    DATA LOGGER

    Hi Roland can I have the beta sent to me please. Thanks Scott
  3. Hey everyone. Related question - if I set the values in this table to zero, does this force open loop at idle?
  4. Added a HOWTO guide for reference
  5. On drag cars or on the dyno depending on your gearing and rpm limit, you may find a speed limit is occurring. There are two methods to disable the speed limit. Method 1 (maximum speed of 255 kph) For standard gearing and the 6 cylinder, this is usually sufficient. For the V8s spinning to 7-7.5k, you may need method 2. This method assumes the VID block is enabled (it is by default). auF0389 Activate/Deactivate VID Block Parameters for Final Drive/Tire etc = Enabled If the VID block is enabled the following scalar is used to determine the speed limit. Speed_limit_kph This scalar is limited to a maximum of 255 kph as the underlying datatype is a byte. If you need more than 255kph (can appear as low as 240kph on a roller dyno). Method 2 (unlimited speed limit). To use method 2 you must first disable the VID block by setting auF0389 to Disabled. Note that Mk2 Falcons use these overrides regardless of the setting above. IMPORTANT NOTE If you disable the VID block, this means the PCM will now use the values found in "VID Block Calibration Overrides" such as axle/diff ratio and various other scalars. Ensure the following parameters match their corresponding values in the VID block. Note that some of the scalars in the VID block may be set out of range, if they are set out of range you can simply leave them. Now you can use auF0397 Speed Limit No VID to set the limit. This is a floating point and can be safely set out of range to 1000 mph. Note. If you are trying to rev to a high rpm eg 7500-8000 rpm, the rpm limit hysterisis can be subtracted from the limit twice. This means with the default numbers your rev limit could become 500rpm lower than expected, this may appear to be a speed limit however it is a rev limit. To fix this problem adjust the hysteresis in scalar auF12252.
  6. Thanks for the reply, it's an interesting topic. Steve
  7. We are software engineers not tuners, we have tuned our own cars/helped tune others and we also have an intimate knowledge of how the PCM works but we are not mechanics or tuners so we try not to give hard and fast advice as there are more experienced people out there. We don't have a dyno or workshop and run everything from an office in SA with 2 remote workers (Darryl is in VIC).
  8. I was asking how you would tackle the issue, if it came into your workshop as I'm curious.
  9. If it is your car and you are happy risking the motor you can disable it. If it was a customers car you would be crazy as a fuel pump can fail, blockage in the fuel filter, injector blocked. Collapsed cat, all sorts of things that will make a motor knock badly. On a street car you aren't going to notice 2-3 degrees being pulled occasionally due to false knock so I would leave it enabled.
  10. So just curious, if you ran into this issue, you'd disable the knock sensor from pulling out timing, put your aftermarket detection gear, start ramping timing until safe. Would you then desensitize the knock sensor as now you know it isn't picking up any knock and be done? or leave it disabled?
  11. Knock sensors can pick up noise from piston slap and the valve train. They can also miss real knock. You can never be 100% unless you have aftermarket knock detection gear.
  12. It isn't magic. There is a spark adder (or subtractor) table which adds spark across the board. By default it is either 0 or subtracts 4 degrees. When it is turned on I believe the car was tuned with 95 octane, so when it detects enough knock it assumes 91 octane and pulls 4 degrees from the whole map. This logic is only turned on for the NA vehicles. You can set anything you want in this map though, and enable it on a turbo, not that I would recommend it but it is an option. These numbers are not necessarily true or accurate.
  13. Just having a brief read of this topic, do i understand correctly, it's saying that the turning on or off of the "switch" in octane allows the use of 98 or 95 with no further changes? Cheers

  15. I understand the importance of proper knock detection and is awesome using headphones (Adaptronic ECUs come standard with 3.5mm jack) but I've tuned plenty of powerFCs which solely use knock the sensor and can confirm they work a treat, same with the Link ECUs. Guess that's not the case with these here? figured they'd be better with the donut style knock sensor, if it's just a case of the knock sensor needs to be desensitized, that's an easy fix, it's usually what I do with the Link ECUs too, rule out background noise which I guess that's what I'm facing with this. Obviously headphones or aftermarket knock detection is the way to go, not denying that.
  16. I saw your post on facebook showing "1000CC" as the part number on those random black injectors. I would highly recommend pulling them out and putting something known in the car. One of them might be leaking as 9:1 AFR is maxing the guage out (they won't meter below this), to get that rich with those slopes something has to be seriously wrong. Those cheap injectors often are terribly balanced which means if you get your AFR correct you might be leaning out one cylinder and pop goes the motor. The saying "the poor man pays twice" couldn't be more true when it comes to performance car parts.
  17. Do you have anything that allows you to see fuel trims?
  18. The 16 limit is because the pcm only supports 16 high speed dmrs. We are almost finished adding single rate logging which will let you do 16 high speed and 50+ low speed dmrs (the more you add the slower the rate). BAA doesn't have high speed logging so you should already be able to log as many as you want.
  19. You guys really need to get some proper. Knock detection gear or at least Jimmy up some headphones and bolt a microphone to the intake manifold.
  20. Hey guys! I recently fitted some 1000cc injectors to my ba xr6t. I didn’t get any data with them. I used the data from the “how to” of scaling injectors. It runs! Not badly either. Afrs swing around abit but cruise isn’t terrible and wot is 9.0! Just wondering what I should do next to get it closer to perfect! Now keep in mind I’m a beginner, never done a injector swap before so I’m sorry if I don’t understand the first time haha. Here’s a pic of my injector data.
  21. Yep mines also a ba. I’ve turned kr limit down to 4 to stop it pulling too much and killing the fun. I haven’t hear any knock.
  22. Well guys I got it sorted out finally .. Cheers Barry in SA..
  23. Hey @Lucky So i worked out what was up with the wastegate DMRs. Looks like you can only log 14-16 channels at a time. Makes sense. You'll notice in the Scalars list of the ones you've added the ones at the bottom will be greyed out and will just not return anything. Now having said this i couldn't relate anything the wastegate logging told to what i had in the tune. Let me know if you have any luck With speed there are a few that makes but i haven't used: (under miscellaneous) VS VSBAR VSPD VSPD_CLSTR Other ones i have used: TCM_TFT - Trans Temp (F) INJ_DC_A - Injector Duty Cycle SPK_BDL - Borderline Spark Total for determining total spark SPK_M_B_T - MBT Spark Total used for determining total spark I'll keep posting up useful ones as, as you mention, is is pretty daunting when you open it up and are faced with soooo many options.
  24. Just waiting to get some time with the car, he's been a bit busy so haven't had a chance to fiddle yet, will update as soon as I get a chance, hoping for tomorrow. Is yours a BA as well?

    DATA LOGGER

    Thanks @finnigan001 just playing with the data logging now it is slightly overwhelming when you first open it up as there is so many options, I also tried the waste gate ones and didn't seem to record anything, do you know which one is for manifold pressure in PSI ? I think your above list is spot on with a few extras like car speed and boost pressure
  26. How’d ya go bud as I’m having the same issues.
