Nope! Only Cups and only if they -dont- have air-con!! I phoned John @ R-Sport, asking for an R-Sport ECU for a Cup with a/c (thinking if they say it fits and a/c Cup, then there might be a hope for a std 172. Previously, people have said that the R-Sport ECU wont work on a 172 becuase of all...

Thanks Tom So how are Simon172s and the R-Sport ECU different to the Group N one? And any ideas on the 3 listed, in terms of spec?

Does anyone have a good knowledge of the spec of these ECUs, what they alter, and where they are sourced from, just that... .... I recall Simon172 fitting one on his Mk1 172 and taking it off because it ran like a dog afterwards ... I believe they are sourced from RenaultSport in Dieppe...

If you dont mind me asking, what are we talking here? 2k, 3k, 4k? I presume you should recoup some of that when you offer the kit next year?

Been running a HP IK on my mk2 172 for 4000 miles now, and the fuelling is fine.

Hows the throttle body conversion going?! Any news on when itll be ready?

*LOL* Well, the old (std) pads lasted a mere 7k miles and about 5 track days! The PF carbon ones are much harder and are supposed to last much longer. But then again, £120 for pads every 18 months isnt too bad if you spend a fair amount of time on-track.

Ive got Performance Friction Carbon Metallic pads on my Mk2 172 and theyve superb! A bit noisey but they dont fade, even on track days. Pads are about £120.

Shame R-Sports mods dont work on a normal 172 and they have no plans to adapt the Cup ECU for a 172 either :@ According to R-Sport, the engine in the Cup is different so the inlet manifold and ECU upgrades dont work on a normal 172.

paul172 has a polished engine top, just as you described Si....a mate of his did it for him

Front camber mods improve turn in. Rear camber mods dramatically improve the stability of the rear and removes the twitchiness

Im running a degree of -ve on the front and about 1.5 degrees on the rear....

Hey Roamer - any updates?

Ask Colin - hes got a Clio Racer...

If the R-Sport car was the one with the daft stick-on bonnet vent, then it wasnt that quick. I remember from Donningon that it was behind me a few times and certainly didnt have enough extra power to out pace me on the straights.

Phoned R-Sport today, who werent able to comment as the main contact wasnt in (Jonathon). I asked if their ECU worked on a Cup with AC - surely the first tell-tale sign that it would also work on a normal 172? Well see what they say tomorrow...

I take your point.... I would appear to have a reasonably quick 172 - it put out 172bhp on BB Tunings RR and is quick enough on track against other 172s. Im not convinced about the Unichip as its an add on and, AFAIK, relies on the knowledge of the fitter to set it up properly. Ive spoken to a...

So, the question must be, does the R-Sport ECU work on a Cup with air-con? If it doesnt then the incompatibility theory is stronger. If it does however, there may be hope for us 172 owners!

According to an earlier post elsewhere, the Cup ECU has a few less functions than the 172 one, hence the incompatibility. Or, it could just be a cunning plan to charge more for the 172 one!!

Ive noticed that on 03 cars the drivers door is now de-locked! Nice!

what tyres are you running? 205/40x17s? If so, then they are larger in rolling diameter than the std setup, hence the performance difference...

The Pro kit is 25% stiffer, the Sportline 35% stiffer. Ive got the Pro kit on my Mk2 172 with a load of geometry mods and the handling is sublime :-)

Anyone have any news on when itll be available for the 172 (not Cup)? I didnt get a chance to speak to R-Sport @ Donnington, but Im hoping itll be out soon, otherwise itll have to be a save-up-and-go-for-Roamers-throttle-bodies option!

I was right behind the guy as he rolled it - all I saw was a cloud of smoke with a spinning Clio Cup in it, then it hit the gravel, flipped and rolled onto its roof. Myself and another Cup driver stopped but the Jag safety car was there in double quick time and the guy got out and looked OK...

Or, try 17s with 225/35x17s

See ya there! Pop over and say hello! You wont miss my car - itll be the one with the Mk2 V6 spoiler ;)

BUMP!!!

Thanks for the feedback Nick. So will this mod fit a Mk2 172?

Well, my OE pads lasted 7500 miles and about 5 track days! Ive since replaced them with Performance Friction Carbon Metallic pads (Clio Cup racer spec) which are superb.....Ill test them on the track at Donnington next week :-)

Removed the Renault Sport badges on the left from my 172 but as bambam says, removing the Clio one will involve a trip to the sprayers! Shame.
