G8x Steering Wheel Installed

[DarkZupra]

@Eastwood might be on to something here. doing this can cause serious injury. on a low impact accident a single stage airbag might deploy with too much force or worse not deploy at all. so now NEW question! can someone retro fit dual stage airbag onto the g80 wheel so it'll work on our cars

You CAN and SHOULD get a dual stage airbag with a g80 conversion wheel. I have one. The problem is people cheap out and end up with a wheel company that doesnt know the difference or doesnt care. Thats why i always use Phillip (Leather Werks Auto) because they stand behind thier supplier and get you things properly.

The seller said that they sent me the wrong airbag since in some regions Supra does come with single stage airbags from factory.. so I would assume that they do have the dual stage airbags. Just need to specify that when ordering.

They should 100% send you the right airbag.

I would eventually order the right one. I pretty much got a 50% refund for this from ModAura.

Single stage airbag, no secondary at the top (near your thumb in this pic)

BTW this explanation is misleading. SIngle stage means no control over the speed of extend of airbag explosion. Dual stage means there is a small motor/sensor that controls how far the airbag should go when deployed. Both airbag was used in BMWs, only newer and higher-end models have dual stage. European car with stricter safety regulation uses single stage to prevent malfunctioning of dual stage sensor/motors.

Here is a quote from bimmerworld.

Single stage airbags go off at a present speed and power. Dual stage airbags go off at different presets according to the load sensor on the front seat, so for a really light driver or passenger the airbag will inflate at a slightly slower force so as NOT to injure a smaller occupant.

Both will employ the sensor in the seat so that if no occupant in front passenger seat, the airbag will not inflate.

Here is a thread talking about where single/dual stage is used. "BMW’s in the US use dual stage airbags, Europe uses single stage."

Go through Leather Werks Auto (use my code mattmk5 for 10% off) and they will send you the proper airbag so you dont have to worry about that.

I second this, they have the dual stage proper airbags and they don’t throw a code.

When he said near your thumbs, he was talking about the 2nd sensor that makes it dual stage. Here’s a picture of it….

You are right that it is a single stage airbag, and OEM uses dual stage. I didn't do much research before buying so I think part of the responsibility was on me. The seller is a Chinese factory and they ship worldwide, and I believe they told me some parts of the world's Supra uses single stage.

The issue was that there was a small gadget that measures/controls how far the airbag should be released missing from the aftermarket steering wheel. We faked it using a 2.2 ohm resistor so that the control unit thinks that gadget is there.

The airbag comes from TRW, which is a genuine BMW parts manufacturer. The electric pulse that releases the airbag should only come from the two wiring directly attached on airbag, not other gadget. So I am fairly confident.

Attached is the aftermarket airbag. I think even ZF (original manufacturer of Supra airbags) uses TRW.

What did the dual stage airbag looked like when you got it replaced?
