  1. I've had this exact issue with the trims intermittently adding fuel at startup and also the needing to rev or drive it after it started, to fix the issue. Turns out I had melted narrow band wiring from a 4 inch dump install. I did replace the NB sensor with another second hand unit as part of the diagnosing process so that may have had something to do with it.
  2. I saw this happen intermittently but restarting the program seemed to fix it.
  3. My suggestion is to use knock ears and adjust from there. You can switch them off but you need to work out for yourself if it's the right thing to do. Needless to say, don't just switch them off because someone said it'll be fine. It might be fine and it might not be.
  4. Open PCMTec and type in "knock sensitivity" into the search bar and it'll come up. The enthusiast version has the sensitivity tables and the professional version has the knock window variables as well. In my experience you don't want to reduce the numbers in the tables by more than 20% otherwise the knock sensors won't work. You can work out what the safe numbers are yourself if you are inclined, by using knock ears, logging and spending the time to dial the tables in entirely. In this regard it's similar to dialing in cam timing. You need to have free dyno time and know how to do it yourself, or have money to burn.
  5. Almost every wideband is going to output a 0 to 5 volt signal. Usually it is on a spare wire that isn't connected to the wb gauge. You connect this wire to the DLP8, which in turn is connected to your computer via USB. You can configure PCMTec to output a data channel based on whatever signal the DLP8 is seeing. So it goes; wideband=>DLP=>USB/PCMTec The first post in the thread shows you how to set it up. Have a read of this for what the DLP8 can do and how it works: https://www.dlpdesign.com/usb/dlp-io8-ds-v17.pdf
  6. Ok thanks for the info gents. There seems to be some conflicting views on this which don't help matters. As long as we have the correct info, it doesn't matter where it comes from.
  7. I feel like I'm missing something here. I have flashed both pcm and tcm just a couple of days ago with the reset adaptive flag checked (it's always checked and has been flashed dozens of times), and the car is driving fine with no perceivable difference in the shifts and operation, unless of course a transmission function has been updated. I haven't changed ZF03182 however and I don't think I will, unless I want to find out first hand if there is a difference between that and the reset adaptive function. There is this... Then there is this...
  8. I'll post some more info tomorrow as it's hectic around here in the evenings with dinner making and kids etc and I can't really escape to the car lol.
  9. If clicking the adaptive reset clears the box learning after flashing, it would have issues until it re-learned the clutch wear wouldn't it?
  10. Roland explained it differently in the thread that I linked. I'm not gonna bother quoting a bunch of stuff. Have a look and tell me what your thoughts are.
  11. I've added a shitload of trans logging stuff and everything was zeroes or not working except for gear shift flag, tcc duty cycle and one or two other things. I spose I'll have to play with it a bit more and see if I can get something happening. I've tried the trans connect/disconnect and it makes no difference.
  12. The software doesn't indicate that, although on first impressions it looks like it does. There was a post where this was clarified but i cbf finding it. Here's the post.
  13. That's great that it has come good for you 😁
  14. Haha think about it this way, why pay for an e85 tune if you can just run 98 octane and it'll be fine?! But in all seriousness... you probably can but it's not advisable. The e85 tune will have about 30% more fuel so it will be too rich. The e85 tune will have (should have) too much timing in it also, so any attempt at brisk acceleration or boost, could and probably would make it knock. If you tried to floor it then it would likely misfire and eventually foul the plugs. Misfiring and knock under load are a very bad combination to have. The O2 sensor will take over when various conditions are met and you could probably drive around gently like that if you had to. Basically 20% throttle and nothing else. There is a fairly strong possibility that it wouldn't be able to start or run until the O2 sensor takes over (roughly 40 seconds from startup), in which case the plugs will be fouled and will need drying out, cleaning or replacing. So the proper answer is no, but there are things you can do, when you know how and why things do what they do. Google "fuel stoich" and you should find some useful reading material.
  15. It's an auto non turbo pcm with a 3.23 diff ratio. It doesn't say what it is but it is August 6th 2007 so it must be a BF?
  16. I dunno, maybe. I'll take a look in a minute.
  17. There is a calibration list in the PCMTec program. You'll be able to see what it is there.
  18. I'd suggest doing the gentle driving and let us know how the trans is behaving afterwards. I recently tried some different trans tuning and was getting a slight flare between shifts when driving super gently. I just went back to my previous tune and it was fine again. I might try the changes again and give it some time to adapt.
  19. A quick question; if you can read and save the file when it's locked then what is to prevent someone from taking photos of the relevant parts of a tune and manually entering them into a new tune? It's slightly tedious but worth it in some instances. If (?) you could compare a locked file to stock then it would be very easy to find the modified scalars and tables etc.
  20. Straight e85 for now. I'll get a flex sensor etc one day. I'm interested to see how you go with this as it's likely you aren't the only one seeing this.
  21. I've since rescaled the injectors (bosch 1000's) with id1050x data to suit e85 (available on the injector dynamics website) and I've removed the delay table completely. The cranking is the same and the cold base is the same and it starts every morning these past few days. The high slope is 67 and the low slope is 58. It isn't perfect (I just haven't put in the time yet) but as you mentioned this info will point people in the right direction and should definitely gets peoples cars starting on e85.
