I'm still investigating the TB set up on the new astra, the injectors are red/brown in colour and bear the numbers (left side) S5WK90761 (right side) GM90501588. I haven't found anythign on these. Could someone help me with a flow rate of these please.
Cheers in advance
well going on the assumption that stock injectors are usually set up to run at 70-80% duty cycle maximum. the requirement on a 140bhp ecotec engine at 70-80% dwell would be about 160cc/min. so theyre gonna be in the 200cc/min ball park flat out.
That sounds abotu right, I had to up the fuelling recently as I'm sure you know about the idle issues with it Daz. it was sitting at 3.6-.7bar so bumped it to 4bar and it runs better but still has an eratic idle, next up is check their balance as I'm sure that's not helping. Still huntign software though
