Almeida1234 Posted April 11, 2014 Share Posted April 11, 2014 Hey gang I am looking to get this done very soon Car is 2004 GT with berks and invidia system. It also have spacer and hks filter. I am just wondering what sort of difference I be expecting? Also people who has these done what are the pros and cons? Thanks Quote Link to comment Share on other sites More sharing options...
Jared350z Posted April 11, 2014 Share Posted April 11, 2014 All pros as you wont see any gains until you get an uprev as I believe the zed ecu wont recognise the mods and till you tell it. Mine goes in again soon so I can use al the horses Ive put on it. If I am wrong someone tell me HA HA Quote Link to comment Share on other sites More sharing options...
GMballistic Posted April 11, 2014 Share Posted April 11, 2014 Hey gang I am looking to get this done very soon Car is 2004 GT with berks and invidia system. It also have spacer and hks filter. I am just wondering what sort of difference I be expecting? Also people who has these done what are the pros and cons? Thanks Firstly it's not going to turn your Zed into a monster but it will make a noticeable improvement especially in the first few gears and in relation to torque & a linear power curve. Quote below from Horsham Developments. 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. We can reprogram the ECU to have a direct 1:1 relationship between pedal and throttle - not recommended for road use but can be great on track - this feature removes cruise control. 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 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. We can custom map the ECU for a standard engine or almost any modifications. We have access to the following tables: 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. I have very similar mods on my 2003 Zed to your 2004 Zed and mine achieved 293.4bhp@flywheel after it's UpRev at Horsham Developments. The car does feel a lot quicker off the mark now in the first few gears and I have had the 155mph limiter removed so if I ever hit the Autobahn I can really push it now. You can expect a similar power level I'd have thought from your Zed but tbh there are so many factors to consider that it could be more or it could be a lot less (Factors like: current power level/humidity on day of UpRev/engine condition internally/fuel/tyres/condition of parts fitted etc etc). On the same day I had my UpRev an almost identically year/modded Zed achieved around 280bhp@flywheel so it will vary between vehicles. One things for sure though that it will be definitely better after the UpRev. It will be money well spent imo especially if you've already put all those mods on. 1 Quote Link to comment Share on other sites More sharing options...
Grundy Posted April 11, 2014 Share Posted April 11, 2014 Yup, I went from a low 258 to 283, low numbers but big increase Quote Link to comment Share on other sites More sharing options...
Almeida1234 Posted April 12, 2014 Author Share Posted April 12, 2014 I had put the car on the dyno before all the mods and it was 275 bhp so I was chuffed with that. hopefully I should be in low 290 which will be good Thanks Who will be the nearest tuner to me in West Sussex. I don't want to take it some where they don't know how to do up rev tune Quote Link to comment Share on other sites More sharing options...

I don't want to take it some where they don't know how to do up rev tune Not sure on all the UpRev dealer locations but I'd image some like Abbey Motorsport & TDI North are far to distant for you. Closest I can think of is Horsham Developments which is probably an hour & a half or so away from your location. That would be my choice.

Adam rs Posted May 4, 2014 Share Posted May 4, 2014 Get this done if you have berks fitted,had to abort my first dyno run before uprev due to dangerously lean fuelling. 1 Quote Link to comment Share on other sites More sharing options...
