Latest update on this project is trying the Fab9 tune. It is smoother with light throttle. Peak power seems down a bit as they are working on getting full timing advance but very light throttle is smoother than EB tunes. Did a longer freeway drive and cruise control (which was an issue for EB tunes) and that too is quite smooth.

New adventure for wife's RF, took it to autocross today, won SCCA SSM Class!

Found the Achillies Heal, it's needs a limited slip for autocross. Amazingly, lack of it has not been an issue in street driving and even aggressive canyon driving. But Autocross is TIGHT, and our SE lot at the stadium is extra tight and I lost about 2 seconds with wheel spin. Tip toed to the win by avoiding brake use and carrying speed everywhere but ability to lay power was certainly compromised and will soon add a limited slip.

Purpose of taking the RF to Autocross today was to test RF version of our popular RoadsterSport springs. Springs did great.

SCCA Autocross Day testing RF RS springs, 300 front/200 rear. Last event without limited slip, this event with factory limited slip. There were moments I regretted not doing an OSGIKEN in this car but given that this is my wife's daily driver and not built for competition the stock limited slip we added is effective enough for the mission of this car. Last event I had to tip toe around the course, frustration was constant. This time I was able to lay power out of tight turns much better. I still spun the tires, but this time it was both tires instead of just the inside wheel. Fun and faster and I could throttle rotate more effectively as needed. Balance of the springs continues to feel great in the RF, had the KONI shocks full stiff front. Started full stiff rear for KONI but oversteer was a bit much with the 200 hp supercharger and current sway bar settings (soft front, middle rear) so I backed it down half a turn and went faster, backed it another half a turn and went faster again with more effective rear hook up. Could have also got down and changed rear sway to soft to better match the front but didn't bring the tools and towel to get that done neatly at the event.
