I'm not sold on fiddling with VNT actuator adjustment trying to control the max spool rate and peak boost. Cheers It's actually quite easy, have done it 4 times now and can do it in less than 30 minutes on a cold engine and that's where I think the fuel eco in high boost mode is coming from, less aggresive spoolup with no loss of performance. The reason this is done is to take control of the boost away from the ECU, which will make the boost jump around and in some cases drop right off, this may result in very high EGT (the boost on my old girl would drop off to 2-3psi at around 115k then on hitting a hill and powering the EGT would skyrocket, later model ECU's did have better ... Just a quick video of how I plumbed the needle and Dawes valve on my 2002 Patrol 3.0 Di... The Nissan ZD30 engine family is a 3.0 litres (2,953 cc) inline four cylinder diesel engine with a bore and stroke of 96 mm × 102 mm (3.78 in × 4.02 in), that replaced the Nissan QD, BD and TD engines. this is where the boost line will be routed from, instead of the weld-on fitting shown in a later photo. STANDARD VACUUM Remove this hose from it's spigot under the intercooler. This is the vacuum source for the Tillix system.

May 08, 2019 · So running at full turbo boost, with not enough fuel delivery causes excessive combustion chamber and piston temperatures, which caused the ring lands to grab on the cylinders. The airflow meter in the ZD30 can also be attributed to the cracked pistons that these engines suffer from. Oct 05, 2012 · The correct amount of oil for the Di ZD30 is 8.3 Litres. 3. Overboosting. The ECU on the early GU patrols doesn’t control the boost very well. The GU patrol has a Garratt VNT (Variable Nozzle Turbo). The way this works is – the pitch of the blades of the turbo are changed to create more boost at lower exhaust pressure. The ZD30 engine has suffered a poor reputation for premature failures including melting/cracking pistons and overboosting, largely due to some common issues. These engines run a variable vain turbocharger with boost controlled by the ECU, and to meet stringent European emission standards run an exhaust gas recirculation (EGR) system. February 2012) While the ZD30 engine has a boost sensor, it plays no part in fuel mixture control. The ECU will reduce boost when it gets too high, but this system is very slow to react and boost spikes of up to 25 psi can happen. This turbocharger boost is controlled by a vacuum solenoid using pulse-width modulation. By rapidly switching it at May 09, 2020 · A boost controller controls the amount of manifold pressure by changing the amount of pressure going to the wastegate. For example; if you wish to increase your boost pressure above your standard wastegate actuator pressure (typically 7psi), the boost controller must acurately modify the pressure signal the wastegate actuator receives by venting an adjustable amount of pressure, forcing the ... Nov 24, 2016 · But re-plumbing wastegates isn’t something that you want to be doing while you’re paying for dyno time. So let’s get it right. And to get it right, we’ll make sure you understand exactly how the boost control solenoid works, and how the wastegate you’re using works. First of all – let’s look at how a boost control solenoid works. I'm not sold on fiddling with VNT actuator adjustment trying to control the max spool rate and peak boost.

May 08, 2019 · So running at full turbo boost, with not enough fuel delivery causes excessive combustion chamber and piston temperatures, which caused the ring lands to grab on the cylinders. The airflow meter in the ZD30 can also be attributed to the cracked pistons that these engines suffer from. This “assisting” of the factory boost control allows a linear boost curve. If your ZD30 is an early pre 2005 DI then you should bypass the ECU controlled Vac solenoid, if it’s a much later model (common rail diesel post 2006) we still recommend the procedure to settle the issue once and for all. Early ZD30s have their turbo boost drop off ... Driving a Nissan patrol with the ZD30 motor ( grenade) I fitted a Dawes manual boost controller and a needle valve. The Dawes device has enabled me to control my boost . I have had it fitted now for 4 years and have never needed to adjust it. Great service great device. Would recommend to anyone who needs to control their boost. Jan 03, 2016 · HPD VNT Boost Controller - Suits Nissan Patrol - ZD30 - DI and CRD. The High Performance Diesel VNT Boost Controllers have been designed and created to suit Nissan Patrol ZD30 CR's and DI's, as well as all vehicles with vacuum actuated turbo's.

The turbo boost is controlled by the valve on the intake which is in turn controlled by the ECU. If one connects the vacuum line from the pump directly to the turbo, (bypassing the control valve ) every thing works well and the ECU has no control over the turbo. Except that the vacuum is a bit high and therefor boost is to much.

OK - Have gotten this Patrol running better and fitted EGT & Boost gauges to monitor the grenade under the bonnet. I have been reading and taking in a shit load of info from the Patrol 4x4 sites on the ZD30 and all it's issues but would like to see what some of you guys have to say about it (other than piss it off as money & Misses won't allow it & I actually like it other than its engine) The ECU of the car is RE-MAPPED on the dyno to give us the best result for Boost, AFR and drivability. No plug in modules or chips are fitted, all changes are made to the factory ECU itself. Remember that performance gain is a result of improvements made and should not be the ultimate goal over reliability.

By rapidly switching it at Apr 06, 2015 · TC Boost Control Solenoid Valve Like the previous ZD30 engine on Y61 & the YD engine in R51 & D40, the Turbo Charger is a Variable Nozzle Turbo. Vacuum is supplied to the actuator on the turbo. If a high level of vacuum is applied, the actuator rod is forced to lift which in turn allows for maximum boost.
