Only work Saturday mornings , but if you was with us for 8 I think I could get 2 cars done before 1 when we finish.

The larger figure is the hub torque we then divide it by the effective final drive ratio to get a flywheel figure.
Bradley , good to here your happy. enjoy. Car wasn,t to loud either with the de-cats fitted.
3FIDDYZ car with the headers fitted gives a little more midrange torque and a few more top end BHP , sounds a little different as well.

Yeah we may need to dump the ECU , so maybe 2 visit,s. It,s a shame but Nissan do have the habit of using different images in there cars.

Lee,
I didnt say I havent got the mapping, I need either your chassis number or ECU to make sure
we have the correct RAM image. Auto cars have different RAM images to manual cars also cars with out cruise are different to cars with .
Can you PM me your chassis number?

Didnt they road test the car after carrying out the service?
-
2 cars in one day will be okay.
sure it will be worth it...... the trip from Scotland.

The cat in the Y pipe is of a less restrictive construction like a set of HFC,s, but easier to remove and refit.
Best of both worlds.

Yes that what I thought , you can run a CAT a silencer and a decat pipe.
Will run it on our car once it turns up.

HFC do work but we have also found running without cats is good as long as you have an exhaust system that is pretty quiet.We can turn the CEL lights out if you remove the cats as well.
I have been looking into using a Y pipe fitted with a removable CAT so we can remove the STD retrictive cats. But this wont happen before xmas, but I will keep you up to speed on development.

You lot of gone quiet re UPREV reflashes done a few more cars , still getting good results, not had anyone say thay aren,t pleased with the results.
They go up on the 1st of January thou just due to the VAT increase from £345-00 inc vat to £352-50 inc vat.

We think it threw a CEL on due to the battery maybe getting a little old and when the car was cranking the battery voltage went low enough to trip a BCM code due to low battery voltage , not seen this problem before , but there is a 1st time for everything.
We reset the CEL light , sent the customer on his way and told him to change his battery and keep an eye on the problem.

Jerry ,
has it cured the problem you had?
Mark

Might not be the induction system , we have found the crank trigger sensor which is at the bottom of the gearbox, gets wet and upsets the crank trigger output.run the car for a while and it should sort itself out , will need the car turning off and restarting thou to reset the ECU.
anymore questions fire away.
Mark

Yes I can if needed. Not done a 370 yet , but will do soon.....

Just been thinking that when we are asked to tune a JDM we need to check to see if we have the correct RAM image , we have asked for people to supply ECU number , but this needs either the ECU removed to check part number or take the ca rinto a Nissan dealer for them to look at the ECU via diagnostic port.
But I have had a think , if you supply me your chassis number we can check via our JDM fast parts system what ECU number part number that is fitted to your car.
hope this helps.

Ian,
I tried to ring you last week re talking to you about buying a 34 , left a message on your answerphone , give me a ring tomoz , I think we do know what we are talking about re GTR,s

It,s not BHP that kills the VQ motor when F/I , the motor has a week conrod , the fails when you try to run to much torque through the motor.
HKS say around a max of 360 lb/ft of torque (only a figure not a definite figure) on a STD motor.
A S/C conversion works best as it only enchances the STD output does not increase mid range torque a huge amount, where as a Turbo conversion alway gives a car a huge amount of midrange torue which will kill the STD con rods.
If HKS sold there S/C tuner kit a little cheaper and we can get around the LIVE mapping issues of the UK 276bhp that will be the way to go , I think around 400bhp flywheel and 340 ish lb/ft of torque would be pretty easily to tune the car for.
I am not keen either the Vortech ( to noisy) or the Procharger kits (inefficent) but the early and late HKS S/C work very well we find.

def sounds like a heat shield noise , funny thing harmonics. Best to get the ca rup on a ramp a best to remove the heat shields and try the car.

forgot to say we have the NISSAN consult for diagnostics.

Thats what we have been thinking re dyno day maybe sort something out mid Feb when hopefully the weather will start getting a little better.
If I could be a week day I am sure I can get 10/12 cars done , but if it is a Saturday can only really manage 6 cars I am afraid.
Mark

Do you want to go to a main dealer?
I am sure we can look after your servicing as good as a main dealer.

Chris,
maybe worth moving this to a seperate thread , good info for people to view.

This is a good comparison between the 3 350z motors
all 3 have been UPREV tuned
PURPLE 276bhp motor
DARK GREEN 296bhp motor
LIGHT GREEN 313 bhp motor
For a road car I dont think you can beat a well tuned 276bhp far more mid range torque.

Yeah they have an oil cooler fitted.

Up Rev re-flashes

could I have both of your full car spec,s will help me to build a couple of maps to be uploaded on the day
