I'm curious if there's a way to program the BCM to ignore the turn signal hyperflash issue after installing LEDs (eliminating the need for resistors all together) either using tuner software or a Tech II tool.

I highly doubt it as the speed of your blinker isnt controlled by your ECM or any other computer. Its the resistance of the electrical pulses being sent to your blinkers that control that and by adding LED's you've eliminated that.

Clever question though. I'm glad radioflyer is still trying to trying to lead a path for us to finally have LEDs without the hyper flash. I wish the Vette used a flash module that can simply be switched to an LED version.

What makes this venture difficult is there isn't a solution where all we would do the difficult engineering on our end to build a plug-and-play solution for the customer. Everything revolves around either the computer (which the customer would need reprogrammed if it is even possible) or install a fancy load resistor somewhere upstream of the turn signals in a place with good airflow and away from heat-sensitive components. This solution still puts a fair amount of work in the hands of the customer and typically doesn't look as nice as they would like.

By hyperflash do you mean the turn signals are blinking crazy fast ???
If so yes that is common with LED bulbs---The fix has always been in the past to install an "electronic " flasher unit instead of the analog flasher that is stock
LED's use a very small amount of watts/amps---so the analog flasher will not work with such low draw--however an electronic flasher will operate will an extremely low draw
I always get mine at our local speed shop or on E-Bay

Yes, that is the issue, but with the C6, there is no stand-alone flasher to replace on the C6. The turn signals are controlled by the BCM.

Most of the common tuners, only control through ecm, and the tcm. The only time I have ever seen the bcm tuned is on a relflash from a tech 2. And that is done using a gm factory program.

Are you saying with certainty that hyper flash can be tuned out at the BCM after all or just that generally, the BCM can only be modified by a Tech 2?
