I dont understand the reasoning why people note that the ATTS unit will disable itself above 250whp?

why is this being based off horsepower. ATTS is "active torque transfer system" which would hint that its the torque output that would disable the unit once it couldnt handle transferring a certain amount of lbs.

I just wanted to know where this mystery 250whp came from?

 

polly some noob that didn't search

 

lol does make alot of sence "torque" glad i got a 4th gen

 

I completely understand what you're saying, but I never thought of it just actually disabling itself, but that it would just not be able to function "correctly" or function with a greater level of torque..

But who knows who actually first started saying that..

 

i wish i knew what an ATTS unit looked like

I remember a really good writeup on this months ago. Check out this thread...https://honda-tech.com/zerothread?id=1858351

This is probably the most detailed thread you're going to find on the ATTS unit with plenty of pictures. Very informative and well worth the read. to Revi for the writeup and pics.

 

 

it would be interesting to find out the max threshold of the unit.

 

Wow! Some crazy *** planetary gears .

I bet the only part that would "burn up" is the clutch discs and plates. Maybe run an aftermarket bigger cooler instead of the oem one in the radiator.
Cyrotreat( i think that's what it's called) all the gears.

Just like an automatic transmission, keep it cool and clean(regular flushes). Heat and dirt= death to an automatic.

 

I always heard ATTS preludes hated mods. That they just can't handle lots of power. Maybe I am wrong.

That's why I bought a base and plan to rebuild the tranny and add LSD.

 

Does the ATTS system have its own computer? Someone mentioned a while back you would need to tune a system that made 250 horse, and that would disable ATTS anyways.

 

Yes it would 98vtec.

I'm kinda lost on what Steveo is suggesting.. ATTS /= not Automatic

The ATTS has it's own computer or it's built into the stock ECU, I can't remember at the moment. But yes, that is one problem for not being able to run higher HP and TQ.

 

seperate unit.

Also what are the odds you are going to be making serious power without a good ems. Greddy emanage and vafc, im not sure but how many ppl making big power do you see with those.

what are you talking about?

 

most ppl that are going to be making more than 250 whp arent using emanage or vafc. Therefore you disable the atts anyway with all the other ems units.

So to me it makes sense that this would probably be another myth most likely however im sure it does have its limits but i think 250whp was just a number that seemed like it would work to ppl.

 

I doubt it's an exact 250 wheel horsepower number. I would think, well ATTS is made up of multiple clutches. They obviously weren't designed with the thinking that people would mod the car and such they left them weak. The more power the faster they would burn out I assume. Who was the dude on here a while back that was talking about getting custom clutches made to fit the ATTS?

its not about horsepower

 

i understand that but thats not the point i was trying to make. Im just trying to say that 250whp was probly a number that ppl seemed to accept as true and therefore became true in our eyes. I understand that hp is nothing but Torque x rpm/ 5250, just a number really.

 

It does seem to be an often thrown around but never actually confirmed #.

 

Alright damnit which one of you had that avatar first?

 

I understood that the little clutches would start to slip around 250hp...

 

clutches hold torque tho

 

Well, yeah, but at a certain point they will slip right?

 

i would imagine so...just like a stock clutch.....and i would like to know approx what the value might be so we can start correcting people on it.

 

SEND IT TO MYTHBUSTERS!!!!!
