I found this on the on the Vitesse site, but got an e-mail from John saying they don't sell it.

Does anyone know about this? Tuning without knowing the actual ignition timing sounds a little scary. Are there any other tools like this around.
I may be paranoid but I just installed a highly recommended chip in a VW 20V turbo and found out that the timing is about 15 degrees too far advanced. While this may be caused by differences in the MAF or TPS at least I know about it and won't push the car until its remapped.
