Ecu

Well they can be on some Saab ECU's and some of the Vauxhalls share the same ECU's courtesy of GM.
 
Hi T9 had a look at your gallery pics car looks awsome very nice spoke to a local tuning shop about getting my insignia remaped but there are a couple of hurdles to cross first they have said that vauxhall have starting using lock out codes and the second is the DPF needs to be removed which can cost quite allot to do is this true .
 
Thank you for your kind words buddy, glad you reminded me as I need to upload the latest batch of photos.

The DPF removal can be expensive or reasonably priced depending on where you go and who you talk too. I am a petrol head through and through so I cannot recommend anyone in your area for diesel works i'm afraid.

Google would be your friend here and see what comes up.

If your lucky, pgarner who is a member here on TC and is widely considered to be an all round diesel guru who just happens to hail from Scotland. I think he has had the DPF done on both his Bora and his current Skoda (I could be wrong on the exact details here) so he might be best placed to suggest a company for you to use.

Good luck buddy
 
The Bora was petrol - no DPF :)

You don't necessarily have to remove the DPF - my Peugeot retained it after remapping and there were no issues at all.
 
In truth it would probably be better if it was removed - you have to do this physically and you also have to code the ECU so it doesn't 'look' for it.

The earlier DPFs were possibly superior to the current ones since they used a fuel borne additive which lowered the combustion temperature of accumulated soot, thus enabling better burn off when the DPF enters a regeneration cycle.

Later ones, termed passive DPFs, do not have this additional complexity but as a result they are more prone to blocking.

Some people have been quite ingenious with the DPF removal - they've dismantled it, drilled out the core so it's little more than a straight pipe, refitted it and then coded the ECU to ignore the pressure differential across the DPF. This is the mechanism by which the ECU determines whether or not to put the DPF in regeneration mode.

One disadvantage with removing it (the DPF) is that the cat (which is a diesel car is an open loop unregulated two way device) will be subjected to soot particles that otherwise would be dealt with by the DPF. Whether this is a problem I am not sure - diesel cars have been fitted with such cats for far longer than DPFs have been in existence and I am not aware of reports of cats being poisoned.

Celtic tuning offers a remap service for your car - they are quoting 226bhp and a whopping 352 lbft !! Celtic's figures are sometimes on the optimistic side but if you saw 210bhp and 340lbft you'll have one seriously rapid Insignia.

Well thank you HDI lot of techy stuff there not sure if i know what it all means but get the jist of it have sourced a local tuning shop for the re-map but have been told that because its a new insignia a may well have ECU lock out codes programed into it so the DPF which they can remove and they have a custom pipe section to replace in the gap would be fruitless if they cant reprogram the ECU unit to tell it its not there was also considering a turbo upgrade whats your thoughts on this 200bhp claimed on jist re-map.
 
200bhp should be easily achievable with the standard turbo. The fact that Celtic lists your exact car suggests that it either isn't locked or they have found a way to unlock it. Of course they are simply quoting 2008 onwards, we don't know whether GM is using a different ECU in later models. I suppose the only way we're gonna find out is to let them have a bash and see whether they succeed. You certainly won't do any harm trying.

Upgrading the turbo will require the ECU to be remapped in any case. If the OEM ECU is locked then your only option is a 3rd party aftermarket ECU. I suspect this is gonna be serious money.

The hardest cars to crack are Toyota and Lexus models - pretty much everything else is doable. So far anyway.

Keep us posted !!
 
Will find out on Tuesday tuning shop are speaking to some nerdy guys who are experts in computer programs they might be able to hack into the ECU and bypass the blocks then all should be well with the changes wont be a rocket ship i think but a more even pull through the gears and a bit more umph would be nice have a few plans for this car and well on the way but learning as i go along your advice is very much appreciated knowledge is everything.
 
You'll be staggered how much more shove you get. You'll spot it immediately you ease that pedal down. Torque is king. A good tuning company will smooth out the whole power delivery across the rev range.

I had my 406 2.2 HDi (unusually in that era it had a 16 valve head) and the midrange was sublime. 30-50 mph was circa 3 seconds in third gear, for example. Celtic Tuning did mine, incidentally.

Significantly quicker than the BMW 528i I use at the moment.
 
Will have to keep the fingers crossed that the clever guys can sort this one out might have to let the insurance people know about the mods dont want to give another bullet in there gun excuse not to pay out. 528i what does this mean in the BMW world ?

No might about it buddy, tell them everything! Every single modification on the beast is fully declared to my insurance company. The modifications will not cost you anywhere near as much as you think they will on your premium - the cost of not declaring the modifications however is immeasurable ;)
 
It's a 6 speed Steptonic Auto, circa 200-210bhp 24 valve straight six of 2.8 litres. Loves revs and does go very well if you let it have its way. But it doesn't have that phenomenal midrange madness that you get with a well set up diesel.

And DEFINITELY disclose to your insurers. That is imperative.

Sounds expensive to run but a classy car. I hope the insurers will be gentle do you have to contact them about all mods each time you do something.

In a word YES! After every modification done to the car give them a call and tell them. Several times after I made some particular mods to the car, it actually cost me nothing extra on the insurance premium.

Ir's bullet proof. Well designed cars. Mine's at 131,000 now and drives beautifully with ice cold A/C, perfect arrow straight tracking and fuel economy isn't bad at all
 
Sorry not on here as much and it was just luck that i picked up on this :)

Yes the codes can be beaten quite often is just a case of finding a specialist and its not a 5 min job as bunging on a gereric remap.

My remap although generic took around 3 hours to put on my ecu as it is a case of ECU out and flashing it on the bench rather than through the OBD2 port

Courtney Sport are specialists on the VX
they list the insignia on their custom mapping. and superchips do up to 2011 by their list for generic mapping.

The DPF can be around £1300 on its own then fitting. cost me £430 to have mines removed from the octy and the map adjusted so its not looking for it and not much more gain on my insurance.

theyre a bit away froom you in norfolk so it would be a couple of days away

Not on often either work commitments but thanks for all the info there is a couple of more local tuning shops nearer to me that should be able to handle this work O.M.G performance tuning seem to have a lot of techy know how my next concern is the warranty with the dealers and whether they will honour it with the modifications.

If it is still under warrenty, I'd be careful when it next goes in for a service as some dealers have been known to wipe a full custom remap! Let them know before you go through with it as it might void your warrenty.
 
Well had some bad news today was told by the tuning shop that my car is fitted with the latest ECU 17 and not the 16 unfortunately this means that or at least ive been told that vauxhall have installed codes to stop remaping & DPF removal.
 
The new Vauxhall Insignia & ECU remapping if it has the ECU17 then it will be lock out to any changes including DPF removal if it is the ECU16 then you should be ok
 
OK - shame it's an option that's not readily available at this point. But......

Wait and see - at some point someone will crack it and at that point you can proceed.

I will say this though - Avoid tuning 'boxes'.

Are tuning boxes realy not a good idea then ?

They are bad news in my estimation. No way your car's ECU can control the engine properly when even the finest of tuning boxes mis-inform the ECU and force it to over fuel. That is not a controlled situation and as such I find it unpalatable.

I had a major dispute with a certain member over this a couple of years back. He threatened to sue me for malicious falsehood for simply stating my opinions.

Clearly that was going nowhere - wish he had instigated legal proceeding against me as he had threatened to do.

Shame really cos I was looking forward to chewing him to pieces formally in court

This happened to me at a Peugeot dealer back in 2007. Was not hugely impressed given I had told them explicitly NOT to re-flash the ECU.

IF I want something to be or not to be done when I put my car in 4 service I make sure they write in down on the card and initial it as in the past have had some boofhead mechanic ( woops:embarrest: they now call them technicians to justify the stealerships woops again :embarrest::embarrest: I mean dealerships very high hourly charge out rates) throw out a perfectly good K&N filter despite the K&N sticker on the cleaner:mad:.
 
Yes it would seem that the dealer ships make up there own minds despite having specific instructions to authorise any works required to be checked with the owner that would be us before carrying out the works required which i must say seem to be on average mostly imaginary the latest saga now with my ECU unit is the one set of professionals claim it cant be done the other say they can do any insignia remap lock out codes or not difficult to trust anyone when you cant get straight forward answers to straight forward question have put a padlock on my KN
 
You're dealing with EDC16 and ECD17. Not ECU16 and ECU17.

Loosely translated it's Electronic Diesel Control.

Manufacturers try to make things impossible to play with.

It will be crackable - just wait you time.
 
Took your advice & contacted Celtic tuning they gave me a number of a agent on there behalf to do the tuning who i contacted and they seem confident that they can map the car without any problems downside is that they need to open the EDC 17 to connect straight to the eprom chip .
 
That sounds reasonable. It's a perfectly legitimate means to remap an ECU, just not quite as elegant as going via OBDII.

What you're doing is different to the older style 'chip tuning' where a standard chip for your model is dropped in.

Celtic will build a map for your car and 'burn' it into the EPROM.

Trust me you will love the results..
