• Escort mk7 ECU swap 28 Jun 2007 (Forum)
  hi, me and a friend have recently swapped the engine in my 1999t escort from a 1.6 zetec (snapped cambelt, uneconomical repair) to a 1993k 1.8 zetec 105ps (free donor car that ran perfectly) the car runs rough with the original ecu (assumed mapping/lean mixture etc). the problem we've encountered is that due to the 1.6 ford immobiliser we don't seem to be able to start the car using the original 1.8 ecu, so the question is : when buying a second hand 1996 onwards immobiliser-compatible ecu (ebay seems to have some) will it need to come with any ther kit for the immobiliser (compatible transponder key etc) or can it just be plugged straight in and started. i've searched the web but got no straight answers.
• Vauxhall Vectra C - [Vectra C] [02-03] How to change/replace Airbag EC 14 Dec 2013 (Forum)
  I managed to find a group of local Airbag ECU engineers, who will probably to this for £60. But, I can try it myself if its just a matter of removing the existing unit and replacing it. Trouble is that I don't know where the airbag ECU is fitted and how to get access to it.
• Mondeo TDCi ECU updates / warming up 23 Mar 2012 (Forum)
  I had come to the view that it was approx end 2002 to end 2003 models that were worst effected by the ECU issues, and that earlier and later cars were OK. I wonder if I should ask the dealer to reinstall the earlier ECU software? Does anyone else have a similar experience? Regards.

• Merc E220 W124 ECU 25 Feb 2002 (Forum)
  Our local Merc specialist changed the throttle body (300 quid), still no joy, he now says that the diagnosis computer points to the ECU (1000 quid). He also got a merc engineer to look at it. We have referred HJ's FAQ in the process but the problem seems to be different. Is there a way of avoiding 1000 quid by re-conditioning the ECU or getting an exchange unit.
• Toyota MR2 - ECU light 29 May 2017 (Forum)
  Hello. Can someone please advise me what it could potentially mean if the ECU light doesn't come on at all? I am used to the light coming on for a few seconds and then going off when starting the vehicle. However, with no obvious cause, the light doesn't come on at all. The car is a Mk3 MR2.

• ECUs 14 Oct 2001 (Forum)
  With all cars nowadays having ECUs what do you independant garage owners or mechanics do when you need to diagnose engine or other faults. Is there such a thing as a common diagnostic tool which can be adjusted to suit the paramaters of all cars, or do you have to take customers cars to main dealers with the manufacturers supplied equipment.
