Well ecunotemu seems you are right again you must have helped a few people thanks for what you do ??
They just trick the ecu etc into boosting fuel, even the mpg computer thinks you've improved mpg, but like I said, test before and after and you'll find no improvement, where as remap takes into all engine parameters air flow, fuel, temp, speed etc, and is tuned to your van and age and condition,
Try to google Quantum remaps and see if they are close to you, they did my 2009 2.3 and I think it has made a big difference to the performance and mpg
Regards John
I followed this thread with interest as I could not see how a generic module plugged into the OBD port could change the performance of an engine. The ODB port gives access to the databuses but it can't change data that is on the bus. I can only think that it is changing the fuel trims or similar configuration data. This is little different to the boxes that put a resistor in series with the temperature sensor. It is NOT a re-map. You can do the same with any decent OBD software tool. At best this sort of thing is a bodge, at worst a con. Oh, and un-plugging it probably won't undo any changes it's made.

Look at google and you will find that Quantum are in Belgium ?
Well m8, there was a definite improvement, however I had a niggling doubt so I have sent it back for a refund since I found this local guy:

He says chips just up the fuel injection pressure
Full remap 5 years guarantee etc €275
Can I get a quote for teeth whitening!?![]()
Since I removed the chip the engine has returned to its normal lumpy self, slow throttle response by comparison, so I don't think any permanenet change has been made
Just joined Robert. Thought CQ you. I bought recently a Motorhome with only 3,700 on the clock (a 2010). Its a Fiat Ducato Multijet 100. Runs well and I put a Solar panel on it after 2 new batteries were needed. Anyway I found the EM light was coming on. My m/c tells me its EGR...PO401..valve intermittent.
I have no info on where it is but I think its under the rear of the top engine panel. I undid the 2 screws but could not move it.
Any info (pdf or pics too) would be appreciated. Thanks all. Terry
Interesting, I wonder what it was doing. The only other possibility I can think of is that it issending a flood of "corrected" readings onto the bus which overwhelms the correct readings.
that of course assumes the engine ECU takes a relevent reading from another unit.
