Platinum Sport Heat No Start Issues
Hi
I have 4 brand new platinum sport 1000 ecu's here that all refuse to start when the ecu body temp goes over 60 degrees celcius (as measured by a temperature gun).
From all the logging i have done
T per H stays on -1 when the temperature goes over 60.
I have swapped wiring looms, tried the ecu's in different cars, tried different CAS sensors and the only common denominator is the ECU's themselves.
Other than stating the obvious and telling me that the ECU should not be 60 degrees, i want to know why this happens and if it is documented.

Are you sure the ECU is shutting down? Sure you don't have a temp related trigger issue? When the trigger count goes to 0 you're not going to get an injection or ignition pulse. VR sensors are heat sensitive.
I've seen two or three of you mention similar issues but I've never had it happen to myself or any customers. Probably have a couple hundred Haltech ECUs or various series out in the field and have never been approached by a customer saying this is an issue. Not saying it's not happening for you. Just very odd to hear of it.

C.Ludwig, i have had a disucssion with a few workshops who have had the same issue and reported it to haltech only to be told "that no body else has mentioned anything so it's not the ecu", its a very frustrating answer.
When the issue is happening, i have swapped multiple cold Crank angle sensors with no success. The only change that made a difference was a cold ECU.
Please note the ECU itself does not shut down. I simply get T per H on -1.
Please note since putting a massive heat sink on the ECU with a FAN the issue does not happen at all any more. As a test i removed the heatsink and fan for today and issue was present with in an hour. i repeated this process with 2 other brand new ps1000's and the results are consistent. As soon as the body of the ECU tips over 60-64 degrees T per H goes to -1 and no start.

Higgi and i ran into this, he more thoroughly diagnosed the problem added fans to the ecu, and i believe its ok. Higgi's was quite funny as he datalogged the ecu while it did this, and on his the output section shuts down, but the rest of the ecu works, so the data log looks 100% normal, even though the ecu isn't outputting at all.
we were both running 20B's, so we're using more outputs.
Haltech had a couple of software updates that helped, but i think the thing just exceeds the temperature of the drivers, and the drivers shut off.

Can you open the case and replicate the issue by putting stress on ECU? With open case, you might be able to focus on hottest spot / chip on the board......
If we know which chip is bad, we should be able to replace it with another one to fix this issue properly....
