Relatively new to the forum and have been in mod mode over the last several month, see sig.. Quetion is should I do the TCU tune?? Been considering this for some time, do I get real gains ect??

If I do do it which one E/C, Speedriven, please chime in with any info....

I have a Eurocharged TCU tune and love it! Raised limiters and quicker shifts. And since I'm running meth, I can run to 6900rpms and still have full power. One of the best mods I've done.

Mine only sees the streets, has not seen a track yet, but I love my TCU, crisper shifts, and a bit more control then the traditional slop box. Not to mention, having no tq limits at the bottom end makes the car even more of a beast.

Dostovel

Hmmmm Maybe I should do this too lol

I just have the EC ECU time, so how much is the TCU tune and is it worth it? (I love EC by the way).

So you're in QC huh? Perfect! Now I have someone to put on my diffuser for me!...

Bramage

Denroll did it locally and likes it. I have not pulled the trigger yet. (I'm not much of a mod guy)

You gotta come out to the drags with us some time! (Qualcom)

Lots 'o fun

Dostovel

The Q is only a 1/8 mile though. Head up to Oceanside for the real deal!

Bramage

??

Dostovel

Qualcomm only runs 1/8th miles, right?

chawkins2001

Tcu here, shifts quicker on sport mode, raised limiter and removed tq limitations. Manually shifting the car is still slow as hell, i can shift at 6000rpms and it engages around 6700rpms.

Bramage

Qualcom is 1/8 mile as is Barrona.


There is no 1/4 mile anywhere in So Cal. Fontana is shut down, Iwindale is shut down

The closest 1/4 is Bakersfield.. Hell, Firebird might be closer


1/8 is fun to go out and race your friends, practice launching and nailing down 60'.. Plus, its easy to go, run and get home in a couple of hours-

Oceanside (Carlsbad) has not had drag racing since 2005 ish

Thanks for all the reply's.. I'm leaning towards doing it as E/C will give me a pretyy decent price.. I pretty much always drive in sport so quickened shifts is always a good thing...

Dane, as soon as it cools down i'll be out there for some runs, never done it, but definitely want to...

Dostovel

Well I'll be damned.... I did not know that. Bummer. I guess you'll just have to roll out to the long empty streets in Irvine by the toll road then.... lol

cij911

Seriously ??? Mine shifts much quicker than that (i'll look at some logs, but it has to be in 1/10ths of a second) and I have not even sent my TCU in yet to be reprogrammed. Maybe your delay is because you are pushing 1000 hp and your car is just too fast .

Mine does the same as chawkins and I don't have any power mods

pearlpower

Good mod, Jerry @ EC will set it up nicely. Anything to add some sportiness to the car is a win. Recommended.

Bramage

chawkins is not saying the shift itself is slow, its the time from hitting the button on the steering wheel until the actual shift begins. No way to log that.

I have been told the TCU tune improves the quickness of the shift itself. I don't think it affects the responsiveness of what has been referred to as the:

Shift Recommendation Buttons

Koru_Kinshi

If you downshift while in S mode, it will still auto shift up at redline, yes?

RedBullJnky

Yes.

DVC

It's good to hear the real scoop, as many users have claimed that it sped up the button response.

Torque limiters....?

If removed, does this in theory mean that we're toying with the life of the transmission? If not, this in itself + the higher rev limit would make it very much worth the purchase.

Bramage

When you make more torque than the limiter is set at, it feels like old school Traction control. It will cut fuel ect.

So removing the torque limiter will allow you to use more of the available torque

Will this decrease the longevity of the transmission?... maybe, but not in itself. The modifications taking the drive train well beyond its design (HP/TRQ) comes with risk, and most who mod accept those risks

Celicasaur

I see...but wouldn't that just make the car harder to drive fast because if you're a girl like me and you like the TRC coming on to stop you spinning, it would give more torque before the system stops the power?

Ahem, if only....if only, a 2.8+ diff conversion didn't cost an arm and a leg for this car....

Denroll

Check out the torque dip in the darker line here. First run was aggressive with throttle and hitting the tq limiter and the second run was a gentle throttle roll-on without hitting it. I have since received the updated tcu reflash with the higher limits, but I have yet to hit the dyno again.
