I just hope so !
because Ive been dealing with Ign timing problem since last november,,,

As soon as I get the car , I will do some datalog to see if anything changed !
knock sensor were detecting to much noise.

wow thats crazy. Finally got mine back today.

what mods did you do prior to November. Looks like you've done all the mods yourself.

Flywheel pulley?? Isn't that related to flywheel

Cracked flywheel, wow! I'm glad to hear that they didn't blame the flywheel damage on your lightweight crank pulley. Since the after market pulley doesn't include a harmonic vibration damper like the OEM pulley I would expect them to say that undamped crankshaft vibrations caused the flywheel to fracture.

Update !

The mecanic at the dealership called me earlier and told me they went for a test drive after replacing the cracked flywheel and the seal .

THey are now ordering a brand new transmission which is also Back Order.

Thats good news. New transmission.

Great news but the wait is gonna suck

Update !!!!

I got back from an military exercise in Wainwright (Alberta , Canada) a week ago!
So on last Saturday I went to the dealership to get the Z back !

the complete repair list was principally the flywheel which was badly cracked and the blown transmission.

The service guy called my at home while I was away on exercise and told my GF to take it easy on the new tranny for at least till next year !! and told her no more track time for this year !

2 days ago I went for a ride after about 800kms done on it and decided to datalog to see if by miracle my IGN Timing problem would be changed.

The first pull on the 4th gear up to redline , I saw the timing going where it was suppose to be around 29+- 1
I was surprised and decided to do one on the 5th gear up to 7300rpm
still the same thing !! I hit 29 which was perfect !
and then yesterday I decided to do it again just to make sure of the result that I had the previous day!

I'm very pleased that the knock sensor are now happy ! it was probably due to the cracked flywheel making too much noise which I couldn't hear or see the difference with the headphone knock listening device (Uprev)

0-100mph is now .5sec faster

before sending the Z to the dealership I removed all of intake system & removed Uprev incase they wouldn't like to see the car fully modded !
so I'm even more surprised !

today I'm going to datalog with my custom CAI and restart the tune (Uprev tuner)

Glad to see that things are back in line for you!

Thats good news to hear.

UPDATE !!

today is when I start tuning the MAF Table in Uprev for my custom oversized CAI
after taking the datalog that I need from 2.7v. to 4.3v ( at WOT )
I decided to do a quick run from 0-120mph (0-193km/h)

the AFR target is 13.25 everywhere while Im tuning the MAF Table and it need more adjustemnet ,, the graph show from 12.9 to 13.7 along the powerband (on my aftermarket Wideband it would be +0.4 to +0.5 leaner so in reality it was 13.3-14.2) ,,, I know on the Dyno I can get atleast 5-10 whp right there

Before, with the cracked flywheel for the past year (november 2010 is when it showed on dyno)
FULLY MODDED ,, = intake/exhaust/tune/ everything !
Datalog taken from Uprev
0-60 mph = 4.883 sec
0-100 mph = 11.607
0-120 mph = 16.958

40-100 mph = 8.767
40-120 mph = 14.118

Then after I got the Z back from the dealership which replaced my blown tranny and the badly cracked flywheel

4th Nov
No intake MOD ,, only Exhaust and Oversized Throttle body using the OEM tune ! not even flashed
(afr 11.3 -11.8 ) (using my wideband it would be about 11.7-12.3 AFR )

0-60 mph = 5.1
0-100 mph = 11.1
0-120 mph = 16.4

40-100 mph = 7.784
40-120 mph = 13.088

Today !
Complete exhaust + CAI + oversized throttle body & Uprev while I tune it ,, which isnt finish at all !!!!! but getting closer & closer.
AFR is quite lean so more power can be seeing once the MAF is tuned
0-60 mph = 4.587
0-100 mph = 10.468
0-120 mph = 16.037

40-100 mph = 7.862
40-120 mph = 13.431

the Z is getting faster and faster !!!!
I must beat my last time at Napiereville (Quebec , Canada) which was 13.175 at 104.33mph

Glad to hear :tup:
