fitted injectors and coded. power feels laggy now? :(

[Dr HMS Derv Destroyer]

hi all, i have a dci 80, the old injectors are fucked, so iv opted to get dci 100 injectors.

fitted them today, towed the car down to SRS renault , and gave them the disc to code all four injectors via clip.

now, when i had the old 80 injectors, my exhaust sounded allot louder and boost was Alot more punchy.

i have neither of those now, exhuast sounds like i have put the cat back on and the boost feels like someone is puffing air into the engine rather than forcing.

whats wrong? :S

 

[Tony Hunter]

I would say wrong injectors. I know it's an obvious one.

 

[Dr HMS Derv Destroyer]

theres no reall difference across the range bettween 65/80/100. just power out put as the 80/100 injectors have better internals. it coded to the ecu alright. fuel pressures all look normal, and it idle perfectly. just hasnt got the gutts behind it ::S

unless something clip wise went tits up and ' down powered ' it all .........

 

[Tony Hunter]

Like limp mode, but with no lights.

 

[Dr HMS Derv Destroyer]

almost like limp mode but you can actaull take it to the 5k limmiter.

no lights no nothing to indicate a hickup on engine managment side

 

[mi16chris]

Ur car will need remapped to make it work , there the wrong injectors for the ecu mate

 

[Dr HMS Derv Destroyer]

an excuse for more horses then cannot complain about mpg tho. seen 82mpg on the display today LOL

 

[mi16chris]

an excuse for more horses then cannot complain about mpg tho. seen 82mpg on the display today LOL

It wont be right tho as ur ecu thinks it has different injectors fitted then what it dose so it will not know how much fuel is going in, u will have to get a custom map done on it

 

[Dr HMS Derv Destroyer]

will book it in for a map tommorow. cant have it anylonger feeling like a snail.

cannot remember the max bhp they can map it to tho as if i remember the clutch cant hold much more after 200 torque something other

edit, the ecu must know they are 100 injectors, the codes are for correcting flow rates?

iv read up and the only difference is the 80 and 100 injectors are 15% more fuel efficiant ( sp )

flow rates have been coded in via the disk that has to be ran on a clip computer.


or am i getting this all wrong?

 

[MicKPM]

The C2i codes are only for fine control also not full control so unlikely to be this. I assume clip is showing that the injector control is functioning correctly and that they're not needing any running in cycle (as the Clio III K9K does).

 

[MG cup]

I can't see just the injectors being the only difference between the 65/80/100. That's a 45bhp difference from just injectors? There must be more boost, fuel pressure or both to achieve that figures. I would say at least you need it re-mapped or the 85/100 data flashed onto yours.

You say there more efficient between the variants. Are they all common rail injectors?

 

[Dr HMS Derv Destroyer]

running in cycle, ? the guy did something that made the revs go up and down for 10 mins.

i pressume thats a test mode....


i know he said everything is running a correct pressure and firing at the right time. all injection control is corect and paramounts ( sp ) set to suit.

i cant really explain what i had seen on the screen as is bloody confusing. all i know is he had all 4 injectors up on screen, fuel pump and rail, and some cotrol codex thingy. it ran like a bag of spanners on first fire up, loads of white smoke. then settled itself to around 800-900 rpm idle speed

yeah, all common rails. mines an dci 80. only two other differences bettween my 80 and a 100 is intercooler and fuel pump. mines an delphi and 100 have a bocsh pump

 

[MG cup]

So I would say your going to need some mapping. I have never worked on a car/van/bus or truck with two manufacturers doing the fuel system. I think there is your problem. You have Bosch injectors running on a Delphi fuel system?

 

[Dr HMS Derv Destroyer]

spoke to a mapping place, im being shuved in this afternoon. gyuy said the fuel to boost ratio isnt right.

thats if i can get it to start now ffs

 

[clio37]

It will be interesting to see what bhp you come out with in the end?!
When I was on rover forum the popular diesel mod was putting sdi injectors into your regular diesel im told it would bring around 20bhp then remapped 30+ so lets see how it goes on the clio.

 

[Scrooge]

If it was running and no lights I would say the injectors are fine, a map should see you right. If its just a dodgy fuel/air mix due to the higher flow rate of the 100 injectors the map should solve that.

 

[MartinR]

Will be good to see the outcome. At least it works now get it on the rollers in march now...

 

[Dr HMS Derv Destroyer]

the guy is having a right laugh, he siad who ever played with the map before has put it on a one way ticket to destruction.

having to have the map set back to basics before tweaking it. im only running 0.7 boost atm down to the fuel/air ratio
normal boost is around 1bar and remapped should be a tad more.

as for a print out , printer isnt working -.- hopefully will have some results before tonight. and i shall stick it on the RR at the next west midlands meet

does anyone know how to stop a cam end leak? i have oil dripping down the side of the block

 

[Dr HMS Derv Destroyer]

mega problem, the ecu refuses to clear the old map or upload a new map. so im stuck with this map

does this mean i have to have an new ecu then?

 

[Scrooge]

Pm chip for some advice mate.

Do you know what he is using to load the map?

 

[Dr HMS Derv Destroyer]

dynodata something or other. it will go to upload the map and then is says lost connection to ecu.

same for trying to clear the map.

this car will be the f**king death of me. its driving me fuxking nuts!!

 

[Dr HMS Derv Destroyer]

fault codes found ! maf sensor inactive.
fuel rail pressure switch not functioning.
egr valve circuit open.

how?!! the car is running on the rollers. no black smoke or any other worrying things.

i wounder if SRS did something with the clip computer :s

 

[MG cup]

MAF inactive, thats why its flat as. EGR circuit open usually means unplugged when it flashes that code.

Did you sort it out?

 

[Dr HMS Derv Destroyer]

sorted. now big power gain map. just adapted to suit dci 100 injectors. so fairly standard again.

fault codes was previously stored and not cleared.

runs sweet now, lovely diesel injector tapping lol

and found a small air leak on fuel line which by the sound of the engine , it made something tap louder

been told to make a propee decat pipe up, and pikey hollowing a normal cat caulses flow issues.

happy days !

 

[Gray]

So what did you do to fix this issue? :S

Flashed a standard DCi 100 map on the ecu?

 

[Dr HMS Derv Destroyer]

he couldny orginally get the ecu to play ball. changed to the back up mapping computer and uploaded the dci 100 mapp and then tunned it slightly to run better. no big power remap, just a standard'ish tweaked map.

spent hours try to get the ecu to respond.

got there in the end. lesson learnt, fitting 100 injectors and coding them is allot different to swappng the injectors around on a 65 to an 80.

i feel such an idiot thinking it was simple. just caulsed myself one big massive head ache and a empty pocket

still have two issues, glow plug control unit is constantly having a live perminant fault code hissy fit and i have a suspected piston slap on cylinder 4 ( gear box side ) aparently could be caulsed by something cauled ' washed ' from a overfueling injector

 

[Scrooge]

I can't see how the the injectors stopped the ecu from playing ball though. There's no reason for it.

Glad you it somewhere with it though

 

[Dr HMS Derv Destroyer]

ecu didnt like the codes that we gave it. didnt like the code disk thar the lads at renault programmed via clip.

i feel sorry for mark that went out his way to sort it for me.

leaving it alone now.

You went from non coded injectors to coded with two different manufacturers of components in your fuel system. I don't see how that is working, Bosch injectors are completely different to Delphi?

 

[Dr HMS Derv Destroyer]

same design, both solinoid driven injectors. peirzo ( style injection )

its running perfect now, havent had any problems since yet.

future reference to anyome that fits dci 80 k9k 702 engines with dci 100 injectors, dont do it lol

 

[Dr HMS Derv Destroyer]

f**k sake had enough.

car will not start in the morning or after being sat for a while ( hour or two )

engine tries to fire but cant. spray a little easy start into the intake, it'll fire up and run perfect, drive around switch off , it'll start again if done with in 10 mins.

i give up! :'( whats wrong now?

the fuel system isnt drawing in air as the clear pipes have f**k all bubbles !

 

[Beasley Clio182]

Did you do anything in regards to fuel pump? just guessing as i cant give a diag with out looking at the car but it sounds like either fuels running back or not pulling through correctly ? Is there any difference in fuel pumps from the 80 to 100 dci?

 

[Dr HMS Derv Destroyer]

as far as im aware and looking on cliodci.net the pumps are the same pressures but differnt maufacturesn

does 65kw mean 80hp? just to make Sure i didnt by 80's in the end

 

[MG cup]

Were they new injectors fitted? Bosch right?

 

[RSTuning]

the 80's and 100's run different rail pressure and duration

 

[Beasley Clio182]

this ^^^ for all your hassle id seriously consider banging a old set of 80's in and getting standard map !

 

[Dr HMS Derv Destroyer]

done it today, set of 80's from my spare parts engine, had my ecu flashed back ( guy came out with the computer with my original map on and re loaded it ) coded injectors. will not run at all, getting no compression, engine is way to easy to turn over.

its had a ticking/ knocking noise for the last 7000 miles, which i though was injectors or solid bucket valve train.

guess i have the symptoms of ' bore wash '


seeing as in the spec book says dci engine should give or take only burn off 1L per 6000 miles. mines doing that every 2k !

Shouldnt really suffer bore wash though , that's either the piston rings are knackered or the cars been over fuelling like i don't know what !! how do you know its bore wash ?

If theres no compression you've got bigger issues that bore wash , sounds to me the knocking you mention maybe more a problem , have you done a compression test to see which cylinder is down on comp?

If its cylinder 1 (gearbox end bloody french) then id suggest you have bigger issues mate to do with the tapping/knocking , do a proper comp test and see !

 

[MG cup]

Smell the oil first for fuel. Give it a whiff of easy start if oils okay then if no joy put some oil down the bores, let it settle and try a compression test again.
