    What's the deal with these??

    With any other car I've mapped a file is simply uploaded to over ride the factory map. With these it appears they are a totally new unit, should I look at these if I'm planning cams, manifold etc?? Looking to hit 150bhp and possibly a rebuild

    If you're just doing cams etc and not looking to modify further, then there's no real need for standalone ecu

    Cheers, so are they mainly for cars running throttle bodies or running boost?

    Can be for any car, but for the probe and mapping on top.. If you don't intend to go further later on, it's pointless getting one really

    They are a brilliant bit of kit, but you would be better off spending the money on something else (sorry to Andy for talking him out of a sale)

    I've just had one built for my vtr turbo very good quality build! And he certainly knows his stuff like Blackie said no point unless ur running bodes or a turbo etc

    I agree - in fact I'd say that in my VERY humble opinion, I'd go with a ported and worked on cylinder head before I go with the throttle bodies.

    I'd go 'proper' cold air K&N type cold feed intake, ADZVTR has the BEST I ever saw!
    Then I'd get the 4-1 exhaust manifold and straight through exhaust

    Up to now you don't need a remap.

    Next I'd get the cylinder head worked on, just a nice skim and rebuild with some work done to the exhaust ports, don't bother with the inlet side, and fit back on with cams (708's or the new replacement grind), and get it remapped then. You'll want to go for a 3.5bar reg off a VTR or some Clio 182 injectors (cleaned and flowed at injectortune prior to mapping!!) then get your mapping done.

    If after that you want more power, I'd go for pistons, bigger cams again like the PH4, and throttle bodies

    I found my predator to be very very useful.
    There may not be a need for stand alone but with cams you do need a remap.

    I had no intention of doing throttle bodies for my car but because i had a Predator it made it quite easy. The results (on my ported polished ph3 cammed engine) were really good and it only cost £150 to go from being cammed with a standard inlet on ph3's to being on throttle bodies.

    I cut a standard inlet (lower part) and connected it using silicone hose to GXSR 1000 throttle bodies(£100 delivered, Ebay- i may get some money back for the GSXR injectors). (£30, Hoses and jubilee clips). The outside edges to the standard manifold part I used tiger seal, then clear more flexible sealant around the inside of the hose. the tiger seal was more structural and left to set first, the clear sealant was to ensure there were no leaks.

    I did some testing to work out which way the GSXR throttle position sensor went and wired that in.
    I sent one vacuum tube to the pressure regulator vacuum and another to the brake servo.

    Where the injectors were taken out of the bike bodies I blocked them up using 1p pieces.

    Throttle cable I bent round and pushed down from bulk head and then comes up towards the underneath of the bike bodies. Then the other end adjusted for length at the pedal end but keeping the cable whole.

    I got two pieces of aluminium strip and fixed them to the head and to the bodies- the setup was fixed very solid.

    Mapping was done over the net by Andy which included throttle position being set, so then it was totally working off the GSXR position sensor.
    I was using the standard bottom part of the inlet which enabled me to use the standard injectors.

    Results were really good.
    Things that could be done better:
    My inlet manifold could be smooth- so I am getting one developed, should be ready in Feb

    Throttle cable could have been connected better, it took a bit of fiddling about to stop it jumping out/ getting stuck.

    If I had cut the hose differently or used a proper inlet then there would have been more space for longer smoother inlet and result in more torque.

    i have started a new thread as this could drag off topic- apologies to original poster.. my point was Predator- versatile... look how it made this possible!

    No probs, I've found out what I need to know
