jamal posted:Hahaha what in the gently caress. "hey why am I getting a code for cam sensor plus misfires? oh well, probably bad injectors or the ecu" I know right  In his defense, it didn't actually trip a cam sensor code, and the 2nd injector plug was doing a very good job of hiding. I only worked it out when I went to plug the stock injectors into the harness to see if they'd click while cranking, and one of them wouldn't plug in...He's also putting sealant-filled heatshrink over all the bits of wire that he partially stripped for testing purposes, so I think we're cool. I'm still probably going to take it to the other shop (the place that has a lot more ECULabs experience) once I get it back, though. Just in case.

literally a fish posted:I know right what in the gently caress? He's vivisecting your harness to probe it instead of backprobing connectors or putting in test stuff properly? Please tell me he did this to the adaptor cables not the vehicle harness itself. I can see making that mistake, and I can see why the ECU was only occasionally throwing a code for the cam sensor... subaru really likes VR type coil pickup cam/crank sensors and a high impedance injector probably looks about like one (on an ECU dumb-simple continuity check anyways) until you try and get a signal from it. It would also maybe explain why it was getting real confused and sometimes not firing the cylinders on that head and cam sensor, too. Let me guess, cylinder 3 sometimes worked, and when it worked, the ECU was also throwing a code for the cam sensor? I don't understand blaming the ECU for this, but many mechanics do that, even people who should know better. Barring known histories and symptoms of failures (old Ford ECUs blowing their ignition driver, Subaru ECUs losing an evap solenoid driver when the wiring falls apart and shorts out, OBD1 Jeep SBEC ECUs starting to suffer from capacitor death... etc) I usually blame everything else before the ECU.

They did do SOME hardware testing - they tested the injectors before install, and they tested for continuity, found none, ran replacement lines from the ECU, and it didn't work because it wasn't triggering properly and they weren't testing the right wires It only took me about fifteen, twenty minutes - we both worked out the problem at exactly the same time. I was kind of surprised he hadn't tried plugging the stockies into the wiring in order to check if the ECU would still fire them or not, though. He was also midway through tearing down an Evo IX when I rocked up, I should have taken pics. kastein posted:what in the gently caress? He's vivisecting your harness to probe it instead of backprobing connectors or putting in test stuff properly? Please tell me he did this to the adaptor cables not the vehicle harness itself. Mmhm, exactly that. Yeah, cyl3 sometimes worked. I suspect it would have been throwing a code but I didn't ask. And yeah, I'm with you on blaming everything else before the ECU, which is why I couldn't work out what the hell was happening since the old injectors were 16 ohms and the injector dynamics ones are 16.7 ohms and it worked fine when I dropped it off - I'm glad I went up to check it out... I definitely won't be coming back to these guys in the future, but it was a relatively easy mistake to make and the cam angle sensor is pretty well hidden, if you're not checking it (which, really, you should be, if you have an injector or spark triggering issue) it's easy to overlook, so I'm willing to give them the benefit of the doubt based on this and having a chat to some of their past customers. I wonder what the impedance of the actual cam angle sensor is? Looked it up in the service manual - 10 ohms, so yeah, I can definitely see the ECU passing a continuity test and then going  when it gets no waveform.

It's an easy mistake to make, and it can be easily remedied by actually giving a poo poo about fixing the issue in 15 or 20 minutes of diagnostics instead of putting it off and not communicating with you for 3 months. I'd ask for a heavy discount.

From the way he was talking, I wouldn't be surprised if I hardly have to pay him anything at all. I supplied all the parts myself, too, so it's only been labor on their side. Slight correction, it's only been one month, but still. I'll deal with that once it's sitting there tuned and I have the key back in my hand.

I've personally witnessed a mid 90s Camry get towed to my old mechanic because it wouldn't turn over, even with a jump, along with a complaint of misfiring for a few weeks. ... turns out the ECU for some reason decided "one injector must stay open anytime the ignition is on", and one cylinder was full of fuel. Replacement ECU (plus an oil change) got it running again, but I'd guess it died from leaky caps. Can't really think of anything else except water intrusion that would make an ECU do that.

In that case it sounds like the driver for that injector (aka the big N-channel mosfet in the ECU) failed short (likely due to overheating / just old age thermal cycling) - which is another common failure mode that's easily diagnosed

Well now it's been a week since the last email I got from these guys again. Getting real tired of your poo poo, Cihan Aday. This will teach me to not go to the recommended guys, especially since now I will have to take it to them as well to make sure he hasn't done anything assfuck retarded. I'm gonna have to drive up again aren't I I thought these guys had just about redeemed themselves but I mean jesus loving christ how hard is it to send an email? I've got half a mind to show up with cops and demand my stolen property back.

Still having cam angle sensor issues. Shotgunning the problem with a new sensor and replacement wiring, then testing Saturday and with any luck to the tuner soon. New tuning place has been having some issues replying to emails (they're super busy) and asked that I call once I've sorted it so that's the plan there.

New cam angle sensor fixed cam angle sensor problem  New problem! ECU reports that MAP sensor voltage is too low. This should not be the case, as I programmed it with the curve of the new MAP. I suspect this is what caused all the issues the tuner had, as it will under no circumstances boost above wastegate pressure right now. On the plus side, I created a new tune file (since I wasn't sure what state the tuner had left it in) and modified it for the injectors / to make it a bit less lean in places where it was too lean, and it drives great (albeit at half boost and without sequencing onto the 2nd turbo) - it's almost like I know what I'm doing! Thanks, YouTube! Emailed Emmanuel to see if he can work out why the software isn't behaving. Hopefully a quick firmware update will remove the voltage check and all will be well. If that actually was the problem the whole time, I feel a tiny bit bad for the first tuning shop. Not very bad, though, as their communication still sucked donkey rear end.

If there is one universal law of modifying cars it is that 99% of "tuners" do more harm than good in the long run and if you find a good one then never go anywhere else. The second universal law is that it is always the sensors.

The second universal law is that it is always the sensors. Yup. I have, in fact, found a good one now - here's a sample of their recent work; (as always, click for full-rez)   That's a Porsche Spyder shell with a high-compression NA EJ25. and this is an STi  that has a power curve like this (red line is petrol, blue line is E85)  IIRC this STi was a stock setup running the CarBerry ECU ROM Their facebook page is full of pics of cars and dyno sheets and happy customers - and unlike the first guys I took this thing to, they actually respond to my emails and facebook messages, and update their page /very/ often. They're also recommended by Emmanuel (the guy who makes the ECULabs ECU modification) as people who actually know how to use the ECULabs software - and I can find a couple of ECULabs'd cars posted on their FB page. So on that front, I should be good. BigPaddy posted:The second universal law is that it is always the sensors. Well in this case the MAP sensor issue turned out not to be the MAP sensor's fault at all - Emmanuel found a MAP voltage upper/lower limit in the ROM which apparently is unique to the AU market version of this ECU, because OF COURSE MY CAR IS EVEN MORE OF A UNICORN. He's assembling a new firmware version for me right now

Hah yeah I have come across that before in an R34 GTT that was originally Auto and was converted to Manual but running the original Auto ecu. Needed to play with a few Nistune maps to find one that it would even start with before starting to remap it for the boost controller, exhaust, intercooler and bigger turbo. Unicorns are fun

^^^ If I'd had any idea how this would go I'd just have bought an FD RX-7 from the get-go, why get stabbed once if you can get stabbed repeatedly? Installed new calibration and a 3port BCS (along with map mods to ensure it doesn't overboost) and what do you know, now I get 1 bar of boost when I ought to! Except for some reason it doesn't transition to twin turbo mode at 3500rpm, it's doing it at 6500rpm. I have a sneaking suspicion that it's looking at injector duration as part of its engine load calculation, as the only thing I've changed against the base map was injector scaling and the cranking / tip-in adjustments to match the new injectors. Emmanuel is looking into it, as I don't seem to have direct access to any of the transition-determining maps (most of that is sekrit black magic that the ECU handles on its own) I have one further trick up my sleeve.

Hah, nah, I did some better datalogging and worked out it's just because it's running pig rich and the TCV/ECV duty cycle tables are all wrong. ECU waits until there's less than 2psi difference between the pre-spooled secondary and the primary before connecting the secondary's air output to the intercooler, and right now it's taking an extra 3000rpm to build that boost 'cause the fueling and duty cycles are all wrong. Duty cycle being wrong is weird, I need to investigate whether I'm actually using the stock maps (tuner may have hosed with the original map-file), but in any case it definitely seems to be fixable through software. In essence, it needs tuning E: I feel I should probably mention that this is just as much of a vacuum clusterfuck as the RX-7 setup, arguably moreso in fact. literally a fish fucked around with this message at 00:53 on Jun 23, 2016 |

I need to own less unicorns so I can do wrecker runs and get useful bits, like when my brother had a Magna and i had a '96 peugeot 306XT. Everything I own now is either too new or too weird to get parts for at wreckers. On the other hand, I have significantly more turbocharger now. I'd be down for a wrecker run in general but holy crap this weather lately has been HORSESHIT
