Well the Mictrotech is finally in and I'm bloody happy with the results!
So far I'm averaging 13.something litres to 100km around town, and thats with heavy take off's all around the place. Consumption on the freeway is 6L to 100km going with the wind but usuall 7L, travelling at 100km/h.
Still can't beleive it, when I bought the car it was getting 23L to 100km on a good run. Since then I've slowly improved it with a lot of little mods and some major ones, 5spd gearbox replaced the 3spd auto, electric thermo fan, spark plugs and injectors done, new 3.45 ratio lsd diff, cold air intake, all fluids changed and recently the Microtech.
A good friend has tuned it to run pretty smooth now, still some small idle issues when cold and starting issues. These could be linked to the alternator needing a larger pulley or a new unit altogether, starter might be on its way out aswell.
Heres a picture from the night we finished, really have to fibreglass bog and respray the bay when I get the chance! The ecu is hidden within the original vk efi case and the hand controller resides in the glovebox for now.
