Just done the rstuner thing and....

[daddycool]

well, i have some questions, but rather than ask i'll just list my observations and you tell me if it's standard practice while the ecu learns its stuff

1. it stuttered a few times at low revs (<2k rpm) even when warm.

2. after driving around for 10 minutes i tried a performance run and it hit the limiter at around 6500rpm. how long does it usually take for the ecu to release all its revs?

3. the throttle didn't feel as urgent, but it did pick up well. it felt the same as if you had a slack throttle cable. initial press felt a bit soft before anything happened.

4. once it got going it was a definite improvement. the kind of pull you got around 5k rpm now happens at around 4k rpm and it's a smoother increase.

5. with the limit i hit 101kw (135bhp) at 6100rpm, i won't read anything into this of course.

so, what do y'all think

2. - it can take a good 15-20 mins to warm up properly so yes that was still cold

 

[Tigger]

Did you have to unplug your cooling fan when installing the RS Tuner mate?

no thats only the clio 3 and megane 2

is the rstuner performance analyser thing the power at wheels or engine?

 

[Russ_16v]

must be at the wheels mate, even rolling roads only estimate flywheel (engine) power

 

[markkram]

Wheels and from what I've read on the Fastchip site an accurate weight for the car and a flat road are required if you want an accurate reading.

 

[daddycool]

yeah i went with 1200kg but perhaps i over estimated. i figured:
1021kg car
71kg me
50kg fluids guesstimate (half a tank of fuel, everything else topped up)
= 1142kg

i had some crap in the car but maybe not 58kg of crap.

 

[daddycool]

been driving it a bit more, like you tend to do.
it still hesitates a bit low down. again, just above 1000rpm and it kind of jumps. not very much at all, just enough to notice. it only did it once this morning but i'm learning to drive around it a little.
that slack throttle pedal feeling is still there but i think i just need to adjust to it. i would have expected a bit more urgency on a performance map though.
but i must add that it IS urgent once you get over that little feeling of slackness. it accelerates much quicker. i use to get a bit of a flat spot if i changed into 4th at around 2k rpm but that's gone now and the change into 4th is surprising, as soon as you go from 3rd to 4th even at low revs you don't expect it to kick as much as it does.

i use morrisons 95ron, i don't suppose that is part of the problem? the ecu should be able to adjust to this shouldn't it?

i'd defo recommend it, i just hope the little probs iron themselves out with a few more cycles.

 

[markkram]

Think all of Henks performance cals are designed to use 98 ron.
Have you E-Mailed Henk?

 

[daddycool]

alot of cars are designed to use 98 ron but the ecu adjusts to 95. (take a look inside the petrol cap on your clio)

edit: no not yet, i'll email him soon though. the manual does mention that it will take 10 cycles for the idle to settle so i'll give it a little longer.

 

[jjones82]

Henks performance maps are designed for 98Ron fuel, it still has the safety margins for 95 ron and that may well be the slight hesitation your feeling, you could always try some decent fuel and see what its like? But it will prob take a few tanks for the ecu to make use of the better fuel?

 

[markkram]

Indeed but you have overwritten the original calibration with a custom one that is designed specifically to use 98 Ron fuel. Why bother putting a performance cal on if you're not going to use the fuel recommended to get the best out of it.

supermarket fuel is probably the worst fuel ever known to man. i hate it,

i mapped my 172 cup with RS tuner and at the time I was using V-Power, now its running tesco Momentum 99 and its still running just as good if not better.

All comes from the same source mate

 

[sideways danny]

2. - it can take a good 15-20 mins to warm up properly so yes that was still cold

only if the stat isn't doing it's job.


and yes, before you say it, they all do it, because everyone neglects to change thermostats

 

[Russ_16v]

Oil temp i mean Danny - Im to used to talking about oil temp than water temp lol

 

[daddycool]

is the stat one of those "only use genuine renault" parts?
i was meant to fit a pattern part i got ages ago, but it didn't arrive in time and the need to get my car up and running was greater

 

[daddycool]

All comes from the same source mate

but then they add in their potions and frogs legs and bats wings to the base fuel

 

[jimjim150]

I've only tried a couple of tanks of Tesco 99 - but my car definitely idles/responds to throttle a lot better on Shell V-power; which it was mapped on.

I believe they both get their petrol from the same refinery in my area, though I know that fuel additives vary.

But for me the proof is in the driving.

 

[daddycool]

on drive home from work it's still hesitant. i put it in 2nd at 1500rpm and accelerated and it was the same
i've emailed henk, will see what he says.

First thing he will say is put some 98 Ron fuel in. :boring:

Momentum is a different league.

 

[daddycool]

i've got ported inlets and phase 1 air filter to go on. that will introduce even more air to the apparent lack of fuel at those revs. may have to live on 98.

i do about 200 miles a week, how long do you think it will be until i see the benefits of a richer fuel, or is it more to do with diluting the 95 ron enough?

This doesn't sound right at all

With the rs tuner remap the time before full revs is allowed is lowered - mine is around 2 minutes - definitely not 10
Mine idles a lot better with the remap on - no stuttering at all

Are you sure you've loaded the performance map on it and not just updated the software?

 

[daddycool]

there's a definite improvement in performance. i used the 6500_5404_98ron map
i mailed henk yesterday and he asked me about the front o2 sensor. that's quite new so just waiting for the next reply. i do have a fault code on the second sensor, but this doesn't do anything so not sure that's the problem.

 

[andywiddss1]

are u now running on 98ron fuel ,if not what was the point in loading a 98 performance map then running on 95 supermarket s**t

 

[daddycool]

it should still run on 95 ron without issue, just arguably not as potent

 

[Cookson]

flogging a dead horse.

It's written for 98, so run it on 98. This will stop your complaint, I AM SURE

 

[daddycool]

but a dead horse is all i've got :rasp:
i've still got half a tank of 95 so i'll need another week

 

[Cookson]

Take it for a good drive. You can empty half a tank in a couple of hours with the right amount of blasting

 

[The Fatty]

What is RS Tuner?

Worse fuel we have ever seen time and time again.

On a standard octavia back to back, i.e. drained it on the dyno then added vpower the morrisons fuel was down 10hp and knock correction of -7.5kw! Vpower had 0 correction

 

[daddycool]

is that a non-turbo octavia? if so, that's alot!

 

[Dunn]

Fuel makes a massive differnce

it will run s**t on 95ron with the performance map

get it filled up with vpower

 

[RSTuning]

is that a non-turbo octavia? if so, that's alot!

1.8 20vT 180hp

 

[daddycool]

8p/ litre difference! oh well, if morrisons is really that poor i don't really want to be using it. how is morrisons different to other supermarket 95 ron?

rstuning, i'm the chap that has been emailing you about the hesitant (kpmatthews@.......com) the lambda sensor is only a couple of months old, although i guess that doesn't matter if you think the fuel is the issue
