Uprev + 6MT: Can TC be manipulated?
 
Hey all, I'm looking into adding significant power (SC kit) and am seriously concerned with how invasive the stock traction control is. Even mostly stock, its easy enough to accidentally trigger TC activation and experience a 3+ second loss of power. I'm sure you're all familiar.

To the point, I've got uprev now and I'm curious if there is a way to manipulate how invasive the TC is through my tune. I know its possible through the ECU since ECUTEK offers variable TC. However, I've struggled to find anything with regards to uprev and TC...even on the forum. Might any of the "Torque Management" tables somehow modify the calculations used for TC? Has someone tried this before and I missed the post? Has everyone given up on variable TC with uprev?? :/

I did find this...but I believe roplusbee was working with a 7AT:

So turning ETC off killed pretty much everything. Dave was able to adjust the torque table and that made it so that VDC was less invasive. Uprev Tuning Info

With Uprev, I don't think so. I just turn my TC off. I never use it.

:iagree:

Even with VDC off the ABLS feature still applies brakes when wheel slip is detected. Gotta wire in a switch to turn off the yaw sensor if you want all the TC nannies to leave you alone.

With VDC off and Ecutek, The only thing still working is the stability control via yaw sensor. Since I have a OS Giken 1.5way diff it rarely cuts on. From what I remember if you are doing a burnout, you can use Ecuteck to disable that part. On a stock car the only way to disable all of it is to put a switch on the Yaw sensor to disable it.

Get Ecu tek and a good tuner, problem solved

Ha ha, I guess with almost double the stock WHP I’m more worried about breaking loose when I really don’t want to. Perhaps thinking that TC would make that condition more safe is a false hope?

I get that a lot of people want it off. In my build I’m aiming for a vehicle with tremendous capability but also it’s ability to control that. I have another high power build but notably it’s an AWD Subaru so I have double the footprint to put down that power. Day to day I want to use as much of its capabilities as I can without losing overall control. Aka, I recognize that building a high power platform makes it much more challenging for a driver to know the limit at any given point in time - especially at higher speeds when response times must be faster in order to maintain control.

Then you picked the wrong platform lol. Boosted Z's are a handful even for experienced drivers :driving:

You're going to have to compromise somewhere. Find that sweet spot that works for you. Ecutek features will probably be the most help to you. It will likely take some testing and patience for you to get there. There is no right answer here.

Also, controlling the car shouldn't be an issue when driving responsibly on public roads. If TC is intruding other than when giving it a bit too much off the line, take it to the track. Seat time and throttle input practice is all you should need anyway.

Yes, that is a false hope. Get the correct supporting mods to go with whatever you are building. Then, learn how to drive it. In a high hp car you always have to be ready for the unexpected. They will surprise you when you least expect it. 700whp is not too bad. Go above that and it goes up exponentially.

That does not save you from yourself.

LOL, yeah we both have been there, done that. The luck bucket was just shy of the experience bucket. I've been in a ditch a few times.
Lost a little luck and gained some experience of what not to do.

Ha ha ha, ok I get your point. Thanks guys, I appreciate the thoughts and quick responses! I've been hearing of boosted Zs breaking loose in 4th gear lol...but I get it, the cheesy great power great responsibility ;)

Oh and in terms of public roads - I fully agree with you. I do currently take the Z to the track...as its basically born to be there...and plan to return with the HP increase. That's not to say that it's uncontrollable or won't be fun but just that I'll have to be exponentially more careful than now - where I basically can't get too crazy with the accel pedal.

Yes, they will step out in 4th in the triple digits but we are talking about 900whp worth. They will also step out passing someone going over the white painted lines on the road. All kinds of, I am going to kill you, moments can happen.

With just over 500 whp/440wtq, the Z is still pretty manageable. I'm not saying it won't try and kill you, but as long as you're not unreasonable with your pedal inputs, it's still pretty predictable.

Spoolers world is totally different than mine though.

Yeah, I went off the deep end. I was real happy at 718whp. Now I have pushed it up to where it is a handful. My level of crazy is a tad higher than most. :rofl2:
