    Have a read the ECU thread in our services section mate. Help you make your own decision.

    I would say yes, standalone, to help you get the best out of your cams.

    I can't quote figures, as that will vary from car to car. However the standard ECU has limits, whereas the standalone doesnt, our ECU uses 12x12 table AFR tuning giving much more accurate control over the fueling throughout the rev-range. Will produce a better torque curve, more power and importantly, our ECU can self tune is installed with a wideband sensor. this means the ECU will "learn" the more you drive.

    Also, its more cost effective as if you add more modifications you will need another re-map, and we will do that for a largely reduced cost, and if we fit those other mods, we may well waver the remap charge completely. Whereas with a standard ECU re-map you will be charged the full ammount for another remap.

    Hope this helps mate

    If they are anything other than mild cams - you will benefit/need some sort of adjustment to the ECU.

    If you think you will do further modifications, you'd be best looking at standalone - although the initial cost is more, remaps will be less. If you are not going to do any more to the engine - piggyback management or a remap of the standard ECU would be best. Less initial cost, but if you want to change the settings later it'll cost more.

    As for the advantages of standalone - depends on which kind you go for, and what you need. Traction control? Boost Control? Data logging? etc etc

    to be fair once my car is cammed i dont see any more engine mods occuring, going to wait untill i can afford a car with a blower until i go down the hardcore tuning route, this potential remap will be a one of

    If your not going to do anymore mods once cammed then theres not alot of point spending all that money, you might as just get a remap and be done with it

    although there are many advantages other than less after-mapping costs of a standalone, if your only ever doing cams and never want headwork or TB's then ecu remap might be the way foreward.

    the only thing i think personally is the standard ECU was never meant to be remapped. i'm not saying its a "bad" thing to remap it, just that speaking personally i would rather have standalone or an "aftermarket" ecu system.

    Yeah - never been too convinced by the idea of remapping the standard ECU. At least a piggyback system is eactly that - a piggyback. Remove it and the ECU goes back to normal. Useful if something goes wrong, or you remove all your mods etc

    A piggyback ECU will intercept the signals from the sensor on the engine, and modify those signals and send false reading to the original ECU so it does something different. Something different in a controlled manner, yes. But it's still not in the same league as a standalone.

    Once your ECU remap has finished, you drive away, and perhaps there is something just not 100% the way you like it, the accelleration enrichment algorithm, the fuelling on part throttle, anything you can conceivably think of what do you do?

    The standalone is the only reasonable solution. Unfortunately these can be extremely expensive coming in at 4 figures.

    RCD are developing a plug-n-play solution which replaces the stock ECU, upgrades the narrow band O2 sensor with a wideband and is completely reversible. Uses stock sensors, and will operate permanent closed loop fuelling based on target AFR tables. Your car will *always* compensate the environment you are driving in delivering perfect fuelling on top of a solid safe ignition map.

    It's an adventurous project, and when the demonstrator is rolling, and the dyno graphs are available it will enter the market at a very tempting price.

    We are attempting to revolutionise the tuning market, with easy to install, easy to understand solutions through transparent service. There is nothing we won't explain, no secret 'tricks' no hidden costs. You can enjoy your car and just think about those throttle bodies.

    Oh, and it's party trick? If you want to Turbo/supercharge your car it will just remap to suit, since it has a built in 3-bar map sensor.

    Watch this space!
