Did you replace or try to program the ECM?
Customer: replied 4 months ago.
I can't find anyone who can do that locally who has the software to do it. I have spent $300 on software and laptop modifications to try to do it myself but the mongoose JLR still doesn't work.If I remove the ECM can I take or send it somewhere to be replaced or reflashed or does it have to be on the vehicle?I don't want to tow the car across town.

The ECM needs to be in the vehicle to program it. You need the IDS/SDD software. On your vehicle the VCM is recommended for doing any flash programming.
