MY TRANSMISSION REPAIR 8hp90

[Mean Cat]

I do believe the tuners could benefit from actually having printed instructions for a guy when he picks up his car. Dos and donts etc.

I agree & exactly how the tune is set up with best mode to use at the track or street.

That’s the thing. No one has any real information. You ask one guy he says this and another guy he says that.
It’s always just like ok I’ll listen to you. And then that becomes what you believe and you tell everyone else that.

plenty of modded cars running on street mode putting 1000’s of miles on car.
All the variables on my car and my trans needs a swap and people say it’s because the trans setting or tune. But no one comments on the power or mods or how I drive. Weather conditions, temps of car. Cooling capabilities or lack of. So many things.
Gets frustrating listening to all the opinions.

The problem is the inconsistencies between tunas. The attitude is: Well this works for me so it "works". Yet, there is little reason to believe, at least that I have seen thus far, as to how they came to that conclusion (other than trial and error). Which is why I stated all you high powered A8 guys need to publicly consolidate your findings, work out a common rationale behind it, and apply it across the board. Yeah, this would upset the tunas - but be realistic about your goals and how you are going to set up the legacy for these cars (because the automagic cars will set the standard) if you want to live and die by the A8. I lived through two decades of BS in the LS world watching the trial and error of fly-by-night tunas and vendors who were really just capitalizing on the ignorance of the customers. If you were smart enough to go to school and get a good job and pay for a Hellcat - you can damn sure learn how to tune your own fucking car. Tunas aren't engineers or scientists <insert your internet credentials here> - they are just the guys who saw and opportunity and took advantage of it. I know this sounds harsh, but it is very much the case.

And then, yes, you have the perpetuation of internet misinformation by the ownership group who choose to pay the Hellcat tax and assume little to no responsibility in comprehending their decisions simply because they paid for a service.

definitely on to something man. You really are. I agree with you.
I would love to tune my own car. I know it can be done. Plenty of knuckleheads out there doing it for money that blow up plenty of parts.
If I’m gonna blow up my parts might as well leave all the excuses and just put it on me.

I’m a busy guy and currently just enjoy driving my car. This is the first car I actually haven’t turned wrenches on. I have a good builder, the part that is the bullshit is the Tuners. It’s such a mess having each guy say the other guy is an idiot and you should listen to me. I hate it.

I think you are on to something about the high horse guys getting the info together.
Maybe we should stay on this topic and try and make something out of it.

 

[hellno]

The high horsepower guys have been there and done that ,I like hearing the success and failure because we all can learn from both

 

[hellno]

Oh and I’m curious what’s determines that your a high horsepower guy lol

I am not sure what your previous post is suggesting - care to clarify?

In the context of this thread: high enough that you consider living with used transmissions stacked up like cord-wood to be acceptable.

So what I'm after is firming up my shifts in drive to match sport and track, whatever those labels actually mean. That way I don't have to worry about it. I haven't intentionally beat on mine in street mode, but the custom setting getting janky on me and me not noticing was enough of a lesson to just make them all match up. I'm gonna head out here in a few and start data logging the trans to see if I can start to build the map of when it's in which modes in the tune. The line pressure is straight forward, what I'm unsure of is if it has to match up with off going clutch pressure, pressure ramp, etc.

Ok, I'll show my ignorance for the sake of education. I follow the charts (2-3 shifts upper and 3-4 shifts lower and the X/Y axis's of rpm and torque) but what are the actual number values representing?

It's line pressure measured in BAR I "think".

Stock tunes is 1 thing but once you have a tcm tune , then I guess then it would be up to how the tuner sets things up either in Track or Sport modes , if that matters ?...& I guess the tcm tune would be at WOT mostly anyway ?

That's correct.

Well in the context I will never be a "high horsepower " guy .

@Speedy you need to start that hellcat list you have the computer skills to do it

Yeah not transmissions too , lol , I already have a spare rear diff & axles taking up space.

I have a couple of questions that I would like some of the more experienced A8 guys to answer:

1 - At generally what ET does the stock stuff begin to give issues consistently?
This is assuming no driver abuse and some small degree of common sense has been used along the way. (insert hellno burning his clutches joke here.. I can't think of a good one right now. lol)

2 - At what point along the ET range as we get quicker would you expect a STOCK production transmission to actually start to fail?

Tuners are not going to “give up” what makes these things tick. It isn’t easy to tune them or make them work butter smooth like its stock unless you have had your hands on many.

The car is still new for the platform, but we are finally at the point where trans tuning is on point and these things will last under big power when set up right.

Plenty of 9 second cars and a few 8 second cars. They are stout it tuned right.

It would be easier to get the caramilk secret then get tuners to give up there secret sauce!

I run 9.6's and put about 10,000 miles per summer on my car . It's almost hard to tell the difference from stock until you put your foot through the oil pan .

we all love them. They never get props at my track. Always have exotics over and they just talk so much crap. lol. Always gap them. But they just won’t give in and admit the car is awesome.
Porche guys are the worst of them all. Followed right behind the mclarens.

Again: Remove the tunas from the equation and empower yourselves, and lift the veil of secrecy - or keep paying neckbeards with fragile egos.

This is how I imagine every person offering remote tuning services:


Regardless, I don't really have a dog in this fight.
