Official OpenFlash Tablet FA20 Tuning Tech Discussion Thread

Hah my bad

[86-tundra]

I think @shiv@vishnu should organize a couple beginner tuning classes maybe once every week or so, in the evenings. I'd pay good money for that. And he could probably knock out tuning some of his remote tunes

Perfect. Connect oft to OF Manager with wifi. Erase data. Then reinstall as if it were new

Already got the new map flashed. Just wanted to make sure I had the correct steps before i proceeded to flash a new map. I didn't want to brick the OTF since the correct steps aren't easy to find. I'm sure it has been posted on the forum but searching for specific topics on this forum doesn't work all that well.

I did a log with OFT 1.42 stage 1 map
maf is recalibrated slightly by my self.

I think AFR under wot is bit rich . but its not post learned. so after few days. I'll do again.
besides that, very satisfied to map. smooth, torquier.

Pretty sure it isn't, the stock o2 sensor reads lower but is actually closer to 12.5 AFR

Hi! your WOT AFR looks better than mine on the same 1.42 stage 1 map.
What is your ECU CAL ID?
Here is my log with some wot pulls if you like to compare:
http://datazap.me/u/ondreiko/1-2-3-4...=1-3-9&mark=66
Let me know your MAF calibrating method, if possible.
In addition: And one more question - your log shows throttle position at 80 all the way - did you press the pad to the floor?
Everything looks like WOT pull, except your throttle position.

btw, your perrin inlet tube doesn't appear to be doing you any favours on the MAF.
It seems quite a lot more turbulent than @Ondreiko.

Hello Shiv

I am waiting for delivery of my OFH. Is it safe to run the E85 stage 2 tune with stock intake and exhaust?

I know nothing about tune. Im just trying to understand basics.
There is yike's spreadsheet for closed loop maf scale.
Jamesm' screencast is very helpful

Actually Im ecutek user, so I copied map values to make my file.
Maybe I forgot something related to throttle value. So 80% is wot for me

Your log is fine to my eyes =)
