Per Gear Max Requested Torque for 08+ WRX, 09+ FXT

I played around with this a little bit tonight. I left the A table alone and mapped the B table to 460 for all columns of 1st and 400 for all columns of 6th. My sport sharp map targets 460 at WOT. I went WOT in 3rd, 4th and 5th. The requested torque values were 436, 424 and 412 respectively, just as expected. I also saw wastegate duty cycle targets lowering per each gear as expected.

Everything seems to be working as expected so far. Tomorrow I am going to shift my boost, throttle and wastegate tables around and see if I can start taking advantage of the new tables.

I'll post my results and findings.

Thanks to those who contributed to getting this mapped out!

How do I update definition for ecuflash?

For which CAL ID?

I did a couple logs on the way to work today and found that in sport # and 6th gear, my requested torque was at 412 rather than 400 as I expected. I haven't checked 1st or 2nd gears yet. I expected to see: 1st: 460, 2nd: 448, 3rd: 436, 4th: 424, 5th: 412, 6th:400.

3 - 5 were correct when I checked last night. I am not sure why 6th was being limited to 412 rather than 400.

In the EcuFlash def files...
For AZ1G101N add these lines before the line containing "Rev Limit (Fuel Cut)"

Code:

  <table name="Requested Torque Limit A (Per Gear/Engine Speed)" address="0xdd470">
    <table name="X" address="0xdd418" />
    <table name="Y" address="0xdd458" elements="6" />
  </table>
  <table name="Requested Torque Limit B (Per Gear/Engine Speed)" address="0xdd588">
    <table name="X" address="0xdd530" />
    <table name="Y" address="0xdd570" elements="6" />
  </table>

For AZ1E400U edit the AZ1E400C.xml file as follows:

Code:

  <table name="Requested Torque Limit A (Per Gear/Engine Speed)" address="0xdd440">
    <table name="X" address="0xdd3E8" />
    <table name="Y" address="0xdd428" elements="6" />
  </table>
  <table name="Requested Torque Limit B (Per Gear/Engine Speed)" address="0xdd558">
    <table name="X" address="0xdd500" />
    <table name="Y" address="0xdd540" elements="6" />
  </table>

You will need to have this 32BITBASE file so EcuFlash can display the tables.

Appreciate the help, update works just fine.

Recently been using ecuflash due to its checksum.

I hope to be adding checksum recalculation to the next release of RR Editor.

2010 wrx usdm doesn't display properly, and i notice it's the same as 2009 wrx
is that correct?

It is correct and displaying properly for me. It will be the same location as the usdm 2009 wrx.

I had a chance tonight to tune a 11 STI and found some interesting data.
I set up the tables 1st gear at 500 and 6th gear at 400
The gears worked out to be this:
1st 500 requested tq
2nd 480 requested tq
3rd 460 requested tq
4th 440 requested tq
5th 420 requested tq
6th 420 requested tq
neutral 400 requested tq
I set up wastegate duty columns for each gear and was able to control boost by gear.

I also confirmed that Requested tq limit a is for sport and requested tq limit b is for sport sharp

Just one question:
[OT:]
per Gear Max Request Torque at a gasoline engine will reduce the driver´s wish..

At Diesel, there is also a gear dependent limiter, witch limitates the injection amount, instate of the torque request..

The overall function will be the same, the results to other functions can be different:

For this I ´ve got a question:

is the boost requested (injection amound input of boost map) via driver´s wish, or via final allowed injection amount ?

So does this limiter have an effect of the requested boost ?

Just to share this is how I set up the wgdc and rq tq maps for the sti

Have you tried using 98 wgdc for column 500?

Well it was set at 98% for max wgdc. Logging it showed it was running 98% through 1st.
