James. 7 Posted March 2, 2023 Time. A commodity I have little of. But certainly food for thought. I’ve despatched the ecu to a repair specialist, so will have a clearer idea of next steps in a few days. Quote Share this post Link to post Share on other sites
fla 9 Posted March 2, 2023 just in terms of how i spaced the time on doing the loom on mine - it was stuck in a big box in the kitchen for months. But come the Christmas holidays i though i would unwrap and make a start. I did a few hours per weekend - a fair amount of time is just untaping it and making sure the plastic support pieces are not lost, whilst keeping the shape roughly correct. It took about 3 weekends but if i were to have sat down and put a complete weekend aside it could have been done. Then re-wrapping, and knowing your high standards James, this will be more than a little time consuming, ensuring the bends are correct and as close in shape to the original as possible. So its doable in bite-sized time slots, as long as the car is not being used. Quote Share this post Link to post Share on other sites
1xshaunx1 27 Posted March 2, 2023 When I was looking into OBD2 and looking at other peoples threads, they were upgrading components to fit the loom and it looked a bit much, if you change a load of components, do they all work as they should, which ones don’t? Vince did it so oe sensors and parts were useable. So it looks oe and spares are Corrado except throttle body. Obviously his cost was a substantial amount, but it didn’t require a raft of new stuff because of different plugs and he’s done it before and can get an immobile nightmare going reliably in no time once in shop. Like you say if you are time rich things are a little easier. It would be nice if there was something wrong with the ECU and they fixed it cheap, but unfortunately that’s not in Corrado DNA but we all live in hope 🤞 Quote Share this post Link to post Share on other sites
fla 9 Posted March 2, 2023 i had to wire in the aircon which was a bit tricky, but Neil (Science) helped me out with that. Otherwise the only other thing i would have left in were some of the earth wires, which can be useful. Other than that, it was just the wiring for the throttle body, immobiliser and maybe a few more things that i cant remember! I needed to do something for the immobiliser too, and the maf needed changing. Also, the main connector had to have some wires depinned. This was fiddly - removing these from the golf connector and putting them into the corrado one. Quote Share this post Link to post Share on other sites
James. 7 Posted March 11, 2023 (edited) For purposes of “the next person”. I thought it important to update this thread. 1, I contacted “ECU doctor”. They said they couldn’t help. 2. Sent the ECU to “ECU testing”. They opened it up and returned it as they couldn’t create a testing rig. 3. Sent to “ECU technologies”. Not expecting anything, they initially said that they’ve fixed them before and should be able to fix it. Received it back this morning (£250 lighter) and sealed up with a 2 year warranty. The main upside is that I wanted to know “why” it went faulty (to prevent it happening again). Looks like at some point I’ve reversed the polarity to the ECU and fried the earth track (the burnt components must have been a type of diode). Which isn’t surprising considering I spent so long tidying the wires under the dash. I’ll leave it with the garage on Monday and hopefully be able to update the main thread soon after. Although the first two companies couldn’t assist. They were good enough to get back to me promptly and not have me flailing in the wind. Thanks everyone for all the help you’ve offered up.

Dox 22 Posted March 11, 2023 Well done for perseverance, I think I'd have given up after 2 refusals personally. Make sure the battery / chassis / engine earth is perfect as that's known to divert heavy cranking current through ecu via sensor earths frying ECUs when missing, broken or high resistance.

I’ll be treating it with absolute care an attention. And thanks for all your help/guidance. I have the utmost faith with the garage it’s currently with.
