disappointing performance continued....UPDATED after a day at MRC Tuning

unlikely to be the pump imho
more like some other factor is causing the ECU to request more fuel
maybe the o2 sensor has died?

i was very fortunate to have someone down there from MRC Tuning who had a ED30 running at 395bhp.  he offered to give me one of his maps if it was running full power once he put it on.

Big turbo I presume?? 395hp is a pretty a 'optimistic' claim for a K04 car..

QD MBE:
What did he say about the MAF?  May be worth plugging another one in, just to test.  I think a sensor is fooling the ECU into thinking it needs to fuel.  Is the Air filter ok?  Bear in  mind where the car was imported from, that sand gets everywhere...........

If i knew which sensor.......................  

This bit does seems strange, and does discount the MAF.  But I am not convinced.

firstly he flashed the ECU back to standard which came up at 195bhp slightly under power but pretty close to what stock should be

May be worth taking a look at the MAF.

yep, i saw the car on the rollers and the print out - and that road is deemed to be pretty pessimistic in its results

I think theres been a mixup along the way with his documented engine code...because cars are LHD in the UAE, therefore meaning that his car can't have come from there  :smiley:
