If I were the OP I'd be picking the car up and taking it to one of the many specialists on here and having it sorted.

they told me you were invoicing them danny for 2 hours labour so they are charging me £90 ,
We were never quick tot ake the money, and we did do a before run and it was a messy curve.
As a tuner, we are tasked with a job, which we undertake. Nick came down, test drove the car and took it away, I asked if he was happy. He then brought it back as then decided he wasnt happy, and I have offered to get to the bottom of it.
Other tuners would of said: Oh your the guy thats paid already, see ya later...
Also, by 100k car cars he doesent mean lambos, he means the race adn track cars we looks after that are worth 100k, but experienced racing teams that trust us for our tuning work. And that does say something for a company.
My aim is to get the car running spot on, and to look for advice on here from people, like Danny, who are in the know. The cam timing was out by about 30*, have a lookm previous for pics.
If we have been given a dead lump to tune, I'll tune it. If you want me to strip it down, inspect it and certify that this engine is ready to be tuned, I'll do that, but it wont be for free.
We have seen 155bhp from other clios (like Andy Knights circuit car 172 that we tune) and then with ECU it made just over 180bhp. (everythign else OEM)
If people like Danny (who is respeceted on here) and knows clios inside and out scratches his head, where does that leave us?
The car is being done but unfortunately we do have comitments and support contacts for race teams that must be adhered to. When Nick wants to coem down at 8pm and take bits off I'm there. Find somewhere else that accomadates all hours of the day to get things sorted....
Typical forums.

That is correct.
ITB'd MK1
true enough. sounded like you'd paid already
-confirm lift@tdc (don't assume it's correct for the cams just cos the Renault timing markers have been verified--cams could be fitted wrong way round---it happens)?
-----I did suggest this but assured by Danny and others that the stock timing marks are spot on for these cams. Its not how usually do it for Kents etc on Zetecs but thats Zetecs
-base ignition angle correct?
---Will check again but yes, using my standard clio basemap
-fuel pressure correct?
Yep
-ecu/injectors/coil functioning correct
Yep
Exaclty my point.
How far can we go? Should we check that people havent ran fuel lines through the backbox? Or the hubnuts are tight before we map it? Tghe list could be endless. Yes, I can confirm an engines health, but I would fully strip it and blueprint it to be 100%, and that isnt 'cheap'
Matt
We got a 155bhp engine up to 185bhp..... now we are fixing bad cam timing done by another company....
errrrr pot calling kettle black
lolhow many have you paid to practise??
still....least youve seen sense now.
It was 155bhp and we got it up to 185bhp....
it did lose power when the cam timing was done !!! lost 50bhp , it was 155bhp when it first went in , 188 when it came out of there running sh1t, now it is 130bhp after having the cam timing done
FLOL! I was right then, it has lost 25bhp since it first went in.
yeah !! £2100 well spent IMO :rasp:
lol Nick with all that positive outlook I cant wait to sort it for you.... ???
Mine was 158bhp, and went to 204bhp
So the low starting thing doesnt sound correct, unless its a bad egg?
Oh and birchdown have been there well past closing for me, so other people do do it Its great that you do as well!

Its great that you do as well! the way i see it is the car went in there running fine to me , other wise it wouldnt of been dropped of there in the first place , as i was spending £2100 on bodies so wouldn't skimp out on getting a problem sorted in the first place and as the car was going to be purely a track car i definately wouldnt of dropped it of there if i knew the cam timing was out , there is a renault specialist near me who could of done it for cheap , 3 months on the car is still running sh1t and still stuck at m tech , dont get me wrong matt seems like a top lad and has definately tried his best to sort the car , i think he just has way to much work booked in and my car keeps sitting there at the back of a quew as he needs to get the unpaid job's done before mine !!! you can understand my frustration matt as im sure you would be the same if you were in my boots ,

Nick, no I do understand, like I said will get it 'done' for friday. I'm going to pop it back on the dyno tomorrow and hopefully we can do some tests and get it either finished and good or at least diagnosed.
Cheers

lift number 1 @ btm
But would it still show good even compression then?
ITB'd MK1
The compression is too good for it to be an engine weakness. I've told Matt what i believe it to be after doing some comparisons, have to see what he comes up with
The way i see it after reading between all this squabling
Car went in with 155bhp.
Car fitted with bodies and mapped with incorrect timing makes 184bhp.
Cam timing correct, but mapping not changed to suit correct timing, 130bhp.
Is this not just a simple case of a remap on the correct timing? whats the big problem?

it's good to see some of the other companies/tuners etc.. helping out another company tbh
also as said before matt is definitely going one step further to try and rectify the issues (just like a few of the other companies on here would do aswell) so fair play
hope you get it all sorted on friday, for both of your sakes and sanity

Well practically speaking power doesnt just dissapear does it.
Assuming the dyno is reading as it should, and assuming the fuel and ignition system is functioning properly, then its (basically) down to cylinder sealing, volume of air per cylinder, fuelling value and ignition advance value. Obviously there can be one or more contributary to each of these.
Volume of air can be tested with a flow meter whilst doing a power run. If this is low then you'd want to be checking lift at tdc, valve lift, throttle angle, basically anything and everything that contributes to cylinder filling, and AS crucially thats its the same per cylinder.
You can also do a blow-by test whilst doing a power run, to show loss through the rings when under full load/power conditions.
Fuelling is obvious as that will be logged on the dyno, and is specific to the above.
Ignititon lead, you can check ACTUAL advance manually whilst doing a power run to confirm it is what it the ecu is saying it is (I cant remember what ecu it was, but a friend of mine had a similar issue, it turned out to be the crank angle sensor was wired the wrong way round, and since the signal was "upside down" at a certain rpm, say 3500rpm, the ignition advance would just revert to a static 15degs!)
Oh, the exhaust isnt blocked is it?!

Would it not be better to pick up the phone and ask him personally instead of waiting for him to come on line, especially if you're after your car back farily soonish.
Just a thought, and not meaning to step on anyones toes in anyway. but after all is cured and it turns out to be down to a previous fault and nothing to do with the ITB convesion, will it still be FOC? Bl**dy good service if it is in my books.
People need to stop spamming this thread as well , and stating the obvious of phoning them , im not stupid and do ring them all the time to see how they are getting on with it , i asked how they were getting on with it as they said they were looking at it today and i never had chance to phone them , as i work in a very low signal area !!!
not at 7 o clock it wouldn't no i dont really enjoy listening to a ringing tone knowing the phone isnt going to get answered , as they are only open till 5 :S
I think you should remove your itbs etc and let the poor lad go to k-tec with the money he's paid you. His car should be your top priority in getting running it right, youve fobbed him off for 3 months with excuses.
sounds good to me , if it isn't running around the 200 when it comes out of there i think thats what i would want to do ,
Ive fobbed him off for 3 months with excuses? So far I have recitifed bad cam timing, and now remapping the entire thing for free.
After having a look at it today, I am starting compeltly from scratch with the map down to inital timing offsets etc. Have been using a basemap for one i carried out on a similar (172) car and I think a clean slate is what the car needs.
Updates to follow... either way its now in the pre-mapping bay so its the next one to be done....
