Anybody for AZ1G401V? Running Merpmod Switch looks like I can change "Engine Load Limit A (Maximum)" to 5, but "Engine Load Limit B Maximum (RPM)" maxes out at 4.

Thank you.

Code:

ROM:00095F5C Engine_Load_Limit_B_Maximum_RPM_Multiplier:.float 0.000061035156

Works! Someone should def put that in the official definitions!

Pushing around 4.6 peak load right now. Multiplied that table by 4.

Hi guys!

Will tune this 2018 Final Edition tomorrow and he's installed a Precision turbo and is hoping to get close to 500 hp - so load limit B will come into play.

Can someone please see if you can find that map in the attached rom?

AZ1S000G

Cheers
Patrick

Silly question... but you wouldn't happen to know what address the fuel cut map is at? My ecuflash defs is incorrect.

edit: made myself this table... seems ok, or what do you real hackers say?

<table name="Boost Limit (Fuel Cut)"
address="d0278">
<table name="Atmospheric Pressure"
address="c0fe0"/>
<table name="Engine Speed" address="c0ff8"/>
</table>

<table name="Boost Limit (Fuel Cut)"
address="d0278">
<table name="Atmospheric Pressure"

<table name="Engine Speed" address="c0ff8"/>
</table>

That should be it, then:

Code:

   <table name="Boost Limit (Fuel Cut)__" address="d0278">
      <table name="Engine Speed" address="d023c"/>
   </table>

Also make sure your 32BITBASE has the table definition:

Code:

   <table name="Boost Limit (Fuel Cut)__" category="Boost Control - Limits" type="2D" level="4" scaling="psiabsolute2">
      <description>Fuel cut will be activated when actual boost exceeds the corresponding threshold in this table.</description>
      <table name="Engine Speed" type="X Axis" elements="15" scaling="RPM"/>
   </table>

I've gone through the logs on my 13 sti. I'm hitting 3.32 g/rev as max load, although I don't really remember the circumstances. Is it recommended to raise the limit anyway?
It's for AZ1L100G

Hope somebody can help, I already doubled the multiplier

Changed the Engine Load Limit A Maximum A

But the Engine Load Limit A Maximum B RPM didn't change. I'm hitting 4 g/revs and having issues with rev limits.

Is there another parameter that I have to update ? My ROM is AZ1S000G with DimeMod.

do you have a log of this happening you can post up with your rom? the load limit and rev limit are usually 2 separate things?

Yes I have a lot of logs, in any of them, the car went higher than 6300 RPM, I did several adjustments and no luck. I'm suspecting spark plugs, fueling issue or boost cut / ewg malfunction. Then I found that Engine Load is capped at 4 g/rev, I wanted to give it a shot. I'm running full SD.

I can share logs and rom by private msg.
