Found this from the zclub forums:

http://www.abbeymotorsport.co.uk/site_flash/index3.html

The Nissan VQ engine equipped Z cars uses a very sophisticated engine management system , even fitting items like free flowing exhaust and air filter will not give any return in extra brake horsepower and torque.

The ECU has the built in ability to self tune both the fueling and ignition and the car uses a fly by wire throttle system so this also control the bhp/torque in the lower gears by not allowing the throttle to be opened 100% in the 3 lower gears, 1st gear 65%, 2nd gear 70%, 3rd gear 80%.

If you say fit an exhaust and air filter kit, the car when running monitors

The air fuel ratio before the catalytic converters, if the ECU sees a difference to what the car was tuned to as standard it will tune itself back to the parameters within the ECU map. If the ECU keeps seeing a difference in the AFR reading it will then put on a Check Engine Light (CEL) this will stay illuminated until the problem has been cured and the CEL turned off with OBD II diagnostic tool.

The excellent UPREV system allows Abbey as a Pro UPREV tuner to reprogram the Stock ECU to allow for free flowing equipment to be fitted to the car, we can adjust the map when the car is in closed loop

to give the correct AFR figures for maximum safe BHP after freeing up the breathing on the car. We can also tune the ignition map to give a increase in performance, the ECU again uses a sophisticated system where as it slow feeds the ignition timing whilst listening to the cars detonation sensor until it using the figure that is in the low detonation map, this is why when tuning VQ motors the car needs 5/6 pulls on the dyno to get a reliable figure. Any noise read on the detonation sensor the car quickly reverts to a high detonate map which normal has 4 to 5 degrees of timing removed, it will then slow start returning ignition timing until it is back to the preset timing with the map.

We can also adjust cam angles with the UPREV system as well as changing injector sizing and have the ability to fit a larger capacity air flow meter for running above 400-wheel bhp. This helps when running the with Forced Induction, which the VQ response very well to. Running up to 400-axle bhp the stock internals are safe, to run over this BHP you need to rebuild the motor with up rated parts.

Hmmm...gonna drop them an email and see if they can do anything with the VQ25DET...being in the UK I'm sure they have the NM35's there so there may be hope!

guys - got a response from Mark @ Abbeymotorsports in the UK:

Jethro, As your car has a VQ I think we can help you , but 1st I need all the chassis numbers for the cars fitted with the VQ so I can work out how many different ECU,s are available. This will then allow me to work out if I need all the ECU's fitted to the cars to be sent to me to allow me to dump the ECU,s RAM.Are there Auto and manual cars made? Hopefully there will only be 2 ECU's one with cruise and 1 without cruise? If we can work this out I am sure I can sort mostly of your problem's out. But to be 100% sure I will definitely need an ECU sent over to me in the UK. let me know chassis Numbers and spec ASAP thanks

It sounds like he knows nothing about Stagea's or the VQ25det...

I would prefer a Japanese ecu reflash as they have had many more years to refine theirs, unless this is a user programmable option? Uprev is a US company making tuning solutions for 350z, theirs are OBD2 compliant, ours aren't so completely different ecu's.

there is 15 different ECU numbers for your type of car which is a pain as we may need to dump everyone's ECU to allow the patch to be built to allow us to tune your cars. We need the ROM from every different part numbered ECU. How many people are interested can you get everyones FULL CHASSIS NUMBER please. The ECU's will need to be with us for 1 full day before we ship them back to you In Australia IF we can help you out.

Sigh...maybe your right Scott....looks like GZONE it is...>_<

Our cars are OBD2 compliant (Nissan's Consult 2 works fine with our cars)... just an odd protocol for some reason >_<

Yeah G Zone seems to be the tried and true method at the moment. Come on Ryan hook in and get it over there so we can check out the quality of their work! haha

Don't get me wrong, I have been advocating the Gzone as the remap to get for a long time now, but really, tried and true?

This.

Gzone would be good, but its still not ideal because it cant be tweaked locally on a dyno for your car. If the UPREV solution can play nice with our ECUs it would be a huge win. Fingers crossed. Great work ironpaw :thumbsup:

The issue is Mark wants a whole bunch of chassis numbers to check and thinks there's "15 different' ECU's for our car.

I've given him my Chassis number and that doesn't seem to help. Can I confirm that "NM35305300" sounds right? I told him this and he goes "I need the whole chassis number..."

Hopefully I can convince him to just use a spare ECU that's floating around here and work off that. I don't see why he needs ALL our ECU's to find a solution...

The ECUs were revised from waht I've seen other people discuss on here; I dont know any specifics (I doubt anyone does) but I wouldnt be surprised if they tweaked them a few times. Having said that, I'm not sure about 15 but there could be a few... If hes got some info on M35s in general that may well include 2wd, and awd variants, auto, manual, as well as ARX and Axis of the Series 1 and Series 2 variants. No idea on chassis numbers off the top of my head unfortunately :(

What I was getting at was G Zone will actually do the re-map unlike evryone else we have approached and we know they can do it.

Aaah, you were referencing G-Zone as a company, not a product. I see.

G-Zone, Ks, Mines, Impul will all do remaps if you ship your ECU to them.

Mines and Impul will even sell you a remapped ECU if you don't want to ship one over (or just want an extra, just in case).

Using FAST with your VIN (which is what you supplied him), I grabbed and PM'd your "Model reference" if that is what he is after.

If he still wants your "chassis number" I suggest you explain to him that the although Stagea is a JDM only model, there are a few examples in the UK... although I always thought that UpRev were a US company.

Anyreason these won't work for our cars?

If I read the old discussions properly though, Mines wouldn't remove the throttle restriction.

I figure we're not going to get a flash that does everything we want, but a flash that removes the speed limiter and throttle restriction and gives us 80-90% of what we want is fine with me. And when I want that remaining 10-20%, I can get an emanage knowing that the two main areas it can't fix are sorted from the flash.

Ask Scott when you see him next how well it worked in that regard.

Mines completely remap the entire throttle map... does that mean they remove the restriction? Buggered if I know.

I asked them directly if they remove the restriction below 3000rpm and they replied "we do not", but they did state that they do remap the entire throttle map up to their normal 7100rpm (they will go higher, but issue a warning of "please consider engine safety").

I think your plan of the Gzone + emanage is almost as good as it gets.

Hopefully we can get from G Zone exactly what they are willing to do so there's no confusion. I just want the performance I'm missing better fuel economy when I'm toodling around taking it easy. I don't think that's too much to ask as we know we aren't getting full throttle and we also know that the japs love to tune cars super rich from the factory.

Yeah I read that thread and whilst it doesn't remove the restriction since its ECU limited, it does make it more responsive doesn't it?

Scott tried it? Guess it didn't go well...:wacko:
