300Zx De+Tt Conversion

[Super Drager]

Didn't exactly know which section to put this in so i'll put it here. In the upcoming months i'm doing a DE+TT convert on my NA 300ZX. However, i have a question i need answered. I was planning on using a stock TT Ecu till i could get the nistune on there and tuned, however it seems the timing maps are about 4-5 degree's too aggressive in the high load area's of the map especially around peak torque, thing is there will be a Coolingmist Water/Methanol injection system going on..... will the WMI be able to prevent the engine from pinging? Only plan on running 7psi till i get the NIStune tuned for the WMI then the boost goes up.

Not too experienced with the 300zx, but can you retard the baseline timing?

Also, you can just drive it accordingly, it will only boost 7psi if you make it.

Yep, have a consult display that can retard/advance timing across the board.

does the vg30 run an adjustable CAS? if so then you could also dial the timing back with it.

and since it needs to be said, doing the TT setup will require..................

wait for it...

engine out. YEAH!!!!! *puts on sunnies*

[Super Drager]

It will need the engine out, have to use the TT sump Yeah adjustable CAS, so if i drop it back to 10 deg base timing other than losing power will there be any other side effects?

should be ok but run it up on a dyno to be sure

make sure you arent using bog stock turbos so you dont need to do this twice

Other then the fact it won't be running as efficiently as it should unless you're right up it... No... Oh, that also means it will drink fuel.

Get a full standalone EMS as soon as possible!

why not wait that little longer and get a nistune straight up that way its not a stuff around

[Super Drager]

Yeah i just got another job, so i probably will end up going that way.

if it is an auto tt ecu, mayby. auto runs mor timing) but just put it in. it will be fine. they are way rich/safe from factory. there is quite a large margin for it. besides the fuel today is a wee bit better than in 1989..

Sweet, yeah will be taking it to Unigroup Engineering or UAS to get tuned. Be cool to see how high the boost/power goes with the water/meth.
