as above I don't think it's normal for the car to die I thought the revs would just become unstable and go up and sown not just die ???

Any body know?

hey mate, I had an issue with my air flow meters not too long ago. The car would idle rough and sometimes stall but when you accelerate it would simply just die. (leaning out, not a good thing).

The best way is to just flash the codes if it has a standard ecu and it should tell you.

What cars it for?

Rb20det wit stock ecu yeah I'll run diagnostic tonight I just will be swapping the car this weekend and want the new owner to know what's wrong before I do

I suspect either the air flow meter or coilpacks I just replaced the cas and retimed the engine and when it gets it seems to feel hesitant under light throttle and has a bad sputter which may be caused buy one of the two things?

Ran diagnostic and flashed 55 so nothing sensor related the ecu has picked up on

I'm leaning towards air leaking after the air flow meter ? Would that cause these symptoms I can not really think of anything that would cause this problem apart from that

Nah mate I wanna know if it should be stalling the car if I unplug it ?

From what i understand the ecu relies on the signal from the AFM to know how much fuel to chuck in the cylinders(for air/fuel ratios). So in answer to your question i would expect it to stall.

When I last cleaned out my intake with carby cleaner, pretty sure the following happened:

Disconnecting the AFM but leaving it plugged into the loom made the engine stall after a couple seconds, probably because ECU is aware of the AFM but getting weak to no signal.

Pulling out the loom too though, the ECU is getting no signal at all, therefore reverting to some sort of open loop mode and it should run roughly but not stall.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
