Hey, got a question.

Say I'm slowing down and I'm gonna select a lower gear, if give it a boot full to match the revs with the lower gear it can hesitate or feel sluggish with the clutch in free reving.

I have a lightened flywheel aswell so it should respond to my commands quicker than stock.

Vacume leak?

Dirty afm?

Tune?

What is the wideband reading when you back off? Does it go lean then rich? The turbosmart reg should be fine unless the fuel pressure is set high.

A lot of that light load tuning can be difficult to do on the dyno, if you have the software I would suggest having a play with the lower end of the map yourself if you are confident, or asking your tuner to clean it up a bit.

Also make sure o2 correction is enabled, so the ecu can self tune the light load areas. The fuel requirements can change constantly with the weather otherwise.

Afr is lean when I back off, I'll check if it goes rich again,

Fuel press set at stock. 37.5 from memory.

The only tune I hav was road tuned via the internet. (I live in the desert)

I have all the tuning gear but inexperienced

The O2 was disabled and it run dog rich,

When I enabled it it cleared up a lot of problems

It's 14.7 in most cruise situations although it was around 16 straight after tune and then changed to 13.5

      I think the pic in the first post is another car, and post 7 is OP's car with standard arms and swaybar swaybar swaybar. I can't tell what brand the silver coilovers are, and even if I could I don't know whether the spring rate is OK, if you can find a brand on the shocks and numbers on the springs that might help. Also, if you can measure the ride height from centre of your wheel to the guard that will help with advice too as handling suffers if ride height is too low

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info

      It looks like you've got Ikeya control arms and an aftermarket sway bar, maybe whiteline?  Or am I just going crazy? lol Unfortunately it won't, but what it will do is look really pretty. That's about all unfortunately.  How much neg camber do you currently have? Generally lowing the car dials in quite a bit of neg camber as it is. If you do go down this path, your best bet is get adjustable arms, toe arms (or preferably a good HICAS elimination kit) and traction rods. With all 3 being adjustable, you'll be able to dial out any bump steer that is introduced by playing with the camber settings.
