Primary purpose is to log a wideband. But theoretically I guess you could log other sensors too that don't talk to the factory ECU. The DLP device has 8 channels.

Ah cool, thanks. I'm pretty happy with the fuel control based on eyeing the gauge, so no huge issue. Logging the knock sensor is great - if you see it pull a little bit of timing at a particular load/RPM, can just massage the fuel and timing a bit to resolve it then log i again.

Finally getting around to doing some wideband logging. Must be a dumb question - but once I have the drivers installed for the DLP-IO8, how do I get PCMTec to actually see it so it can log it? Cheers Andrew

Thanks Rolls! For some reason I didn't find that when I was searching, but it is what I need. Before I drove home from work this arvo I set auF0523 AD to 0 across the RPM range and auF0162 to 3600 seconds (one hour) at all coolant temps. To be sure, I'll set AD to -100 as per your comment at the above link and set auF2504 to 4096 degrees C. When troubleshooting a suspected hardware issue, it is neat to be able to use the tune to help isolate things!

Hey everyone. Related question - if I set the values in this table to zero, does this force open loop at idle?

Haha see you soon! I was in a good position because when I wired accessories into my BA it was one at a time and so was a bit of a dog's breakfast. When I replaced it with the FG, I could basically make up one loom for everything I knew I wanted so it is nice and clean. I then left the data logging wires for the wideband easily accessible so I could wire this up when the time came. Was barely a 5 min job ?

Things to do while you wait though...

Thanks Roland! Legend as always!

Mine arrived the other day - looks like a good bit of kit! Will knock sensor DMR logging be available in Professional?

Thanks - that's very helpful! I'll start wiring up for that.

I had planned to cut up a serial cable to wire into the aerial outputs on my AEM X series wideband (plus a serial to USB adaptor). I'm assuming what you guys have done with the above thingo is to use the 0-5v analogue output on whatever wideband you are using. I might go your route instead. That unit looks neat and I'd probably wire it permanently and leave it tucked up under the dash. Getting excited about data logging!

Thanks mate. It is a pity to lose access to those files as it was great functionality, but understand where you are coming from too.

That's what I don't understand - the file I pulled from my car last year still reads fine. Shouldn't two valid .tec files of similar vintage behave the same? Or do you mean that the files in the stock database zip file you mentioned now don't work on Enthusiast since the return to stock feature was added to Pro and Workshop?

Thanks Roland I am definitely using 0.75 but double checked against the detailed version number above to confirm. Tried everything you suggested (although I can't Create Stock File as I'm on Enthusiast - but can of course just open a file from the stock database). I then tried uninstalling PCMTEC, deleting the PCMTEC folder under Documents and then re-installing from scratch but have the same issue. I can recreate the issue even with files from the stock database that I have never opened before. Some files though do have fuel injector scalars visible. Is there anything else I can try? Cheers Andrew

Has anyone had an issue where they can't see some injector parameters (anything under the Scalars item)? For example if I open my own file I can see:: But if I open HAEDJG4 I can see: If I open my original file (which was a custom-tuned version of HAEDLL8 with factory XR6T injectors) and do a compare with HAEDJG4 (an FG F6 file) it doesn't show me that the those missing parameters are different despite the files having different injectors: However previously I grabbed the F6 injector data from HAEDJG4 and used it to build an updated file, so I must have been able to see that data at some point. (If I compare my original file with my current file that has HAEDJG4 injector data, the slopes etc are definitely different, so I haven't saved over my original file or anything). The above is just an example - lots of the stock files I open don't have the scalars visible. I'm using 0.75 and have selected Show All Parameters in the context menu. Is there an issue or am I missing something obvious? Cheers Andrew

OK so slight follow up here. I plugged the new sensor in to test it resolved the issue before jacking up the car and removing the old one. New sensor plugged in, still not heating. Turns out one of the pins on the Deutsch connector I was using at the firewall was loose. I soldered and heat shrunk everything and removed the connector and it is now fine. So rather than saying the sensor was very sensitive to being left powered on with the car not running, I would now say it actually survived a decent amount of mistreatment exceptionally well! And now I have a spare sensor for when it does eventually go bad

It was pretty silly. Basically spent a number of hours in January working on the car to service the ZF and fit an external transmission cooler and fan. Had accessories on to listen to music for parts of that time. The relay for my wideband is triggered off accessories on, so would have been heating itself for all of time. Even short periods of this can kill the heater circuit on the sensor. Just forgot and didn't think to not do that or pull the fuse. I think I will find an ignition on source to trigger the relay instead.

Hi again. In case it is useful for anyone else, I asked the question of Bosch, but the answer was pretty vague. I then asked AEM and was told: Both the Bosch 17025 and AEM 30-2004replacement sensor part numbers havebeen verified to work well with the X-Series wideband gauge. So buying the general LSU 4.9 is fine, and I suspect this is true for Innovate, etc too. I also worked out what probably killed my sensor, so hopefully the next one will have a much longer life.

This is kind of what I'm getting at: https://www.justraceparts.com.au/bosch-17025-replacement-oxygen-wideband-sensor I can live with changing the sensor every couple of years at that price.

Thanks Roland. Yeah I think the offset resistor is in the loom, but the sensor loom because it is specific to the individual sensor. What isn't clear is whether or not the wideband manufacturers have engineered in a difference, or are just implying that they have. While the AEM is self-calibrating it does also have a free air calibration feature , so I've got that option if I need it. I might get in touch with Bosch and see what they say - I'll share the outcome if I get one!

Hey everyone. Does anyone know if the Bosch LSU 4.9 sesnors are interchangeable between wideband controllers? AEM, Innovate, etc? The sensor in my AEM has died. It looks like all of the 4.9s have the same connector and buying a part specifically for the AEM is basically twice the cost of the Bosch part but I'm suspicious they are identical. AEM site talks about a resistor in the connector being calibrated to the sensor, but I'm guessing this is true if all 4.9 sensors, not specifically the AEM ones. https://www.aemelectronics.com/products/sensors-connectors-accessories/wideband-sensors-bungs-accessories/wideband-o2-sensors/bosch-lsu-4-9-replacement-o2-sensor

Thanks - that's useful! I think I'm basically at the point where I've got a decent but safe performance boost compared to stock, and now I can spend quite a bit of time learning and fiddling around the details more. Actually, the other thing I should mention from a safety perspective is that after a wrote the boost map, I compared both the boost maps and timing maps with a BA F6 to give me a rough indication of what I should work within that will give me a decent safety margin to avoid knock. As it is being road tuned I doubt I will ever try and tune it within an inch of its life. I'd rather keep a decent margin for changes in conditions.

Thanks - could be an interesting experiment! Which table drives idle speed when in gear? My car's combination of exhaust and probably slightly tired engine mounts causes a bit of annoying vibration at idle stopped in drive. This is especially so if lights, demister, etc. are loading up the alternator. If I feather the throttle it is much nicer, so I figure if I up the RPM slightly at idle, I should be good. (Although I should check out the engine mounts properly too.) I assumed table auF0022 (Idle RPM AC on in gear) and set that to 620 for IATs of 0-90. Was 580 I think. Doesn't seem to have made any difference. Maybe there is a scalar coming into play or maybe I should try adding like 400 RPM or something to the table so that there's no mistaking whether the change has worked or not.

After running the near stock tune for a few days, everything was behaving itself nicely, if a little slow Then built a tune with as much boost as I was happy to chuck at the stock injectors - about 9 pounds but tapered it off at higher RPM. Made some lambda changes too, especially at high load. Car feels good again and wideband is reading all good. Interestingly, my fuel economy has improved by about 10% compared to my original tune. I'm thinking that if the previous boost maps were targeting a set boost level across the whole map, or were open loop with the same wastegate behaviour across the whole map, then I probably had the waste gate either shut or at at least 50% DC based on what was in the tune. I'm guessing that would have been bad for economy due to the extra exhaust restriction at light cruise and idle? Anyway, is a nice bonus. I also flashed the transmission torque strategies back to stock for safety. I'd always thought the BTR in my old EL XR6 was a lot smoother than the BA, and the tune explains why. Happy with the stock tune in it because having the transmission last is ultimately more important to me than having thumping, ultra quick gear changes. So I feel like I'm pretty happy with where the tune is at for the minute, save for a couple of minor tweaks.. Time to get around to installing the trans cooler, bigger intercooler, 0.8mm spark plugs before I grab some injectors and go again.

Excellent, thanks for the help!
