Great input here peeps!
Here’s my contribute regarding Dhalsim Matchup.
If u want to win on this u have to adapt really quick, u have to test how the dhalsim player plays that matchup and very important…STAY COOL! Dont go madly chasing a Dhalsim, it will hurt and u’ll crack, hence, doing mistakes which will cost u the match. Play it cool, u need patience to win this one.
I often start the round with a c.lp, c.mp or l.srk, both of those options beat the fastest of Dhalsim’s limbs: s.lk and c.lp. Then see how he reacts and act accordingly, using c.lp a lot at limbs range always makes the Dhalsim player to think twice before stretching them out. Dont play the fireball war with Dhalsim, ur’s have slower startup and mediocre recovery, letting u open to a s.hp CH, so stop throwing fireballs within Dhalsims s.hp range.
Your objective is to slowly push Dhalsim to the corner, block those fireballs while moving forward, use m.slash to pass through(dont abuse this or u’ll get punished), jump over if its safe to. Another key point is to use Focus really well, srsly it helps alot to pressure dhalsim and making him afraid of using the limbs, Yoga Sniper(j.hp) - which u can focus > dash forward > f.hp to punish it. If u r able to focus crumple an air limb dash forward and l.srk it. Condition the best u can the Dhalsim player, a Dhalsim who cant throw limbs at his will is a Dhalsim falling into defeat.
In this matchup i try to knock the Dhalsim down the minimum possible, even hard knockdowns, because even if u OS on the Dhalsims wake up u prolly wont guess the teleports direction right, which can lead to a wiff punish from the Dhalsim part, but this imo ofc. So i use a lot […] xx l.slash (use OS CrouchTech after the slash to prevent getting thrown), it keeps the Dhalsim on his feet, decreasing a lot his chances to teleport safely, if he does teleport punish with s.hp/focus/srk - i prefer s.hp much more realiable. In the corner he’s preety much done, if u condition him real good in the corner there’s not much he can do, by punishing the teleports he’ll try to mummy/drill out of the corner, punish those attempts. If he manages to get out of the corner, repeat the process till he’s in the corner again.
If u have the life lead SEAT ON IT! Let him come to u, he’ll be forced to take risks and u can manage to punish/stop those attacks from him. When safe - by safe i mean out of s.hp range, if not u’ll be punished of ur way down by s.hp due to the recovery of j.214MK - use j.214MK over the fireballs to build some meter or neutral jump.
If u get caught on the throw > dash forward > ultra1 setup u have two choices(u can also ex.srk but most of the Dhalsims are aware of this due to ryu and company ex.srk escape):
A - ex.slash through it, but this isnt safe, because u can get the slash stuffed by a c.lk/s.mk, but if the Dhalsim player is not experienced with the match up u may catch him off guard leading to big dmg inc, or if u feeling lucky go for b.mp xx h.slash reset(i do use this quite often :P);
B - if u dont have super bar/have hp to take the chip and dont want to expose urself…u have the good ol’ block option. Its important that u get these setups down, so u can block correctly and prevent eating with the ultra dmg.
Setup#1 - c.lp/L.slide > Yoga Sniper(j.hp) - block it low then high;
Setup#2 - Yoga Sniper - block high;
Setup#3 - j.forward.lp - block high.
Of course these arent all the options they have to break ur block, but so far these are the most common, but now u know some setups u may have to face and u can react accordingly to the situation.
Hope i’ve helped someone, i know many of this stuff by playing with a great Dhalsim player since SF4 vanilla days, we lvl’ed up together. I could be so much better if i stoped being a “jack of all trades” a while ago, thank god i have Oni now 
Remember, play this match cool headed, u have the comeback factor, Dhalsim does not. Life lead = sit, let him make the mistakes u want, pressure bit by bit, in the corner dont knock him down and u probalby will have the upper hand in the end. Good luck tho, these out be memorized in a slap of fingers
