omex 600

12th June 2010, 18:00

does the omex 600 ecu work on any car as long as the loom is made up correctly?? can it be remapped and set up to work with cams and throttle bodies etc ??

12th June 2010, 18:24

any car- no

most cars with throttle cable and no fancy electrics.

they work well with modified engines with cams/throttle bodies/turbo etc.

edit: the 600series is also limited to X amount of pistons and Y revs and also limited number of injectors.

it would work on most "popular cars" tho wudnt it?? eg saxos, 206's, cars like that?

12th June 2010, 21:27

if the engine in the car had an electronic throttle it would need to be swapped out for a manual one but other than that yes pretty much, it does have its limitations though

12th June 2010, 21:35

would it work in a mk2 vtr with carbs and cams?

12th June 2010, 21:39

carbs? no, you dont have an ecu.

12th June 2010, 21:40

i fort you could use an aftermarket ecu to control the ignition?

12th June 2010, 21:44

yeah you could if you wanted to, but theres no point spending the cash on a full blown standalone just to do half the work. Something like megajolt would be a better option

12th June 2010, 21:46

how much are they??

12th June 2010, 22:04

Yeah, just buy a standalone ignition management system

12th June 2010, 22:26

Omex 200 is an ignition only. Im running an Omex 600 on standard inlet 16v. Runs well but inlet is not suited to it tbh.

13th June 2010, 11:06

have you got it yet or just thinking --and what is the end spec of the project going to be

13th June 2010, 15:17

well im wanting to bike carb it but as with so many things there is lots of different opinions, hope fully at the end the engine will b cammed, and be running on bike carbs

14th June 2010, 21:07

omex 600 is an old ecu --current one is omex610 is it not ?,thats why i ask if you have it yet.
you do not want carbs --t/bodies yes be they bike ones or car ones --but not carbs

no john, omex 500 is the old one. the omex 600 is current as far as im aware, then the omex 710 is their high end model.

Im sure the 600 only runs upto a 4 cylinder/4 injector system from memory?!

Last I checked, a saxo vtr had 4 cylinders and 4 injectors

As others have said - if you're planning on getting carbs (which is a waste of time tbh, get TB's if you're going to change and are thinking of the Omex) then just get a standalone ignition only setup. Think someone already suggested megajolt for example.

omex600 limits you to 4 injectors tho which wouldnt be suitable if you wanted to run an 8 injector setup for itbs

weather or not its worth having the extra 4 injectors depends entirely on your setup, location of injectors, using wild cams and so forth

although most of the 8v bodied pugs on rr use standard injection position for fuel delivery as apose to 'upstream' in the setup. all depends how complicated you want to make it and what results your after at the end

17th June 2010, 10:22

The OP isn't getting TB's - he's getting carbs. so the 600 Omex is royally wasted.

I can't think of a single situation in which you'd want 8 injectors on a non-boosted saxo.

4 injectors, each flowing 600+cc is enough for 350bhp...

17th June 2010, 10:22

you might be able to to use 8 injectors and set it up as semi sequential?

why would he want 600cc injectors xactly? hes never going to make 350 on carbs the way i understand it is using 8 injectors gives better low end grunt and better mix of fuel at wide open throttle imo 2sets off smaller cc injector are BETTER then one set off injectors to cover maximum power

QUOTE TAKEN FROM SANDY309

Quote:

for example if he anticipatedneeding 250cc injectors to cover the maximum power, two sets of 150cc will provide much better mixing and resolution at low load and idle, when only one set are operable and the switching will occur at about 70% of full power, which is about where the air speed is high enough for the benefit of the outer injector positions to be effective.

When Colin tested his with single injectors and twins at Emerald some years ago, they saw about 7bhp increase at peak power improvement IIRC. Some people argue that a single position in the bodies works as well, but I doubt any of them have done a proper comparison like Colin did. To my mind, injecting slower in two positions in the air flow must inevitably give a steadier flow of even air/fuel charge into the cylinder, so it relies less on tumble/swirl to homogenise the charge.
My experience as I said above is that mapping and hence smoothness/flexibility in improved by twin injectors and it's worth it for this alone. I'm well aware though that many tuners/mappers are willing to accept mediocre results at part throttle, I prefer not to, because how the engine feels and behaves is often more important than peak power, even in competition.

I think he was stating that 4 injectors can flow enough for 350 bhp mate, not that it needs injectors that big.

i understand that bud, 600cc injectors are far to big for the intended purpose making it a bad example, but in short, 2 sets are better then 1 for bodies

after that it gets more complicated by placing injectors at the entry point of the itbs, the video gives a perfect example of how the second set would kick in at higher rpm giving much better AFR

17th June 2010, 11:35

True it wasnt explained correctly

I think running on a fairly standard engine, 1 set of injectors is enough, but if running high power/high revs, a 2nd set of injectors mounted pointing into the trumpets are good

Im running standard injectors on my Clio with 48mm injectors and they are still not near full duty

17th June 2010, 11:38

Also bearing in mind max revs for me is around 7500, if I install cams at some point I may look at slightly larger ones but we will see

running 8 injectors just gives the flexability to time each set to work in harmony with each other giving optimum air/fuel mix at both ends of the rev range, albeit more complex it allows for smoother mapping and a generally better map.

having injectors spray downstream from the itb entry point is very extreme and over warrented on saxo/106 engines

17th June 2010, 12:21

Thats great.

However as I said earlier, the OP isn't running ANY injectors, so the point is rather moot!

Meanwhile, back on the ranch, OP - get a megajolt and sort your ignition out with that. Cheap and cheerful
