To turn off SAI you need a switch. Simos 8.3 is so different from 8.5 that you will find it hard to find.

haven't posted here in a while, I ended up needing to replace the engine - driver side bank SC IC started to pour the coolant in the cylinders, and the engine hydrolocked. When I bolt everything back up (and as usual, being held up by small parts and details  I hope to continue playing with this ECU. Very curious about what needs to be changed to turn the SAI off and whether switching it off will make some monitors not pass the readiness tests. |

Hi guys,
I have a question on tuning for E85, I see the scalar Constant for stoichiometric air/fuel ratio (=1/14.7) (c_mff_fac) is set at 0.0680 for gas .
If I change it to around 0.0940 for E85, would this work with the stock injectors?
Thanks.

For a pure E85 0,1 will be better.

Thanks for the reply, I'm running a single pulley and want to go with the dual pulley setup soon, I have read that I will run out of injector using E85 and would need an HPFP upgrade to give it more fuel, I'm used to swapping out injectors on my older builds, LOTS to read... |

Yes. For dual pulley and E85 you need hpfp upgrade, but maybe E40 will be enought? Then you don't need new pump with upgrade.

Anyone with a simos 8 Damos they would like to sell, let me know.

You do not need these maps. This is not what you think. Maps names: Map controller P gain for stationary operation, Map controller D gain for stationary operation... etc.

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.
Hello I found a local version S4 DL501 with a 440NM torque limit... |

Yes you can find a lot of ip_tq_pow maps at 440Nm, same with the DROF speed maps at 500Nm. Although if editing Simos8.4 paired to DL501, you’ll need to edit the DSG maps. Sent from my iPhone using Tapatalk |

The gearbox torque limit is set to 440NM. So if you do not change the gearbox limit... |

When downloading virtual files off the PCMFLASH server, can you flash the latest revision of your software or do you have to stick with the original?, mine is 3 revisions back in the list.
Probably would need a full read..

On other platforms I have flashed the latest version with PCMFLASH. I am sure it is possible with the S4 also. |
