RS8055 Posted January 23, 2015 Share Posted January 23, 2015 Hi guys, I am not very knowledgable with regards to the gains (if any) I may get from doing this, but I thought I'd ask for opinions. I bought my 350Z (2004) DE completely standard. Since then, due to the strict Luxembourg laws on modifications, I have only managed to fit the following: - Invidia Gemini true dual cat-back system - Lightweight Flywheel - New clutch I was thinking of getting a remap done on the car, but wanted to know the following: - Is it worth doing? - If so, does anyone know roughly what kind of gains I am likely to get from the remap (if any)? - Where could I get this done and for what kind of price? I'll be driving over to the UK next month for a week. Cheers, Ryan Quote Link to comment Share on other sites More sharing options...
370Ad Posted January 23, 2015 Share Posted January 23, 2015 http://www.h-dev.co....ge=350z_mapping 350Z and 370Z remapping Horsham Developments is an UpRev authorised Pro Tuner. The UpRev engine management software allows us to fully remap the standard 350Z and 370Z ECU. We have remapped (aka chip tuned) many 350Zs with great results. You can expect: Better throttle response - the standard ECU reduces throttle response in the lower gears. By tuning the throttle pedal to throttle plate map we can make the car feel more lively. Also, fuel and ignition timing map optimisation is carried out leading to further improvements. More power and more torque - by optimising the various fuelling and ignition timing maps we get the most power and torque from your car Better fuel economy - some customers report better fuel economy after their remap. Obviously this varies quite a bit depending on driving style. Speed and rev limits - we can alter speed and rev limits Removal of check engine light if running with de-cat pipes Multi maps - some cars (dependent on ECU) can have up to 5 ignition, fuel and rev / speed limit maps. This allows, for example, a valet map or a map for high octane fuel We get good gains from completely standard cars and make the most of cars fitted with aftermarket parts. Check out our engine upgrade packages here. Take a look in our Facebook gallery for examples and graphs showing our 350Z and 370Z ECU remapping. We can custom map the ECU for a standard engine or almost any modifications. We have access to the following tables: 350Z Mapping Idle RPM Speed Limiter Electronic Throttle Control to achieve Wide Open Throttle at all speeds Rev Limiter DTC disable AFR Targets Fuel Compensation Ignition Timing Advance Cam Phasing for equipped vehicles MAF transfer function Cranking Enrichment and Ignition Advance Injector Latency K Fuel Multiplier Intake Temp Calculated Load vs. RPM Minimum Effective Injector Pulse Width The UpRev software is a licenced based system. Once you have bought the software licence we can remap your car as many times as required. A 350Z or 370Z remap for a normally aspirated car is £399.99 inc VAT, dyno time and Uprev license. If you already have an Uprev license on your ECU mapping is done at a reduced price. Mapping forced induction cars is more time consuming and therefore a little more expensive - ask for a quote Uprev also allows us to bypass the immobilser on supported cars. The 350Z, 350GT and G35 Skyline can all suffer from NATS immobiliser failure. Often Nissan cannot help, especially on Japanese imports. The error codes are often P1610 and/or P1614. More info here.

RS8055 Posted January 23, 2015 Author Share Posted January 23, 2015 That sounds great. Sorry if I wasn't clear. Specifically bhp/torque gains (rough estimate) if possible please? Cheers! Quote Link to comment Share on other sites More sharing options...
brillomaster Posted January 23, 2015 Share Posted January 23, 2015 if the only mod you've done is an exhaust, then not a lot in terms of absolute numbers - maybe 15bhp? add a plenum spacer and high flow cats for better gains. but all the advocates of an uprev will tell you its not about absolute power gained, but the way the car feels when you drive it... personally, I don't buy into it myself, im happy with just an exhaust. 1 Quote Link to comment Share on other sites More sharing options...
ZEUS Posted January 23, 2015 Share Posted January 23, 2015 (edited) Very little gains. Personally I'd spend the money elsewhere and not waste it on a remap . I had it done and it felt no different even with the supporting mods . Edited January 23, 2015 by ZEUS Quote Link to comment Share on other sites More sharing options...
mrt Posted January 23, 2015 Share Posted January 23, 2015 I went the usual route and fitted High flow cats,dual exhaust,etc.and had my car uprev remapped at TDI North. Only difference I,ve found is that the car revs harder to achieve the same speeds per gear. No noticeable accelaration improvement and fuel usage is poorer. For me, not worth the cost but the exhaust is ace. BHP went from 313 to 333. Good luck Quote Link to comment Share on other sites More sharing options...
GMballistic Posted January 23, 2015 Share Posted January 23, 2015 Hello Ryan. I'm not going to recommend doing it or not doing it but all I'm going to do is say have a good read through the "dyno results" thread and make up your own mind. Link: http://www.350z-uk.com/topic/23450-dyno-results-info-thread/ Personally I was happy with my car after my first UpRev & I did feel it made a difference to the way it drove but that is purely how I felt about it.

370Ad Posted January 23, 2015 Share Posted January 23, 2015 Up Rev was great on my old DE. Gained 10% and fuel economy went up 2 MPG. Paid for itself over the two years. Quote Link to comment Share on other sites More sharing options...
RS8055 Posted January 23, 2015 Author Share Posted January 23, 2015 Thanks for all the helpful info and responses lads. Will have to have a serious think about it before I come over in a month Quote Link to comment Share on other sites More sharing options...
hensh65 Posted January 23, 2015 Share Posted January 23, 2015 Some people are happy and some are not with their map. Some people haven't even managed to get to the standard power after the map due to the car lossing so much power with age. (also assuming it had 280 when new) If you have a place near you who can do it then I would, it was just too much of a nightmare for people in Scotland to get it done with the closest person about 5 hours drive away, otherwise I would have got it done on mine.

Pritchard Posted January 28, 2015 Share Posted January 28, 2015 (edited) Check out page 2 of my before and after dyno runs during my remap. http://www.350z-uk.c...ey/page__st__20 23hp more, 24lb/ft more from (on the day) plenum, '06 airbox, ecu and sports cats. i got to be honest, i have had other remaps before but i didnt notice any difference in the drive after for the Z. other than being louder i didnt notice any difference in the pull at all. also my MPG has never recovered (See page 3 of that thread.) its 100 vs 1, i seem to be the only person with negative mpg after. at least to this degree. maybe im the fool. but, if your after solid proof in the way of numbers, the above thread will show you numbers. if you want to know ''how it feels'', then everyone will describe it differently in their own words.

wmr1980 Posted February 11, 2015 Share Posted February 11, 2015 I personally feel it's made the car more responsive to the throttle and having that extra bit of torque does sharpen it up a little. You're not going to make a huge amount of power, but it just helps to get the most out of your mods and also just lets the car behave the way it should have been out of the factory.

S14DST Posted February 12, 2015 Share Posted February 12, 2015 (edited) So to remap stock ECU I need to get some UpRev license? I can't just connect via OBD2 and do some minor changes? My biggest concern at the moment is that, throttle in 1st:2nd and 3rd gear are limited by the stock map! But those gears are the ones I will use on track to drift... There is no DIY right? Oh and I have an european LHD model Edited February 12, 2015 by S14DST Quote Link to comment Share on other sites More sharing options...

S14DST Posted February 12, 2015 Share Posted February 12, 2015 Thanks for reply octet But to my understanding for example d1 spec throttle controller won't solve the throttle opening limits in lower gears right? Quote Link to comment Share on other sites More sharing options...
brillomaster Posted February 12, 2015 Share Posted February 12, 2015 the car isn't throttle or power limited in the first three gears - it just has lazy throttle mapping. The throttle controller removes the laziness in throttle response, so the throttle opens earlier for a given pedal movement. Quote Link to comment Share on other sites More sharing options...
Pritchard Posted February 12, 2015 Share Posted February 12, 2015 Instead of translating 'Restricted' into ''less Power'', translate it to 'higher Latency' , or 'Lag Time' The power to the road does not change. Quote Link to comment Share on other sites More sharing options...

So it's just not as responsive as it can be pedal wise?

Grundy Posted February 12, 2015 Share Posted February 12, 2015 Pretty sure 1st 2nd 3rd are restricted. Something like 70/80/90% you're not getting the full power band out of the them. #teamtarmac Quote Link to comment Share on other sites More sharing options...
brillomaster Posted February 12, 2015 Share Posted February 12, 2015 where are you getting that from? I can find plenty of evidence that the ecu restricts throttle timings, but nothing about an actual decrease in power... Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted February 12, 2015 Share Posted February 12, 2015 LOL! everyone has their own interpretation of just how the ECU handles throttle opening control. Quote Link to comment Share on other sites More sharing options...

Sorry for such simple questions, but I never had to deal with zeds, only now for a few months of owning it Check for posts made by Abbey motorsports. Mark has made mention many times abou thow it works. a Z doesnt have 276bhp in 4>6th gear, bit 220-bhp(-20%) in 1>3rd :lol: I had a VVC engine previously that had the same 'delay' built into the factory tune. there was a great graph for it, i'll see if i can dig it out. think of it this way: Our throttle is drive-by-wire, not cable. Slam your foot to the floor from 0% open throttle (closed) to 100% open throttle (Fully Open) might take 0.3secs. however the ECU actually controlls throttle position, based on the ecu tune, load, position of foot etc. in that same foot movement, the ECU might reach Fully Open in 0.4secs The numbers are made up, just to create an example. but the throttle will be opened 100%.(if it wasnt, you wouldnt make maximum power) it just takes longer to open *IN COMPARISION* to your foot strike.

NeilMH Posted February 12, 2015 Share Posted February 12, 2015 ^That's a good description. The other analogy that I think Mark uses is of the lazy throttle being like an elastic band effect. 1 Quote Link to comment Share on other sites More sharing options...

Oh and I have an european LHD model no trouble to supply Uprev cable and a good base to start with. As long as the car has wide bands fitted I can E tune the car via datalogging. Although some people say they cant feel a difference a lot of people are very happy after tuning with Uprev.

Something like 70/80/90% you're not getting the full power band out of the them. #teamtarmac no we thought it was restricted int he lower 3 gears but it is the response that is different in the lower 3 gears , as I say the elastic throttle cable is more stretchy in the lower 3 gears than in the upper 3 gears.
