Getting past the 30.1 PSI limit...94170715 ROM

Hi, so I am trying to get around 33-35 PSI on FP RED. Build link is in the sig. In ECUFlash, the load limit sits at 159.7 and PSI at 30.1, can't figure out how to get it past that. 0715 on the 8 ROM. I thought there was a table to adjust that. However, I can't seem to find it. What am I missing?

Thanks in advance.

Are those the (2) tables with addresses @ 26592 and 26694, AirFlow and FuelFlow limiter eliminator patches?

My load seems low at approx 270 as the highest in a 3rd gear log blowin 29 PSI...

Which table's load/psi limit are you referring to?
Main Boost Desired Engine PSI.

Bump for previous post.

Also, does this desired load seem low with these settings?

Ok, it states to activate them to set them to 0x9...

What are the other 3 bits changed too? Does this look right: 0x9000?

Also, has anyone changed the Load scaling from Load 8 to Loadx1 for the Boost Desired Engine Load?

You should have a boost adder table that you can use to get around the limits of the BDE tables. The boost the ECU will target is boost adder + BDE, so if you want 10 psi more than what the BDE table allows you to have, just set the boost adder table 10 higher than it currently is, along with the BDE table maxed out.

Thank you for the post, however, that seems like a bandaid patch. No way to do it legitly?

That is the "legit" and only way to do it.

Really? I''m not discrediting that it may be a way to do it, but I would like to here from some tuners like Arron, Merlin, Jaimie, etc. I swear I saw another way to do it back in the day. So you could run the boost adder at what it is supposed to be for elevation.

HaHA, Yes, I know how to do hex editing. I was just curious if since in my tuner def, it said 0x9 is what to enter, I was assuming that it needed to be 0x9000 to be correct.

Thanks for the due diligence.

That is the "legit" and only way to do it.
So I reread the ECU Based Boost sticky, and you are correct, that is the way you do it. So for the hesitation and questioning. Thanks for the post again.

Are you referring to the one I wrote by any chance (linked in my sig)?
