SR20DET in S13.

So this is the first time I tune using the Nistune software and my 4th Nissan ever. This was literally dead easy,
Owner swapped to bigger injectors and larger MAF. After using the software to compensate for that I tweaked the K constant and latency until I was getting steady 14.7:1 AFR when the map says 14.7:1.
The scalar is off a bit at at higher load the mixture in the table was not coming out right but I didn´t want to bother with fixing the scalar so I just tuned to the afr´s I wanted and disregarded what was in the fuel tables.
Sorted mixture around 0kpa and in transition although admittadly I could have taken more out of the accelaration enrichment then I did.
Didn´t do dyno this time as we where just doing a shakedown of the engine swap and things.
Will post up a dyno graph when it´s all dyno tuned.
I can´t for the life of me find a picture of the owners car. But it´s very well specced drift car.
I think I´ll be installing and tuning quite a few of these nistune boards in the future
