Skoda Octavia II (1Z3) – ECU remap v5.xx

The more I study Bosch manual and various books from real masters the more I see how commercial chiptuning fucks up dumb customers. Of course it is evolution of version 4 series with improved knowledge and more precise calculations. This is history of version 5 series of ECU remap.

PLEASE READ WARNINGS BEFORE YOU PROCEED !!!

SUMMARY

the more I know the more I see how commercial chiptuning is joke
I am also glad I grew balls and took the risk with ECU calibration by myself
still problems with overheating
optimizing Pedal/Driver Wish maps
optimizing AFR
optimizing turbocharger spooling for better transient response
optimizing EGT limiter
optimizing injection timing
I finally started some intelligent version numbering instead of unnecessary jumps in major version

screwing around with FMA in hope to increase min. Lambda 1.2 (v5.00)
Pedal/Driver Wish maps to default
Pedal increased fueling at 40-60% position (v5.10)
Torque Limiter – increased fueling @ 2000 rpm
duration maps interpolated for 70mg IQ
Lambda maps returned to default, increased only at high revs (v5.11)
FMA min. fuelling returned to default (it doesn’t work – possibly somewhere parallel maps)
MAP Smoke Limiter – allow more heat at low revs for quicker turbocharger spool (v5.12)
MAP Smoke Limiter – reducing AFR at low revs for quicker turbo spool and slowly increase AFR for optimal combustion process and less overheating (v5.13)
Lambda maps returned to default
Torque Limiter – slightly increased @ 1750-1900 rpm (factory clutch is rated at 400Nm)
SOI maps optimized for increased fueling (v5.2)
Torque Limiter – values used from Skoda Octavia vRS (uses same clutch)
SOI maps reduced/retarded due loss of power (v5.21)
racing style Pedal/Driver Wish for quicker engine response (v5.22)
SOI maps advanced 0.5° (v5.23)
EGT limiter returned to default due overheating and turbo damage (v5.24)
MAP Smoke Limiter – AFR 18.5:1 at engine speeds <3000rpm and 19:1 >3000rpm due overheating
