Confirmed, moving to ignition switched solved the issue. And now, reading the manual, it actually does specify "ignition switched" not accessory. My mistake. Lol. Thanks again Adam!

Roger that. I'll make the changes in the wiring and report back. Thanks again Adam!

Hey guys, I'm having a bit of an issue with my Link CAN Gauge, sometimes after engine start, it won't receive data from the ECU (WRXLink9) and just shows zeros until I restart the car. It's connected to accessory switched, does it need to be on the ignition "ON" position so it retains power during cranking? I'm assuming it must be dropping connection or something. any help is appreciated, thanks guys

Hello again gents, So, I went back today and added the data that @Adamw very graciously provided me, thank you kindly! I also made a new idle ignition table, which still needs a bit of tinkering with, but overall, it's idling a million times smoother. I also had a fiddle with the fuel table as I noticed it was idling MUCH (.6 Lambda) richer after adjusting the dead time and minimum PW, and it also seems to rev smoother now too. Idle seems to sit about .920Lambda at idle now. Map/log attached for perusal. Thanks fellas. idlelog2.0.llg idle2.0.pclr

Hey Adam, just got home. Bosch part number is 0 280 158 040. So they're just the generic 980s. Cheers.

Greatly appreciated mate, thank you!

I'll have to get a pic of one when I'm near the car. If this helps at all - these are the ones I bought. http://www.sonicperformance.com.au/BSS950/***SPECIAL***-Bosch-Fuel-Injector-980cc-3_or_4-Length/pd.php

I'll also add that it has Bosch 985cc injectors, a Walbro 460 pump and Radium regulator, if anyone has accurate data for the injectors that I've not been able to find by Googling.

Ah roger, my thought process was back to front. Lol. Appreciate the insight there mate. Roger that, time for a visit to the tuner. That's a big list. The car has been on the street I'll go ahead and make changes to the boost solenoid wiring, minimum effective PW, and FP sensor calibration. Unlikely to improve everything much until the VE table and multi-fuel tables are setup right, then we'll go back to idle tuning.

Hey mate, I just had another look at this map, and I'm not sure mines backwards. If you retard the timing as the idle is falling, you're moving away from MBT and the engine is making less torque, which won't speed it up. Conversely, if the idle is above target and it ignition is advancing, the engine speed should increase.

Roger that. Will do.

G'day guys, Took my car out for a drive today and after it was all warmed up, it tended to stumble and stall when returning to idle, which is fairly standard. I'm trying to understand why it's doing that before taking it to my tuner, does anything stand out as obvious? Log and tune are attached, cheers. idletune.pclr idle.llg

Thanks Adam, I ended up rewiring it and making it work. Good to know, appreciate the insight.

Did you ever get an answer to this mate? Currently working on my EZ30 swapped Liberty with this ECU and my fuel pump relay is wired to C-16, but it's apparently Aux 7 which doesn't turn it off

Neato, thanks for clarifying. I'll leave it as is for now.

Oh, okay, I didn't realise that, thank you. Is there any issue with leaving the ISC pinned to Aux 3 or should I move it? For reference, this is a factory 02-04 Outback/Lancaster H6 harness used with a WRX9 plug-in.

I'm going to have to take another look. Clearly something's gone amiss. I thought about my process. I switched to Test mode (ON) and the ISC clicked after I drove it high. Then, I went back to PWM test mode and it was responding to frequency. Very possible that driving it high loosened it somehow.

So, general update. Everything seems to be working. Only little hiccup at this time is that the idle speed controller is, for some reason, wired to Aux 3 which according to the Link contents, should be wired to Aux 5, 6, 7 or 8. So, may need to repin that baddie as it also needs to be driven high, which is a bit confusing for my tuner. Tests confirm that with the ISC driven low, it will not work.

Thanks mate, got that all sorted. I've attached the pinout from the PCLink software so you can see where the confusion came from.

Hey Adam, I got the injectors all firing nicely, all sensors working etc. What I'm struggling with on this ECU, is cylinder 5 ignition and tacho output. With the WRX7-9 w/ Ethrottle model, the expansion harness starts with Ign cyl 6, not 5. Supposedly it's used as the tacho output, however that's not listed on the pinouts in the manual. So I have no idea which pin is used for the tacho, the FSM's for the model this ECU supports indicate it would be pin 22 on plug C, which is currently my cylinder 3 ignition. Can you/anyone shed some light on this? Also, I have the tacho wire for my gauge cluster however, it doesn't respond to any output. That may warrant some further investigation.

Hey again Adam, Thank you for your help so far, you are a legend! I haven't checked the base timing yet but I have confirmed the injectors and coils are wired correctly. I did assume they were given that it is a stock Outback harness, lol. I also completed a better trigger scope for your perusal. Cheers mate!

I promise I read that. Haha. Whoops.

Hey man, As far as I understand re: MAP sensor, you can replace your existing MAP sensor with a new one using the same wiring (obviously, make sure the Vin, gnd and Vout are wired correctly, lol).

That's good news! Haven't been nearby the car for a minute so haven't managed to have a tinker. I'll redo the trigger scope when I can and check the base timing. I found that the map has ignition outputs 5 and 6 set to "tacho" and "off" respectively, whereas injection outputs 5 and 6 are set to "engine fan 1" and "IC spray" respectively, also. Will these be corrected on the ECU when it gets turned over? Again, I'll have another look when I'm nearby Cheers mate, Tim P.S. some questions may seem a bit low IQ, I do apologize

Howdy howdy, we're back again. Made a couple log files, it didn't fire and the trigger scope looked... weird. I logged the standard running parameters and the trigger scope. NOTE: engine temp was high as I had driven the car recently with the stock ECU. IAT sensor appears to be faulty. ez30logfile.llg Trigger Scope Log 2021-01-3 8;36;04 pm.llg After checking the trigger scopes, it didn't seem to capture anything. Hmm. I'll have to try again.
