Sorry, was not meant to sound negative. It was based on:

Both 250bhp Omega I've seen - both turbo'd - had bottom end issues.
A 25% increase in ponys (compare to when new - it would have lost loads since) is a big ask. Being in mind, without work, you're not going to be able to get it to rev much beyond its current redline.
Omega is a heavy car, so you can't compromise too much on low down power, and retain any drivability.

Given the costs involved to go beyond much beyond 10%, the V8 option doesn't look expensive, and makes a better starting point for tuning - both in initial power, and availability of tuning parts and info.

I think sticking with the V6 is backing yourself into an expensive blind alley.


But if thats your desire, best of luck with it, and let us know how you get on

maybe you should go and buy yourself a v8 then, i love how i post a question about my car to see if i can get it re-maped and a few people are basically putting me down, well i dont see ANYone else doing ANYthing to their omega's so its more then some, the v6 is getting tuned and thats that, if i want a v8 ill buy a car that comes with one from factory, but thanks anyway

Maybe its better we should all lie? Yeah go ahead, spend a fortune in persute of the impossible, knock your self out. Nobody wants to see you waiste money, hence the opinions.

I tell you what. You show us a before and after increase of 50bhp and I'll personally give you £100 of my own money. Provided...

It's naturally aspirated.It ain't gona happen. But if it does, I'll be the first to shake your hand mate.

I tell you what MATE  how about you jog on, i could'nt give two sh*ts about you opinion, you've been on this site since yesterday and you come on my thread giving me sh*t, ill listen to others but not you, go buy yourself a v8 or what ever you get off on.
Before and after road tests are on the same dyno.
And it lasts 10k without bottom end failure with the same sealed ecu as the dyno run.

I think you'll find he knows what he's talking about but hey, we've all said similar

No need to be rude about it though... As I've said already, best of luck with it.  Watching with interest as if it proves worthwhile and at a sensible cost I could be interested

I ent being funny mate but i have taken in what you have said and others but to be honist i find alot of people's coments rude, its like all the plans that ive got for my car that i want to do and proud of doing on my car, plus in the process of, i should basicaly stop and not really bother and get a v8 or aspiration, but cheers anyway

In the 5 years or so the forum has been up and running we have seen 2.0 turbo'd Omegas, V8 Omegas, V6 turbo'd Omegas and even an Omega with a Lotus Carlton engine so you aren't the first to try and make your Omega quicker and you wont be the last. It will cost a small fortune to try and get 260 BHP from your 3.0 and it will more than likely reduce the life expectancy of your engine. If you want to make it quicker and not spend too much personally I would try and loose some weight from the car

Good luck with what ever you try though

There's a lot of experience on here and we're trying to help you and save you money and/or heartache if/when it either doesn't happen or does for a short time before knocking out the bottom end.

It is a proven fact that tuning a modern, NA engine rarely yields much more than a 10% increase so looking for 25% is ambitious

But hey, you're sure you can do it so we'll wait for the results As said, by myself and others, if you find a way to do it at a sensible cost then we're very interested

As for rude answers, the only ones I can see are yours

But in answer to your initial question, yes it can be re-mapped as it's just an EPROM, which has already been said

Indeed.

Having said that... If I were setting out to get the best possible power out of a natasp engine and had gone to the expense of hot cams and gasflowed heads I would bin it and go for an aftermarket re-mappable ECU.

That way:

1) You're not limited to using all the original engine ancillaries - intake setup, MAF sensor and injectors that might not flow enough, for example.

2) Every time you need to tweak it, you're not committed to going back to the original tuner for a mapping session and getting him to blow another chip. You, IME, do a lot by getting yourself a wideband O2 sensor and tweaking it on the road with a laptop.

Using the original ECU is a false economy IMHO.  Bear in mind that you might need to fit a non-TC ABS ECU, though.

well thanks guys for what i would say the usefull information rather then the dishope info, but just to say i went and got her back tonight from torque techniques and it sounds amazing, and fair play to the guys that made me the sytem, he must of had so much ball ake from trying to make those manifolds up, there is no space to work on under the bonnet lol, i will up load some pics as soon as i can

Dishope info? Or a reality check? Not to mention lack of manors.  As said the only person being rude is yourself. No need for that attitude. Perhaps you missed the forum rules on the way in?

Indeed. If there's one bit of that engine that's visibly sub-optimal, it's the exhaust manifolds.

Tubulars are the best mod I've done, plus I've been advised not to mess with the ecu on numerous occasions - unless changes are radical as it causes issues that have been echoed here. Air/fuel/breathing - but I've not done any of this on a MIG. Would love to see (immobilisers/management and random other crazy hurdgles notwithstanding) how an 3.0 ran on 2.5 Cavalier management in a MIG!
