Actuator preload is set correctly, i.e. the max preload requires the actuator to be extended 4-5mm to sit on the flapper?

 

Fiucked if i know, i just twisted it heals and used a compressor to get it o n.

About 5mm more than what i had, so we are seeing a big 28+psi spike the WGDC brings it back to 1.7bat(24psi)

How the **** do we stop the spike, but increase spool?

 

Ahhh. Increasing turbocharger spoolup while eliminating boost creep/overboost/boost spikes, etc.

 

The slow spool, low rate of spool, laginess, etc. Is related to the adjustment of WGA spring tension("preload level"). This part of the scenario is not directly related to the overboost issue which is independent of the the turbo's slow spool. So, you have to address each issue separately.

 

In my experience, since the turbo is creeping at relatively low levels of WG spring pressure, then you need to address the creep issue and eliminate it first.

Once we solve the overboost(creep) issue then we can increase WG sping tension to improve turbo spool w/o overshooting your target peak boost level. COMPRENDE?

 

What do you reccomend to start looking at?

 

Slow spool & boost spikes are usually caused by the same culprits the WG &/or leaks. Try it & install a different WG.

You could post a copy of your rom & perhaps a couple of wot data logs to look at.

The BOV, probably has nothing to do with your issues, but I suggest you install it in the right position & you should see some improvement in response (especially in between shifts) you're likely to lose 1-1.5psi boost which you could compensate through boost control.

 

I have put the boost leak tester on, Replaced throttle body gasket, shafts seals and the other o ring in the throttle body. there is no leaks. I originally had the 18PSI FP wastegate which would only run 1.2Bar, was reccomended to go a Kando Dynamics 1.7bar to help with spool and hold boost up top.

Then put a 3port controller to control boost through ecuflash.

Im sick of replacing parts and nothing working.

 

Its only started overboosting when i increased the spring tension

 

hmm it wont let me attatch the logs

SPARKY, WHATS YOUR EMAIL?

 

Put the .csv log files in zip file & attach it, it might be helpful to attach your rom too.
