Questions for GTR33 tuning

Post by familyhorse » Sun Jul 11, 2021 1:48 am

I would like to look for quick answer to the following quesions concerning the GTR33 (RB26) tuning:

1) How to select which cells to do autotune and which are excluded;

2) Apart from the fuel map and timing map, what other tuning functions are related to sudden acceleration;

Thanks so much.

Hi Rigo

1. Section 26 covers the auto tuner
https://www.nistune.com/docs/NIStune%20 ... Manual.pdf

This feature was added on customer request, but we don't normally use it and don't recommend using it except for fine tuning (ie all base mixtures etc should be setup firstly)

You can only adjust the RPM cut off (below RPM) and TPS adjustments. You cannot select which cells are auto tune enabled (or not)

2. Mapping guide (page 34)

Some accelerator enrich/Wall flow are available for BNR32 RB20DETT ECUs
