supra_surj Posted April 9, 2008 Share Posted April 9, 2008 I tried it, loved it. Went back to sequential but now am changing back to TTC with fuelling mods. Quote Link to comment Share on other sites More sharing options...
madmunky Posted April 9, 2008 Share Posted April 9, 2008 I tried it it was ok, but back sequential now, didnt really see the point unless you want to save fuel by driving without the turbo coming online. Quote Link to comment Share on other sites More sharing options...

When you say fuelling mods, what do you mean? AFC etc? I already have a walbro pump fitted. Why did you love it or hate it guys? Also... where's the link on how to do it?

Jim_1979 Posted April 9, 2008 Author Share Posted April 9, 2008 What are your thoughts on it? I've got some weird exhaust valve sticky issue thing going on. It'll be alot cheaper and less hassle to switch to TTC rather than either taking my car to a garage or ripping the turbo system out myself.

Ive always been stuck on what i would need. Just bought an emanage to adjust fuelling and timing. Need to get it fitting and mapped at some point.

Also... where's the link on how to do it? Yea and AFC should do the job. Not 100% sure on exactly what is needed so have PM a couple of members who are running TTC for help. Mines full bpu as well. Saving on petrol is the main thing i like but the nice power delivery just like a single. Quote Link to comment Share on other sites More sharing options...

supra_surj Posted April 9, 2008 Share Posted April 9, 2008 You will need something to adjust the air fuel mixture. type in TTC in the search loads of threads will pop up with whats needed. I just been reading them. Quote Link to comment Share on other sites More sharing options...
Jim_1979 Posted April 9, 2008 Author Share Posted April 9, 2008 Yeah mate. I've got about 20windows open, all about TTC mode. Reading them all at the moment. Pop outside and do it... let me know what it's like. I'm only considering it because I have a sticking EGBV or actuator. Quote Link to comment Share on other sites More sharing options...

heckler Posted April 9, 2008 Share Posted April 9, 2008 try TTC - i use it for sequential problem finding only takes 5 mins to do. Quote Link to comment Share on other sites More sharing options...

AndrewOW Posted April 9, 2008 Share Posted April 9, 2008 Love it, my car has been that way for nearly two years, won't go back. Would be good to have a go in that. Well as a passenger anyway! Sean1933 is going to attempt to convert mine to TTC again at the weekend, as he will be putting on another pressure tank (I think ). He thinks that I have a slight problem with the current one. If you get the fuelling right, then I can't see any reason why it wouldn't be a good mod IMO. Quote Link to comment Share on other sites More sharing options...
Suprash Posted April 9, 2008 Share Posted April 9, 2008 Im waiting for IanC to see this thread........ As far as I can make out it doesnt actually damage anything, but your ECU isnt mapping your fueling correctly until it hits the 4k mark wehre it expects both turbos to be online. Do a search and look out for IanC comments especially......but beware it sounds all very drastic, but as I said in practice, and people like Simon can prove this, its seems to be ok.....

Gaz6002 Posted April 9, 2008 Share Posted April 9, 2008 I loved it. Make sure you have a way of controlling the fuelling though otherwise it'll never run right. And you'll also need an EBC. IMO it's all about how you set it up. I found launching the car a lot easier in TTC and also found the power curve a lot more predictable and manageable.

Jim_1979 Posted April 9, 2008 Author Share Posted April 9, 2008 I have a EBC setup for the twin sequential system, would it need to be altered for TTC? Quote Link to comment Share on other sites More sharing options...
heckler Posted April 9, 2008 Share Posted April 9, 2008 I have a EBC setup for the twin sequential system, would it need to be altered for TTC? yup, as TTC can cause boost spikes (not good) - saying that, I have Blitz ID3 BC, and I dont get any boost spikes!

If you get the fuelling right, then I can't see any reason why it wouldn't be a good mod IMO. Like i said no problem mate, maybe at the next Brighton meet, The best way to do TTC is by wiring open the IACV and the GCV that way you don't have to worry about pressure tanks and VSVs, as for getting the best out of TTC at the least some form of fuel control is needed, you need to remove quite a bit of fuel in the midrange, thats why i prefer to use Emanage ultimate, as you can also advance the timing where the std ECU retards it, as its expecting the first turbo to be making boost. Oh! and as for it causing spikes, not if your using a decent boost controller set up right;) Quote Link to comment Share on other sites More sharing options...
tucky40 Posted April 9, 2008 Share Posted April 9, 2008 Hi mate, I also had the ETTC mod done recently when fitting an emanage. I switch between the two when i feel like a change and I love the TTC. The only reason i dont leave it in this mode constantly is due to the fact my car is mapped for sequential operation. I prefer TTC...... with sequential i would get both turbos online and full boost around 3800-4000rpm. With TTC both seem to be online and fully boosting at around 3300-3500rpm. Most sequential fans will say you'll have too much lag with TTC but with both turbos on song 500rpm earlier you also have much more power earlier. It definately is a better mod with a manual car cause that way you can be much more selective with the gears, rpm and therefore keep your car in the power band. I would be concerned running the TTC for a long time with the standard ecu as the fuelling will be all over the shop. If i were you i would do the quick TTC mod which takes no more than five mins, if you like it then i would get some form of fuel control and map it that way and release even more power. You car will boost higher with TTC, it added about 0.15 bar when i switch to TTC therefore be careful you dont over boost. If you are set at 1.1bar now you will see over 1.2bar with the TTC mod. You'll find that you wont feel the thump of the second turbo as you do in sequential but it will be a more progressive surge of power when the turbos come in. This may not give you the same feeling of urgent acceleration, although it is just as fast, but in my opinion it makes the car much more drivable especially if your bpu and in the wet. Have you checked out Cheekymonkeys dyno plots comparing the two modes?? These results speak for themselves and show what gains you can get when TTC is mapped properly. I will be getting mine mapped for TTC so i can keep mine in that mode. Ben Quote Link to comment Share on other sites More sharing options...
