Paddle shifting feels more responsive than in D and S?
 
Does anyone know why my car feels a lot more responsive when I'm shifting behind the wheel than when it is in D and S? It's tuned just to throw that out there. & I'm sure there's a difference in response, I've been driving my car for 4 years and I can tell

Thanks for your input

There should be no difference... the tune affects D gears 1 thru 6... and S gears 1 thru 6 independently but not tap shift. Your tune is probably set up a bit firmer in S so what you're experiencing is the difference between D and tap shift mode, plus you are able to hold your shift to higher RPMs using tap shift.

I was thinking that there shouldnt be a difference but the car is much more jerky in tap shift than in S :noidea:

Then it's the shift at higher RPM than normal. It's a good thing and you have a great tuner.. Enjoy..:smoking:

Is there anyway that I could find out at what rpm to shift at???

If you have a dyno sheet that'll tell ya :thumbsup:

Using paddles it's all up to you. Just run your car in Sport mode without paddles. Paddle shifting is totally worthless for anything performance wise. They are only for fun.

You'll know when to shift when it starts banging out. ;)

Using the paddles, when I have the rpms up around 4ish it def jerks when u play with the gas. can't do that in D or S, when u let off gas alil bit it shifts up and drops rpms stopping the jerkiness.

The tune effects tap shift as well.

There are pressure, shift timing, and converter lockup settings for drive, sport and tap mode.

i dont know how you drive car, where you drive it, or anything about your car.

i disagree. having more control of car is a performance increase in my opinion.
ya 1/4 mile its prob best to let car shift anything else i would say a human brain

I stand corrected... I had never seen tables associated w/ manual mode.

Yes, I'm talking about both drag and road track. I guess if you're holding rpms in the power band around town that would be considered performance, but if I'm going WOT I'm certainly not going to rely on tap shift.

I was using the paddle shifters for a few roll races, came in handy. If I used the paddle shifters it's usually to hold out a gear on the highway so I can scare people.

having the car at the right and predictable spot in the powerband coming out of turns is pretty important in road courses. using some downshifts for braking also can be considered performance orientated.

with all that said, i am killing my stock ss trans. will have the one out of zl1 and ctsv with customized gearing before summers out.

I think I may have been misunderstood a little. When I am tap shifting I feel more pull and jerk out of first gear then when I am in D and S. Its like if the gas peddle became 2x as sensitive!

infernostripes! 07-01-2013 12:46 AM

I know you all probably think I am crazy :crazy: lol But I promise its a different animal in first gear when I am tap shifting

Miles 45thCSS 07-01-2013 03:09 AM

Thats because in the l99 the 1st gear is really aggressive. A little higher than 4.00. When you put it in sport mode it starts off the car in 2nd.

this and also when the trans is shifting itself it will upshift into higher gears at a steady cruise/light acceleration.
which means it has to downshift if you floor it and that slows the response time compared to tapshifting and manually holding a lower gear and keeping the rpm higher.

that 1st gear (and even 2nd) is tricky to tapshift correctly without hitting the rev limiter due to the relative slowness of the shift.
if you wait to tapshift until a few hundred under the redline, the rpm increase will beat the shift into second and you hit the rev limiter.

Could likely be from different torque converter settings between tap and the other modes. Does it seem to just rev more freely?

infernostripes! 07-01-2013 11:12 AM

No it's not that it's revving more freely. Let me see if I can explain this better. If I'm at a standstill in the tap shift mood and I press the acceleration but pull of quickly the damn car bucks like horse. If I were to press the gas and let go quickly in S or D the car doesn't really buck. Like the only way I can drive in T is if I fully commit to having the peddle pressed all the way down. I hope that helps

its because as I mentioned, in S or D the trans upshifts as soon as you reduce throttle and no engine braking occurs.
when you hold first with tapshift and let off you get massive engine braking because its such a low gear.
back in the day pickups that had a 4 speed stick manual with granny first gear, you could get them to pop wheelies in first just by getting on and off the throttle several times to rock the truck.

you just have to be smoother with the throttle or upshift a gear before letting off the gas.

just thought of something else.
I bet that GM designed this trans so the PCM can turn on engine braking in all gears when in tapshift mode.
the older 4L60E had it in 1 and 2 only in manual shifting with the stock design, mines modified to have it in all three lower gears which is great when manually shifting.

Ohh ok. Thanks for expanding my knowledge Mr. Pogo!
