Denso Nissan adresses

by **jurebv** » Fri Mar 09, 2018 9:45 am

Since there is very little or no info on this ecu, maybe i can start by posting some adresses

This is file I found from this forum under "original ecu files" section, navarra 2,5 dci cr 126kw

what i found out at first glance:

- Map data is 16bit HiLO
- Map Axis are 32-bit Float HiLO

included mappack (can't really call it mappack lol) but still missing factors/offsets

also indentifying maps is a problem because of a missing factors

Its a (somekind of a) start :D

Ok, I've got a "pro" tuned file,

In attachment is ORI & TUNE

I know it's a precentage tuning but it's a start.

If anyone can contribute with some factors , offsets or map it would be great to finaly solve this ecu's mystery

Most of the maps i posted in first file tuner edited with precentage but I am most interested at changes from adress FFB88

Best Regards

even without opening your files
FFB80+ don't matter you can ignore that mods they are done automatically by the software during mods

kennfeld maybe you can share some factors if you are familiar with?

ecm crack is bad on that ecu

better use the original version

I dont use ECM anyway im trying to manually indenify maps but values make no sense because im missing factors

pro tuned file attached :

if anyone could contribute with some factors I would really be greatful

set of maps - Torque to IQ - adress D8070 in 32bit float data and axis before map 10x10 - more like an inverse torque to iq - axis RPM and iq in mm3 - map values = torque in NM

set of maps - SOI - adress BA418 in 32bit float data and axis before map 23x19

MAIN torque limiter - adress A7548 - in 16bit data but axis are before map in 32float 23x5 map- im missing a factor here

another Torque Limiter A79C4 - in 16bit data but axis are before map in 32float 23x5 map- im missing a factor here

Duration map - adress CB7BC - 14x29 map in 32bit float data and axis before map Rail pressure vs IQ in mm3, map values = duration in uS

set of maps - Rail pressure map adress 9B900 in 16bit data but axis are before map in 32float 23x19 map

set of maps - Boost map - adress A2978 in 16bit 18x25 and axis 32bit float before map RPMvsIQ , mbar

boost limiter - A4A88
boost limiter 2 -A4B14
