I was sad when I refreshed the DL page just now and no 1.5. Darn I wanted to play with it this weekend. Lol

Here are some Dynos results you are probably looking for

All 4th gear runs. Expect 4-5whp more in 5th gear.

Dear All,

Needed you all pro advice, i'm new with datazap and today have sometime to play with OFT datalog.

http://www.datazap.me/u/vynervt/18-j...log=0&data=1-6

Please share your ideas was i engine running in normal condition, Im using Stage 1 ZA1JA00J 1.42B version. Fuel is Malaysia 97 grade. (I don't what grade of OCT / RON). small modify on the intake duct and stock everything else.

What i see from the graph. My AFR gone from as rich 12.17 to as Lean 20.33 AFR. Is this normal?

As long as the AFR is 12 while at full throttle. 20 is normal if you are coasting in gear. I was more shocked at the date of your logs. You are from the future, it's only Jan 17th here lol.

AFR is fine. So are long term fuel trims. The 20.33:1 readings you get is during deceleration when the injectors shut off. That is normal. Once cruising under power, AFR will be around 14.5:1. And under WOT, you should see low 12s to high 11s.

Aside from AFR at WOT what else should i be looking for when reviewing logs?

@Rombinhood@OpenFlash or @shiv@vishnu: Is there any expiration on OFT Dollars? I would like to buy the tablet soon and use the OFT Dollars towards a header at some point, just not sure how long it'll be.

I've been playing with my oft a bit now, it has been great so far but one thing I would like to see is the ability to save multiple data logs instead of always overwriting your previous one. @shiv@vishnu maybe in a future update?

This is the biggest feature I would be looking for at the moment. Even if it could just append it so that the new logs gets tacked on to the end of what is already saved. Super simple to code.

Need logging capability for other parameters like IAT, fine knock, etc.

Here's mine on a post 1.42b stg 1 test rom. Computer is dialing back IAM at low load low RPM conditions.

Word. The Ecuflash guys have found some of this I believe so it should be very easy to add.

Yep... we are currently adding the option to log up to 32 channels (up from 12). So 20 more useful logging channels to come.
