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.

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

- Completely ignore the old table: "Boost Limit"
- Enjoy!
