So I fitted the simulator/cheater today. I will post those results next week.

The results of the blanking plate with a check engine light:

The fuel econemy is back to old values: 15.41 km/l || 36.25MPG However this was incl 3 regenerations, so i'm certain it improved a little bit more than normal.

The strang thing though that was that it looked like my car switched between maps (if that is even possible). Perhaps because it doens't really know which sensor to trust, depending on the reading it switches map? I drive the same 200km highway everyday, since I live in the very flat netherlands I know this road very well. On specific points on the road it could do 14.5km/l || 34.11MPG while driving 120km/h 75Mph the next day, on the same part of the road with the same outside conditions (wind speed/wind direction) while driving the same speed, it could do 17.5km/l || 41.16mpg. Encouter this phenomena multiple times. Could be just an coincidence.

Anyway I fitted the simulator and did some ECU readings to see if it makes any affect on any of the sensor readings. Attached you will find 4 files (csv extension) This you can open with multiecuscan and check or uncheck some of the parameters to get a better view.

2 of the files are before I fitted the simulator/cheater. 1, in neutral gear with some various engine speeds. The other one is a short ride around the block. Same goes for the 2 files with the EGR simulater/cheater in place.

It seems that my turbo overboosts, do not really know if that's because of the EGR blanking plate, haven't noticed this overboost before.

Anyway, enough talk time for some attachments.

EGR simulator/cheater FiatMultiEcoScan graphs

Might be worth your while putting some fuel readings onto a graph, your air figures seem to be all over the place. How is it driving in general now, with blanking, and then with simulator ?

Below is a link with a graph with a bunch of parameters. Don't know if I got all the rights ones though.

Driving is just normal, no difference with the simulator. I deliberately drove around without the simulator for a week, to see if it made any drivability changes.

As I descriped earlier in this thread, the fuel economy changes from time to time on the same road & conditions. However I don't feel any differences, just seeing a lower economy than normal. I also have the feeling the turbo pressure is just a bit higher than it would normaly be. For example, driving 120/kmph - 74 mph (flat road) the turbo gauge pressure would be around +- 0.5 and my fuel econemy would be 17kml/ 40mpg. The other case on the same road same speed ect.... would result in +- 14kml 32mpg and the turbo gauge would read +-0.7

Any of the other members using the cheater/simulator experiencing the same thing?

See post #78 , it's just an effect of blanking the EGR

Wanted to thank you guys for this thread.
I'm also based in Australia (Brisbane).
I purchased a 2008 2.4 JTDm Ti a few weeks ago - very nice condition, 50100km.
But, after a couple of days, the glow plug issue and the hiccup around 2k revs issues reared their heads.

I fitted a full EGR blanking plate and this cured the hiccups and misses straight away. The car also kicked over quicker on start.
The torquey peak is now gone though and power delivery has been smoothed across the rev band. While I am very happy I have "fixed" the stutter, I miss the peak in the torque.
And sure enough, within a couple of days the CE lights came on.

A few days later, I cored my DPF and this improved things noticeably but I feel I'm still lacking that kick I got from the unmodified car.

So, today I ordered the EGR simulator from eBay (http://www.ebay.com.au/itm/06-AGR-S...534562?hash=item2a54374462:g:7cIAAOSwgQ9Vo3by).

I'm looking forward to trying it out once it arrives.
Do I need to have my error codes cleared though before I notice any benefit?
I don't have any ECU reset software, cables, etc and wouldn't know how to do it even if I did have it. My local Alfa mech wants $150 as soon as they plug their PC into the car.

Cheers

Error codes will clear after a few drives

Great news.
Thanks

So, I fitted the Tafmet simulator. Very easy to do and only took minutes including neatly routing and zip-tie-ing.

Fitting the EGR blanking plate previously resolved to hesitation issue I had but I got check engine notifications and noticed a slight loss in the strength of pull when the turbo built boost.
Fitting the simulator has restored the full push of the turbo and the check engine lights no longer showed the following morning.

A very worthwhile tweak for those who cannot get to someone who can remap their ECU or, for someone simply can't afford a re-map and better tune in the shorter term.

Finally I got a remap done, so the EGR is now deleted in the ECU. Thus I have a simulator which I don't use anymore.

PM if anyone is interested.
