Omex vs Megajolt
Turbo Mini Forums

I'm new to this forum and have recently purchased a complete turbo set up from richturbo on here. Just trying to gather all info needed for when the engine goes in.

I'm at a cross roads at which/what engine management to run. Most people seem to run Megajolt which seems reasonably priced. I was wondering if anyone uses Omex 200? It looks the dogs but is of course much more expensive.

I'm not all that worried about the cost of either, I just want the simplest and easiest set up to install and work with. The chap I use for rolling road swears by Omex and so do my friends who have also got it installed on their road cars (not mini's).

Basically, has anyone used Omex on their turbo set up and against the Megajolt, is there any main advantage?

Thanks!

Wolfie used omex iirc, seemed to work well, most people use megajolt, megasquirt and emerald. Personally I will going to use megajolt for cost but possibly megasquirt ms3x as I have some friends in the states and can get it for arround 300 gbp

Searching is all you need on TurboMinis

I had omex 200, its a good bit of kit the downside is no online help or forums to help when mapping unlike megajolt and megasquirt

I'm more tempted by the Omex as everyone I've asked pretty much has said its very good. Do I need a TPS and MAP as that is what I understand from their website?

Ive only heard good things about their help to be honest. In the worst case they are only up the road from me so I can knock on their door!

I used omex, Very easy to tune, but there all much of a muchness, with the knowledge on here though, if i were to do it now, i'd go megajolt/megasquirt route.

What type of injection are you planning?

1) 5-port head siamese code
2) 5-port head standard code
3) multiport head with 4 inlet ports

I would only use MS for option 1 to be honest.

If 5 port and ignition only then surely either Megajolt or any of the other ignition only options.

Although some of the injection systems provide a lot better logging facilities for ignition only even if you don't want injection.

But Wil, I'm confused....

Schrödinger's cat - so which one am I ???

Yes it will do everything. What it does especially well is siamese port injection. All other ECUs will cope with 2 and 3. And Having used MS and other ECUs I found the others better for various reasons.

Some I'm sure are worse, but I have just never got on with my MS. Personal opinion really.

Omex also offers idle control, by varying spark advance, according to target rpm and water temp, but you will need a TPS sensor and water sensor. Also you don't need the ford Edis Module (unlike MJ), but you will need to either buy ormake a suitable loom. If going the omex route Id also use a air temp sensor to retard ignition at extreme high boost temps, to safe guard against det.

If using omex, you can still replicate MJ maps, by scaling the software to match. There are plenty of MJ maps floating around on this site.

Thanks for all the replied guys. Im not really at all familiar with this side of building the car, hence why i sway more towards the Omex side as it seems a little more 'plug and play' than the Megajolt. The car is non fuel injected 5 port so which ever i go for will only be ignition only. I may ring Omex and get a real costing (as there website is a little unclear). Im sure i will have many more questions about this!!

Having used a few different ones, not Omex as it happens, on the ignition side there is little to choose between any. Cost varies a lot and I don't believe in this case that you get what you pay for.

I am amazed that people are still going down the route of choosing an ECU based on what the local tuner is used to. In this day and age any half decent tuner should be able to get his (or her) head around a new interface to tune an engine. The art is in knowing how to get the best not what buttons to press. And lets be honest tuning ignition is not difficult on any modern system.

A man without a project is like a like a woman without a shopping list.

Agree, however if paying by the hour, having their preferred ECU, can save time and money, as knowing all the short cut buttons is a god send. To be fair this is more on fuel and ignition mapping.
