Diesel Remapping

I know there have been many a discussion about this subject, but as a newbie I'm finding it a bit hard to wade through the forums.

I live in Australia and there are remappers out there, I'm taking it that remapping is the best way to go. My recently purchased 147 DC comes with 170 bhp and 243 ft-lbs (125 Kw and 330 Nm), it's already pretty quick, especially mid range.

However, boys will be boys and out of curiosity I got a quote for a remap, to 200 bhp and 285 ft-lb (147 Kw and 386 Nm), with a promise of smoother delivery and lower fuel consumption.

It was from Quantum tuning (ECU Remap | ECU Tuning - Australia), well a 'franchisee' of this allegedly World wide tuning mob.

The guy said he would come to me, read the ECU, send the file to the UK for remapping and then burn the new file to my ECU. Standard fair by what I've read.

Thing is, he wants $1,500 to do it, which is roughly 720 quid as I type, which seems bloody expensive for "two hours work". If they can quote the increased numbers, then this isn't the first time they have tuned my version of the 1.9 JTDm. It is, in the end, just a computer file virtually cost free to send even half way round the World these days.

Just wondering what the experience is over in the UK with this, especially the cost.

Paid 290 for my remap with pretty much the same figures in the quote you have, stll need a rolling road test though to be sure. There are tons of companies who offer remaps in the UK but an Alfa specialist will know what's possible/safe with your car, it's good that the company have previous experience with your car so they should know what to expect. Note that extra strain on driveshafts/clutch for example is soemthing to consider but some mechanical sympathy will help preserve the clutch. As for fuel consumption I had an EGR delete with the remap which has increased economy by 4-5mpg depending on driving style, heavy right foot maybe It's good to be aware of any implications to your insurance also when you perform these mods. Just recently the UK introduced new regs which state you can no longer remove/blank a DPF if your car was factory fitted with one, UK 147/GT/156's were not fitted with these but it's worth knowing.

Believe me it's a slippery slope when you have a remap, you want more afterwards, it led to braided brake lines an intercooler and all the other bits and pieces that take your fancy.

Now: 156 GTA | Quaife Diff | Wizard Manifolds | Eibach Pro Shocks & Springs | Eibach ARBs | 330mm Brembo Calipers

Then: 147 Sport Q2 | Autolusso Remap | Swirl Flap & EGR Delete | Mocal Oil Cooler Kit | JTD Performance FMIC Kit | High Flow Elbow | Wizard Downpipe | PF Pads & 5.1 Fluid | Autolusso Braided Brake Lines | MTech Short-Shifter | Autolusso Silicone Turbo-to-MAF Hose | Refurbed Q2s

If you bought the hardware to read out the map, even if you went to a tuner in this country, you should only be looking at an absolute max of 200 to modify a file and email it back. Let's be honest, they will open it, increase fueling in the duration map and save it. five minutes work and you are unlikely to get any better from 90% of tuners around the world as that is what is easiest for them.

I will chime in by saying tuning here is a fair bit more expensive than in the UK. He will NEVER find a decent tuner for 200-250 quid its just not what is charged over here.

To the OP, most tunes should clock in around the $800-$1500 range depending on what services they provide. My advice to you would be to go see a tuner with a rolling road who will let you be present whilst they are doing their thing. That way they can provide real-time feedback to you and can also discuss options with you regarding power increases vs fuel usage vs reliability etc. It would likely cost you about the same or less as the $1500 you go quoted but would be a much better way to go imo. The real trick will be trying to find a decent diesel tuner but if you could make it down to Sydney there are some Alfa tuners who are held in high regard over on the Aus Alfa forum who would be worth a look

Got another quote, basically for the same type of deal. This guy reckoned that $1,000 is nearer, but would do it as a 'cash job' for $750.

Another quote involves;

Remove the existing tune file from the factory ECU
Modify the tune file with a better tune, and remove the DPF and where possible the EGR function
Remove the DPF from the exhaust and refit DPF Delete Pipe
Conduct a full DPF Regeneration and reset the factory DPF, Oil, MAF, O2 Sensor Counters (necessary to eliminate the Engine Check Lights and keep the ECU happy)
Replace engine oil and filter
Reload the new tune file to your factory ECU
Road test vehicle

This costs $2200 (1,040 quid). They reckon you can use cheaper oil from then on. You have to sign a waiver as this mod is not technically road legal.

The performance increase seems to be roughly the same as the first two, an extra 70 Nm, which would take it 400! (295 ft-lb).

Vengeance, your suggestion sounds much more sensible. It's ok reading the chip and reprogramming it, but in reality all that is happening is your chip gets read so that it can be backed up and the new 'script' is just a generic one that seems to work. Surely if the car can be tuned on a rolling road, the outcome will be much better. Whilst the extra ooomph is attractive, more appealing is lower revs to get enough torque to keep the beast happy in sixth and hence better fuel consumption. I do around 35,000 Kms per year (21,750 miles) so having a car that has such stunning mid range acceleration yet does that using so little fuel is brilliant. BUT making the car less reliable would be a pretty stupid thing to do.

Do you have any names for Sydney based tuners?, I do go there for work.

The KESS solution is one I'm also looking into.

Thanks to everyone for their contribution

I would definitely try and find a bloke with a rolling road in that case as they should be able to modify the power delivery to suit your specifications much better than a per-configured chip. Sadly I do not have any names off the top of my head but there are a few threads on the Aus Alfa forum regarding Sydney based tuners.

Iirc there was a couple who were highly regarded but not living in NSW I didn't really take much note of the name. Might be a good idea to ask around on the Aus Alfa forum and see if anyone can give you some advice!

Thanks Vengeance. I'll have a search and post anything of interest.

Just out of curiosity are there any 'rolling road remappers' in the UK and if so does anyone want to share their experience?

Knowing that the Chinese sell € 100 so if the European version costs an average of 700 € to 800 €.
It's been expensive for a product where one is not sure.

But if it really works it's a good deal.

Should be tested .......
