Hi all not posted on here for a while since my Omega finally became beyond economical repair however I have been lurking in the background of the to see whats going on. I now  drive a Insignia Elite  2.0 ltr Bi Turbo diesel and am considering a remap so looking for advice should I just go for a remap done by a specialist or a plug and play tuning box which suppliers claim will give the same gains as a remap any advice would be gratefully received. TIA Tony

Remap done by someone who knows what they are doing

[Raeturbo]

Your best bet is to have a bespoke map done on the car by a good reputable tuner of course, but it’s going to be expensive if you don’t fancy that  I’ve found Celtic tuning to be good for just the generic map for that type of vehicle. I would leave the tuning boxes alone myself.

It’s my understanding that plug and play and ecu piggyback chip tuning devices just fool the ecu to increase fuel/air mixture for more power, whereas the more developed remaps adjust and recalibrate a much wider range of ECU values and can have a more positive effect on the economy as well as increased power and smoother power delivery.

On my Audi, I personally went for a remap by a specialist, but it does mean that I can’t take it to an Audi main dealer (unlikely anyway as I use an Indy), as they will run their software on it and possibly un-remap it.    Any main dealer will know it’s been remapped, contrary to what people may tell you.
I didn’t do it for outright power or economy but the power delivery is smoother and punchier low down, making overtakes quicker and safer.   

A plug and play device is removable if required but I’d avoid generic devices unless it’s supplied by a reputable company, and tailored for your specific vehicle. If going that route, I’d advise researching what success others with your type of vehicle have had, preferably after many thousands of miles of having it fitted.

Indeed Celtic take time on research and development and map your ECU, however tuning boxes are hit and miss and I wouldn’t plug one into any of my cars. (Although mine are done uniquely to my vehicle on rollers then the road with det cans👍)

Yep. When I enquired about have the Adblue system deleted from wife's car (it's a pain when the weather gets cold) the guys who do it told me it wouldn't do any harm to the car at all. But, if it went to the main dealer and they plugged it in, they would know I'd had it done. It's not out of warranty until July, so if it plays up next winter, it's getting done.

I can tell you the very first thing Main Dealer BMW diagnostic software does now (10 years ago it didn't) is check for a remap, it then lists everything that is now excluded from warranty (pretty much everything).

Hi Tony, Good to see you about, how you doing?

[YZ250]

I should have added that obviously the warranty issue is only relative if the vehicle is actually under warranty. If it’s out of the warranty period it’s not an issue. Just make sure that whoever is working on it knows that it’s had a remap. 

[biggriffin]

You can buy ad-blur Emulators for trucks, they just plug into obd port, and the adblue system doesn't work, there are some around for cars, cost about £30.

Hi Tony, Good to see you about, how you doing?

Not to bad Jimbob thanks for asking Hope your well 

[TheBoy]

Another vote here for a proper remapping, and not use tuning boxes.

Great to see you on here again Tony H
