Without ECU


It's absolutely to the point to have choosen Old VW Super Beetle as my 1/1 scale fun toy. Naturally the emission control was only a canister preventing unnecessary gasoline evaporation, no other devices were equipped, without Engine Control Unit. So the VW 1302 Super Beetle is fully mechanically controled automobile produced 48 years ago. Fuel control is performed by emulsion tube, fuel jet and air bypass adjusting screw as conventional method. But with all these primitive devices, probablly capable to pass the Legal Emission Control Test, CO(Carbon Oxide)> below 0,45% and HC(Hydrocarbon)>1200 ppm.
Anyway newly comming Beetle would be restored by replacing rubber parts, geometric construction correcting and wheel alignment establishment precisely based on service manual datum(on centric value) utilizing special tools and devices. I'm looking forward to see 1302S model on comming Thursday.
