Lightbulb How to increase Boost Limit past 319 load
Hi folks.

Here's a little something if you don't like hitting "319" ceiling on Boost Limit.

Originally posted on EvoX... now put up here too.

This patch tells the ECU to double the load-limit lookup value it's getting from the existing "Boost Limit" table. Plus, to see the "correct" value on-screen in EcuFlash, we're looking at that same table via a new scale.

Note that this doesn't raise the OVERALL load-calc ceiling (360?) - it just lets you retain a usable boost-fuel-cut system if your load sees values over 319.


If your ROM isn't covered here, just shout and I'll add it.

    <data name="Patch disabled" value="5942" />

  <table name="Boost Limit Rescale Patch (F1 for Help)" address="198bc" category="Turbo Boost Limit - Rescaled" type="1D" scaling="BoostLimitRescalePatch" description="Once ENABLED, the [Boost Limit - Rescaled] table replaces the original [Boost Limit] table.  Maximum load will then be able to exceed 319."/>

  </table>
Here's what it will look like on a 100% stock ROM, with the XML patched in ahead of the regular "Turbo" section:





To use, under the new "Turbo Boost Limit - Rescaled" heading...

- Increment the item "Boost Limit Rescale Patch (F1 for Help)" to "Patch ENABLED!" (use '+' or ']')
- Set your desired load-based boost limit values in the new table: "Boost Limit - Rescaled".
- Completely ignore the old table: "Boost Limit"
- Enjoy!


Cheers,

Rich

While I have to rescale on the MR's for lower load to keep clutchpacks happy, this is a nice update especially for GSR's and big turbos. Great work!
