Remap finally done , a bit more punch in all the gears , he said fuel pump was doing fine as it was , time to see if the mpg improves now too , the boost is now up to 1.45 bar form around 1.3
Who did the remap and what power did it make? smile

A chap called Paul he is from Uxbridge pm if you need his details , it was all done on the road , we lowered the boost it was originally hitting 1.5 but he felt it was probably a bit high and would be better at 1.45 , it was ok at 1.5 but was close to boost cut level , he estimated around 320 to 330 as it was thought Jap cars are around 285 , he said if I was going more then a new pump would need doing , he said pump was ok at 1.5 , and I'm not fussed about changing the pump , I just wanted a bit more sensible power , I feel a drag race v fsti coming on

Really pleased you've got a good result. Circa 330 on a newage makes it a lovely road car, very tractable and easy manners, I'm sure you'll throughly enjoy it.

Thanks for the offer although I take my car to EngineTuner.

I'm glad you've got the right result and are happy! smile

I don't blame the mapper as when he did it the car was fine , but since the map the amount of boost it produces went up and now it's hitting the boost cut , he's coming out to turn the boost down , it appears the Ecu continued to learn after the map and allowed it to boost higher any thoughts any one , what s boost cut set to ? Do some raise it or is it as high as it should be ? There is clearly a lot more grunt in the engine due to boost levels

Its colder now, so you get a bit more peak boost in the midrange, simply a case of trimming the duty back or putting the boost cut up further

Is the cars preset boost cut quite low and need raising or is it just needing a map boost tweak ?

IIRC the max you can set them too is 1.6 bar , the standard map sensor won't read about that

Well map been tweaked now target boost is 1.45 which its does easily and I think peak was just over 1.5 I think he said 1.54 , it was going wrong in the lower revs around 3200 rpm , so he did some thing around those revs I think he said 97 per cent duty cycyle but I don't confess to understanding it but car appears better , not lost any power , and now hopefully will be ok on a cold day
