75% and see if its still triggering it?

DId you try emailing Dustin? He usually handles some of the tech support issues if shiv is unavailable...

That will positively set off the 30FE--80% appears to be the threshold number...

Do you have an oil cooler and upgraded intercooler? Both might help you here.

munters · 08-17-2009, 10:52 AM

Or the Support Form on http://www.vishnutuning.com/tech_callback.htm
Is usually the quickest way.

Mine had the stock ZSP oil cooler and intercooler... given the crazy weather here I feel a FMIC upgrade is not far away

Any recommendations?

Thanks mate. I sent Dustin & Shiv a nice and thorough email. Fingers crossed I'll get some sort of response--if not I'll resort to the blind form. Appreciate the pointers!

OP: I responded to your email. I think it has something to do with the wastegate work your dealership did... I explained this in the email.
