Which Ecu To Get; R34 Gt-t Tiptronic

[Sydneykid]

looks like companies are getting lazy when it comes to autos

Nothing to do with laziness, the Nissan ECU programming for lift logic is EXTENSIVE. Think about how much data and calculations are needed to be done to cut/retard the ignition just the right amount to give a smooth change and limit the torque loadings while still giving reasonable performance. Up and down hills, around corners, in reverse and 4 forward gears, with limitless throttle opening positions and load (how much weight is it carrying). There is buckloads of R&D and testing needed to get that right, Nissan spent $millions. All of that has ot be paid for, hence included in the price of the ECU.

The REAL question is would you pay $20K for a Power FC than worked in an auto?

Apexi have decided that you probably wouldn't, so they haven't spent the $millions.

cheers

PS; Apexi do have Power FC's for auto Toyotas, but their shift logic is in the auto ECU not the engine ECU.
