If your using winols, what’s the map ID your referencing?

ip_tq_pow_max_at
ip_tq_pow_max_dct
ip_tq_pow_max_mt
ip_tq_pow_max_at_4wd

Quick update - I was able to find torque limit maps by gear in SIMOS8.4 bin file (D, 0003). One thing of note - it seems like there's only 4 of these there, and they align with MT/MT_4WD torque limit maps in SIMOS8.5. I didn't see anything resembling SIMOS8.5 AT maps. Regardless, I was able to modify simos8.4 torque limit maps and saw torque as high as 517Nm produced which is definitely not stock. I couldn't log it well since Eurodyne logger didn't want to save the log to file for me. I'll try to figure out another logging solution and maybe will post my xdf file.

I have a logging solution for simos8.  Pm me for licensing infos.

ip_tq_pow_max_at
ip_tq_pow_max_dct
ip_tq_pow_max_mt
ip_tq_pow_max_at_4wd
yes, but I couldn't find ip_tq_pow_max_at, ip_tq_pow_max_dct and ip_tq_pow_max_at_4wd in simos8.4 binary. I only saw maps similar to ip_tq_pow_max_mt and ip_tq_pow_max_mt_4wd, so that's what I changed as you can see in from the bin/xdf (plus boost pressure limit). That said, this still might need to be refined a lot. Another note is that a mile after the pull (driving at very light throttle and low rpms), the car just shutdown and threw a bunch of "no communication with ECU" codes and doesn't restart even after flashing back to stock. While the current diagnosis is that this is likely an ECU power supply relay from this tsb https://static.nhtsa.gov/odi/tsbs/2014/SB-10055713-5611.pdf, it could be anything until I get that relay and it fixes the car.

ip_tq_pow_max_at
ip_tq_pow_max_dct
ip_tq_pow_max_mt
ip_tq_pow_max_at_4wd

In that hexdump area of simos8.4, I edit those along with:
ip_tq_pow_max_drof_mt
ip_tq_pow_max_drof_mt_4wd
ip_tqi_dif_abs_lim
ip_tqi_dif_abs_lim_st
ip_tqi_dif_i_lim

Fyi, if your car is a DL501, your not going to generate more than 550Nm. The DL501 will limit the power delivery regardless of mods done to engine. You could overcome by under valuing the power over CAN but I've never found it to work 100% on my car at getting the full power available, unless the DL501 is programmed for the extra power allowance.

great, what do those drof maps do as well as ip_tqi_dif_abs_lim* and ip_tqi_dif_i_lim?

ip_tqi_dif_abs_lim
ip_tqi_dif_abs_lim_st
ip_tqi_dif_i_lim

The above are for limp mode power limits which I believe when triggered are active above 1500rpm. You don't need to edit these maps, but I do and max them out. I do my fair share of tracking and would not want throttle/power cut when I'm committed in or out of a corner.

ip_tq_pow_max_drof_mt
ip_tq_pow_max_drof_mt_4wd

The above from my understanding are for manual trans and/or free reving. However, a large amount of the ecu's I've worked on will use manual trans tables even on an automatic vehicle. If the manual trans maps are below the limits of the automatic maps, the manual map limits "could" restrict the final output power because those values are the lesser in the batch of torque maps and viseversa.

I have 2x A6 3.0t , one is an 2010 with 4FI910551D 0050 (TUNED) The other is a 2009 with 4F1910551A 0050 (STOCK) both CCAA.
Are the files vastly different or even compatible? if anyone knows.
I have tactrix 2 and pcmflash is coming tomorrow.

Thanks.

Yes, you could in theory also update the 2009 file with D variant frf and then flash with just the map calibration addresses edited.

However, you can’t do an actual read with simos8.4 with pcmflash, it’ll kick out a virtual read. The only tool I know that does an actual read through OBD is Kess, but you need to unlock OBD reading in boot mode first. That actual read would get you all in the map calibration addresses.

If you need a full read, only option is to bench, only tools I’m aware that bench are Autotuner and bFlash. Once read with one of those tools, you could view the full read by looking at the original backup file.

Thanks for the reply, I think mine is Simos 8.3 if that makes any difference.
Pcmflash pdf says it can read and write, I was hoping to extract the tuned file and flash it back to my other ecu that is stock.
I've done plenty of Motronic stuff but know very little about Simos.

Pretty good marketing they are doing, but MagicMotorsport can as well, and it's a much bigger tool.
For Simos8.3 you either have full OBD protocol or not. If there is full OBD you need a dump and then that can be written OBD with RSA bypass.
If there's no full OBD protocol, and no RSA bypass implemented, then it needs to be set into devmode in bench or boot mode first.

Reading is impossible regardless until it's in devmode.

Pcmflash say it does a virtual read for simos 8.3 and 8.4 , does that mean it downloads an exact copy from pcmflash server?

Attached my xdf and bin file, I couldn't edit my previous post to add these files. This is all WIP and very raw.

Do you think this will be similar to 8.51?  Mainly I'm looking to disable the SAI

Post your file and I’ll see if it’s similar to 8.4, to disable SAI
