Chipping 2.0 Hdi. 90 bhp

Anyone with experience of chipping the above engine? Either in-line box or
ECU adjustment?
Please share the pro`s/con`s. My own priority is motorway at 70/80 mph and
increased
wear/tear on engine ?
Happy Motoring
Wally

 

An intercooler would be a good start (110bhp then) then maybe a chip.

Hi Wally,
I have a HDI 90 and have had it chipped.
I looked a various differant companies all with varying prices at around
£450.
I found a company on the net http://www.motorsportworld.co.uk/ that will do
it for £250.
I rang them and they claim that the chip they do for the ECU will give an
extra 23bhp.(this will give more tork at lower revs.) and use less fuel. The
engine is normally govened so it will run foever in any condition and if its
not serviced. so chipping it will put it back to what it should do as long
as you service it regular. So in effect your not making the engine work
harder, just putting it back to normal.
You have to send your ECU to them, they chip it and send it back the same
day.
I wanted mine chipping because I'm a sad man with a caravan, and I wanted a
bit more tork.

I have seen a differance and glad I had it done. People on this BB may say
you should have bought a HDI 110, but the differance was £2000 and the HDI
90 I bought was in mint condition.


Hope this helps

Richard

 

Thanks for your thoughts on chipping. Money played a part in my buying the
90 rather than 110 but ,
that`s life. I shall look at the £250 offer, it is very competitive in
comparison to anything elsewhere.

So are you saying that the HDI 90 has no intercooler or a different
intercooler?

All Turbo diesels have an intercooler.

On modern cars and especially with disels you can't really increase power
without modifying the software

You can mod your engine all you want (big exhaust, KNI filter, large air
charge cooler, blah blah) but at the end of the day the ECU is programmed to
know its a 90bhp car that does 50mpg.

Your ECU won't sit there and go "Christ! Now I can suck in twice as much
cold air .. so I will go faster" it will say "Hang on a sec, I don't want
that much cold air right now, I better reduce the boost or I'll have to put
more fuel into the mixture to ballence it out and therefore I'll be dropping
the mpg to 35mpg which I am not allowed to do at these engine RPMs"

This is where a larger intercooler makes a difference.

Now your cars a 90bhp HDI, its a hot day, and you put your foot down. The
car is not 90bhp in all conditions. The air is too hot and not dense enough
so its more like 80bhp today.

Now you have a big intercooler and its hot again. This time the air is half
the temperature and much denser, therefore it can deliver the full 90bhp.

IF you want your nice new big intercooler to make a positive effect under
normal cool weather conditions you need to reprogram your ecu to tell it its
a 110bhp car
so now, when its got the airflow and fuel available to it, it can produce
110bhp under good conditions.


The last thing I would like to say about chipping is £250 is a rip off for
less then 5mins work. As an electronic engineer, I have several device
programmer and adapters for TSOP etc, so if I had the software, I could chip
the car myself for a couple of quid for the blank eprom chip (if the one
already in the ecu is erasable then it would cost nothing)

Oh, just remembered another thing. The D series 406's can be rechipped in 10
seconds by plugging the programmer into the diagnostic port under the
dashboard where the fuse box is. Superchip do this 10second operation for
£495 .... now you can't get more of a profit margin then that!

I'm not sure if the older shape 406s can be done by the diagnostic port
(quite probably as peugeot use this to download ammendments into your car
when on a full service)

As with most of peugeots identically sized engines, the difference in power
is down to the software

 

I've had my 306 90hp chipped by superchips. It was £500, but I didn't
have to send the ecu away and have my old ecu in a box if I want to
restore it.

The difference is noticeable and I would imagine going back it would
feel a bit weedy.

As an example, I followed a Puma from about 30mph on an dual
carriageway up to 70 and did not lose any ground - have also done the
same with 2.0 petrol mondeo, so it's no slouch.

I haven't had any problems, and the garage I had it done at had not
had 1 car back and they've been doing conversions for 3-4 years (it
was lotus).

Check your insurance company isn't too hard on engine mods.
It's intercooler and electrics on the 406 that's the difference.

 

So are you saying that the HDI 90 has no intercooler or a different

the 90 has NO intercooler
the 110 has an intercooler

Not this time. Could explain why loads of HDi's are blowing headgaskets
before 60k. (if your lucky to get that far). Known problem.

 

I have an intercooler in my hdi-90

I didn't know about them blowing head gaskets before 60k

I'm up to 74k in mine, i've had loads of niggling problems and now when cold
the head rattles like the cams are worn ... this could be a sign that bad
things are to come then

Sorry Guys-- I started this but it seems to be getting awfully complicated.
Can anyone tell me is it cheaper to buy and fit an intercooler or do we con
the
90hp ECU into thinking it is 110??? No apologies for keeping it
simple(KISS).
Happy Motoring
Wally.

 

Sorry Guys -- I started this but, it is getting awfully complicated. So
far, I buy/fit an intercooler and my 90 becomes a 110?
This is less expensive than conning the ECU???? Then, being
torque/power-mad, I go for the in-line box or the ECU gets it?? Surely, the
over-heating problems which exist on the Hdi units are due to coolant loss
in hoses or radiator blockages?? Ain`t thermodynamics fun but, not as much
as the internet.
Keep it COOL,
Wally.

So, do I buy/fit the intercooler and my 90 becomes a 110? Perhaps,for less
money than an in-line box or messing about with the ECU? Surely, the

So 90 + intercooler = 110 at what cost? Seems maybe a better bet than
ECU trickery. Anyone done it?

No, the ECU software on the HDI 110 is different to the HDI 90

putting in the intercooler (which my HDI 90 has anyway ?! ) will not turn
your car into a hdi 110

 

Looks like I wasted my time typing that message if you arn't even going to
read it

FITTING AN INTERCOOLER DOES NOT TURN A HDI90 INTO A HDI110 THERE ARE
SOFTWARE DIFFERENCES

Fitting an intercooler will give you consistant performance at full throttle
in warm to hot weather

 

Hello,

Interresting, as I saw a HDI90 having none... Oh, BTW, and don't think I
wanna laugh of you, haven't you made the confusion with the aircon ?

The HDi 90 shouldn't have any intercooler, moreover its engine code is DW10T
(DW series, 2.0l, Turbo) - 110HP code is DW10TE (DW series, 2.0l T,
intercooler).

 

if you fit and intercooler PLUS new ecu you'll get a 110. Cost? well i'm
guessing a bit but an ECU is £500 and an intercooler ATLEAST £400.

 

Hello Luke,

regularly
It is, under certain conditions.

I guess the reason is slightly different. The HDi (as any Commonrail engine)
is built around a hi-pressure pump. This pump is made of 3 pistons, two of
them always on, the third one having a clutch. It is interesting to see that
this third piston gives you access to the highest pressures.
It is deactivated under some conditions, one of them being a fuel temp above
70°C. In this case, you'll stay with low pressure range (800 bars, perhaps),
and the ECU will cope with that.
This temp of 70° may seem high, but could be reached with high pressures
(sports driving).
This is my explaination, nothing to see with fuel economy or whatsoever...
