we are finding the stock headers are pretty good , get rid of the stock cats thou, these hold the motors back top end. Been playing around with the Gen 1 ecu cars like yours running them in open loop works real we find.

mmmmmm nice write up.

reflash!!!!! but I am biased

why bother stock airbox is sealed to the front panel , picks up nice clean cold air. Fit a 06 airbox carbon panel in bumper works the best. Dont pick up up from a low place real easy to suck water in then. Mark

O6 airbox is worth 4/5 bhp over a stock early box even better with a remap, gets cold air all the time far far better than under bonnet air filter kit made. Long tubs kits we find the Ignen the best , the AEM doesn,t seem to work as well. Mark

When running full throttle the air con clutch is turned off...even if you have the air con turned on......not worth the hassle to be honest.

Cars is almost back together now, been a little longer than I thought due to work load at my body shop. I think this car wont have a S/C fitted , kind of want this car to be a demo car for the stage 1 conversion like most people will want. But I have a feeling that our JDM car may gain a HR motor and maybe a pair of blowers sometimes.....

Car run on the dyno , stock RAM but fitted with a few bolt on parts Your see the car improving as the runs count up. Red line is the 1st pull. shows how the cars self learn. Mark

Jez you cant play with any of the traction/ESP yet with the Uprevyet but from what I have found out the UK car,s are different from any other 350Z made/sold, bloody typical of Nissan UK. Welcome to the Z world thou Jez better start locking my maps thou Mark

Nurrish , send it to me please. Mark

Glen, just nipped on here to pick up a PM, I am away from the office tomorrow out testing with Mr Lizard @ Mallory , when I am back in the office on Thursday , I give you a detailed answer to all your questions. Mark

Glen, we have done loads of cars now , got a real good base of maps to use on cars. Looking at your list mods , I would say around 8/10 bhp and the same increase in torque if the exhaust is a good system. The throttle response your be amazed at makes the cars come alive. I would say the car gace around 276bhp (stock) the last time it was run @ TDI , we do a base set up run before we reflash thou. Prices is £352-50 inc vat. Mark

Mr Lizard, we use a HKS filter not Blitz. cant fit a Ingen filter to steve,s car due to oil cooler placement....;-( Mark

Motordyne resonated decat pipes are £521-00 inc vat , well worth the extra bucks. They sound awesome when fitted with a Gamma MD exhaust system.

You can play with the cams as well as the fuel/ignition maps to try to get the best from the car after removing the cats. But we have never found or tuned a car that will have more torque low end without cats than with cats weather they are stock or high flow , but the new MD resonated cats do give the car a little more low end torque but make the motors DE/REV_UP give stonking mid range grunt. I will get a set on a car with headers fitted DE motor very soon , I think we will see lovely fat midrange torque curves and a few more BHP top end as well. These seem to pull the max bhp rpm down as well which is good.

Fitting fully de-cats will always give around 6/7 lb/ft and 6/7 bhp on top of a car tuned with UPREV with Stock cats. And sound great as well We have used the new Motordyne resonated de-cats , these give real good mid range torque and no lose at the lower end of the power band. I will post the price up on the Motordyne thread. Mark

I have a pair of those Scott, need to speak to you re some other parts for my UK car. Mark

I post up the gains tomorrow when I am at work, pulls always in 4th gear.

it,s on his 1st post above. lower numbers stock higher numbers tweaked! Yes , just added HKS filter and the remap. Mark ( sorry to hi-jack the thread but I cant sleep......to much super unleaded in my lungs)

HR cats are being developed as we speak , flange set up is different between the DE/REV-Up and the HR cars not a easy fix to make fit on both cars. Will have a price for the DE/REV-UP items tomorrow. Will have some data re these early next week. Mark

can you post a couple of pics please. Mark

We can use a larger MAF if needed. Mark

I do understand how both systems work , but if you have a stock or tuned map in your STOCK ecu the utec is still trying to tweak around them , I am not trying to knock down Thor at all , just that I understand how the stock system works and cant understand how a tuned stock ECU will cause any more problems than stock tuned ecu. You are not overlaying any multi maps in the UPrev you are tuning the ECU live, no piggy backs or anything. Not even seen Nurrish,s car so I am not tuning the car at all. Nurrish I here to help give me a ring if you need to.

I can return your ecu to stock , but I cant see how this will help.It will still have the same problem I feel. But I would need to be with the tuner to enter the correct figures in the feed back map while it is being tuned. So I cant do this with out a car or being @ the tuning shop. Mark

I could turn the CEL off with just the ECU being sent back , but to do the job properly, I would prefer to tweak the feed back map to the AFR,s that Pete wants to run , this will then stop the CEL coming on.
