I was talking with the owner of Haltec yesterday and we were going over the ECU and the horrible design and location in the engine bay. He was saying that the location will absorb all the heat after a pull and with the added heat of a tune and all that crap they were shitting ECU's. Some one should look into making an ECU extension to relocate the ECU into the cab.

all the 1203984095 wires you will make extension for? good luck!

Attach heat dissipation fins onto the ecu.

Fins in a hot area without air flow across the fins will adsorb heat rather than dissipate it.

You are correct. I would be surprised that the engine compartment has areas with completely still air while moving.

there are tons of vehicles with ecu in the engine bay and I never heard anything bad happening to them.
gens have it like that and nobody Said their ecu screwed up after all the mods plus a tune because of heat.

Mechanics, or whoever "he" might be, are/is not mechanical engineers nor physicist. If he thinks it will happen, and he runs across a situation as such mentioned, then please do tell. Otherwise, he can think of whatever he wants. Until I hear it on here or any other Hyundai forums I will not worry about it.
When I was getting my degree in electronics and computers, I remember them saying must electronics have a high temp tolerance. And I am more than confident (not even worried about it) that when the engineers were making these ECU's to spend its life in the engine bays they kept heat and water being a factor in its everyday life in mind as well.

Just run a line from the radiator to it LOL
Even that in reality will make the ECU hotter than it already is.

lmao!!!
"he" is the OWNER/Lead engineer of Haltec. Ever heard of them? He might know a thing or two about this shit. But whatever. I am just trying to be helpful. Burn your fucking ECU up. I don't care.

Calm down. Perhaps you can clarify your original post. Were they experiencing heat issues with the VT and the position of it's ECU and were having to replace them or does he think that this is going to be a problem based on expected heat load and ECU position but has not seen any actually fail due to heat stress.
In the Gen turbo they are actually heat soaking them to the point of failure. The stock one did it and theirs in the same place did it. Standing still after a pull raises the temps to above 80 c and the electronics shut down or malfunction. Their solution was to move the ecu inside the cabin

There is a significant difference in the engine bays of the two cars. Most notably the orientation of the motor.
Our motor is far to the side away from the ECU. The geni as a longitudinal mount puts the center mass (and thusly the heat) much closer to the ECU.
Also due to our engine bay we have a (relatively) huge void space right ahead of the ECU that allows for air flow.

OH OK well if "he" "owns" or is a "lead engineer" of "Haltec" then tell his ass to make something for us "non-engineers" rather than saying "your ecu is going to burn up because of ALL the power it is going to put down". Actions speak louder than anyone word and I have yet to see a problem with peoples ECU here. So he can say all he wants about anything but until I see proof, the ECU will be fine. I am sure the Engineers at Hyundai know WAY more about their vehicles than he does. Does he even own a VT? Has he ran logs on the VT temps?
until I see problems from other people, I will not worry about it F'ing uo my ECU. And I am sure when it does became a problem there will be a plug and play ECU extension product coming out by socks or kyle or anyone else who cares/knows more about our cars then the owner Haltec. Tell him thanks for his 2 cents though.
