We're almost ready to release the Osiris update for the 370z. Keep an eye on our website for updates, or contact RS-Tuning or Abbey Motorsports. We've also had a price drop recently, so both of our UK tuners are up to date on that also!

We make the Cipher product, it's our proprietary USB to OBDII cable and the software is based on the ConsultII/III from Nissan. Abbey Motorsports and RS-Tuning both sell it.

As an aside. I wouldn't personally recommend racing seats/harnesses to anyone that doesn't have a bare minimum 6 point cage in their car. The factory seats and belts while not the best for race track use, will allow your back to flex under side loads, and will allow the seat/human to bend out of the way if the impact happens to allow something to enter the cabin. A proper race seat and harness holds you in a rigid position and will break your body rather than allowing you to flex out of the way. Also to note, I wouldn't have a cage in the car if I wasn't planning on wearing a helmet, hitting yourself in the head with a large metal tube at 60mph causes your brain to sit on the outside of your skull. So no cage or harness/seat on a car thats driven on the street. If you add a harness bar, and have seat brackets welded into place so you can use this setup, what happens when a car hits you from the side? You're held in place and used as a blockade, you will not fare well. If you're in the stock seat and stock belt you may be severely injured if this happens but you have a good chance of surviving as the parts of the car where the seat and belts are bolted to will flex out of the way and help push you way from the point of impact.

Hey everyone. Just found out about the site. We manufacture tuning software for Nissan and Infiniti vehicles. We don't just support the Z, but we're the best there is for the Z. We currently have two Pro Tuners in the UK. RS-Tuning. Abbey Motorsports. Both well known, with great reputations. And while I know we're knew to the UK customers, the software is the same with the same benefits. So any info you get from other sites rings true to using our software on your cars.

Osiris is a decent EMS. What is out there that we can't support through a shop like RS Tuning? My future plans involve FI, I personally would feel safer with a proper EMS & not a reflash What is the reason for this? Our system has proven time and time again to make more power with higher drivability and reliability than the aftermarket EMS systems. This is 1989 anymore, the factory ECU is not only faster but more reliable. The safety mechanisms built into the code by the OEM take into consideration more about your specific motor than any aftermarket system could, the cost of engineering a VQ specific EMS would be astronomical. Also as far as safety goes, the factory ECU is pre-emptive rather than reactionary. It knows that there is a knock potential and starts to adjust before knock happens. There isn't an aftermarket EMS out there that does that, they are all reactionary. They need knock to happen X number of times in X threshold to then adjust after the fact to reduce knock. Our Pro Tuners world wide recommend our system over aftermarket EMS systems for forced induction. The only real reason to sell the aftermarket EMS for them is because a customer requests it, or they are building 1200+hp cars that aren't designed to be driven on the street. Even Nissan uses our software on their Nismo SCCA and NASA competition vehicles in the USA.

Depends on the year of the car (what version of the VQ motor you have). Forced Induction has it's ups and downs. Mostly downs if you consider the amount spent. The nice thing is that the VQ motor responds well to some basic parts and a good solid tune. The UK cars now have the ability to use our Uprev Osiris software, and we have two Pro Tuners at this point to serve you. Intake and exhaust parts are well known and a basic search on the forum will probably point out far more information than you ever wanted. I always recommend that a customer purchase an exhaust based on the sound because they have to live with it rather than the performance gains. Intake parts are a bit easier, the plenum spacer by any company will net you an increase in power, some are just easier to install. The various intake tubes have different sounds, but not too different so chose them based on cost vs. performance, or if you'd rather have polished aluminum tubes vs. plastic. Cams, headers, etc can be a bit more difficult to choose, and are far more expensive to install. The VQ motor has good head design and responds well to either or both mods. When it comes to Cam choice, it makes a huge difference in the viability of it based on the motor itself. If you have a DE VQ then I personally say it's not worth the money spent. The DE uses small crank bearings, and isn't very reliable when used at anything over stock RPM limits. The Revup VQ is worth the expense of cams + install + tuning. It can handle the higher RPM and aftermarket cams can make power up there with no head work. The big thing with Cams and Headers is you absolutely will need a tune. The stock ecu settings aren't capable of understanding there is better flow, there is no MAF sensor in your exhaust. So in general the cars will run lean with headers or cams. Aftermarket Cams also gain a fair amount with proper adjustment, so some extra dyno tuning on that can net you as much as an additional 20whp above what the cams themselves make. The good thing about these mods, is that if installed properly, and on a motor that is in good condition... With a solid tune the car shouldn't be any less reliable than when it came in. Don't push the RPM limit of the motor, enjoy the huge torque curve, and have fun in the car.

Good looking gains I can't understand half the posts on here though. I think between RS Tuning and Abbey Motorsports, the Z community in the UK is going to do very well. You can check the US forums for more info about our products, or call either of these companies. Even a totally stock car will net reasonable gains, and you should feel a difference in the drivability. As far as the ROM files (aka ECU Part Number) I'm not sure if the dealerships there will give out the info like they do in America. We generally have the customer contact the Dealership Parts department for the ECU Part number. We have most the US Spec ROMs patched, but not many of the Euro Spec ROMs. If we don't have it patched you can either send the ECU or take the car to either of our Pro Tuners. It takes them roughly 30 minutes to get the ROM. Once they have it, they e-mail it to us, it gets added to the queue and when it's patched we'll get it back to them so they can tune it. Average turn around time for a ROM patch is 3-4 weeks.
