More RB25 alternatives (A31 Cefiro ECU, ECR32 RB25DE ECU)

[Matt]

A31 RB20DET - RB25DET maps + TPS trigger firmware (use updated address file to access parameter)

ECR32 RB25DE - RB25DET maps (uses variable voltage TPS limp mode due to missing TPS trigger switch same as Z32 ECUs)

Attached are updates for RB25DET ECU alternatives in addition to the Z32 and R32 ECUs on our website. Both of these are straight plug in alternatives but with no VCT output, so an external VCT controller (RPM trigger switch) is still required

A31 TPS trigger voltage is set at 900mV default and is adjustable using the attached address file

I've performed code inspection and testing for the Cefiro ECUs and found no problems with fluctuating injection times as previously reported by a customer so I will continue to support these ECUs with our Type 1 boards.

Please note that special Xilinx programming is required for Type 1 boards using these ECUs in order for USB communications to work properly. We require instructions specifying A31 Cefiro / J30 Maxima are required when ordering boards to use in these ECUs

Default Xilinx memory map location is F700 on Type 1 boards which covers most ECUs, but on Cefiro ECUs it is F600/E000 and J30 Maxima E000 so those need special programming. Refer to our Technical bulletin regarding this

Does NA RB20DE ECU ok ?

[Matt]

Ceffy ECU? Yeah should be the same. I've only completely went over the RB20DET one which you can load the ROM image into an RB20DE ECU
