Great Service. 5/5

Had great service from ECU Testing LTD I sent the ECU to them and they turned it around really quickly ,and let me know what was happening at all stages , I fitted the unit back on the car no problems and it's been fine since ,this was plug n play no codes no software necessary I recommend this company to anyone having ECU faults it's worth the money , don't mess with scrapyard second hand units only to have the same faults and no warranty.
