External waste gate on tce!?!

[Dr HMS Derv Destroyer]

You know how short men are often angry and shouty?

Same with people who have small engines.


lol

ay! take that comment and change it abit. i aint complaining about my small engined dci. 1.5 isnt massivly big lol

also to my previous comment about head work on a turbo'd engine... mine seems to pull allot better after port polishing the k9k head on mine. wether its down to the now more free flow path or one of my other mods has made a difference i can see

 

[Westytce]

What a weird thread. OP has an attitude problem.

Harsh... to be fair I'm looking for advice on the project not opinions of why I shouldn't do it, It's a Clio this is Clio sport, and you seem to encourage and publicly offend a member, quality moderating.

 

[Westytce]

Just buy an old Valver or an MX-poverty then, they'll be far better drives than what you'll end up with fella.

Oh and don't worry about CS getting hangbags over reliability, pretty sure everyone's had at least 1 issue with their french tin

The saxo is still working like new on 145k... I don't want to buy another car thanks.

Watch your attitude!!!:rasp:

 

[Dr HMS Derv Destroyer]

lol i see what you did there

 

[Westytce]

lol i see what you did there

Did see anything gaffa....


Maybe I should save the money and not give it people like ktec... Imagine if we all did that....

 

[Dr HMS Derv Destroyer]

i dunno really, never been ktec for my car so cant comment on it

 

[DannyR]

This thread is lowering the the average IQ score of this site dramatically.

OP is clearly trolling as nobody could be this naive/stupid.

 

[Westytce]

Again harsh... Nice to meet hear from you to, your very welcoming. Its good to hear peoples views. Its not your average thing to do so a good thred for others to read if people can keep it constructive....

 

[MartinR]

This still going?

 

[DannyR]

Everything has been said over and over.

Please re read the thread and take in everything Chip says.

 

[scotty2hotty81]

This still going?

Suprised it hasn't been locked (IMHO, tbh, Flol) for the op

 

[Westytce]

It's moved on a fair bi from the waste gate so maybe locker her up and I can start a new thred if I want advice on other aspects.

 

[John Gordon]

If its a low blow turbo why are you fitting a "large fm intercooler"? That's counter productive.

 

[Goodj]

OP, have you searched on here for "bucket mod".

SRS, it'll sort out a whole load of your intake issues in one go

 

[Dr HMS Derv Destroyer]

has he even got space in the mk3 bay to do the bucket mod?

last time i had a look at a mates mk3 bay, its was full of usless plastic s**t taking up space

 

[Westytce]

Love blue peter, did he get a badge for his efforts. :star: That reminds me, loo rolls need to go on the shopping list!

The injectors arrived today.

Please quantify larger intercooler being counter productive. Larger turbo, larger intercooler, it wont be a monster intercooler.

 

[Chip-mk1]

Despite the fact that in theory a larger intercooler will mean a delayed response, in practice Ive never found that to be noticeably the case.

This is the size of intercooler I use on my sierra for example without any appreciable difference over the standard small one:

 

[Dr HMS Derv Destroyer]

sierra? looks abit more like a escort :S or am i missing something

 

[Chip-mk1]

you are missing the fact I said "this is the size of intercooler I use" rather than "this is a picture of my car" I dont have a picture of mine with the bumper off so googled up something else with the same size intercooler to post instead.

sorry

back on subject, thats almost the size cooler my dci runs, havent seen any lag difference bettween the small sized dci cooler to the aftermarket one

 

[Westytce]

Pipe diameter makes a difference doesn't it?!?

 

[Chip-mk1]

Pipe size makes a difference doesn't it?!?

In theory yes, in practice very unlikely to in my experience.

 

[Dr HMS Derv Destroyer]

Well if you think of it this way , putting silly small sized pipes on will caulse to much pressure.
Which in turn would blow out of the weak points
But only a muppet would get that wrong.

No, putting too small pipes on will result in a drop in flow, it shouldnt really make a significant change to pressure, as the turbo actuator will still be controlling that anyway, you might see a couple of psi more if the reference for the actuator is right near the manifold, but its not goign to triple the pressure or anything no matter how small you go really.

 

[Dr HMS Derv Destroyer]

I see, so if we are saying it like that, will it be more efficiant to run smaller pipes or basicly naff all difference from normal sized and small sized internal diametre pipes?

 

[Chip-mk1]

Naff all difference IME from slightly smaller pipes in terms of response.

Obviously you wouldnt want to go totally ridiculous like 3" on a 100bhp engine, but within reason going a bit bigger than optimum is fine so if in doubt then aim for a generous sized pipe.

 

[Westytce]

2" pipes are going on

 

[Westytce]

Mr chip,

These injectors.... best to fit when car is being mapped, not before, do you concur?

 

[Chip-mk1]

Mr chip,

These injectors.... best to fit when car is being mapped, not before, do you concur?

Yes you should fit them just as its about to be mapped, if you drive around with injectors bigger than what you are mapped for you will end up running rich as a result.

 

[Westytce]

Recomend anyone for mapping? Do you Rate ketc at all?

Here a mapping question what exactly do they do to map it, I understand there are ecu settings for spark fuel etc, is this all that is involved, changing these or what more is there to it....

 

[Chip-mk1]

There probably arent many people with even a partially built DAMOS file for that engine, so your choices for mapping on the standard ECU are going to be pretty limited.

RS Tuning in Leeds are probably the best of the renault tuners for that sort of thing, assuming you catch Paul in the right mood, he's a clever bloke who I fundamentally have a lot of respect for but seems to have good and bad days a bit, lol

 

[Chip-mk1]

With regards to the actual mapping, the biggest issue with standard ECU's these days is all the imposed limit tables, the fulling and ignition is actually the easy bit, its finding and altering all the limit tables to actually allow it to then run those values that is the harder part.
The actual "mapping" is a very small part of the job, you spend most of your time attempting to work out what the standard map is actually doing in the first place, there are literally hundreds of tables and renault dont provide you with details of where they are on the chip or what they do.

Thats why so many aftermarket maps on standard ECUs have shortfalls in them, its because the person doing it hasnt worked out all the tables they need to use first.

 

[Westytce]

In short what im hearing then is new management is better as it's a blank canvas with no hidden problems.... Ktec have said new ecu is unable to run all dash functions..... Thoughts on this?!

Rs tuning background is IT iirc.

 

[Westytce]

This info will mean more to you than me.... What does this code mean?

HW=Siemens
SW=111RD348CA - 1111111111
CHK=Siemens SIM32
Read and Write with CMD

The twingo has the tce engine also these have been mapped.Same engine same software?!?

Aftermarket mananagement is designed to be easy to map, so will be far simpler to do, you can probably piggyback your existing one so it still does dash functions etc, but as I assume your car has an ETB its not as simple as with thigns like a phase 1 172 turbo like mine.

That long code is just the revision of software, it may be very similar DAMOS to the twingo, or it might have some differences, I am afraid I dont know as I have never got involved in either, I really do dislike mapping standard management so tend to go for aftermarket wherever possible unless its something where DAMOS files are readily available (the thing that describes the data on the map so you know what to edit), unless you are in business doing 100s of the same car, its not worth the effort, and everything I get invovled with tends to be more exotic one off builds so aftermarket makes more sense.

I woudl think that as what you are doing is relatively routine, just a bigger turbo and some minor differences, that Paul will be able to do it reasonably well on the standard ECU.

 

[Westytce]

Thanks chip really helpful, my car was a demo car also so it has all the extras, cruise control, speed limiter, aircon with climate control, blue tooth, steering wheel controls, heated electric package etc etc, so lot of demand on the electrical side of things,

Does the ecu manage any of that... I would think the cruise cont, speed limiter it does...

I'll give Paul a call and see whats what,

Ive thought standalone may be best IMO, but I'll let the experts decide what is best and go with that.

Ktec did say that they would need the car for a fair few hours and won't know what's best until they start mapping it as they havnt done anything as far as new turbos on tce before... They have a map for filter and exhaust apparently a 130bhp map but that's all.... I don't care about bhp but do want it running well and healthy rather than just done and kicked back out if you know where I'm coming from....

I'm happy to pay for dino time, but ad you say it could be knowledge that's the limiting factor....

 

[Chip-mk1]

all the engine related bits like cruise control the ecu will do, bluetooth etc though will be the radio bits and the aircon etc will be a seperate control unit

 

[Westytce]

Sagem3000 or sirus 32... Some debate on that right now.... Can anyone clarify?n
