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

eminehart · **Posted:** Wed Mar 09, 2011 8:56 am

I just found the Per gear Max requested Torque Tables For the 08 WRX and will try to update with the rest of the locations for the other similar roms at a later date.
This table keeps a stock 08 wrx from going WOT till 3600 RPM in 1st and 2nd gear. In theory, It may be able to be used to have Per Gear WGDC's initial and max.
There are 2 tables, A and B, it appears that only A is used though.

Table Description Code to be placed in the 32BITBASE:

Thanks for digging this up. Have you plans to test this in some form or fashion?

rtbrjason · **Posted:** Wed Mar 09, 2011 3:00 pm

Nice find. Hoping this is available on other 08 roms as well.

eminehart · **Posted:** Wed Mar 09, 2011 7:02 pm

I tested everything out and it works flawlessly.
First off, here is my cars setup. 09 WRX, 08 ECU image, DP, Intake,Grimmspeed 3 port, 1000cc's running e85. I am also at high elevation, Denver metro, about 5400 ft.
I did actually set up a tune to take advantage of the tables and gains are had in 1st and 2nd gear.
1st gear has similar spool(0-100rpm) but more boost above 5200 rpm and actually will hit target boost from 5400 RPM to redline.
Boost is up about 1 PSI in general at higher RPM's

2nd Gear has slightly quicker spool(100-200rpm)and hits max boost for this map at 21 PSI by 3700 RPM, and hits target boost from 3700 RPM to redline. Boost is up 1.5 PSI in general around 5000 RPM.

3rd Gear hits max boost around 3400, just for reference.

I was hoping for a little quicker spool from the increased WGDC but I will take the extra Boost on the top end anyday. Can't wait to play with this on some of my customers bigger turbo cars.

By "taking advantage" do you mean fine tuning the values or setting the entire table to be the max?

eminehart · **Posted:** Thu Mar 10, 2011 12:21 am

By take advantage, I mean tweak the map for individual per gear WGDC's. I had previously gone around this table by reducing requested torque below the limits of this table.

1st gear was set to 90% 2nd gear had to be tweaked a bit. First try hit 24 PSI at around 70% WGDC.

Looking at a JDM STi AT ROM right now and the table is 2x16. Gears are 1 & 6 while RPM is the same as you list. The table values are all set to 500 in both tables. So it would seem this may only be used in MT cars. I'll keep looking as I go...

eminehart · **Posted:** Thu Mar 10, 2011 5:25 am

I just added the 09-11 USDM WRX codes

I took a look at the USDM 08 STI 6speed and saw the same thing. This must be a wrx thing. I took a look at an 08 Legacy Spec B and found 6 seperate 2D tables 1*16.

dschultz · **Posted:** Thu Mar 10, 2011 2:20 pm

I'm finding the newer Legacy code is not the same a previous ROMs. It's like they use it to test out new routines in production.

Nice find, Eric!

Nice. With this there is no "need" of running a MBC ... people here say with a MBC 1st and 2nd gear are better, so a lot use a MBC instead of the electronic adjustments... by the way, did you get my PM?

eminehart · **Posted:** Thu Mar 10, 2011 9:02 pm

Thanks for mentioning it. I hadn't seen the PM yet. I a.m PM'n you back.

I really can't wait to see what I can do with a bigger turbo with these tables.

Nice work,

Can you explain how i can get this to work on my ECU defintions or can you upload a file that i can use which will allow me to edit these values in RR??

Do i paste the code in the section for my ecu, and what is the table decription code for, where do i place that is it in the same .xml file or somewhere else?

Sorry for being a newb but i would really like to try these new tables on my car.

Thanks,

eminehart · **Posted:** Fri Mar 11, 2011 12:17 am

The top section of the ecu definions has the tables and desriptions. You will place the first section there. Then you place the second part under your individual ecu. I noticed you have an aus rom. What ecu do you have. I will set up the table for your ecu.
