Dear uetian04,
With reference to the meter you custom designed, is it available compatible for corolla gli and is it for SALE ? Where to contact? if not any thing similar to this gadget with all these functions, specially temperature monitor + Gear Indication with alert.

Great job ... Mashallah .. This country needs men like you.. Can you make something similar for efi cars .. I think that would be easier for you vs carburetor engine car!
Hatsoff bro its really awesome great work
