Hill Power - ECU and Silicone hose kit!

telford_mike · May 11, 2004

Spent a very pleasant morning at Hillpower drinking coffee and chatting to Nick and his Dad. Had the Rsport ECU fitted, along with the silicone inlet hose kit.

Startling improvement in the car - much more responsive in every gear, and the rev limiter has been increased. Car is also louder - harder edge to the sound like a touring car now.

Engine idles at 1300rpm now - this is a characteristic of the ECU apparently.

Very happy bunny

NIIIIIIIIIIIIIIIIIIIIIIIIICE !

I am off to sell my kidney so I can get this done along with an exhaust !

This will be done soon ! Definitely !

he certainly knows what hes doin Nick......

JJ172 · May 11, 2004

Did you also have the HP IK fitted? How much did the ECU mod cost?

telford_mike · May 11, 2004

Didnt want the IK. ECU is £270.84 fitted, after Cliosport discount.

Engine idles at 1300rpm? LMFAO Ill like to see that pass an MOT

Paul C · May 11, 2004

and i am sure your rotbox will pass!!

BenR · May 11, 2004

why should it idle at 1300 rpm?

telford_mike · May 11, 2004

Dunno, but it does - they all do with this ECU apparently

Tom · May 11, 2004

errm dont sound right that.

Daipac · May 11, 2004

Can someone who has the R-sport ECU post and let us know what your engine idles at ?

y0z2a · May 11, 2004

erm, i dont think mine does with the rsport chip (i dont know if this is the same as the HP one)

jon_r · May 11, 2004

sounds like it is stuck on a cold start programme?

Any reason why you didnt want the IK? Id have thought it would have matched the ECU perfectly?

mines an Rsport ECU.

Tighten My Nuts · May 11, 2004

Ive got the R-Sport ECU fitted and...

Cold - idles at 1,000-1,050

Warm - idles around 800-900

Never seen 1,300 at idle

BenR · May 11, 2004

Yup....cant see why it should ever idle at 1300rpm even if its a characteristic of the ECU.

JAY172 · May 11, 2004

everybody withs cups above have normal idle speed with the ecu but mikes is a normal 172. i wonder if the extra equipment that interacts with the ecu on a normal 172 causes this high tickover for some reason. anybody else on here got the r-sport ecu on a normal 172 not a cup?

Daipac · May 11, 2004

Good question Jay, I am not sure if ayone else has it for the 172, not read anybody who has it done.

Maybe a call to Hill Power 2moro will help answer that question Mike ?

JAY172 · May 11, 2004

well the ecu on the cup although it has a connection with the airbag and immobiliser it doesnt interact with systems such as traction contol,esp or abs like on the 172. this is the only real difference between the two models that could explain it.

Daipac · May 11, 2004

Mike has an 02 172 which does not have TC, could it be the ABS that is causing it to idle higher than it should ? Surely it should have been mentioned when fitting ?

JAY172 · May 11, 2004

it could be the aircon or abs connection thats causes this high idle then.

ian172 · May 11, 2004

what is the break horse power increase with this ecu??????????????

JAY172 · May 11, 2004

not sure. think it improves mid range torque though.

The BHP gains are slim to none but the gains come in the torque department and the rev limiter is increased.

JAY172 · May 11, 2004

bumped this back to the top because im interested to hear what other 172 (not cups) owners say about their group n/r-sport ecu operation.

anyone got a normal 172 with the group n then?

telford_mike · May 11, 2004

me too Jay - been out in it again tonight, had a good look, idle seems to be about 1100. But oh the performance increase....... mwuhahahahah

How can you gain torque without BHP?

JAY172 · May 11, 2004

defo thinks its the extra systems on the normal 172 causing this idle problem. you think the ecu is worth it then? considering one myself.

telford_mike · May 11, 2004

Ive never been so happy with a single bolt-on mod to be honest Jay, the difference is massive.

So what do youthink about this idl business? Can this be adjusted or is it fixed by the ECU? I did pick up a price list from Nick while I was there and theres a group N cam conversion too - I was wondering whether the ECU expects a wild cam that wont idle at normal revs.

BenR · May 12, 2004

I dont get it.

All this GrpN stuff.

If you read the regs for GrpN cars then engines especially are std....cams a no no so i dont see how they could be anything but std cams if they are grpN.

The GrpN ECU for that reason isnt expecting a wild cam.

BIGDAVE · May 12, 2004

I have an R-sport/Hillpower ECU on my MK1 172 and mine ticks over at about 750-800 rpm,i have never seen mine tick over at 1300 rpm,id call hillpower and ask them about this.

Max172cup · May 12, 2004

I think mailto:M@thew">M@thew had a R-Sport ecu on his mrk2 172. Hes taken it off and got a superchip now i think, but maybe ask him about it.

telford_mike · May 12, 2004

Strange thing is that Nick told me about the idle speed when I first rang him up about it - not like it was a surprise to him or anything. TBH it doesnt bother me at all, but its a mystery thats for sure.

Nick has a group N cam conversion on his price list (I saw the actual cams in a box today!) Theyre Renault cams (or you can have Kent for a few quid less), but whether theyre actually group N or not I couldnt say.

BenR · May 12, 2004

Nah, its more my weird annoyance with the use of GrpN term being flung about all over the place.

jon_r · May 12, 2004

^ i would agree. I think giving it some Motorsport associated name helps them sales wise.

telford_mike · May 12, 2004

In that case I wish they wouldnt use that description. "Go faster ECU / Cams etc" would have done the job for me!
