RSport ECU in standard 172

[telford_mike]

anyone know whether this will work ok in a normal 172?

Apparently you can get one from Hillpower for the 172.. so yes.

same engine same car same ecu.

Ye but side airbags..

that was my worry - does the ECU only do the engine or is it the CC and all the other toys too?

Seperate module.

The PCM (powertrain control module) is shared.

The clio uses lots of other modules to control subsystems.

Got a group N ECU (is this an R-sport one?) in a mk2 172 (without EBD and TC) from HP - works no problems.

All is ok, works fine. Ring Hillpower.

hi mike

I have got one in mine works ok no problems, my car is the same year as yours with no added extras ( EBD and TC ). Ready to order one you will need the engine type code, this printed on the engine block behind the oil dipstick my code was 736 . Nick needs this code to get the right ecu. hope you have small hands and do not do it if you have been driving you have been warned.



Regards

Hi Rich hows it going mate Think Ill get Nick to fit it if I get one!

 

[Lee]

Im assuming it wont work on a car fitted with TC?

 

[telford_mike]

Now now Lee you know you said you wouldnt mod it... Bet it does work though

 

[JAY172]

the injection ecu doesnt directly control esp/tc but it is part of the system so im not sure if the group n ecu will work on the later 172s which have all the gadgets.

 

[telford_mike]

Almost forgot to ask - what do you think of it - those whove had it fitted?

I think you need to add anymore to that comment Mike.

Hopefully it wont work in mine with the TC, then I have a dam good reason for not impulse buying one.

Ill be sure and ask when I get mine fitted Lee

Mm, I can feel some scientific test on the strip coming on.

Well, I fitted mine at 2,000 mles and Im on 10,500 now...would I go back? Never!

Power improvements? I dont believe its done much, if anything, to peak power, but it does seem to have filled out and flattened the torque curve a bit.

For me though, the main reason for never wanting to give it up is the raised rev limiter. Maybe it was just me never having had a car as fast as a Cup before, but I was almost always bouncing off the limiter before I fitted it. I havent seen the gear-change light since (apart from testing to check it worked), let alone met the limiter.

As a track man Mike, Im sure you really know it makes sense...you can hang on to that gear for another 50 metres instead of having to ease off, or go for a pointless change prior to braking...

 

[JAY172]

im thinking about one of these,so you think its improved engine power lower down the rev range rather than peak power. you do think its worth it though?

Wow, hadnt realised it did that - whats the new limit? 8k?

 

[MarkCup]

Its gained 500 rpm and now cuts in at 7,750 rpm IIRC.

I should point out (just in case I ever want to sell it to someone from here) that I dont routinely (rarely actually) over-rev my Cup...I like to short-shift and know that if I want to I can really wind it up!

I think it was worth it in my setup but I dont know what it would be like on its own. The increased in gear top speeds are useful on occasion tho when you need to hang around in one with a few revs available.
