Greekman, have a look at this thread; viewtopic.php?f=25&t=27646

looks like our man did very very well; Have a look at the results; http://www.tsl-timing.com/?loc=club&sea ... ntid=93932 Formula Nippon series , he made very good progress on his lap times , qualified on a 57 got down to 55 in the races. Well done

If you could have a thermal spacer to go between the lower manifold and cylinder head that might help, will stop heat from the motor getting to the inlet set up , but a thermal manifold spacer I dont think will do a lot. Manifold spacer only really helps freeing up the flow to the front 2 cylinders. Mark

Well just been out on the road with a car with a NON std air filter kit fitted , def runs higher than std air box car, but 1 thing the heat soak is real bad, the temp sensor drops quickly but the inlet plenum it self stays warm for ages. In my opinon the STD airbox works very well , will try a car very soon with HKS filters in a STD airbox , but I feel save your money with regards an air filter set up and leave your car STD.

Good thread, good some one has bit the bullet and having a go at racing a Zed. It would be good to read what spec your car is. Give me a ring "Mr Lizard" I am sure I can help you out , mayb a Uprev remap or something like that. Good Luck for the race,s on Sunday. Mark

We have a Up-Rev reflash ready for the HR engined motors , these will cost £345-00 inc vat , includes before and after dyno run. This is for a STD car , we tune the fuel maps, cam duration and remap the throttle opening. We find around 5/8 bhp and 10/15 torque and the car will be a little more economical. We can also provide a valet map within the reflash price. £345-00 inc vat now includes 1 hour dyno time to trim the map to your car. Any questions fire away. Early cars being worked on very soon. Mark

No didnt do any logging on the road , as I find it very hard to get the same conditions. But both runs where done in the controlled enviroment in the dyno room, With the STD air box fitted we was seeing inlet temps around 24/25 deg C with the bonnet down , with the Nismo filter kit with the bonnet shut was running around 38/40 deg C and with the Bonnet up it reduced the temp by 3/4 degree,s.

Map switching is only on Gen 2 ECU,s onwards I am afraid for UK cars. All cars with inlet/exhaust variable cam timing have Gen 2 ECU,s Mark

viewtopic.php?f=25&t=27646 On Andy car when logging ecu inputs we saw 20 degree C difference inlet charge temperature between running the STD air boxes and the Nismo filter kit , even with running the bonnet up there was still a great difference in temperautre between the 2 set up,s. I managed to tweak the map to regain the lost BHP when using the Nismo filters mostly by tweaking the fuel map and cam set up , but if we could keep the inlet temps as low a sthe STD car I would imagime we may well see a few bhp gained , but in my eyes your never keep these filters cold enough when they are bolted in the engine bay. We may well try STD air box fitted with HKS filters to see if this makes any difference. Re Up rev tuning; Reflash is a before and after dyno run. No extra dyno time included . If your car is alot different to what we have a reflash for , you will definitley need a few hours dyno time , this is charged at £85-00 + vat (£97-75 inc vat) We are slowly working through the model range , 1st with stock cars. We will never find massive amounts of BHP from these very well stock tuned cars , but we can nibble at the maps , and help with smoothing the BHP and torque curves out gain a few bhp/torque here and there . If you have other items fitted i.e exhaust, high flow cats or test pipes , plenum spacer and a good set of filters they will give a few more BHP and torque but again not massive amounts. hope this helps.

JDM car being converted to have Cruise control , is a major job, ECU change , steering wheel just off of the top of my head. On Andy car when logging ecu inputs we saw 20 degree C difference inlet charge temperature between running the STD air boxes and the Nismo filter kit , even with running the bonnet up there was still a great difference in temperautre between the 2 set up,s.

Mods, can we sort out the parts of the thread that is relevant to the HR remap , I then when I find time will have a read throu and answer some questions that have been thrown up. Been doing some working out on prices I think the reflashes will be around £345-00 inc vat , this includes a before and after dyno run. This isnt cast in stone yet but a fair price. Extra time on the dyno will be charged at £97-75 inc vat per hour on the dyno ( VAT @ 15%) say if you car needs a little more work as it has a few different mods than what the reflash has been tuned for. Mark

Do you southern boys want a dyno day down our way?

closer one than that, try PJ motorsport. Speak to Paul, tell him I put you in touch. www.pjmotorsportltd.co.uk/preview.htm

Comparing dyno,s will always open a can of worms, even more when you start adding run down BHP to wheel figures to get a "flywheel" figure. Running in different gears will provide a slightly different BHP figure due to the loss in a higher numeric ratio while running in 3rd. Running longe ror shorter runs can give different figures so many variables. Also running the cars loose as in not tied down will give different figures. As the RS tuning man (sorry dont know your name) our figures will be different again as we read at the hubs. Dyno days always end of with people asking questions, before and after on the same dyno under the same conditions is the only way to get a good reading.

yes got the PM,s . to busy till October to start looking at doing the re flash maps , will be in contact with everyone when I will start on the project.

yeah agree , we have had 10 of the same cars on the dyno, there was a 15bhp difference between these cars. Point is all cars are different.

all cars are always different a car with 10,000 miles on the clock will give more bhp than a car with 80,000 miles. So we cant give definite quotes, but your def get an improvement. Have a look at the RS tuning thread , you get an idea of the gains from Up Rev remap ( reflash).

Gains; should give a better spread of mid range torque , increase of top end BHP , better throttle response and a few hundred more rpm at the top end. Mark

thanks lads/girls. Looks like I will be onto mapping cars late september/early october, so will be in touch with people very soon. Been doing some working out on prices I think the reflashes will be around £345-00 inc vat , this includes a before and after dyno run. This isnt cast in stone yet but a fair price. Extra time on the dyno will be charged at £97-75 inc vat per hour on the dyno ( VAT @ 15%) say if you car needs a little more work as it has a few different mods than what the reflash has been tuned for. can I have some feed back on this please. Mark

Alex,s cracked we think due to the boost being pushed through it, but they are also not that well made , welding of the seams isnt deep enough . But we have also have seen them cracked on N/A cars this was due to vibration.

Cosworth Mnaifold is only good if you want to go over 8000rpm in N/A tune F/I never heard anything yet if they work or not with F/I, Kinetix,s well they make a good door stop.....

no sorry thats only for the girls.....LOL

sounds good , where you based , really need the car for 2 days , can offer a courtesy car to use while we have yours. Mark

is that a 2 x variable cam car or an 1 x variable cam car? Mark

Got as above Haltech Plainum ECU for a 350Z for sale , used on my own car , but as we are now Uprev Dealers it is not used any more. Very good piece of equipment. I would like £500-00 for it if possible , any takers? Mark
