Another quick one, and I'll leave you be!!

Should the priming bulb always be rock hard (once the car has run a bit)?? If not is this a problem??

In the Honda handbook/manual, it says that if you do prime the filter, you should run the car at 1.5k revs for 30 seconds to get rid of any air, is this right??

Again, help/advice much appreciated!

Hi Carl, thats right about running it 1.5k revs after. Mine is not rock hard after running it, just when you pump it a few times to pressure up after bleeding/replacing the filter.

Hi guys, just booked my honda accord 2.2 ICTDI into main honda dealer in dublin Ireland for a fuel filter change next thursday.
Hope this sorts my problem aswell even though the filter was changed 10000 miles ago with a malhe or kneckt fuel filter( german made)
Willl let you know how i get on. Also have not been able to use the engines full potential ( chip express unit fitted)

Even with a new filter, no box will give you the full potential of the engine. what you need is a proper remap.

WTF is that and why don't you like you car? Aftermarket filters? Engine chips?


If your car was a dog the RSPCA would have had it away by now :lol:

I would avoid using the power up unit all they do is ramp up the fuel pressure, its a crude way to develope power and takes no account of any other engine variables. I would recommend a proper remap from a reputable tuner like Premiertuning via Fahad and at that cost it makes sense.

To be fair the same could be said of any generic map that is installed on a car. You will never get the full potential of any car unless you have a proper rolling rd remap done as all cars behave slightly differently and have slightly different power outputs despite being identical engines.

I am not knocking generic remaps as they are safer than most of the tuning boxes that are available on Ebay etc but you can get some that are car specific and tested to death on the cars that they are designed for Roverron for example. His tuning boxes are hugely popular with Mondeo TDCI drivers and actually give better gains than a bluefin (superchips) remap.

Unfortunately this is a complete myth - and your statement is only partly true.

No factory standard car needs to be rolling road tuned as long as the setting file that has been developed by the tuning company has been developed and perfected on that particular software revision.

If your statement was true, then Honda would be dyno'ing every single car that leaves the production line.

i think you missed my point. i wasn't saying that a standard unmodified car needs to be rolling road tuned as a generic file is more than adequate as any differences between cars would be minimal on a standard car. when you have performance parts like exhaust systems and proper cold air filters and cams etc etc then a rolling rd is more suitable to extract every last bit of power available.

And it is no myth as no 2 cars behave the same due to wear and driving conditions etc, a friend of mine (Gus) owns Alfatune Motorsport who uses a rolling rd and generic files depending on what the customer wants and how much they have to spend (obviously it is quicker to flash an ecu with KWP than do a full rolling rd set up). He rarely see's 2 cars with the same engine putting out identical BHP and Torque figures on his rolling rd. Infact he regularly see's bog standard Mondeo TDCI 130's pushing close to 140 BHP before he even gets a chance to play with the map.

Where comparing apples with oranges here, a car that requires a bespoke RR tune will have significant modifications to warrant such a map. For the most part Accord diesels dont fall into that camp or even close and such a bespoke RR tune would be overkill.

I know. I wasn't saying otherwise. :)

yeah I think we're all saying the same thing, but in different ways.

Not knocking your friends outfit, I'm sure he's a top tuner but if you're putting two cars with the same software revision on a dyno, and both are completely standard - then you should not be developing different setting files for each UNLESS the customer specifically wants something different. And if you are doing this, then you're re-inventing the wheel every single time and then supporting multiple variants of the same software!

And you can't 'start' from a generic file. There is no such thing. There is a standard factory setting, and then a bespoke setting.

That's why the term generic is dangerous. I can only speak for ourselves but we do not deviate from the two stage settings we have developed and are prepared to install on our customer cars. We know both stages we've tuned and are comfortable with what the customer is getting. We didn't develop them in a day either - it's impossible to develop a perfect setting file in a day. You need lots of on the road testing..

Bottom line is if your customer is happy, then you have a good business.

The self adjusting ECU must also play a part no?

Jesus lads what did i start, was only commenting on the problem i have, as i work in the motor trade ( steering and suspension parts co.) and generally i the motor industry for the last twenty years i know all about the pros and cons of non original parts..... years ago non original parts were dodgy.... but nowadays quality has improved. Just a short story for you. While working in a garage we had a 1990 audi 80 in with a o/s/r brake caliper siezed, original part from a audi/ vw dealer was 300 punts irish, sourced non audi part from motor factor in ireland which came from a steering and suspension company in the uk. Removed part from box and discovered it was a girling part with the audi logo ORIGINAL PART. upon further investgating turns out the company supplied audi directly with the same part in a audi marked box, just my experience... cost of part i bought 90 punts.

:lol: don't worry Dermott, cj hates german motors, and the icdti hates non oem filters. It isn't a placebo; it's been proven here many times.

We like our debates here as you can see :D

:lol: I love threads like these it just proves how we petrol owners take reliability as granted.THE only thing we have to do is fill up more at the pumps..THAT is IT!!!!

threads like these bring a massive grin to my face.. poor diesel owners I feel for ya ..awwww

you all start kissing your cars goodnight they may perform better :lol:

Backlash,Backlash,Backlash,Backlash,Backlash :lol: :lol: :lol: :lol: :lol:

CJ, how's about a bit of whiplash :lol:

There's nothing wrong with threads like this - it's a mutual exchange of opinions as far as I'm concerned. It's good to try and dispell some myths as hopefully people learn along the way too - that's how I've been learning.

On the subject of self learning ECU's, all modern ECU's are self learning and adapt to your driving style. But the learning capabilities only extend to within the limits of the hard written map settings. So if you give the ECU new maps, it will only learn within those new constraints.

This is why dyno tuning STANDARD UNMODIFIED road cars on a dyno (most likely in a few hours) is not good. Even if you start from a so called 'generic' tune file and then customise it to that customer car, what you are doing is starting from a mod file and then bespoking it further. But what you're forgetting is that the reason each car even with the same software revision behaves differently could be down to simple things like the quality of fuel in the car at the time, the cleanliness of the filters, the mileage the car has had, the climatic conditions at the time it's on the dyno etc etc. Far too many variables.

If this method was good, then each time your car went to Honda, they should be modifying the software in accordance with the condition of your car at the time.

Dyno tuning has an extremely important place in tuning. It should be used as part of developing a proper setting file for the particular software revision in question, coupled with on the road testing. Dyno tuning of course is the best way to bespoke tune when you have a modified car.

The problem is a lot of companies have invested in dyno's and the world has moved on. People are interested in what their cars are making on the dyno (it's only natural) but in truth what most customers want is good usable and reliable power. If you use a dyno to tune two same cars, but one makes more power than the other on their standard factory runs, what happens when the customer with the lower run maybe services the car or switches to better fuel or was just a victim of bad climatic conditions on the day of the run or the dyno was just set up wrong? There is also then the question of one dyno vs another dyno as no two dyno's give you the same results! It's all down to how the dyno is set up and unfortunately some tuners will deliberately either inflate figures or show lower figures to sell you something..

As i already told you in previous post the honda was booked in a main honda dealer on thursday morning ( yesterday) to have the fuel filter changed . Between handing over the keys and handing them back to me took about 1 hr 10mins. Paid the bill 71.00 euro .... i was expecting it to be more and asked the girl on reception was the problem cured ,yes she said with a big smile,soon took the smile of her face and asked her why i left the car in....so its not cutting out anymore? She didnt know the reason i had left the car in the first place...asked to speak to the mechanic who worked on the car, eventually came out to me.. was the car roadtested i asked, no but i will go out with you now. Of we went and during the drive i asked him did he know the reason the car was left in etc,etc, NO he replied i was just told to replace the filter.
The good news is the car is flying again without cutting out and the also replaced the headlamp clips on a recall.I now must eat humble pie and say thank you to everybody on this topic, i honestly didnt think it would cure the problem just because it was a bosch filter in a honda cardboard box.
THANK YOU THANK YOU THANK YOU.
Im as happy as a pig in s**t :D :D :D :D :D

Give it a few tanks before signing it off. You might experience the odd airlock.

Glad to hear it seems to be ok though!

I was equally amazed at the impittance of a genuine ff. My last Pug, and old T4 vdub transporter would be happy with cotton wool :lol:

If anything it shows what tight tolerances the ICTDI is built to - nothing else will do ;) Glad it's fixed.
