have been an avid lurker for a while now and have just started my '92 1.6 turbo setup, ExtraEFi PNP, T3 turbo, with external wastegate, 425CC RX8 injector setup.
Running a MAP sensor and boost temperature sensor setup and an old techedge wideband.
Have it idling after a minor hicup: injectors 1 and 3 hosed enough fuel for it to drip out the exhaust joints (grounded wiring) It did however start on first crank and promptly gassed the street.
So after greeenpeace came round to advise me of the error of my ways: Injoector Prob Sorted, and the car idles. I am running tuner studio and have a base timing map and VE table to start from. Reinstalled 420cc injectors, and they pin out fine re resistance post hosing incident.
Base engine timing set at 10deg at appix 900RPM
Static injections at 360dec
2 x squirts per cycle.
Car runs at a high idle - during start up. Ignition advance after multipliers ~35Deg. Physica idle screw all the way in, idle can be brought undercontrol with less advance.
The Initial Problem (after teh exhaust/sump of fuel one)
All warmed up, and ANY throttle opening off of the high idle results in a very high AFR, plus popping In the turbo or manifold, and a drop in torque (basically farts an dies
Messed a little with ve maps - slight improvement actually moved off idle.
So: Frigged the required fuel to give a higher duration (about 8ms) and I can move off of the high idle with a poor transient response to the throttle opening/blip
Idle is also v rich.
I am running v v v lean off idle using the calculated fuel settings from TunerStudio (calc'd 425cc, 14.7 afr target, 1600cc = 3.2ms duration)
Soooo. I have read that the required fuel calibrateable is basically a scaling factor for the VE map, I believe that adding duration effectively richened it up, fine with that but:
- What are others running with the RX8 yellow injectors?
- If I am the odd one out, why would that be?
- How are others dealing with transients (in my case I'm stuck at the blipping the throttle stage) have seen that there is an accel enrichment option
I actually don't know what fuel pressure I have - though believe the car was a stock '92 which I have bolted a turbo, EFI and a downpipe that took precisely 1 million times on/off the car to get to fit (though I got good with a grinder and TIG by the end)
Yes the car is real, and yes I no nowt as concerns Gasoline Cal, but I am getting there, any suggestions welcome.
