MSS54HP ECU flash to CSL

[kkkk]

I'm looking at converting to a MAP sensor and CSL airbox
Car currently has a MSS54 DME, but I have sourced a MSS54HP DME. It currently has an Alpha N Tune on it 2ith 8300rpm redline (was running a e36 with S54 Engine swap)
What is the process to make that new ECU work with a MAP sensor? Do I have to send the ECU in or can this be done remotely?

If I was to just plug in the Alpha N tuned MSS43HP, I assume the car would still run? Do I need to do any additional wiring? Would I lose any old settings in the car or would the EWS /security etc not work./ Mtrack mode etc

You need to reflash ECU with CSL modded bin which is on https://github.com/saildot4k/MSS54-X...4HP%20to%20CSL Then if you need to save EWS- shange and code your EWS. Then with Martyn MSS54 tool disable DTCs or other staff that you need, change wires on MAP and IAT sensors and run the car on new ECU. Your options like ews Mtrack and other staff will be wiped. you need it to change again in new ECU.

Yes, but if it was a normal MSS54 ecu you would still need to flash the CSL modded bin regardless?

MSS54 do not support CSL bin, only MSS54HP

Yes, what I meant was can the MSS54HP with an Alpha N tune be flashed to CSL and run MAP?
