Hi Coops
I am running the chipped ecu and a bigger fuel pump and I have seen 163rwkw on the dyno at 15psi.

The chip changes the ignition and fuel maps to better accomodate the higher boost level and T28 turbo.

yeah i agree with tappet,

my ute just got Dyno'd n it's running 191kw at a safe tune,
i'm running a T3/T4 turbo and a mircotech ecu though...
boost starts at around 2500 - 3000rpm at 9psi up to 13psi at 7000rpm...

upgrade the injectors/fuelpump and afm, then u will see a big difference if remapped in realtime on a dyno...
if it's done right it will be better on fuel at cruise, better performance all round..

atm i would say u will have about 130-140kw atw around 12psi if the motor is healthy and u have a good exhaust /intake setup..
with a remap/inj/afpgrade u will be looking at 170-180kw safe tune..

Hey Matty,

Are you running a chipped standard ECU?

Kev's been talking to me about chipping up my ECU.
I'm thinking this must change the ignition / fuel mapping & I'm also told it increases the rev limit to 8200 rpm.

I'm just wondering what benefit's the aftermarket chip gives & if there's a noticable increase in power.

i.e; If I'm currently reaching peak power with the std ECU @ 6500 - 7000 rpm & there's no great increase in power with the new chip (just an increased rev limit) then I don't see much benefit.

Your thoughts?

Anyone else running the chipped ECU - What sort of power increase / change did you get?

Hi Coops
I have the bigger T28 off a GTi-R (.86 exhuast A/R) and I am making peak power at 7,000rpm. With the S15 200SX size T28 (.64 exhaust A/R) you should have peak power below this and it should be a nicer thing to drive as mine is a bit laggy.

I intend on changing to a the smaller exhaust housing when this turbo needs replacing.
Matty

all ca18 engines will run different, due to inlet lengths, exhaust size etc...
put it on the dyno and u will have concrete evidence when the torque drops off..

btw what size t28??? bb??

snap crackel pop then a bang

hahahaha... Good 1 .

But it should be just before it goes bang..... On the last corner of a perfect lap

when it goes bang :)

Thanks ca18det_man.

Hmmm, I wonder how running my T28 effects this?
Does anyone know where the T28 makes peak power.
ie/ Lower or higher in the rev range than the (stock) T28.
