This is my current daily driver at the moment and the aero will be improved. Few new tricks coming and I am hoping to drop the drag around 0,23 levels.


I found a 22,8km long round test route to test the car and figured out how to make my cars test program for future. Previously I already tested with constant IQ program when you floor the gaspedal last 1% travel will give the 80km/h speed required iq for tests, but now I figured. If I build a stopper for normal driving that it wont allow pedal to go like 97% where I have normal max power. Then I can drive normally with the same ecu program and just for testing I take the pedal restrictor off.

Now back to mods
Current situation is abou this with grill block and lowering:https://ecomodder.com/forum/tool-aer...ToStep=40-65-1

I will try 165/65R15 Michelin primacy tires which have A rolling resistance. Will drop consumption at least 0,1 liters.
https://ecomodder.com/forum/tool-aer...ToStep=40-65-1

Then smooth underside on exhaust tunnel, rear fenderskirts, tire deflectors, printed air curtains at the front etc etc.--> cd 0,23

Regarding the block under the gas pedal - Maybe a spring would be better? That way the pedal will stop when it hits the spring, say around 75% allowing economical driving. But in case of emergency, you can still floor it, just with more force.

ecu program is 100% custom so hard stopper is fine and best. otherwise i lose resolution/travel of the pedal...

Just like the so-called "dual-stage" throttle pedal that was fitted to some Volkswagens in Brazil in the '70s?

Currently
0-70% is eco
70-100% is fast driving
Two stage system

New Will be
0-70% is eco
71-98% is fast driving (max 150hp and 1,8 bar boost)
99-100% test program setup (which is limited to about 80km/h speed)
So its 3-stage system.

Would it be able to go WOT at 80km/h?

At 80 km/h speed the 3 cylinder needs about 10mg/stroke injection. In the diesel there is no trottle body so speed in only controlled by injection and boost and other parameters for those.

A lot has happened in this project. Last summer I designed some bodykit parts to get drag coefficient under 0,20.



Now got finally my own 3d printer working and parts are flying out.

Will desing also new door mirrors. Same mirror as in the Audi A8 project, but more rigid assembly. I can also print blocking plates for original mirror place so its easy to swap for inspection the oem mirror.
