207 RC ECU reprogram

par **Sotiris Bouzikos** » 13 Février 2009, 10:42

you will not have to cut anything as you can easily add a plug adapter and make your job like factory do.
It is better to change the whole bov because of the better and stronger coil that vag have.
To be honest many people change the internal parts but the better job is to change the bov from vag as it can handle better and more intake pressure than peugeot bov...

hi
thanks for the useful infos
I have just ordered the VAG valve from an audi dealer.
tomarrow i'll try to replace the whole part.
i hope it fits easily and works fine.

and also i have found the ibiza's intercooler.
if anybody need here is the part no:

seat ibiza
year: 2008
engine code: 1.8 BBU BLZ
part no: 6LL 145 804

i ll work on to have it replaced with the stock one.

Is gas octane effective in ECU remaping?
do yu set it as a parameter while reprograming?
how much octane do you have in gas used in Greece?

It is because higher octane rating fuel produces less knocking.
That allows us to use more boost with more spark advance.
In Greece we have 95 and 100 octane fuel.

You don't really set a parameter while programming, but you tune more aggressively when you have better fuel.

No matter how aggressive the tuning might be, as long as the ecu detects knocking because of bad fuel, it will raise fuel consumption and reduce performance to avoid engine damage. It is just that if you use aggressive tuning with low octane fuels, you will get nowhere.

if i use 95 octane gas after stage 1 ECU, i ll lose power right?

Yes, you will have more power than a stock 207 but less power than if you had used 98 or 100 octane fuel.

Guys I have a very strange observation, each time I switch the A/C on I feel my car is pulling harder and also I think I am getting more boost on the gauge.

par **Sotiris Bouzikos** » 15 Février 2009, 17:52

Yes this is the way that ecu follows.
When you switch on your ac the map change for better acceleration...
At least that what peugeot says..

I thought maybe when the A/C is switched on, the extra fan on the stock IC is activated providing cooler air to the engine and hence more power.

If the map changes with the A/C then why don't you fool the ECU and make it think the A/C is switched on all the time ?

par **Sotiris Bouzikos** » 16 Février 2009, 11:11

no.Fan on the stock i/c is turn on when the temp rise up a little.
We don.t have to fool the ecu.The map is like that way that we don't have to do something more to make more power as a result.
The increasing power is not as much as you think.It is only for making the engine work propper like it don't have an ac if you know what i mean..

yes the A/C takes some power from the engine so they try to give it back.

Questions, questions..

After stage1 ECU upgrade, if I wanted to mount an ALTA downpipe, will I receive CEL?
can fuel remapping be adjusted already in stage 1 according to a beter exhaust way?
Is there a way not to use O2 simulators?

par **Sotiris Bouzikos** » 16 Février 2009, 16:53

Yes you can use this but better milltek.There is something in alta dp that is not compatible(i am not sure what).
You will not have any problem ofcourse and you don;t have to trouble with removing O2 sensors.
They will work fine as well as your stock dp..

Nobody but your tuner can answer you that question.
It depends on how strict the boost regulation is with his mapping.

Downpipes with free-flow cats tend to increase exhaust flow, thus making the turbo spool faster. So you will have more boost at part throttle than you did before and more high-end power.

can fuel remapping be adjusted already in stage 1 according to a beter exhaust way?

Yes. But because engine load is calculated using MAP sensors, when you upgrade the flow the engine goes leaner (until the wideband lambda compensates for that). Because at the same boost you have more airflow, which MAP sensors cannot detect.

Is there a way not to use O2 simulators?

Not that I know of. Until today I have seen no tuner claiming he can disable the O2 sensors and our technical knowledge on the MED17 ECUs is still very limited.

If I were you I wouldn't want to disable my O2 sensors. For a turbo as small as our K03s, there is no reason to remove the cat since the turbo's exhaust side is a lot smaller than any cat or dp.

does RC have MAF sensor as well?
maybe MAF detects the flow rise with high performans DP.

so i understand that an high flow exhaust system will need an additional mapping..

my concern is if i mount a different sport cat or decat instead of stock one, the O2 sensor will detect that is something wrong with the gas values and it will drop CEL. and after that, if i know correct the boost will drop to safe mod and performans will be lost..
is there a way to prevent it while remapping or we should use O2 spacers/simulators?

If you change your dp with another from milltek or alta the cat is sport already and have no problem to work with your sensor.
Just the remapping..

None of our PSA/BMW engines have a MAF. Our cars have 2 MAP sensors. One before the throttle valve and one on the intake manifold.
That is why the ECU cannot detect changes in flow.
So, your ECU it doesn't really care if you have your stock turbo or a GT28RS. If it goes lean then the wideband lambda sensor will try to compensate for that.

so i understand that an high flow exhaust system will need an additional mapping..

Usually. You could stick to a stage 1 ECU reprog if you don't get any antipollution faults because of too much boost.

Use a spacer. The ECU can only check the condition of the catalyst by the amount of gas fluctuation getting through.

To make it more clear:
The catalyst acts like a big filter for unburnt fuel.
The ECU always cycles from rich to lean around AFR 14,7:1 when you are at part throttle. Just a little bit, to refresh the cat and burn all the trapped HCs, and produce less exhaust gases.

So although the ECU cycles between rich and lean, the rear lambda sensor does not detect fluctuations in gas flow because the cat stabilizes it.

Once the rear lambda sensor records rich/lean fluctuations, it triggers a CEL for catalyst aging, it things the catalyst is not working properly.
If you use a spacer than the rear lambda sensor will not detect big fluctuations in exhaust gas.

The further away you put the rear lambda from exhaust gas flow, the less fluctuation it detects since there is no real flow where the sensor is located.

But be warned. This trick does not make your car road legal in any case.
If you use a bad quality cat, you will have exhaust fumes that do not meet the manufacturer's specifications.

I have 2 years more for car inspection.

but i guess rear lambda sensor needs heat to work.
if it dont gets warm then again I'll have problem..

i think im gonna choose alta dp for now.
i hope there will be no errors..
and i think car waranty wil end

Rear lambda sensors also have a heater, so you don't need to worry about them working. They work no matter what you do.

The problem with Check Engine Lights is that you get them if the sensor detects gas flow abnormalities or fluctuation.
You could try a Miltek downpipe. They seem to be working very well.

We do not know yet. The car has been driven for approximately 5000km already without problems and I read that many tuners are offering similar torque with ECU upgrades.

Since the connecting rods are common between 175 and 150hp engines, they ought to be reliable.

Only time will tell if the engine can withstand the abuse, but so far things look good.
