one thing I have noticed about my car, it doesnt like to shift while the wheels are spinning. I havent really sat down to think about that one... but I have observed that if I am in first gear banging the rev limiter from tire spin, its not going to let me into second (nasty grind) unless I let off for a moment. I assume the tires and drivetrain need to decelerate down for everything to be happy and allow the shift, just havent really thought about it yet.

I have the same issue. I try to get out of first as fast as I can with reasonable throttle input, then mash *within reason* the right pedal from 2nd, on.

Never thought of that before but you guys are right. Banging second gear can be difficult, it would be so awesome to have a torque limit per gear so you could contain it down low. Every other gear works flawlessly, I can no lift shift all the way down the track with no issues. Its just that 1-2 which kills the ET.

I've had this EXACT issue both on the drag strip, as well as the road course. 2 gears inparticular stick out to me, 3rd and 5th. I remember being on the straight stretch 4 laps in a row, and the car literally would NOT LET ME PUT IT INTO 5TH?? I was like, wtf, there is NO WAY that I simply cannot find the gear??? Then I realized when I lifted completely off the accelerator early and shifted early with no redline, it allowed it to go in.

This past weekend, I had the same issue going into 3rd, causing me to shift early and actually held the clutch in early, delayed, and then shifted just to make sure I could get a run in without the car refusing me to get it into 3rd.

THEN, of course the fuel starvation. Have had this on the road course, saying I had over a half tank, yet completely shut the car off in the middle of accelerating on the straight. Wouldn't start back up, disconnected the battery hoping it wasn't something electrical. Sure enough, once I reconnected, the fuel meters/lights were completely empty. Have also ran out of fuel/cut off during auto-x events and exit ramps on the way to events.

uggggh, the struggles of the 370, yet I still love this damn thing and can't get enough of ittttt!!!
