update on the car's boost problem...some issue resolved :-)
As the search continues......
today i got a new MAF...installed it and reset the ecu by disconnecting the batt....
1. boost dropping to 0.30bar max after 20-30 mins of driving (it'll turn back to normal once i turn off/on the car):
i drove the car for 45min tonite and the boost DID NOT drop...so i guess that issue is SOLVED (YES!!!)
2. BM not holding or peaking boost:
it is MUCH better now BUT if i am going through the gears....... say 1st to 5th gear (from 0-90mph)...in an agressive way......the boost will peak at 1.45bar (at 4k rpm) but drop quickly to 1.1-1.2bar (in about 1 sc)and hold till 5.5 rpm (with WOT)....and repeat the same at the next gear.....
but when i had just the N75 race alone....the boost would hold at above 1.40 level a little long and it the boost will drop in a slower manner...
and also it is also not peaking as high in boost (but only slightly)
but if i do a WOT at 70mph on 6th gear...it WILL peak at about 1.5bar and hold at about 1.35bar all the way till 120+mph
any suggestions????
