Berlingo 1.6hdi remap?

My previous model Berlingo / Partner has the 2.0hdi 90hp engine running a stage1 map (125hp)

When I first swopped the ECU over I was like "woooaaahhh rocket ship" however I soon got used to it and now it just feels like a normal car rather than a slightly too slow van. It doesn't overwhelm the brakes/tyres/suspension and it feels more like the power it should have left the factory with.

Gearbox and clutch have been fine.

No idea on fuel economy - it's always been very good so I don't keep track.

I think that engine also came in a 115bhp config, so should be possible to do something. It would be more for economy benefits that performance as you are still pushing a large brick through the air.

I had the 115bhp engine and it was fine...but it was never fast, it did overtake things, just not in 2 or 3 seconds.

I'd say give it a shot and see how it goes, just don't expect night and day differences.

Thanks all,

I am not expecting ferrari like performance just a little bit more get up and go and an easier cruise on the motorway.

I will continue my research.

I'm massively skeptical of any improvement to fuel economy.

Think back to before common-rail diesels and how diesel pumps worked (because it's easier to visualize).

You literally had a positive displacement pump that rotated the body to adjust the volume and timing in relation to the throttle position and the engines RPM and load (i.e. manifold pressure from the turbo).  If you wanted more power, you just dialed up the pressure from the turbo until the pump became the bottleneck, then put a higher volume pump in.  

That's what a re-map is. It's upping the manifold pressure (and thus airflow) and increasing the duration of each injector pump to deliver more fuel.  

In super simple terms you could re-map a diesel from 90-125hp by simply multiplying the signal from the throttle by 1.38 if the turbo id delivering sufficient air.  It won't be because too much air means more NOx which the manufacturer needs to limit.  So it needs a little more than that. But it shows how you can't have your cake and eat it and why the manufacturers don't do it.

I think that engine also came in a 115bhp config, so should be possible to do something. 

Assumes the same turbo and intercooler.  

More pressure = more heat = more NOx

And assuming the same injectors (i.e. longer pulse times, rather than just fitting injectors that deliver ~40% more fuel in the same pulse).

More fuel = reduced combustion efficiency = more PM (both visible smoke and invisible PM2.5)

And this isn't like taking your car / bike to a rolling road for a tune after doing some work on the engine to sort out the jetting.  It's someone with a laptop buying a map from another tuning company that has tuned a similar engine at some point in the past (or worse, just guestimating the values).

I know alot of young lads (my sons mates) that have re-mapped cars and things have gone boom - always needing repairs and having breakdowns.  If going for a remap, don't push it, See what the other engines in the range have for power. I've a 2.0 HDI, and I believe they come in all the way from 100 bhp upto 180 bhp. I've got the 180. It's probably got different injectors, revised turbo etc etc, and can be mapped easily to over 200 bhp, but I'm not, as it's already the most powerful engine, and you are pushing it beyond specs, more than remapping say a 100 bhp to 130 bhp.  Re-mapping does affect reliability. Worse case, a bad map can destroy your engine.

In my case the older M59 2.0 doesn't have an intercooler, that coupled with the exhaust becoming restrictive past stage1.

When I was researching -  there are only 2 companies doing specific PSA Hdi engines that were mentioning the difference between Siemens and Bosch ECU's and extras such as immobilizer delete (which I did). I wouldn't have bothered with a generic mapping place.

Mines been running for 2 years with no issues on a 21 year old car with 118k miles.

the 115 model has an intercooler and a different turbo - They also have a different gearing in the mk3 (B9 model) 

Its not just a map on an HDI 

you can take a 90 up to 115 on a tune but its just firing in more fuel. 

ive a 90 BHP B9  , i feel your pain on overtakes but then - im never in a rush . my other cars have 80 bhp and 114 (but weigh 3tonne) 

b9 1.6HDI between the 90 and 110 models has different turbo (VNT),  intercooler and higher flowing injectors. 

Can take a 90 to 110 but your just firing more fuel in. 

No wonder there are so many multiple posts on loads of threads ...... What a pita it's become. 

It’s worth it but get the remap done by someone reputable who doesn’t merely up the boost pressure and calls it done.

I had my 2013 VW Caddy 1.6tdi Highline that I bought in 2016 remapped by a mate on his rolling road from 102 bhp to 147 bhp and 330 NM, the van ran great and I gave it to my brother in 2019. 

Last year the turbo oil seals buggered up but it had done 148’000 miles so it was expected, a mate stripped the head down and with a bit of work and setup with a larger turbo and new injectors as well as a new clutch etc it now does 169 bhp but 410NM of torque which makes it fly.

It cost a fair bit bit but well worth it as the bodywork is mint.
