@MartijnFeekes I agree, the ECU still gets hot when you turn the engine off after driving due to heatsoak but I think it definitely helps. Some people mount it somewhere else but I heard the ECU gets hot so the air going through the intake helps to cool it down while the car is running. Either way the heatshield is better than nothing
The principle was good because apparently they wanted the ECU to be cooled when running, but the long term consequence is bad. The heatshield doesn't make a huge difference but any small amount helps.
That's probably not a bad idea, I know some people have made brackets to relocate it on the firewall without having to mod the cables but yes I would definitely put a fan on it if it was moved off the plenum because the plenum helps to cool it during operation
We're trying to sort that out as well. Another GTA owner from NZ is making an extension loom to relocate the ECU into the cabin for his 147 GTA race car. Will try and see if that's feasible. People online have said not to relocate the ECU as the plenum helps to cool it down during operation, but I actually don't know how accurate this is. If someone can find the ECU plugs for sale we can actually make a plug and play relocation kit!
wow this is a really nice idea, well done sir.
Thanks! Made one for my 3.2 GT. I don’t think it prevents heat from the engine block, but hopefully from the manifold/cat.

Very good idea. Stupid why they take the ECU from the inside of the car to the engine bay. Thanks for sharing.

How about relocating ECU in footwell and getting a small computer fan wired in next to it to keep it cool

Hey mate great video, did you have any update on temperature decrease?
@J27M haven't measured the difference but definitely helps after switching the engine off, the ECU heatsoaks slower off the engine's residual heat
Good old number 8 wire mentality! Shame you couldn't show the difference in temps with a temp gun or similar.
I'm planning to do some testing this summer
how about ECU relocation?

Fantastic idea and help. Would you by any chance have the dimensions for the template? Thank you for this inspirational video.
Didn't keep the dimensions sorry but if you take your ECU out it's very easy to draw up a rough template
@@LueysGarage Ok pal will do thanks again. :-)
