Datalog problem


Heres a snapshot this is with 7 different logs files. Prolly 4 of which are passes down the track. Now I did check my TPS and its registering fine, I sit with the bike on and laptop hooked up and it goes all the way to 100 in ECU Editor, I even turned the bike on and bounced it off the rev limiter to watch the AFR and Throttle Position register in ECU Editor Data Screen and Datalog Screen. Now my bike is super lean, i know this, so is it because its at the full end of the spectrum maybe its not picking up the 5 volt signal?

Went to the track tonight, datalogging is only working at 9% throttle and down for majority. All the other cells are empty. Whats up? I was making passes during these logs so I know I had greater tehn atleast 9% throttle.  Also, it had a data point at 55% throttle and 800 rpm that's not right.

ok think i solved the 800 rpm with 55% throttle by looking at the CSV file or the logs. When the engine wasnt warmed up I would whack the throttle and it would bog down, that's prolly the reason for that. still no sure why i dont have any 100% throttle data

Everything in your map looks very lean. Perhaps you have the data filters set to filter out the data points that are occuring, i.e. the threshold is set at 15:1 or something.

Take a look at the filters and set them to really high values and see if there is more data.

Either way, I'd add some fuel.

correct, i agree but all the filters are turned off and the thresholds are all high. still didnt get anymore data.

Whats set in the autotune area

Assuming you mean autotune settings basically everything is untouched except I made the filter out numbers 5 and 24

Maybe the afr sensor is bad or needs calibration?

hmm could be but why then does it register down at low percent throttles, if it was bad wouldnt it not register right at all and not be dependent on throttle?

Just thought it could be one of those things you might need to cancel out, what if it is running in narrowband mode or something and jumping all over the place. Or maybe the voltage is not set right in editor?? If it isnt the TPS really there is only a handful of things it could be that are causing the info to get filtered.

If it is not reading in the .csv file, it has nothing to do with the filters.

Does the TPS read to 100% ever?

Gotcha so it still registers in the csv even if its filtered, either has to be the sensor setup or something with the another sensor/ other hardware fault.

 I have not confirmed, but I woudl assume it would since you can adjust teh filters after loading the file. Seems the data would have to be there.

Did you double check to use the correct wideband/narrowband settings in both the bin and data logging?

yes th TPS registers 100% on the datalog screen and the engine info screen. yes the wideband is set in every screen and in the .bin file. and good news for some crazy reason it started working. i basically went to the 100% throttle area and added about 25 units of fuel to the high rpm range, then made a pass and it datalogged the 100% throttle. maybe it was just so lean that it wasnt working right. I dunno. but i have datalog and i keep adding fuel and its still lean, so got to figure that problem out.

thanks for the advice. if you could hop over to the 1000 section i also have an injector balance problem.

I think your right i will be able to confirm with my old logs but the laptop is cactus at the moment. A quick way to confirm would be to check the csv and check the afr vs the tps you should have a clear idea to what is going on. I was trying to setup a chart form for ee so you can just check the Recorded engine data in a line graph format through the software, have got close but work commitments and my lack of experience make this difficult for me... -NT is any data at all getting recorded when it isnt working?

well it when it was super lean past the widebands range of 18 there was no datalog but when i added fuel to the top end and a lot of it, then the bike came off its super lean and into the range of the wideband and then it started datalogging. so i wonder if maybe the ecu editor doesn't like to record a solid 5 v signal?

 Should log it ok, maybe the filters were filtering it out so you could not see it?

If filters are off then it should be logging if there is a value received at the pin on the ecu...

 What wideband controller are you using?

Do you have any other means to data log the signal to be sure it is a good signal being output from the O2 controller?

My fluke meter will log min and max voltage. Maybe you could hook up a meter to it and see if the voltages are.

using wideband commander....yes its not the greatest but it seems to work, i like the multimeter idea though. i know it tracks though, the wideband and ecu editor agree when i put a butane lighter to the sensor.
