Nik, do you have the Group'N' ecu fitted to your Trophy yet?
What's the verdict?
Which one did you go for – STD or for use with CAI?

182 Group'N' ECU from fastchip

Yep, got it back and fitted it yesterday. I went for the standard group N version as i don't have a viper.
Seems very good, just like the R-Sport i had on my 172.
The first thing you notice is the throttle response is much improved. Try taping the throttle pedal quickly with the standard ecu and theres a lag, so much so that if you tap it quickly the car doesn't rev at all. It's much more instant with the remap.
There is a noticable power / torque improvement at lower revs, the car picks up more quickly below 4.5k, rather than getting bogged down. The power feels more evenly spread across the rev range.
The idle speed is very slightly increased which makes the car better to drive as the car feels less like it wants to stall in stop start traffic, pulling out of junctions etc. and also makes gear changes more slick as the revs dont drop so quickly.
The rev limit is increased to 7800rpm which although i wouldn't make use of daily, has proved useful on track as it gives you more flexibility to leave out that change up to 5th on some medium length straights.
I always said that the 172 should come as standard with the map on the R-sport and i'd say exactly the same with this. Dont expect miracles with loads of extra BHP (if any at all) but it certainly makes the car more responsive and better to to drive.

Sounds great - I've been tempted to get one from fastchip as I had a group'N' ecu on my old Williams.
Did you send them your original ECU or did you loan one? How quick was delivery?

You have to send your ECU away to them, but if you pay a deposit they will send you a loan ECU out first for you to fit while yours is being flashed. I had the use of another car for last week, so i took the opportunity to send it off.
Postage takes 2 or 3 days to get to them (Tip: send it royal mail Airsure rather than International Signed for! as it gets priority service overseas then too) then they reflash and post straight back the same day they recieve it. Return postage takes 2 days.
I posted mine off last Monday, it arrived with them Thursday and got back to me yesterday. I suspect if i had sent it using the post offices Airsure service instead it would have been back to me before the weekend.

You mention they can send you a loan chip, can they just not send you a flashed ecu off the shelf to keep?

Might be worth asking, i'm not sure why they dont do that really.
BBPT do it this way, you pay for the flash plus an extra deposit of £200 then they send you a flashed ECU to fit and the you send them your original back, upon which they refund the £200. The reflash is £350 from them though.

I believe it appears exactly the same as a the standard ecu in general. Obviously if a Renault specialist with the right equipment was able to examine the program then they might be able to tell.
Nik, can you post a few contact details for these people, I might be interested in doing this, never come across them before. Can you also provide a few practical tips on how you go about taking the chip out?Would it have any effect on a decat pipe?

Is this just a generic chip? But intended to match certain mods? Ie you buy a particular chip for a standard car, and a different one if you have an IK?

It's a remap of the standard ECU based on the Renaultsport Group N ECU that was available for the 172. The Group N programme was originaly developed by RenaultSport for enhancing a car fitted with the standard engine but sporting exhaust and air intake modifications. It suits standard or lightly modified vehicles. It keeps all the existing ecu features i.e. alarm, imobiliser, cruise control etc still work.
Fastchip and a few other companies have applied the same modifications to the 182 map. Fastchip do two versions, the standard Group N which i have and one which is slightly tweaked for use with a Viper induction kit.

I'll post up a guide to removing and refitting it later on, its fairly simple, just requires removing the battery as it sits over two bolts that hold the ecu holder in place.
Thanks for the links. I've had a look and they offer the group N update on a chip you can buy off the shelf as well as the reflash option. Has anyone got any experience of this, it would save the hassle of sending off my own chip? When I had my Impreza chipped the guys who did the mod put it on a rolling road, shouldn't the Clio go on a rolling road as well? Apologies for what might seem a beginners question!

With a turbo charged car, I believe the main change brought about from chipping is an increase in boost pressure, obviously this increase in air entering the engine has to be matched with an increase in fuel, so it is best to check the air fuel ratio on a RR for turbo charged cars.
As the chip in discussion here does not directly affect the amount of air entering the engine, the AFR should remain pretty constant, therefore the only need for a RR here would be to see how the chip has affected the power band.
IMO if you fit an induction kit to a 182 engine, you should also get the car chipped (for example with the second version of the chip from Fastchip discussed above), as the air flow entering the engine will have changed and I have heard of these engine's running lean in the top of the rev-range when an IK has been fitted. This is just what I believe, I am sure someone like Yozza (or any other reputable tuner) would be able to clarify this

I've just got off the phone to Henk at fastchip, currently he has not got any spare loan ECUs.
A new 182 ECU costs approx 400,00 Euros, so think I will wait till there are some available or try and borrow another car for a week.

what is the difference between a unichip and a superchip?
which is better?

I'm under the impression that the 'Viper' ECU software gives the engine more fuel at high revs to match the increased air intake from the viper.
As OilS has said above the engine can run lean using CAI's (cold air intakes).
