How far apart are your timing maps? Are they in sync with each other? In Mitsubishi software you can actually see the logged parameter % of lower octane fuel/timing maps it is using.

I am un-aware that you can monitor that in the Uprev software at this point, but hopefully in the future.

my High Det and Low Det are quite apart from each other right now ,, for the simple reason that if the ECU is pulling timing , I will know it pretty much as soon as its happening.

there isn't a setting that I know about running a lower octane map with high temp is reached. maybe in the future.

If you tune on the street, you need to make sure before every single pull/ run or whatever, that your temps are ALL the same. It's a science; keep all the variables the same while testing, make one change at a time.

Anyway, just remember to have fun!

right now I do not have much choice on the outside temp. its winter here

but yeah don't worry about that , I do try to keep my temp equal every time I do a pull.
but since I know where the limit are from my tuning experience from last summer ,, I'm not trying to go farther because that will probably wont give any power

My next dyno tune is probably at the end of March or sometime in mid-April.

Back at it again over here. Since my last post, one of the later UpRev software updates has removed the Timeing_Det_Knock_Window maps out of the ignition tables. No big deal for me though as i wasnt about to touch them.

Then I notice another new section called SETTINGS, and a control for "ETC Control". Either its for Throttle or Torque control, or conjoinment of both. Its ON by default. Setting it to OFF does some good and bad. Positive; I notice better/linear throttle response from turning it off is which is a decent advantage. The negatives are that it disables cruise control AND throttle rev/matching for sport models. I'll leave this setting ON because I like those features of the car.

Looks like theres a new firmware update. SOOO many changes I wish these guys included changelogs with their updates.

hi,

I am searching to understand Timing Advance in uprev.
To avoid unnecessary reply, I know that if you will tune TA you need dyno and a knock monitor device. Than you may increase TA until power drop or knock listening...

Now:

1) what measures BTDC TA in Chiper logs?
Milliseconds or Degrees or something else??
If "something else", anyone known what is?

2) what measures Time for Max pressure in ROM Editor Maps?
Milliseconds or Degrees or something else??
If "something else", anyone known what is?

I know that Nissan assumes Max Pressure 12-15 Degrees After Top Dead Centre, so it is simple (I think) convert BTDC to Time to Reach Max Pressure....
...but now, I don't know the units of these parameters....

Thanks

Holy dig! I take it you have not seen any responses in the UPREV forum. I posted there and got nothing. You may want to contact on of the forum sponsor shops and bounce some ideas off of them. GTM, Forged, Z1, and Specialty Z are pretty regular posters on this site, so a PM should be answered with decent speed. You could always call them though!

I would give an answer. but I haven't played with the software at all.

EH! EH! EH!
...I wrote to uprev and in his forum also.... (my nick is always the same)

At now nothing....
So, I am writing in all forum in the world to found an answer!

Everything is started with this problem:
As manual describe, Ignition Timing express Time Before Top Down Centre (cvs column is "IGN TIMING (BTDC)").
First hypothesis is that are in milliseconds

So, to convert it on degrees I use this simply formula:

Degrees = TA / ms_for_360_degrees * 360
Degrees = TA / (1/RPM * 60 *1000) * 360

Now, in Excel appears only non suitable values like >180°.
Example:in a row of .cvs file I read TA = 28ms, RPM=1100 that result 184°!

It is important because I am studing a software to display statistics in .cvs logs.....
