If you are going to use a standalone ecu, just set the reg to stock pressure. The ecu will take care of the fueling requirements of the engine.
Rev limit wise, you can set it as high as you want but it's supposed to be a safety feature, so engine tune and good judgement will play the biggest part. ~7000rpm will likely be your power ceiling, perhaps less/more but you may wish to have a little more headroom to hold a gear longer for an event to save up shifting at awkward moments. The tuner will likely set it as a reasonable level based on performance and you can always increase it if necessary later based on use.
I don't know what the standard injectors from the CGA are rated at but you will need something around the 200cc/min range for your spec. If you find something around 200-250 you will have no issues setting up the Omex on those and have plenty of headroom for any future mods that you may opt for, (you'll be lucky to peak at 60% duty).
If you're going to buy second hand injectors, I'd highly recommend having them cleaned. eBay can be a bit hit and miss and there's nothing worse than poorly performing injectors. These guys do a top job for a reasonable price --> http://www.injectorcleaning.co.uk/ and it's still cheaper than buying new. They sometimes have injectors forsale but lately their stock has been pretty low...
Only people I know who specifically map Omex is Hightech Performance....

I've ordered some QG almera injectors. After reading a couple of threads I've seen some people installing a spacer between the inlet and the manifold. Does this make any more bhp. The regs say that the original throttle body and plenum chamber must be retained unmodified. How does the spacer work and is it worth doing.
Does any know of a supplier off flat top piston other than matthew Humphreys.
I've spent a lot with him are there any other options.
All information is appreciated

Bit of an update on the omex ecu. The car is Runing but There are still lots of small jobs to do.
There was no ignition lights on the dash when i took the old ecu out.
I'm running a Bosch coilpack but the ht leads don't realy fit. This is the frist omex ecu that has put on the coilpack engine
Had to wait for them to do a start up configuration.
Does any know know of any ht leads that might fit its a small pin on the coilpack.

Hi, I'm just wondering what the spec of your car is, I'm looking at building a road rally car so I'm after a few ideas.also where abouts in north wales are you? I'm in deganwy.
