The turbo response is also controlled via the PID closed loop control ( this is control via RPM/throttle/load) so this can be tuned with a front wheel drive car we also sped a lot of time with the throttle boost control so removing some throttle input lows the boost this will soften the power delivery making this to aggressive will de-spool the turbo thou Also the turbo response is control via the cams as the inlet/exhaust cam are variable controlled (again closed loop) these can be tweaked to help/control response. Advancing the inlet cam at low rpm/load will enchance the spool as I said we can make the response to aggressive. Nissan use a very complicated throttle control calibration, slow to fast maps speed threshold maps load maps on EcuTek these are all adjustable(tuneable) where as UpRev is way way behind on this part of the Nissan tuning, this makes all the difference a throttle open will make boost far quicker but we can calibrate the other parameters to make the power delivery softer even thou we are making boost. lots of things can be used to help spool. We can see full boost on the DIG T at around 2500rpm if we want to. Full boost is around 1.25/1.3 bar boost.

Yes tuning the cam control/ boost control and retune the throttle maps will sort the response issues. Nissan seem to have dulled the motor on the QQ it seems. The 2wd Jukes we tune the car to remove to remove torque in relation to throttle position as these are are too aggressive.

Nissan 370Z tuning with ECUTEK and bolt ons
Mark@Abbey m/s replied to Mark@Abbey m/s's topic in Abbey Motorsport
Hi, Yes got your email. Afraid I have been on holiday since last Friday back on the 4th. Your are registered for the discounted price. -
We have been tuning the Dig T and Nismo Juke's for a while. Get some real good gains from them. Beavis you QQ is de-tuned from the Juke Motors, really need a ECU dump from your car to or the guys @ EcuTek sort out the base tune. You willing to do this can sort a very good deal out in return for a base tune.

What engine to fit in my car with a damaged engine???
Mark@Abbey m/s replied to cearnshaw85's topic in 350Z Technical
Hi, A Rev Up motor will fit as long as you have the complete engine loom and ECU. Just have the NATS turned off then a bolt in job. But we have found that the Rev Up Motor is more prone to using oil than the DE motors. There was a re-call on the Rev Ups for oil usage. The DE is a strange motor, low mileage doesn't always mean it is going to be a good motor these engines do suffer from oil usage, the issue comes from the oil control rings lose there springiness so don't clean the oil from the bores. We have seen high mileage abused motors that use no oil at all. Compression and cylinder leakage tests won't show this issue. If the car runs Cats it won't be shown with oil smoke as the cats clean the oil smoke running without cats will show with blue oil smoke. Personally I would have a motor rebuilt may cost a little extra but you know the motor is fresh and known. -

USED BERKS 350Z HR/370Z High Flow Cats

bump to top priced reduced to £150-00 shipped. payment via paypal please -
djtimo you got Syvecs fitted and tuned yet on the Zed?
-
The only thing wrong with the DIY install is the car wont pick the fuel up from the other side of the fuel tank it needs the fuel pressure to be returned from the return pipe where the stock fuel pressure regulator is situated like in the CJ kit to syphon the fuel across from the side of the fuel tank without a fuel pump. Good info thou.
-
It isn't just the fittings you need; As people had said the fuel pump module needs modifying; it does a lot more than just hold the fuel pump; Snippets from CJ web site; Far better to buy the kit from CJ and everything work. I feel it is a PITA to be in and out of the fuel tank One thing buy a new fuel pump module sealing O ring they absorb fuel and swell up making them a right pain to fit;
-
Not as easy as just drilling the rail Tricky. Need all the stuff to convert the fuel pump assembly. Fuel return line as well and a fuel pressure reg 50 is completely different to a 70 as well.
-
Easy job. What input you going to use? Let me know what you want to do.

VQ35HR - Intermittent misfire, no errors
Mark@Abbey m/s replied to Commander's topic in 350Z Technical
Commander, Hi. Where are you based in the UK? -
Big torque number is hub torque. Basically engine torque X drive ratio (gearbox X final drive) = 4.631 Divide hub torque by 4.631 you get flywheel torque.
-
Bobby what are you thinking then? The HR gives a much bigger spread of torque then any of the other 350Z motors and with normal bolt ons will give 270/280 hub bhp easily , I have tuned a HR with PPE headers (don't know if there where the cheaper or more expensive merged collectors thou) car gave 290 hub bhp I seem to remember. Again stock air boxes work best we have found.
-
the throttle pedal isn't connected to the butterfly with a cable , as Olly has said the car is fly by wire so no hard connection between the pedla and butterfly.
-
I think you may see around a gain of 10bhp though out the rev range; Limiting factory will be rev limit , these cams will make the car want to rev on and the stock Alloy valve caps wont allow more than 7100rpm we feel.
-
Some people Ray's fit over the 370Z brakes others say they don't Olly. Even running spacers may help the Rays fit.
-
None of the DE(278bhp) powered cars where facelift models. Facelift was brought in for the RevUp(296bhp)powered cars. The GT4 model cars had early dash trims and early front bumpers. The normal edition cars had facelift bumpers and updated interior trims.
-
Sorry but to fit cams into a 350Z motor is a lot of money , easier to do with the motor out in our opinion; Then if your running wild cams you need to run more compression as the static compression will be dropped as the cam is wilder; new pistons needed; I know Sasha when he was running his own company used to tune on a Dynapack. Used to throw idea between us. They used to use SAE conversion which will add around 10/15bhp to a bhp figure; Your end up with a motor with a engine with a 2000rpm power band max that will not be nice to drive at small throttle openings and low RPM's , will require rev to make it go properly; That's why us UK tuners always say go FI makes a more fun car easier to drive quickly on the road , but if the car is going to be a track car/race car yeah go for NA power but your also need a sequential gearbox to make the most of the narrow power band. I did manage to run a car on our in house dyno today and recorded Vac in the plenum , reading in Absolute KPA we saw a increase in Vac from 0 to approx 0.003 kpa at the rev limit such a small increase , my thought is it the TB or the plenum design; Same car recorded 270hub bhp thou pretty good number for a DE motor , circ approx 310 flywheel bhp , stock motor , headers, ART decat pipes, plenum spacer,stock airbox with velocity stack, Milltek system and a very good reamp with UPREV. a Stock DE will give around 235/240 hub bhp we have seen from all the cars we have run over the years.
-
rev up is just a better quality pump gear materials no different in flow. Nismo has increased flow over stock DE/REV UP oil pump. I will check a DE for a VAC at full throttle when I next get one on the dyno for a retune. thanks
-
Limiting factor in DE rev wise is valve Spring retainers and collets. Seen failures at 7100/7200rpm when used on track. Spring retainers are alloy in stock form. Stock rods will go to 7500rpm no troubles in NA trim. High RPM will cause oiling issues as well.

at wide open throttle?
