Forgot to attach.... Here's the .pclr we ended last night with. Other than CLL Auto-mode, everything is working well.
-
Okay, so we we're able to resolve the issue last night. We re-calibrated the trigger with a timing light and adjusting the distributor until we had default timing to 10*. After this, we also added a shield ground to the NE and G2 signals. Anyways, now the car runs completely normally. We also updated the firmware.
One question...After updating the firmware, I can no longer chose "Auto" mode in the CLL options. I only have stoich (narrow band) and stoich (wide band) available. Is auto mode disabled in the new firmware for some reason?
FYI...for future reference, for a 3rd gen 3SGTE the G2 signal IS correct. We found this in one his shop manuals...

Trigger looks ok, so I wouldnt bother looking much closer at that yet.
Even though your post says "lots of smoke and rich raw fuel smell from the exhaust", you have a very short pulsewidth at idle so it could be that the injectors are working in a non-linear region causing the swinging AFR. As per JMP's suggestion - bumping up the Master fuel would soon confirm that.
Two other things that stood out to me:
- The Log shows MAP at idle of 30KPa, that seems unrealistic for a poor running engine. I would expect it to be more like 45-65, so I suggest you check the calibration of the MAP sensor against a known good gauge.
- You are on old firmware, I suggest you upgrade to the latest.
- When I open your .pclr, it says "ecu disabled", I didnt think it would run like that so I suspect this flag is in error but can you confirm that this ECU has been unlocked?
I unlocked the module but I must not have saved the .pclr afterwords.
I performed MAP sensor "calibration" but did not crosscheck the MAP value with his boost gauge - I'll do that!
Okay, so I'll give the master fuel a try, although it didn't seem to be a true lean condition. I believe its registering lean on the Lambda sensor due to and ignition misfire, not under-fueling. While we had it running I slewed the base fuel high in the idle region and it didn't seem to resolve it.
I'll try some more stuff and post a new log when I can! Thanks guys...

Hi All,
Just yesterday I installed a G4+ Storm into a friends MR2 with a "gen 3" 3SGTE. Install went smoothly, all wiring seemed okay, and the engine starts and runs but its really rough and is clearly misfiring at idle (roughness, lean spikes in AFR, lots of smoke and rich raw fuel smell from the exhaust). I've checked the trigger values which are OK, I have no trigger errors, and the trigger signals themselves look okay...(see attached photo). We had Trigger 1 wired to "NE" and Trigger 2 wired to "G2" on the distributor. There's a lot of conflicting info about which Cam pulse to use, so we tried wiring Trigger 2 to G1 and it seemingly made no difference. We double checked that G- is wired to a sensor ground, however there is no shield (this is the way it was wired from the factory, evidently).
Any suggestions what next to check? I've attached a short log and the calibration file also.
Thanks!

Simon,
The new unit arrived this morning. Two things:
- Shockingly fast shipping/service. Thank you sooo much for promptly addressing my issue and providing the replacement unit without a hassle.
- The new unit is installed and working perfectly.
Also Kudo's to your Distributor Innovative Tuning. Mike and Ian we're great to work with as well.
Thanks again!
-
That looks as expect. I think we need to get the unit back to test and fix.
Simon,
How can we arrange this as soon as possible? I've got a rally on the 16th of October I'm preparing for.
Do I deal directly with you, or should I contact my dealer?
If you can, reach me directly with email - [email protected]
Thanks,

Here's a screen shot of my runtime values from last night.
Battery voltage has been ~13.4-13.7
-
I just went to go look at the runtime voltages. Didn't see a list of internal voltages...
I did however notice that without the engine even running (Key on, engine off, ECU initialized) that Baro crept from 99-102 in the span of ~2 minutes...
Definitely seems like something is wrong.
-
Simon,
If I check the internal voltages, what should I expect to see for BAP?
I tried to upload a log however it wouldn't allow a .llg file.
Thanks,

Check what the MAP is reading at key on engine not running. If it matches the baro then it is likely atmospheric changes (however rather large one)
If Baro is out compared to MAP then we do have an issue that will need investigation.
Today when I started the car MAP=100 and Baro=96. As the car idled and warmed up I played around with some ISC settings and tip in enrichment. Within a span of ~10-20 min Baro crept up to ~104.5kpa. This, in my opinion, is absolutely NOT a real change in atmosphere. Here in Michigan, Baro is usually ~99kpa. 1-2kpa change is more reasonable....6-10kpa? no way.
I spoke with my distributor today (Innovative Tuning in New York) and ordered the expansion connector so I can configure my IAT sensor. After this, if the issue is still present we'll have to proceed with further investigation.
Should I log this and send it along?
Thanks!

Hello all,
I just got my VPS2 plug in board installed yesterday in my V2 ('96) WRX. I performed all pre-start checks and started the engine with no issues. Drove around for a bit tinkering with base fueling and then brought the car back home. Sitting in the garage playing around at Idle, I noticed that BAP had crept up to ~108 kpa. when I did the MAP sensor calibration before starting everything seemed normal (BAP=101, MAP=100.5). I currently DO NOT have an IAT sensor configured (on my to-do list) and the car isn't fitted with one from the factory (no IAT integrated into MAF sensor). I have not changed the Barometric sensor configuration either, its still set to "Standard".
What could cause BAP to slowly increase as the engine is running? If its an internal Baro sensor, shouldn't it be constant?
Any help is appreciated.
Regards.

Noted, thanks. Could have sworn I saw it as an option while setting the Lambda input.
Thanks for the help!
