My Car Just Went Bang

[hypergear]

Suppose to have a loud suction noise, that’s affects from FNT turbine setup as the shaft spins at faster rate compare to generic turbine based on same RPM scale.

I've sent you an additional low pressure actuator. Swap the high pressure actuator over and it should sit the boost to around 10psi. But recommended to keep the high pressure actuator if the car's going to be tuned with supporting mods.

High pressure actuator will also pickup better response.

What engine management are you using?

[lilcrash]

Still using stock ecu, no one wants to install a nistune and tune my car apparently. They won't return my emails. Their loss, il just install it myself and get it tubed at the first 4wd dyno I find that looks like they know what their doing.

[wolverine]

Who won't return your email?

ps. I would be taking it easy on that new turbo until you get the Nistune installed and tuned and it is easy enough to remove the front driveshaft and use a 2WD dyno.

[lilcrash]

Gavin woods autech and mercury motorsport. The turbo is only making 5-6 psi so it's not worth me trying to go fast. It's just a waste of fuel.

Blew an intercooler pipe with 5psi? Did you forget to tighten it up?

[lilcrash]

No it blew off on the way to 20ish psi with the high pressure actuator on. But yer the hose clamp missed the end if the pipe.

Send Matt (nistune owner) your ECU and get him to install the chip. I can give you my Nistune file suitting 550cc injectors. Load that up and it should start and drive as if its been tuned assume you have the same injectors and Z32 AFM.

You can drive that to your tunner and do a quick check up making sure its not pinning or doing any thing strange.

[kwickr33]

So how did it actually drive on road compare to the stock turbo? I've noticed you've been running 10psi on factory turbo till it blew, have you tried 10psi on the new turbo yet?

Ive got the small actuator on it now and it's as tight as the adjustment will go, it's running a pretty constant 7 psi but high in the revs it has a very sudden spike straight to boost cut so 14psi. It's very annoying as down low where you want the power it won't get full boost. I'm hoping it's just the actuator.

[pipster11]

This new Turbo will flow more air so you will gey afm cut at lower boost now

On 7 psi I get near 5.0v on the stock Turbo, you may be maxing out the afm voltage

[lilcrash]

My boost gauge is reading 14psi when it happens. It's actually settled down a little. I'm wondering if I have a boost leak. On the way home from work it would gets the usual 7psi but from 4500 it slowly built up to the 14psi limit and shut down. Either it's a boost leak or there is a problem with the turbo. It is strange that it won't boost above 7psi until the boost creep starts. I will re install my boost control and see if I can turn the boost up to my normal 12psi. If it doesnt work il have to contact stao.

[pipster11]

Are you sharing anything off the boost line to the actuator? Just try running a new line from the manifold to the actuator with brand new line

[wolverine]

Is the wastegate able to open enough with all the pre-load?

[lilcrash]

Ok with the wastegate pinned open it is making 16/17 psi. Problem solved

Wastegate too small???

Error code 26: boost pressure sensor, engine started twice with this fault.

[pipster11]

pretty sure thats the little black box that sits on the firewall above the motor

its a map sensor and once that sees 1bar it triggers a fault in the ecu

[QWK32]

Have you unplugged the sensor or removed it completely? Ecu will throw this fault if the sensor is unplugged.

[lilcrash]

I thought that much . As far as I know it is still hooked up unless the boost has blown the vac/boost line off.

[lilcrash]

I dont want to start a new thread so anyway.

Does anyone know if my blatz consult cable work with nistune?? I now have nistune maps for a z32 and 550cc injectors now but still no nistune or injectors or walbro or afm until I get my tax back
