4th gear issue

[ashley.longley]

Has anyone been dealing with 4th gear issue's using H pattern shfter with e30 bimmers and Arbath, issue I am having it's all sweet on all other gears then it's like I have hit the handbrake as soon as I touch 4th, but the old open wheeler car no issue.

No issues with 4th gear, but the downshifts feel awful with my G27 h-patter. They feel like the clutch is damaged-I often have to use the clutch's maximum and feather the throttle and brake just to get a downshift, and even then that only works about 60% of the time.

Probably a configuration issue on my end.

Before you get the l2p comments, ill offer some advice, what your experiencing is a lack of proper heel and toe, you need to blip the throttle whilst changing and comming off the clutch on a downshift. Ill find you a video to explain it better

Its easy for me to rattle off an explination, a video that shows you how to is so much better

Thanks! I've never owned a manual IRL before, I guess that shows my inexperience.

we're talking about upshifts not downshifts and i have the same problem
upshifting to 4tyh, i or we lose power in that gear

No issue here personally for upshifts or downshifts, are you able to create a video of your issue, or atleast explain it in more detail?


About instability on downshifts. Heel Toe (and double de clutching) only really "needs" to be done in non syncro gearboxes that you would find most commonly in racing cars. Most road cars (all modern road cars) have syncromesh boxes where the gears are syncronized to the correct speed of the next gear, this is why you can so easily change gears in a manual road car, you don't grind gears and you don't need any special technique.

Though when changing down gears faster than normal (common while racing) you need to heel toe to raise the engine speed to that of the next gear in order for there to be a smooth transition. If you don't then what happens is that the gear will hit the engine at speed and you will get an excessive ammount of engine braking, sometimes enough to cause the wheels to lock up and the car will feel very nervous and unsettled during downshifting/braking zones.

That depends on the car/driver though, some people don't like to rely heavily on engine braking and will slow the car on the brakes and then block change gear when they are closer to the appropriate speed. that really depends on the car. In the old days the brakes were really bad so engine braking was needed. On the other end, if you look at modern F1 they try to avoid engine braking firstly because it wastes fuel and secondly because they harvest the braking energy into the energy recovery systems.

was this issue ever pinpointed??? I've started to have this problem, but can find no solutions in any forum...

With any (manual) car, they accelerate normaly. Get to 4th gear though, and it will either bog down and refuse to accelerate further, or whip around like the e-brake was pulled. And no, the ebrake is not mapped to 4th gear.

I will try it later tonight. With problems while driving people need to provide videos.

I just did a lap in the E30 M3, E30 M3 Group A, and the Fiat Abarth on Spa...I had no problem going in to fourth and didn't feel any bogging. I will try out other cars later.

I'm using a clubsport shifter.
