Fuel/tuning Issue

[nisskid]

do you have the boost control kit?

when the PFC is data init'd to defaults the boost kit is turned on by default

this means, if yours was "reset" and you aren't using the boost kit the engine check light would remain on until you disable the boost control kit

the PFC has no limp mode or back out mode other than what the stock ECU has

and this is your typical if AFM is dead, cap rev limit at 2500rpm etc - really basic rev cuts and idle protection

it wont know if your fuel pump is being gay or leaking fuel etc

im not sure, it has a setting for boost control i think, but i have a HKS EVC as well, so not sure there.

My god son get it to a tuner it's obvious that the tune is on default maps - and by the sounds of it if there is no fuel leak than you must be hosing those bores with fuel. If it's got an issue withtge maps not storing than ashas been said check the keep alive batteryinput into the ecu - if it's good get a new PFC.

gave it a basic settings change last night, car is now running fine (albeit with less power and tonnes of lag)

for anyone interested, these were the settings i was given:

Seq.turbo cont ... default = on ..change to OFF

Inj/AirF Warn. ...default =on...change to OFF

Knock Warning ... Default on .....Leave ON

O2 F/B control (O2 sensors) ..Default =on...Change Both to OFF

Idle-IG Cntrl....(O2 Regulation) Default =on.......Change to OFF

then turn my injectors (beleived to be 700cc) down to 75% from the factory 100%.

for some reason the first setting (seq turbo) wasnt there, instead the boost kit option was there. i did everything by the notes, and left the boost kit on just to see, got a huge fuel cut, and sent the knock to 30. turned the boost kit off, and it seems to have disappeared.
