Mark@Abbey m/s

see my above 1st thread.

All the good traders, Cougar,Clarke,Tarmac and Abbey Motorsport will carry these in stock I am sure. thanks I apologise for not listing every trader on this forum.

Thanks again for the feedback. Pleased the Uprev software and the Abbey calibration has made your car a better drive. Mark

Thanks Graham. We get most of these jobs from garages that are servicing these cars.

Ecu has been damaged due to a garage cleaning the throttle bodies (opening the Throttle plate) without disconnecting the battery and disconnecting the ECU. The causes a feedback that corrupts the Idle calibration that is held in another EPROM that can't be re flashed using Uprev software. Idle EPROM is reflashed to allow the idle control to work correctly. Happy customer, we also have sorted out what causes the HR hesitation and using the excellent Uprev software we tune around this issue. So please don't clean the throttle bodies on your HR or VHR without disconnecting the battery and Ecu. Pleased we have another happy customer with a NA Zed tuned on Uprev.

yes engine out , total strip and rebuild.

The cast piston fitted to the 350/370z HR/VHR is the weak point on these Motors.

so what item is causing the noise at the moment? the ball joint (at the hub) or the rear bush onto the subframe?

Are you running SPL Front comp arm rear bushes? If so they will never be quiet. I use them on our heavy duty track cars/race cars and they are normally noisy straight away. I would always use Super Pro bushes nice and quiet and will last forever I would say.

So if you don't have a donor long block motor you can ship to the US you have to pay the surcharge on the engine supplied by the engine builder. The motor you get back needs all the timing parts swooped over. Duty and VAT will need to be added to the parts used in the rebuild of the motor prior to importing the motor back in and if pay the surcharge you have to pay Duty and Vat on the long block as well as all the parts or the entire build if it is listed as a full build. I doubt it will be half the price of a motor built in the UK. remember Andy was talking about a drive in drive out job not just a forged motor supply.

Just buy a GTR, swap the Y pipe out and a remap 580bhp 550lbft awesome gearbox. :-)

Yes it will.

it isnt about how much fuel you can run it is all about cylinder pressure/ignition timing. Running lower compression means you can run more ignition timing so you dont struggle with high Exhaust gas temperatures. We lower the dynamic compression with a DE motor by playing with cam timing and increasing cam overlap.

S14DST is located in Luxembourg. thats w ehe has a LHD car.

no we thought it was restricted int he lower 3 gears but it is the response that is different in the lower 3 gears , as I say the elastic throttle cable is more stretchy in the lower 3 gears than in the upper 3 gears.

no trouble to supply Uprev cable and a good base to start with. As long as the car has wide bands fitted I can E tune the car via datalogging. Although some people say they cant feel a difference a lot of people are very happy after tuning with Uprev. PM or email mark@abbeymotorsport.co.uk thanks

Colin, good to see you hope the trip back up north was good and give me some feedback on the Uprev tune on your 370Z please. Thanks

Although the injectors test good re capacities the spray pattern isn't good when we ran the car on our dyno and measure AFR on both banks you can see the car go lean on both banks in the below screen shot this corresponds to the datalogs from the car lambda's as well

other issue I have found that we think my be the cause is that the base fuel pressure is set very high. After talking to a friend off ours that tunes a lot of VQ's in the US we feel the stock dampers cant cope with the high pressure , next job is to see if we can wind the fuel pressure down to the pressure we use @ Abbey when using the CJ fuel systems.

Hi, only real way is to read the ECU this will tell you if the ECU has been programmed If you email us the registration number I can look if we have tuned the car. thanks

Stock Zed engine loom and throttle pedal needed together with stock ECU. Extend throttle pedal wires from ECU to pedal few wires and relay needed to make the motor run. We can remove NATS from the ECU so no need to have to bid the stock key and key reader box/loom. Have you brought a motor yet?

Motor vehicle technician required for family owned garage that is well known within the Japanese tuning industry. Must have experience of working in the automotive industry and experienced in all aspects of servicing/repairing motor vehicles.

Good salary, dependant on experience email or PM if interested

Going 370Z brake set up then?

We see a lot of 350Z's with the Cat shields rusting and falling off. I would say around 50% of the car we see for service we remove the heat shields to cure rattles. any questions ask away

If your having a an Uprev no need for CEL Fix as i sort that with DTC tweaking; forward the last email you sent direct to me please mark@abbeymotorsport.co.uk I will get it sorted. Thanks
