You have an auto backup with your ecu, as long as you have not made too many connected changes , your original map should be there from the first time you connected to your laptop.

What exactly happened to your first one?

Well from what we've determined, it pretty much just overheated which led to sudden failure. I'm taking steps to reduce heat in the engine bay. It's been extremely humid here in NJ lately, and between that, road temps in the mid 90s, my black car, stock bumper and stock hood with no vents, temps are pretty ridiculous in the engine bay.

To combat heat I've come up with the following solutions:
-Washer risers under the back of the hood. Yes it looks like dick. Once the turbo blanket comes in, I'll remove a couple washers so it looks flush, as it was actually a little sunken in from the factory.
-I've ordered a turbo blanket for the hot side.
-When I get a little more cash (I'm pretty strapped at the moment) I'll wrap the O2 housing.
-Will cut up my fog housings today for more air flow. (http://www.gencoupe.com/diy-do-yourself/35690-diy-oem-fog-bezels-cai.html)
-I set the engine fan for a lower activation temperature so it's on more of the time.
-I may cut a hole in the wheel well and wire in a computer case fan blowing on the ECU.

Mine freaked out in Tenn during my trip to NY, from TX and it was raining the whole time, lucky I had enough common sense to always carry my stock ECU, and Computer with the Maps on it. I think the throttle lost its configs and then when I tried plugging up my laptop it would try and connect and then cut out, then all my configs were erased. I unplugged it plugged up my stock one and when I reached my final destination the Haltech let me plug up to it. On the way back to TX I used the Haltech and it worked fine. Over here the temps are 100+ so I could only imagine the engine temps but it doesn't freak out. Maybe cuz i still have the stock turbo.

I like your ideas to try and reduce engine temps.

You know, when mine acted up it was in the rain, too. Adam has assured me that the unit is completely waterproof, but it first died in the rain, and second cut out completely and did not let me connect to it. It was very hot, yes, but also just went through a car wash. :dunno:

Car Wash WTF????? weird

 

[danperezsax]

Well it was like 98F in the sun and the car is just idling there for like 25 minutes getting washed and dried. It's no surprise the temps were retarded.

 

[curtisb]

I was thinkin about getting a blanket also but my turbo puts it way more heat an were not that far from eachother like 2hrs its hot hear also but good luck ..i to after hearing about the ecu prob have my oem in the car

hey when do you think you will post a pic of your settings ?

 

[curtisb]

i can in a few mins

 

[curtisb]

this is the timing

this is fuel

Did the carwash today with no problems. LOL. It was after a 5 minute drive, and I turned the motor off and opened the hood instead of sitting there idling.

Good

Update: turbo blanket didn't fit. Gonna order the right one from PTP soon. However, after raising the back of the hood and cutting open the fog bezels, I have not had a repeat of ANY of the idle issues or ECU cut out issue. Not once during that heatwave last week where the ambient temps were 95+F every day, and it did rain some. Looks like a little more ventilation was all she needed.

BTW Treadstone ftw... After a cold start, I cruised for about 30 minutes at 70-80mph and my IAT stayed between 10-15 above ambient. After parking in the sun and running into the bank, the IAT read 55 above ambient, but dropped back down to 20 above ambient in the first couple minutes. It's the first part of my trip today, though, that showed me how effective the added venting is... for most of the time on the highway (out of boost) I saw 86 degrees IAT with 75F outside! Ridiculous! Once the engine bay heat soaked a bit, it was more normal.

Dan,

That is some awesome information to have, I knew that the heat from the upgraded turbo was the issue, we took our stock genesis to Arizona and beat the crap out of it and let it idle in the sun for hours, after the throttle chip got to 140* C, the throttle chip started to act up. With that said, any way to get heat away from the ECU will help tremendously as you have seen.

As for the clutch switch and launch control, I have not forgotten you all . I have been very busy and I am still working on the write up, but so you all know, we now have the clutch switches in stock so that non cruise control cars can just purchase the switch, plug it in, and go!

Anyone who wants one of these switches, just call or email me in the office and we can get you one right away, we will be selling these at a very reasonable $20.00 per unit.

Sometime late this week or early next week I will have the launch control/flat shift write up posted here!

Ragchaos, can you please email me some information about the issues that you had so that I can log them for our R & D team? Please include a mods list so that I have a complete and detailed report to send them. As we have seen, the issues seem to be caused by excessive heat in the engine bay, so I just want to document any issues to show this.

do u think it be worse to let air hit the ecu or wrapping it in heat wrap and heat reflective tape?

Will do

 

[ElDominio]

I have a Haltech that's randomly overheating, but it's not dead (I have another one I fried, being an idiot, due to be shipped out)

I'm going to try installing a laptop fan onto it to see if it helps, our engine bays get incredibly hot in that area, which is the reason why our stock ECU's case is in the form of a heat sink.

You should take the rubber seal off the hood where it meets the cowl. And the one in front too.
