I dunno. Your brakes and rotors look like they weight 100lbs each lol. Plus you still gotta upgrade the wheels. But for sure let me know if your interested in hitting up the track. I plan to go next week after the e85 tune

 

Lol they aren't that bad though as for the wheels those are a tad heavy. I will be soon I will let you know.

 

yup if you got a high 12second car with a 1.850 60ft and a 8.185 1/8 i ran a 12.7@ 108mph

 

Just to let everyone know cobb will put the dynos up once the e85 tune has been completed. That will be this thursday! Ill post them in the same sheet so you can compare.

 

E85 TUNE DONE! Update on first post!

 

I went to the track today with the E85 tune. Went into LIMP MODE every single launch while the monitor displayed the Transmission Overheat sign. I shifted at 5-6k RPM's each time, but the car would still stay 1st gear and run all the way up to 9k RPM's each time. The torque just jumps so fast now it never shifts to 2nd gear on a launch. I thought about trying to launch at and shift at 4k RPM's to see if it would catch and shift to 2nd gear at around 6k RPM's but I got kicked off the track from holding up the line multiple times. I even tried launching at 3k RPM's in sport/auto and still went into Transmission Overheat/LIMP MODE

Anyone on E85 have this issue with the SST Tranny???? On 93 Octane it shifted perfectly and didn't climb the rpm's so fast and hard. I tried some launches on the pavement off the drag strip and the launches were solid, but on the strip the tranny just pooped on me.

 

You are getting clutch slip. 9k is not good for your motor, I would imagine it's just hitting your rev limiter and you think it's 9k.

You might also be hitting 30psi+ which disengages the clutches unless you are tuned properly for it.

There is a "hidden" limiter in 1st with the RA/10 that not many people discover. Congrats you found it.

Sounds like you need to up the clutch pressure and do some 'creative' tuning for 1st and 2nd.

Been there, done that. All that torque is just a number on a paper when you can't actually use it.

 

i wanna say that you got too much wtrq and your clutch just cant handle it try a better tranny cooler and better tranny fluid it should help a little bit

 

Can I have more info on this? I'm interested in fixing this problem. I was at a "ghetto" track which is american muscle biased, so getting laughed at wasn't exactly why I went to the track

@baggelis
I'll take your advise on the transcooler and tranny fluid as well. Is the SSP tranny fluid that much better than the stock tranny fluid? Lots of tuners seems to not think so.

 

One of the strategies is to use gear based boost to your advantage in 1st and 2nd. However the table is defined incorrectly (and has been for years) in AccessPort. So you are out of luck on that until they fix it.

There are also a couple of other things as well, which are also currently not in AP but I heard a rumor they might be in the next rev, whenever that is.

 

Like Bryan is hinting at, you need an Open Source tune. This will allow your tuner access to the Gear Based Cross-Over for Boost/WGDC/etc. Should allow them to limit the boost to start with (so the clutches will engage and send power to the wheels), and then bring it on stronger in 3-6 (or wherever they choose to set the cross-over point).
But then again of course Cobb will want you to use their product....
Nice numbers tho

 

I'm not really hinting he needs an EcuFlash tune. More just informing him of some items he should look at to assist in fine tuning what he has.

Currently, the AP does not have these features, or they are not working correctly. I do know they are working on adding / fixing some of those features.

It really depends on the end users current and future needs / wants on which platform to use.

 

 

Well this is an easy issue to fix, most MR/Ralliarts have the 1st gear limited 18-20psi so that when you brake boost launch it won't shoot at 30+ psi as Razorlab stated. Cobb is going to send me some instructions and programs for the AP to log how my car drives. As you may have read is Razorlabs reports and loggings (I don't have the link on hand) the limiters of the SST tranny is different in the RA and MR.

 

Man on man...

I called up SSP to ask more details on what they thought about the clutch matter. It seems like running anything over my current Torque would destroy my motor because the 4b11t is no where near as powerful has what the SST can do (explained below). He also stated that it would seem more accurate for the wtq to be at about 360-370wtq (guess cobb does have a higher reading Mustang ). He said that if I was truly at 400wtq, then I would have some serious issues coming my way from what the stock clutches AND motor can actually handle.

Then, he told me something that blew my mind. I always see everyone getting 600hp clutch packs, but he said if this is your daily driver and you want to get the MOST out of your clutch packs, go for the 500hp. The 600hp pack has a low life expectancy and is primarily for "blow yo **** up" type mods, meaning motor upgrade and bigger than FP Black type turbos. The 600hp pack does hold the claps harder, but the 500hp can be modded to hold just as good (not on par, but enough to maintain everything property). Yes this does mean 500hp will be more than enough for anything you plan to do with your car. He said the 500hp pack can hold up to about 560ish whp, but no more than 400wtq is recommended. He said that the issue with the SST tranny is the internals go bad before the clutches do, and they are in the prototype phase of creating more reinforced ones. They should be out later this year or next year.

Now keep in mind, I didn't say the 600hp pack was garbage, its just that the 500hp is more practical if this is your daily driver or you aren't running heavy duty expensive mods. Let alone the fact the tranny can be modded to help grab the clutches slightly better with just the 500hp is more than enough for me.

Also, 360wtq range (low reading mustang) is ALL the 4b11t can handle while equiped with the SST tranny. The dual clutch pushes so much power that the motor sometimes has issues keeping up at high torque levels. Anything over 360wtq (low mustang) and the motor's rods start to get wear and tear fast. Once you start to hit over 360wtq, its time to start upgrading the motor, or risk building a whole new one. He even stated that with the SST tranny, the difference between 400wtq and 430 wtq, although its such as small gap, is a whole new world of torque.

Oh, and ofcourse, a transcooler is mandatory for 350wtq+ if you plan to road course or drag race. If you are at one of these events, he recommended if your running a small batter kit to start your car up occasionally to make sure your battery doesn't die because a transcooler takes up quite a bit of power. SSP even has the option to give you a switch that would allow you to turn the transcooler on or off so it can be used only when needed. So during your DD, you can keep it off, but at the track, turn it on, and keep it on.

Let me know what you guys think. It looks to me if you stay at an RA turbo, your fine, but once you start to upgrade this car past it, you're looking at some serious cash to be sending.
