I was wondering if anyone has the Greddy hooked up as a turbo timer, and as well does the lapping function work. I just read somewhere that it's a Japan only thing? Who knows, but I only want to buy the thing if the lapping function works.

Thanks,

David

 

i've got one but have no clue about the lapping function, so i'm pretty much worthless. sorry. check online though greddy has the manual for it on their site.
