Just wondering why TTC was terrible on the stock ECU ? :(

 

I'd like to do TTC on the stock ECU?

 

If I had to start dumping extra money on ECU and some other stuff, I'd rather hold off and just get a smaller single personally.

 

I believe it's due to over fueling

Yer with the traction control, knock sensor and mapping was about £2250, and yep its well spend as its all prep for the big single :)

 

Hi Samurai. Ryan suggested TTC as it works great with the Syvecs unit. I did hesitate as it was god awful on the stock ECU.

TTC on Syvecs makes it a much more predictable car. You don't get constant surge of power when its not needed. The turbos kick in around 2-3000 RPM so not much lag at all. But with Syvecs you get launch control so theres no real problem with lag.

On the plus side with the 1st turbo being off on low revs it saves a little bit of fuel. And the exhaust is a little more growling with the wastegates open on the low end ;)
