a little bit of help needed before track day

Post by martysauce » Tue Apr 12, 2016 8:38 pm

hey guys i have a track day coming up on the 28th of this month , my 1st time on the track so should be fun. Anyway i took my car for a drive up and down the road which was the 1st drive since the engine swap. my tt z32 seemed to go great all tho the brake lights didnt work, the tail lights worked just wouldnt light up the brake part of the bulb. secondly when it got to about 12.4psi of boost she seemd to sort of bog down, not miss or anything the power just felt like it disaperd, any thing below 12 and she was all power. and thirdly i have a innovate lc2 wideband installed which just flashes 7.4 all the time even after i calibrated the sensor iv had a look and seems to be a shaged sensor code but i cant confirm it. any help from some of you z32 gurus would be very appresiated and wish me luck for the track should be great fun :D :D

Don't have allot of experience with TTs
I would check the brake switch on the pedal for a start for the brake lights
What fuel are you using? 91 octane?
My thought is the compression with higher boost might be to high for low octane fuel
Just some thoughts
Good luck

See ya at the trackday marty. Im assuming its the Christchurch Trackday one. your brake lights are most probably because the Brake light fuse has been bypassed? can you do stand still burnouts? the easiest way to do them is to buypass the brakelight fuse. its a little bit more complicated than that but its not that hard if that makes sense. as for the rest of it, dyno tune. highly recommend Rapid Performance in Timaru. Worth the drive. Great team down there. Best $1000 bucks you can spend after an upgrade like yours.

Its through a university club called motosoc not sure if its the same thing. I sorted the brake lights turns out the fuse was gone all together chucked one in and they worked fine haha. I droped the boost to 7psi and went good so il turn it up to 10. Dyno might be an idea but the engine swap was temporary till i rebuild my old engine
