wilo Posted September 12, 2016 Share Posted September 12, 2016 hi guys i have found a company to do the servicing and plenum spacer on my 04 DE . the company also remap but use something called viezu . is this way of mapping as good as the nissan uprev ? im looking for increased rev range and more low-midrange bhp/torque . any advice appreciated as im kinda new to the mapping thing Quote Link to comment Share on other sites More sharing options...
GMballistic Posted September 12, 2016 Share Posted September 12, 2016 the company also remap but use something called viezu . is this way of mapping as good as the nissan uprev ? Honestly never heard of "Viezu" and considering I've been in to modifying cars since the mid 90's I'd say that was a bad thing. I mean I definitely don't know everything but to never have heard of a tuning company who claim to deal with so many vehicles is strange imo. I did Google them to read up a little but from what I can tell looking at what they do it seems more like a generic map made for each car model rather than a tailored/custom map done specifically for each car taking into account the different mods each person may add. Personally for the 350 I'd stick to the UpRev for what you want it to do (imho). Quote Link to comment Share on other sites More sharing options...

coldel Posted September 12, 2016 Share Posted September 12, 2016 Im a bit of a numpty when it comes to spanners, I managed to put the plenum spacer in myself with a basic tool kit. Its quite do-able for the amateur and I am sure there are guides online (google motordyne) if you really want to shave a few quid off the costs.

coldel Posted September 12, 2016 Share Posted September 12, 2016 I actually bought a torque wrench for this exact purpose, that was about 5 years ago now, used it loads since so got my moneys worth. If you ask kindly, you might be closeby to another member on here who has done it before who might help out for beer tokens or the like - people on here tend to be good like that Quote Link to comment Share on other sites More sharing options...
GMballistic Posted September 12, 2016 Share Posted September 12, 2016 TDi North are at a guess 2 hrs away from you wilo (very experienced guys): http://www.tdi-north.com/services/dyno-tuning-services Heard a few people mentioning RS Tuning in Leeds which will be closer but no idea if they do UpRev as I can't see it on their site: http://www.rstuning.co.uk/ Worth a ring though.

wilo Posted September 12, 2016 Author Share Posted September 12, 2016 i am also interested to know if any one can explain...... why is my 2004 DE limited to a rev range of 6200 but the newer revup engines have a rev range of 7200. im sure nissan has a reason for this ? would a uprev remap inc increasing rev range possibly have a negative consequence on my engine? or is simply to do with the restricted air in the standard plenum set up why its 6200....interested on thoughts or facts Quote Link to comment Share on other sites More sharing options...
Rock_Steady Posted September 13, 2016 Share Posted September 13, 2016 6200 rpm? Are you sure? Or is that just when the red limiter light blinks on? because you can adjust when the red limiter light can come on. I had my 05 DE re-mapped @ Abbey and it now revs to 7100 rpm. Not sure what revving the bollocks off it will do eventually but to be honest i never rev it that high. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 13, 2016 Share Posted September 13, 2016 One thing to remember aside from quality of the software involved...is the map is only as good as the person writing it! Quote Link to comment Share on other sites More sharing options...

Not sure what revving the bollocks off it will do eventually but to be honest i never rev it that high. mmm i will double check as yes i do have this annoying red blinking light. tbh i think the problem is that I came from a high reving toyota engine previously that begged to be revved and loved it and feel the zed a little restrictive in regards to its range. also my concern is if i do get the revup remap which increases rev range ...will the enging produce more bhp/torque beyond its standard rev range ...or does it simply move the restriction further away ?

coldel Posted September 13, 2016 Share Posted September 13, 2016 The blinking light is the shift change light, this can be changed to different levels (its in the handbook) Yes the engine characteristics are different, but its a V6, its likely to rev differently although not likely to be any quicker across the ground. Its just the way engines are I am afraid, I would not go spending big money on parts and remap just to rev it a bit more. The flip does apply, many people driving these sorts of cars find the high revving Hondas shouty and lacking punch where you have to rev the pants off them to get them to do anything exciting - it really comes down to what you like.

evest Posted September 13, 2016 Share Posted September 13, 2016 The earlier engines are potentially a little bit gruntier lower down whereas the later engines provided more horsepower and torque across the range. The HR was nearly a completely new engine so different redline part of the overall design. Your plenum spacer and other mods will provide more power but only with the benefit of a custom remap to tune the engine. Plenty of dyno evidence of the improvements available on here. I doubt it's a good idea to increase the DE rev range by too much as it wasn't designed for it and how often do you drive in the 6000-7000 range on the road? IMO best to maximise potential in the existing rev range to ensure you don't knacker your engine. Good luck! Quote Link to comment Share on other sites More sharing options...

Good luck! cheers evest ...thats the info iv been looking for . i dont think i worded it correctly but now you've explained i see that yes the uprev is worth doing ...although increasing rev range might not be such a good idea especially as my girl is quite a high milage engine . i hope i get some choices with the remap as tbh throttle responce and midrange is where it needs improving imo. 1 Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 13, 2016 Share Posted September 13, 2016 Pointless trying to increase the rev range of the VQ, one reason is the valve train doesn't like it, its a week point, and secondly in order to benefit from doing so you will need to spend shite loads of money you can gain perhaps 25 bhp and i little more torque with a remap and the right supporting mods, but you will never notice a big difference, just better driveability.

evest Posted September 13, 2016 Share Posted September 13, 2016 You may well find more power available with the original airbox fitted along with a decent filter. I've gone back to the airbox - sure it's not as bling under the bonnet but at least has good heat shielding. Quote Link to comment Share on other sites More sharing options...

Not placebo at all, but you can easily spend £2000 on an exhaust, HFCs, spacer, remap and then find you get 5%-10% more power and a slight increase in rev range - it wont ever bring you back to the free revving Honda space, the dynamics just wont and cannot change on the V6 in that way...

Rock_Steady Posted September 14, 2016 Share Posted September 14, 2016 i was surprised to find out that all the mods i had done to my Zed prior to it being mapped, gave me an extra 4 bhp over what it says it is on paper (276) O.k, i concede that 4 bhp is nothing to get the DJ and beers out for but, it shows it can make a difference and that it's not just placebo.

GreenLandy Posted September 14, 2016 Share Posted September 14, 2016 My old DE had HKS filter (standard panel, nothing fancy as they're worse), plenum spacer, decats, stillen y pipe and scorpion back box and a revup got it to just under 300bhp Quote Link to comment Share on other sites More sharing options...
