Title: Chip tuning my omega 2.5 td manual
Post by: Garza on 01 April 2013, 12:26:26
Hi all.m
Recently I have phoned a couple of tuning specialists here in the north east.
some say with mine being the 2000 model (xreg) it needs chip tuning. Instead of a remap
one of the company's said they can't get hold of the chip set for my car so they can't do it.
While the other said they'd fit a sort of plug and play box in and adjust thing through that but I would be better off getting one for cheaper off eBay.

now I'm confused with it all and need some help.

has anyone had one of these plug and play boxes fitted??
Which one did you buy? And did it fit to the fuel pump or did it plug into the common rail.
and lastly did it make your car more drivable?

Or does anyone know where I can get a chip set I can have installed into my ecu.
I think this would be a better way of changing the characters of my car that I need addressing.
Is there anyone on here who can point me in the right direction
Cheers Gary

the only way to do it is via an ECU chip, and it's very worthwhile!

That would suit me fine. Do you know where I can get it done by any chance?

Not personally, however there are some members on here who know where to get them, I'm sure someone will be along soon :y

And yes, I chipped my old TD auto, and it transformed the car's drivability. Still no race winner, but a much nicer car to drive.

His profile says manual, so assumed that's what it was  :-[

Ooooohh, likely a 427 ECU. The best IMHO (or at least the quickest TD I've driven was Terry the Chipman's 427 TD estate).

Omegatoy's 214 TD estate, with all its tweaks, went pretty well as well, but not as quick as the Chipman's

I can put you in touch with the guy who supplied mine, and a few other members.

I think he charges £70, so long ago, I can't remember  :-[

If interested, PM me you contact details, gearbox type (I will forget again ;D), and the ECU type (probably 427, but you need to visually double check yours), and I will get the guy to contact you.

It will shred your autobox. Omegatoy got about 100 miles from his before chewing the auto to bits, I got through 2 AR25s within a couple of months.

You need to change your autobox to an AR35 first...  ...or convert it to manual. I don't think the TD and an auto is a particularly good combo.

i have driven one that had the box done think it was by autotune and it went a lot better than mine did.

Hopefully putting in the AR35 box this w/e which I have had for at least 3 years. Then the full fat chip.

A thought occurred this AM, (I have about 1 a day). What difference will the Sport mode make when the full fat chip is fitted? :-\

If you have the latest gearbox ECU, don't need sport. Can't remember if I used sport mode much on my old tractor...  ...used to lock it in 3rd a fair bit to stop the 3rd/4th constant hunt at around 50mph.

Any from a 3.0 or 3.2 omega.

Need to reuse your current TC and bellhousing.

Ooops, I didn't realise that I needed another ECU also. Unless this is already attached to the box. Better have a look tomorrow. :-[ :-[ :-[

You have the ecu, its what software is on it.

For a TD, I'm not convinced its worth paying the prices I charge to upgrade the gearbox's firmware. The petrol ones, yes, definately. TD, not so sure.

Hard to remember now. I don't think it made a significant difference to be honest. Still hunts around gears at about 50 if on a slight uphill slope. :-\ It will be interesting to compare with the AR35 and the V5 chip. :y

I used to lock mine in 3rd if doing that 45-50mph constant speed on roads that have slopes, as the constant locking and unlocking of TC was annoying. At least if in 3rd, the TC stayed locked, which probably improved economy anyway.

I do ocsnly do that. I guess the V5 chip will not affect that annoyance. :-\

Not really, but as the boost seems to come in a bit lower, I felt the range of speeds for me having to lock in 3rd was lower once chipped.

I have finally had my ecu chipped. And I have to say it has made a massive difference my car now pulls much stronger in every gear. My turbo starts to spool around 1700rpm rather than 2400
Overtaking has become so much easier too. In short it has given me a fully drivable car again.
Beforer the re chip my trip computer was giving me readings of 20-22 round town and on a run it was 40-44. with this chip its reading 36sh round town and I averaged on a 180 mile round trip 58.6 mpg. not sure how accurate the trip is but that's a massive difference and the fuel gauge only moved 2 notches. I'm going to manually work it out next time I fill up to see if these figures are correct.
but I would recommend it to anyone.

After 3 days, I definitely feel that the gearbox performs better with the chip, does not hunt round for gears at 50ish on an uphill slope. I wonder if perhaps the original box ratios were chosen measured against the BMW performance, ie as now chipped. :y

IME, the MID will over estimate MPG by around 15% once chipped.
