My remap nightmare

[Morgan]

So had a remap a few weeks ago in Cardiff, few friends have had one there and had no problems at all. Had it done, felt hardly any difference. It's a 2012 2.0 Cdti.
Put my foot down in 6th, straight into limp mode because of overboost. Guy said he had adapted an insignia map to suit it. Took it back and they changed it, no more limp mode but still hardly a difference, and poor fuel consumption.
Took it do a dyno, got figures of 167 bhp and 390nm. Torque has improved a little but hardly any bhp, 160 standard.
Now they are saying it's probably a turbo problem. I don't think it is tbh, any one had problems with remaps on this car? Or any suggestions what it could be? Thanks

You had it remapped but only gained 2bhp from stock? Seems dodgy that bud least gains usually around 25

What type of remapping service was it, did they just do a plug in and play map ?

They made it themselves apparently. Ecu out job

I know there were lots of issues with using tuning boxes and having Astra's re mapped after a recent software update, the fact it was a previous insignia map doesn't sound great to begin with. Who was the re map done by ? I was disappointed with my map as my 160 only made it to 190 compared to some of the figures I have seen on here I felt it was low but still feels good to drive however i would be quite disappointed with the results yours achieved with their map

Ps the issues were normally with plug in and play maps instead of purpose written ones

Thanks for the replies. It's being done with a1 remapping in Cardiff. I tried using a tuning box before, that only gave 170 bhp. I'm stumped on this one

[Starie]

Sometimes if you have had previous equipment changing the parameters of the vehicle like a tuning box it can effect it

I'm sure someone on here will be able to advise you better I'm not sure

My remap going to give me 60+ bhp but that just depends who you take it to and how good they are I guess

What engine have you got and where's it going ?

[Hawki341]

2013 2.0 cdti astra ecoflex elite 165bhp and a place in Birkenhead, currently saving up to get it done now should have it done by early next year

Does sound like a large gain be interesting to see when it's done the torque figures aswell


Sent from my iPhone using Tapatalk

[Hawki341]

Aye it is but that's including dpf removal, egr, factory speed limiter removal and basically everything you can remove to add performance without hitting stage 2 yet plus all error codes cleared so it will pass mot still

Sent from my SM-G920F using Tapatalk

[Starie]

That's more realistic with the removals as well, have you seen the plans to introduce more in depth checks on DPF's during MOT's ?


Sent from my iPhone using Tapatalk

[Hawki341]

Yup spoke to my guy about it he says he removes the internals so on paper it is still passable but I'm not sure whether that will include the new rules or not but hey ho it's getting done for the bhps

I like it only one way to find out, if it fails just need to find someone that will be happy to pass if he does the work I'm sure he can find someone

Yup girl I know with a vxr knows a guy for who is lenient on mots so will swing his way probably if all else fails

Was it done on a rolling road?

I would not buy the turbo issue.

I'm planning on having my done next year with DPF & EGR delete, I'm going to a place in Kent that @Dicko1 has used.

No, it was not done on a rolling road. The dyno session was done separately in a place called gotboost

[Rusty2009]

I wouldn't have a map unless it's done on a rolling road.

I would get them to remove the map give you a full refund and go elsewhere for it to be done.

You paid for a service and they haven't provided it, I would do the same as what Rusty said and ask them to remove it and get your money back.

So after some discussions with them, and trying to make him realise the turbo is fine, they are going to make another map, how without the car or a dyno I don't know, and put it on next week. If this doesn't work, I'll be getting my money back. He seemed to suggest it might be the wastegate being stuck open at time, which I believe would stop it making any boost, and suggested some fuel additive next time I fill up...

[Rusty2009]

I've had a sticking wastegate and had a new turbo, fuel additive will not help the turbo.

The only way to have a map done that suits your car is on a dyno. It sounds to me this company are just using a fits all map and tweaking it here there without any tests.

Thanks! What are the symptoms of a sticking wastegate?

[Rusty2009]

Underboost / overboost and going into limp mode with no power until you restart the car.

[Starie]

This was what I was trying to suggest with them saying it's an old insignia map there's not one fits all and when there is it's cheap and with problems

Thanks, been measuring boost through torque app and its kicking in around 1800, up to I believe 22.5 psi. This sound right? Since the newer map haven't had limp mode at all

[Rusty2009]

Normally boost kicks in between 2000-2500 within that range.

basically correct the ecu has to be removed on the 2.0 cdti and a custum map written
but there is also a code to overcome before they can rewrite it not every mapper can do this
you have just been fobbed off they have not done it as there is no gain what so ever
if you had turbo problems you would be seeing large dips in power and as the dyno showed
your car is fine and putting out the correct bhp a couple of bhp either way is normal
so my conclusion is no job has been done they are fobbing you off and charging you for there time
i would only use a mapper who has mapped a 2.0 cdti 2012 to 2014 as that's when the ecu gets tricky to map
and the ecu has to be taken out

most likely trading standards for you mate
get them to put the standard map back on get your money back and go somewhere that can and has proven they can do it

[stigeye]

As above.. they do not know how to do an Astra J map as far as I can see. There is no point in keeping something that has not made any noticable difference to the performance of your car. People like this who don't fully specialise in custom maps could end up damaging your car in the short, medium and long term.

Can you elaborate on that code to overcome please mate?

[tucpal]

its like a theft protection code it needs unlocking with a code as said not all mappers have it

[marcus01]

Yeah sounds like the mapper wasn't able to write back to the ecu or wasn't up to the job

Had mine remapped by a company here in northern ireland called torquetronix, guy is very good at what he does.
Not had any issues with mine at all

[Morgan]

Update, took it back this morning, hes keeping it overnight. Said he was working on it for hours. Still keeps suggesting he thinks the turbo is faulty which is why it won't boost properly and is giving an overboost error code. Most unorganised and amateur company I have dealt with

[tucpal]

sorry to hear that

[J1ODYA]

Why did you leave them your car then?

Sent from my SM-G920F using Tapatalk

[Morgan]

They asked to have it for the day, I agreed because I just wanted it sorted. Wandering round Cardiff for a few hours, get a phone call, ecu is still off and we close soon, we're going go need it overnight. I was too far to get down there and needed to get the train home

[marcus01]

Got your car back yet?

Sent from my SM-G930F using Tapatalk

[Morgan]

Sorry for the late reply. Got the car back the following after noon. Felt more responsive and more torquey straight away, but my heart sunk when clutch slipped a few times towards 3500 rpm. I took it easy and priced up a replacement, circa £1000. Couple of days later it stopped slipping, and hasn't slipped since. Got it on a dyno and had around 190 bhp and 400nm. Could have been better but not bad. Will post the dyno runs if anyone is interested

[J1ODYA]

Just glad you got it back and are happy!

Nice one glad you got it all sorted.

glad hear you cars back up n running mate, must of been a complete nightmare.

I have a gtv 2.0 cdti 165. any one know of a place with a good reputable that remaps near east yorks\lincs.

Glad you have it done now
