hello, this time in a zetec turbo, decided not to compound someone else's thread any more.
basically i've gone from a chinese style t3/t4 to a gt3071r on a 0.63 housing.
it's in a forged zetec turbo setup with mild porting to the exhaust side, area six cams and springs.
since the change, when heading over a BAR i get surge, the only other thing i did was retard the inlet cam a little to combat an awful idle, i haven't touched the exhaust cam, although i do have adjustable pulleys to make life a little easier.

i have some pics of logs i've taken and all i've done in these is vary the gizzmo boost controller a little, these are my findings so far:

the first is on 90%gain 36%duty:


second run on 40% duty 80%gain


third is 45% duty 75% gain


(may have got settings slightly off, but you can see the changes.)

it's on MS so mapping is easily sorted, although the wideband is playing up a little, but is probably sensor on it's way out, just drops coms sometimes.
