How much did that cost you? And do they do one to specifically suit an R34 GTT?
I like the look of their design which is why I like the ebay one I posted up above.
Has anyone ever tried one of these cheap chinese (or thai?!) items for an R34?

I've been tempted to give one a go but its only going to delay me finishing my build even more, and I would need to change intercooler and a few other bits
If you did that you would have to be extremely careful not to ever come onto boost if you had really ramped up the boost / timing with the WM mixture injecting. Otherwise good bye motor very very quickly! I wouldn't feel comfortable driving it around like that for any period of time!
Just get a float sensor for the tank and a warning light, and carry some extra WM with you. Or invest in a failsafe device.
I recently bought the AEM failsafe device which looks very good. I will use it to trigger a second map in the ECU.
Thats a good way to describe it. The semi regularity (but still rapid) nature of pinging is a good way to differentiate it from from other more regular vibration kind of noises. Still its pretty quiet so it still can be hard to hear over all the other engine / exhaust noises.
As others have said, if it is pinging and everything is pretty much stock, it's most likely your base timing is out and you need to adjust your CAS.
If I remember correctly (I recently installed the same cams), Tomei says the correct clearance is 0.4mm (intake and exhaust). Seemed quite large, but who was I to argue with the manufacturer So thats what I set mine to. I also installed stronger valve springs.
Yes I should complain given the cost, but to be honest I'm sick of dealing with them and waiting to actually install it, so I'm just going to leave it. It shouldn't have any effect on it balance or function, or at least I hope!
