Update:
Before heading up to RS Tuning, I thought id do a bit of fiddling and see if I could improve things.
So I thought Id move the air temp sensor. Normally these are mounted into the air filter, but as Im not running a filter with a back plate and wont be for a while, I thought id try a different route so I drilled into a trumpet and mounted the air temp sensor direct, so it can read the exact temperature of the air as it enters the head:
Excuse the cable tie, this was a temperary measure to see if it would work:
This, and the new lambda probes (thanks again Maynard!) had an interesting effect on the map, it made the car run rich at the bottom end and lean at the top, so Paul needed to do some changes, but I left with a much smoother looking map:
The power curve is getting to the point where you can near enough draw it with a ruler(apart from the usual dip where the car comes on cam), and the low end torque has improved, as well as the car pulling harder when going past 5000 rpm. It has also improved the fuel economy too, to the point of I was getting a genuine 43 mpg, which shows with the right setup a itb'd car can equal a standard inlet car
Next on the cards will be some further testing of this setup, until my next 'stage' (as I call it lol) will be ready for testing.
I need to work the filter a bit better, as it is still strangling power :
Paul is pretty happy with how the map is at the moment, next stage is to improve the throttle response, which is what the next stage will do, as well as hopfully netting a few more horses.
Once again I cannot say thank you enough to Paul at RS Tuning, he a leg-end and his mapping skills are mind blowing!

You could market that ECU for a fair wedge with that spec (sorry)
FLOL at drilling into the trumpet - why not

Just read a lot of this thread and have to say I am very impressed. The detail you have given is great, I feel like I could do this conversion myself just on what you have written here. Just have to decide if I am/can afford to keep the clio. One question tho, as I don't have a cable throttle would I need to covert it? Also, was there any specialist equipment needed (apart from for the mapping)?
Cheers,
Will

Hi will,
Thank you very much for your kind words
To be honest, im not quite sure on the ph2 models. I havent looked at the tps, as long as they are the same as the PH1, then I cant see you will need anything more than a ph1 throttle cable, the securing clips and a ph1 throttle pedal.
Im pretty sure Paul wouldnt have any issues mapping a ph2 ECU, as as far as im aware they operate the same as the PH1's.
You will loose your speed limiter and cruise control if you have them, but apart from that everything else should work.
Mine still needs more fine tuning, so id suggest everyone holding off till iv developed mine so its as good as it can be, so I can make it as easy as possible for everyone to carry out the conversion

very, very nice car!!!
Hi Russ, I've been watching this thread for a while, great work! It set me thinking, and I am hoping to carry out a similar project on my high mileage phase 1 172. Mine has 136000 on at the moment, but I did do a top end overhaul at about 85000, when the auxiliary belt destroyed itself and wrapped around the cam belt with the obvious results!
Anyhoo...
I'm hoping to beat you on the price. I've just bought a set of throttle bodies from a Yammie R1 for £60 on e-bay. Until I get them I have no idea whether they will be suitable, but there are a lot of guys rallying cars with bike throttle bodies these days, so I'll give it a go. I might even start my own thread!
Cheers,
Neil

Lol cheers Neil, though im afriad you wont beat me on price, if I told you exacly how much it cost me, you would fall off your chair!
I was lucky to get a good deal on the Jenveys, which helped.
Definately get your own thread up and running though!
The reason why I havent bothered with bike bodies, is with the Jenveys its a fairly bolt on conversion, only a little fabrication of the manifold was needed, and the tps hooking up - some bodies can cause some more hassle, such as injectors and rails, I have used all the standard equipment from sensors to even the fuel rail.
With bike bodies you also find they never go as large as 48mm, and also they tend to have a very small amount of throttle opening, meaning the throttle can be a bit snappy, and if like me you wish to run the standard ECU I feel you will have real problems with sharp throttle openings,(this cannot be mapped out) as the sharp intake of air will cause the MAP sensor to lag,(this will cause the car to missfire/bog down at low revs and sharp throttle openings) I find this slightly even with mine, but I have a cracking idea to solve it, with aftermarket ECU's they dont run a MAP sensor, so if your looking at an aftermarket ECU then bike bodies will work out as a good conversion.
Hope that helps

Hi, new to the club and clio,s, like what your doing, i have picked up a x reg 172 i also happen to have a set of jenveys and an emerald ecu from my previous car. My worry is what problems i might encounter elsewhere if i was to remove the existing ecu, any advise? cheers
Hi and welcome mate
You need to leave the existing ECU in place, to run the dash (rev counter, speedo etc) but splice out the wiring for the engine and run that to the emerald. It is a fiddly job, but not super difficult, have a read through a few other itb threads as mine is unique in how my Jenveys are fitted, it also depends on what type of Jenverys you have, I have DCOE style which is very uncommon.

Its just put in a respectable time down at pod... i'll leave him to update..
Evo 5 RS
sweetness! Guesstimate at 14.3
over 100mph?
So far its ran a terminal of 96 iirc. its not in the 13's. ive told him hes not coming home until he has lol.
I should say that its in full road trim. 1/2 tank of fuel, full interior, spare, and tool kit. on road tyres, which are t1-r's iirc.
Evo 5 RS
lol

daaamn I was close haha. great results mate considering no weight removal

cheers mate . im currantly looking into getting a standard air on mine and modding it a bit to try and stop all the hotair getting sucked in and hopefully if all goes well, when i go back in october for the rwyb night racing ill get in the high 14`s (wishfull thinking lol).
hope to see you there.
