ss4000 to loose!!!!
Transmission tuning doesn't effect 60'??? It does if the converter flashes to 4400rpms and the transmission shifts early. I'm not talking about just the tune being off. I'm talking about what he SHOULD have been 60'ing with either of those and something isn't adding up.
Here is the Camaro cutting 1.52 60' times and 11.6s in the 1/4 with stock internals. I think his whole setup is QA1s all around, adjustable everything (TQ arm, LCAs, Panhard) BMR kmember with upper and lower CAs. Performabuilt LVL2. FAST 90/90. Also before you say "That's not an 11.6 pass" read the comments. He went 11.6s the same day with tuning.

And I'm not doubting you in anyway that the car did what you say, but that video is far from a 1.52 or an 11.6. Either way you should be very proud of your cousin's customer's car.
Ok I didn't even consider the possibility of the trans being commanded to shift at 4400 rpm and 1mph. The reason being is that it's unlikely by any tuner to be setup anything like that. Plus he probably would have mentioned that it shifted way to early.

I didn't say it was shifting at 4400 and 1mph but it might be shifting just before the 60' mark with stock shift points still in the tune. I'm not "proud" of anything just pointing out a car with the EXACT SAME CONVERTER he is using. I'd say that's more than relavent. I'll leave this to you to figure out since I am obviously on the wrong track...

Did it ever occur to you that not every car is that same. This guy doesn't say that he has drag wheels (like your cousin's customer's car) or might not have any weight reduction (like your cousin's customer's car), etc,...
Still, none of that is the point. If his SS3600 cut 1.5 60's and the SS4000 cut 1.4 60's it still doesn't add up in the 1/4 ETs. I do have an idea what it might be because my buddy had a similar problem, but I'm not gonna post anything negative on Yank's part because Dave did some what rectify the problem.
With the mph he's trapping in the 1/4 it's doubtful that he's shifting before the 60' but even that wouldn't be worth 2 tenths since you obviously think that everyone with a SS4000 should cut 1.52 60's since your cousin's customer's car does.

I don't even care about the 60'. Yeah it sucks. The car doesn't work that well in the 60'. That's not the problem he's worried about. It 60's better but still runs worse in the 1/4.
It's not 2 different converters it's the same converter that has been restalled.

Well I have a brand new SS4000 on the way now...if it doesn't do better than that it's coming out and I'll drop in a Circle D 5C. I remember the other thread that guy had about this and I could have sworn he didn't have any tuning done when he installed the converter. Mine didn't shift right until I tuned it. I had to speed up the shift times because it rolled into gear like it had tons of tq management and was slow shifting. The converter confused the ECM and we had to command different shift rpms to get it to shift at the rpm we wanted. I think it was like a 200-300rpm difference between stock and with the converter in.

What converter do you have now that you had to change the calibration?
TQ management is more about pulling timing during the shifts. 99% of the time the only thing adding a converter will change is that it shifts too late because it turns up to fast. That and the TCC lockup speed needs to be raised.

I have a cam only Ls1 and my buddy has a H/C Ls1 that we built. We both have the ss4000. We ordered them both at the same time. I will say mine feels alot looser than his. Its a big differnce. It all comes down to the owners idea of being driveable and streetable. I feel that mine is too loose because this is my 1st small cube motor so i am not use to this high of a converter. I work at a transmission shop so i deal with them every day. There are so many variables that go into making a converter, like clearinces,tollernces. If there is 1 converter that the front cover is say (ex)3inches high and the other 1 of the same brand and model is .500 taller its going 2 feel looser. Same with not 2 pepole build them the same even in the same shop with the same material. Thats why when you buy a (stall converter) they state the stall speeds are approxment. There is no way they can set a stall rating dead nuts rite on.
The op pepole are just wondering why you are concerned about your mph when your 60' is so shitty.

I'm not worried about 60' because I no suspension work ill deal wit that later. Dave told me that the 4000 will drive bout the same as the 3600 and it does not. I've had 4 ls1 car wit stalls none felt this loose. And the car is slower!!!!!

Agreed. You can put whatever converter you want in the car and it aint gonna fix the problem, I promise. It's not the converter.
I think its something other than converter. I have an fti 3800 and built 4l60e I have bone stock suspension and cut 1.61 60'. Plus your MPH and times are slow for a forged bottom end car with that size can I have a tsp 228r with milled 241s. I have not done a full 1/4 yet since the closest track is an 1/8 but I run 7.4 7.5 at 92 MPH.
