That's because he had a short first gear for the new found power. If the gear ratios were changed it would nt spin. That's typical with tuner cars....stuff is always mismatched.

But that Skyline was a dream. It always had the right amount of power at the right time.

Thumb rule, What ever you want to do do it in ECU. But what?
Advance firing timing? Make the fuel richer? leaner?

Please prodon me If you feel I am really 1st grade boy in autos..
To get low end torque you need the following in the order of importance.

Forced Induction (either turbo or super charging)
More displacement (stroke rather than bore)
High compression
low lift and low duration cams (~)
long intake runners w/ smaller ID
long header tubes with enough backpressure
Ignition timing retarded (if unmapped)
AFR leaner than stoich

Rather than do all this, get yourself a Octavia TDI.

Default Re: How to improve lower end torque..

This is probably the right thread to talk about how poor the low-end torque of the Honda Jazz is. I already have gained a slight bit on the low-end by installing a CAI, but it's still not enough. I am already contemplating a full SS FFE system. What I need is something that can make the car pick up faster at 2000-2500 rpms. My majority driving is in the city, and I care less how much time the car takes to reach triple digit speeds. What do you guys suggest needs to be done?
