    The best thing would be to tell us roughly where you are and we can advise where'd be good for mapping.

    You may find somewhere that can do it locally but its always best to find somewhere with a good recommendation, even if it means travelling a little bit further (within reason).

    As said you can't really run uprated injectors (you'll want the Bosch 395cc ones btw) on the car without being mapped in so that rules out all generic maps like quantum, bluefin etc as you'll never be able to use them.

    You'll need to go somewhere like WGM/Rabbid, Courtenay sport, RS Tuning etc

    Manchester / Stockport. Surely if bluefin/quantum sell stage 1 then they feel no need for uprated, unless of course they don't care what happens to their costumers car

    It’s only stage 1 I wouldn’t even entertain it as not that much bang for your buck , save up get some decent mods first then get injectors and a good reputable map done last you will be a lot happier than a stage 1 , I wouldn’t think injectors would be needed at stage 1 but those generic plug in things do have a bad reputation so be aware could cost you thousands if done wrong

    Its the old story.

    Standard injectors don't have much headroom/free capacity to run extra power. They can be used on mapped cars, and will work fine, provided they are in good condition - i.e they're not clogged/dirty - and if the mapper hasn't choose a fuel ratio that is ultra rich - i.e its spraying more fuel so the injector will max out at earlier at higher rpms and won't be able to deliver the correct amount of fuel at that point.

    I have every faith in bluefins mapping ability but they can't compensate for old/dirty injectors so there no way of knowing if they will be safe on your car, as you will never know how healthy your injectors are.

    This is why its recommended to get uprated ones - a) they're new (so won't be dirty/worn out) and b) they can supply all the fuel you need, even if your mapper chooses some ultra rich bonehead map.

    Other things that affect reliabiltiy of quantum/bluefin maps - people bolting on big exhaust, decats - i.e. things that drastically change the engine charactistics when the map still thinks its trying to run a 100% standard cars.

    Quantum/bluefin and the like are only for mechanically standard cars.

    For manchester/stockport i think you'd want rs tuning in leeds - https://www.rstuning.co.uk

    Rs tuning and RnD motorsport are your nearest that I would recommend.

    Ok I'll prob go rs tuning although I do like York so will probably ring both to get the information required

    Went to RS myself, were great lads, and have phoned them up for advice afterwards too on several occasions and were always happy to help.

    But as said several times throughout this thread, you'd be so much better off hanging on, and going stage 2 or 3, you'll enjoy it much more than stage 1.

    If you are desperate for stage 1 however, I'd personally recommend, along with most others on here, that you get injectors and go for a proper custom dyno tune.

    Those plug in maps are generic - they'll put the same map on every car essentially, and not every car is the same!

    Yeah I think im gonna do both, having spoke to tuners I know roughly how much parts and map gonna be stage 3, I've got half the money and I'm gonna save the other half. Then I will throw the bank at car if the interest to spend so much is still there, shouldnt take too long to save although I will say Vat is ********

    Now bluefin, I can get handset cheap for like £200 reset. I have doubts but the inquisitive side of me just wants to see what it's like then can always reset back to standard map, I spoke on phone and also messaged them and referenced injectors, obviously knowing there stuff they know about p4 etc I just wanted their take on it, they pretty much said should be fine but also suggested hardware, here is their reply

    Hi Arron,



    Thank you for your enquiry.



    Injector duty cycle is most definitely critical on this engine - no less so than other engines of course, however Vauxhall run the injectors at a relatively high duty cycle as stock. We were mindful of this during development and used this as our limiting factor in creating power. The map is designed not to over-stress the injectors, but it will work them harder than stock, as it will all other parts of the engine, because you can't have more power without working harder. That is not to say that instantaneous catastrophic failure will result - the internet is full of such terror stories - but given that it's an acknowledged weak point on these engines, we were mindful of it during development.



    Having said that, you must consider what you expect from this sort of car and engine combination. The car is 8 years old now, and while that's not old by any stretch of the imagination, it's not new either. The Corsa VXR has very well documented issues with cylinder 4 failure even without any modification at all, so anyone who says they can totally avoid such a problem is simply telling a lie. In tuning a car, one will always find the mechanical weak link. If you have a part that is already on its way to failure, then asking it to work harder can cause it to fail more quickly. This is the same as any mechanical device - if the brakes are wearing low and you work them harder on a track, they'll fail more immediately than if you'd just replaced them.



    What I'm getting at is - we're aware of this issue, the map is designed accordingly and it's not true to say that a remap on its own makes the car "a ticking time bomb" - far from it. But you must understand the concepts of mechanical sympathy and tuning when modifying this sort of car. If your car is driven with reasonable mechanical sympathy, is well looked after and properly serviced, I see no problems at all with applying our remap software. If you like, you can speak to our specialist GM Tuning partners at MW Performance (http://www.mwperformance.co.uk/) - they can advise you on appropriate hardware modifications as well as providing our software for your vehicle.



    Best regards,

    Graeme
