I have an R Sport ECU!

Frosty · Mar 21, 2003

Had the R Sport ECU fitted today. I was expecting little improvements here and there, but the results are much better than expected.

The car is really strong when pulling away (even just driving in traffic) and you dont have to rev the car loads just to get it moving now like you did before.

The torque comes rushing in just that little bit sooner, and feels quicker in every situation. Best of all, it now revs to 8,000 rpm and doesnt feel one bit asthmatic until about 7,800 rpm. Its not been on the rollers as I dont see the point because re-maps are all about driveability, and the ECU is worth every bit of the money it costed.

The ECU is a Renault part and is fully approved in all warranty aspects.

oooooooooooooohhhhhhhhhhh rev limit sounds good he he he

Viv172 · Mar 21, 2003

sounds good, what did they charge??? and did you get it done at a Ren dealership??

RobFenn · Mar 21, 2003

You should get it RR for our benefit!

Frosty · Mar 21, 2003

I got it done at R-Sport this morning. Costed about £280.00 after VAT and labour.

I dont think the rolling road will do it justice and show just how good it really is. The throttle response is just something else!

SHORTY · Mar 21, 2003

come on how much was it

aaronc · Mar 21, 2003

would love to go for a blast in a cup, never been in one. especialy a chipped one.

BenR · Mar 21, 2003

the wonders of changing ignition curves..........lol

Agreed...

paddymph · Mar 21, 2003

Will be interesting if an engine goes bang at 8K RPM!!!!

please post total price, phone no and website....I think they are going to be busy!!!!!!

Do they quote any figures on performance gain???

Simon172 · Mar 21, 2003

sounds just like my group n ecu. Revved to around 8000 rpm and drank fuel.

BenR · Mar 21, 2003

yea, mine goes to 8k, is completely happy and no worries for the entire time ive run the chip.....but the crank and fly isnt the best balanced item, and you go get a few vibes extra....

Frosty · Mar 21, 2003

The exact cost all in all was £280.35.

You can contact them on 0208 540 9991. There is no website that I know of.

The performance they quote is around 5% increase in torque. I havent noticed any difference in fuel consumption yet, but have not driven it much since having it done.

Im sure the major changes were on ignition curves (as BenR said) and not on injection curves.

As I said before, 5% seems a great deal more when you actually drive the car.

Also the top speed of the car will be significantly higher unless they have limited the 5th gear revs electronically.

Note: The ECU is only for Cups, not standard 172s, although there is one in the pipeline so I am told. Dont know about warranty for this though.

teady172 · Mar 21, 2003

Someone with a MK2 172 has already fitted one!

ak_uk · Mar 21, 2003

Funny you say that BenR cos thats sort of what Nick at HP was saying.....about the balancing....

paddymph · Mar 21, 2003

hmm, why shouldnt the Cup chip fit a non cup 172 then???

teady172 · Mar 21, 2003

Eagle said yesterday that he had fitted one to his MK2!

steve-hall · Mar 21, 2003

The cup chip will not fit a 172 because a cup has a throttle cable instead of a fly by wire system

BenR · Mar 21, 2003

the cup is cable!!??

BenR · Mar 21, 2003

photo please

steve-hall · Mar 21, 2003

as far as I have read yes Ill dig my camera out 2morrow if its true

paddymph · Mar 21, 2003

hmm, im sure theyd keep the fly by wire wouldnt they?

Nick Read · Mar 21, 2003

Maybe they had trouble with them rebooting the system in the middle of a hairy corner?

KDF · Mar 21, 2003

as far as I was aware the Cup was also fbw throttle

BenR · Mar 21, 2003

wouldnt understand why they would make a 3rd throttle body?

paul172cup · Mar 21, 2003

My Cup has FBW throttle same as the 172.

BenR · Mar 21, 2003

there u go, question answered.....

wonder how people who own the car cant tell the diff!??

Mrdemon · Mar 21, 2003

the ecu does not work in a mk2 2 172 still.

They have tried it and it f*cks up the engine.

WHy i do not know.

Also the rsport ecu does not take into account a sports exhaust or induction. which is poor.

S600HBY · Mar 22, 2003

The cup defo has fbw throttle, not sure i like it and the clutch is a pain in the arse. It seems to have two biting points just when you think your going you let the clutch out a bit more and it bites even harder. With the throttle you dont seem to have as much control when holding on the clutch, it either revs its tits off or stalls. Maybe down to me driving totally different cars, cup not too bad after a few miles

Really?

what did he say about it?

Seems like something they skimped on, with the flywheel weights being crap.

PM me

tumbleweed · Mar 22, 2003

The Renault ECU upgrade is not exclusive to the Cup owners since both cup and 172 have same engine. My friend has fitted the new Renault ECU to his Mk2 172 without any problems.

I am waiting until all tune upgrades are out for the CUP before fitting them to my mk2 172

abbs_172 · Mar 22, 2003

The cup defo has a fbw throttle as Reno told me so on the phone...a few interesting points about the cluth I can still stall mine if i dont rev it slightly on take off....

Frosty who did you get to fit the ECU was it a reno garage or the boys down at r-sport?

Think Ill be ordering one nxt week after pay day!!!

visceral · Mar 22, 2003

Ill have one too!!!

where r renosport based??

Simon172 · Mar 23, 2003

Save yourself the fitting fee and do it yourself, its quite easy. Unless theyve got to plug it in or something?

But if you do decide to DIY heres a tip: slide the battery back a bit before you do anything.....took me ages to undo those bloody nuts on the ecu case with the battery in the way!

Frosty · Mar 23, 2003

The ECU MUST be fitted by a Renault dealer or R-Sport themselves (like they did for me) for warranty approval!

They told me it didnt fit the standard 172. They are the ones who developed it, so I would have thought they would know more than anyone.

JJ172 · Mar 23, 2003

Frosty - since the 172 and Cup engines are identical, it makes a nonsense out of the statement that the R-Sport ECU wont fit a Mk2 172!! Sounds like a marketing ploy by R-Sport to make 172 owners wait, then charge them more for the same part!

BTW, anyone know just how much is stored in the ECU i.e. alarm settings, codes etc? Are there any issues in swapping ECUs if this is the case?

The sooner someone gets one of their chipped cars on the RR, the better, so we can all see the power gains!

Frosty · Mar 23, 2003

Well the ECU does a lot more than just the engine management. It also manages airbags (172 has four, cup has 2), climate control (cup doesnt have it), rain sensitive wipers (cup doesnt have them). The list goes on. All these features are ECU-controlled and not implemented in the Cup ECU.

Im gonna get my car on the rollers soon so we can visualise whats going on.

kaos__ · Mar 23, 2003

who can give me the part# *please*

How would they know they fitted it?

What i would like to know is if you make other mods wont it f**k it up?

I have an R Sport ECU!
