Data Log Sample - Feedback

Got a chance to run it today. A little warmer out at 22 degrees. I added 6oz of Boostane and it seemed to make a difference, but still a little timing being pulled. You can see it didn't pull timing for as long though, so maybe this is quite a bit better with the added octane.

Got to use the Dragy on this run. I'll post those times as well.

If I were doing this I would try to be smoother on the throttle (on and off). No blipping. The big chunk of time under WOT where it is still pulling timing looks like its still not quite happy but I have no feel for what 'normal' looks like in a well tuned engine. One way to look at it is that for the 'run' of approximately 10-11 seconds approximately 30% of it happens with the timing being pulled. But again, I am a data guy, not a tuner so maybe someone could post a comparison graph.

I think what you see here is just noise. .5 deg timing is all, but it last for a few seconds so that is a bit weird with that much Boostane booster in there.
Wonder why its seems so rich at 10.7. It should be averaging around 11.7 during the course of the run at WFO.

What muffler and what are you using for air intake?

 

[snowdust]

I was wondering about it being rich as well. It’s upper 10’s the entire run. I run a sandale 2.5” stock modified muffler and a cai from prevost performance with the cone style k&n. I’d like to move to the 3” stock modified from td. Nice to have these logs now so if I do I’ll see how it changes things.

 

[KnappAttack]

I'd say the muffler might be a bit restrictive perhaps, and I'm not sure about that intake, I know Hurricanes intake filter has a nice smooth flowing airhorn inside which helps with airflow and leans the A/F mixtures too. Dave selected his air filter for that reason of added airflow.

 

[snowdust]

I’m guessing a muffler would lean it out but I may do the closed loop first. It’s cheaper and I’d like to see how it works on my sled. Muffler is probably next year.

How are you guys separating the different runs that have been data logged?
Do you shut the sled down after a run or do you log out of app?
Otherwise wouldn't it be be one very long log?

 

[snowdust]

I usually shut it down to reset but you can split logs after. I do that as well.

You can switch tunes on the go no problem, you can select tune select in the log to see what tune you are running on.

Yes its a long log, but you can zoom into any part of it. Its how I do it. I start logging all the time key on in the App. So if the sled runs it logging even if riding for hours. When I shut the sled down I quit the app, when I start it back up I restart the app.

Sounds like you and turboflash should trade mufflers ?? He needs lower AFR and you need higher AFR.

At the beginning of each season I find we hear about many guys getting knock lights. One thing I like to remind guys to alway take it easy for the first tank of the season unless you physically empty your tank and put fresh stuff in.


Here is a interesting graph I wanted to share.
While on my 240 header tune testing I got a p1236 code(sd26). When the code came up my afr spiked in the 14's and ran lean
Rpm were low @8500-8600 since weights are set for 300.
The pressure sensor froze is my guess
Map was still reading correctly


Pic are before and after getting the code

If you zoom below graph the numeric value of the white hatched vertical line in graph are displayed

Thanks
I intend to start logging as well...the data log feature has not been instinctive to me coming from PC5 Pod 300 Data logging on my SC Apexs

Give me a shout if you need help Bob. I am no 20 years old techy guy but got it figured out..lol
Go to your setting and put it on auto log.
I been connecting to my flasher and using a screen recording app for the live data along with datalogging
I like this also because you actually hear the motor in the recording

The throttle is actually wide open the entire time. It fluctuates between 99 and 100 for some reason

@yamamarc - Why is your IAT reading so low?
