Viewing: Best diesel engines to remap

***waynne*** · 27-11-2009, 08:28 AM

I thought I would do an article with a list of the best deisel engines to remap with power gains, cost and performance stats.

What are your thoughts on this?

VAG 1.9PD (150bhp) > Remaps to around 190bhp (anyone know the Torque Figures)

We should probably have the Pug 2.2 and BMW diesel engine but IMO the longer the list the better.

So which diesel engines with remaps give the best bang per buck?

**pgarner** · 27-11-2009, 10:06 AM

1.9 ARL engine is something like 300 - 320ftlb depending on map
Audi (doesnt seem avalible through the rest of the vag range) 3.0 TDI - around 270bhp and over 400ftlb
BMW 3.0 single turbo diesel gives similar figs
not sure on the twin turbo

***HDi fun*** · 27-11-2009, 10:21 AM

The 3.0 twin turbo BMW unit (335d and 535d) can be taken to 345bhp and 511lbft (source: Celtic Tuning).

(I wish BMW would revert to their standard and use the last two digits to denote engine size. It's confusing because the 525d 530d and 535d are all straight 6, 24 valve 3.0 litre diesels. A 520i is actually 2.2, 523i is a 2. 5 etc etc.)

VAG PD150 goes to over 300lbft

**pgarner** · 28-11-2009, 11:49 PM

found some figures that are RR confirmed for the 1.9 VAG engines mix of 130 and 150 engines.

250bhp and 400ftlb
248 and 377
230 and 344
from a 130
247 and 355
from a 150

VAG 2.0TDi (PD and CR) 167hp > 211hp; 258lb-ft > 351lb-ft

That's a straight remap from Celtic, they can take the PD to 300hp with some more indepth work.

Graham told me about the 300bhp project back in April 2006.

**WLBjork** · 30-11-2009, 09:33 AM

I haven't gone into that, I have a CR

I suspect it's doable (I note with intrest how the figures before and after are identical).

**pgarner** · 30-11-2009, 09:16 PM

yeah it was done on an A3. was running with propane, nitrous and possibly hybrid turbo

***HDi fun*** · 30-11-2009, 10:23 PM

Celtic's silly 300bhp 1.9 definitely used a hybrid turbo with cut back vanes. I think there were also some substantial changes to the cooling system and oil cooling arrangements.

**pgarner** · 01-12-2009, 11:42 AM

that was on the 1.9 thought it was them that had played with the 2.0.

not sure if oil cooling is really required most od the 1.9s i put above dont seem to have oil coolers and those who do only see the valves are open when its on a track

What models house this engine?

***HDi fun*** · 18-12-2009, 12:21 PM

Golf GT TDi PD 150 (that's a bit of a gobfull)

The only problem with the 4 cylinder PD engines is that they're a bit coarse compared to the French offerings.

**pgarner** · 18-12-2009, 12:29 PM

vag 1.9 tdi ARL engine was in the
golf
bora
and seat leon as a 160bhp varient

**Matt L** · 05-01-2010, 07:59 PM

My Astra H 1.9 16v CDTi (Fiat JTD engine) 150 standard. With a DTUK CRD2 box made 206bhp. Quick was an understatement!!!

**theballboy** · 05-01-2010, 09:41 PM

thanks for responses.
very interesting with regards to DTUK tuning box - I take it that it was a box and not an ecu remap.
that seems like quite a leap for a tuning box - 56bhp. Was this a quoted fiqure or obtained from a rolling road?
Do you have a torque increase figure

**Matt L** · 06-01-2010, 01:35 AM

Quoted website figure, but these boxes are renouned for making MORE power than their website states. A couple of the van owners with same engine were set on the lower powered map and made 210bhp. These are the good boxes with PROPER software not the cheap ebay #!#!#!#!.

If you go on Astra owners network, more of the diesel boys are running a DTUK box than a remap because they are simply awesome!

Andy (DTUK guy) is great and is on the phone 24/7 to assist you, really cannot recommend them enough. Fantastic product!

I take it the CDTi engines don't have particle filters then.

why would that come into play?

***HDi fun*** · 06-01-2010, 11:22 AM

Because of the additional injection phases required during regeneration. How would a tuning box know that the filter was trying to regenerate?

**Matt L** · 06-01-2010, 01:32 PM

Nope, no particle filter on the CDTi whether mine was too early to have one I don't know? (Seat introduced them to the Ibiza pd in late 2005)

The problem the Fiat/Vauxhalls face is the EGR valve and inlet manifold (swirl flaps) which is a costly repair (around £1200 I believe). I'm also lead to believe Vauxhall introduced a self cleaning EGR valve to as it is a known design fault.

**Poddy** · 16-01-2010, 11:04 PM

My Kia 1.6 CRDi was mapped from 89 - 125 but can go up to 140 without any mods.

and from what i remember seeing on the internet the 2.0 CRDi (140 std) can go up to 190bhp, though i've yet to meet someone with a remapped 2.0.

***HDi fun*** · 16-01-2010, 11:21 PM

That does sound about right. My deceased 2.2 Peugeot went from 136 to 190 without any issues and dished out outrageous in gear torque and pull.

Argh! I just wish it wasnt just after christmas, I'd be booking my Pug in for its remap whilst typing this!

**Poddy** · 17-01-2010, 11:37 AM

you can get your car mapped for about £180, that included a before and after dyno for me

Was that on The Mickey Mouse Rolling Road? Aircon, heater, radio, fan etc all switched off on the second power run and less resistance on the rollers lol?
