OSE 12P V112

I've been looking at some of the tables a bit more.

Is it normal that using the stock supplied bins in the VE table from 7600 RPM and above to have values of 0 (zero) fill the table?

Also in the SA table, above 6800 RPM to have values of 20.04?

Comparing to a couple of the available custom cals was inconclusive, as to whether this was correct or or not.

the base bins only have upto the rpm of stock cals shifted over so above 7000rpm wont be tuned and just has whatever value in it same with spark the old code didnt go there LOL.theres only really 1 table to be carefull of that is zeroed out its Charge Temp - Boost % Coolant contribution for calculating charge temp Vs RPM & MAP

That what I figured it was, that the stock bins only when so high, and nothing had been changed in that regard when it was added to this code.

Thanks.

So I was able to drive my car around today on $12P. It drove well, needed some adjustments here and there, but overall pretty decent.

I have one issue while getting into boost it goes real lean. I've tried adding to the boost VE table, and it helped some, but not completely.

If $12P is like the North American code I'm used to, this would be due to ignoring values above 100 in the VE table, is this what happens with $12P?

I will definitely be spending some time getting this tuned on $12P.

Correct, you cant have more than 100 in the VE tables - if you enter it in TP will pull it back to 100 when you save it. 12P uses a boost multiplier table to compensate for this, you shouldnt need to adjust it from stock with a 2 bar setup.

If your hitting 100 VE then Displacement/inj flow rate (Litres/Grams per sec) needs to be adjusted.

Yeah, I know, I need to go through the proper calculation. I just adjusted it to where idle was good earlier, went from there. I knew it wasn't going to be right, but it at least let me drive around on it.

BTW, I have a 3 BAR set-up, and I do go above 200 KPA.

FWIW, I have NO idea why my car wouldn't start the other day. The only changes I made to the adapter harness was to make it easier to plug into my car, regardless of injector wiring pin out, since there are 2 or 3 different ways the injectors can be pinned, depending on how you look at it, for saturated and peak 'n' hold mode. I had everything matched up for pins the other day in my harness and adapter, but it just didn't want to fire. Today, it fired over without hesitation, and it was cold. Made a few quick adjustments and it was idling terrific.

The ONLY thing that was different was the ADX, which now shows all the values correctly, except the NBO2 sensor, it seems to stay pegged at over 900 MV, and I know it works fine when I'm running my '7749 and $59, or even $58. On the bench I can not get the NBO2 value to change from the default, regardless of the input voltage. I rely on my WBO2 right now for any tuning, and have $12P in open loop.

post up your base bin and ill have a look through it for you if you want or PM it to me if you want

Hmm, this is interesting.

According to the kinjflow calculator, I need a value of .05794. This is smaller than the value I used, which is currently set to .0872. The calculated value would cause me to need even more VE value to the tables. :/

For reference:
Petrol
2.8L I6 (so .467 for cyl displacement)
32 lbs/hr injectors.

Looks like I'm gonna need to just fudge this number, and tune from there. :/

If I double the displacement (effective displacement at 15 PSIG), I get a kingflow value of .115704

It seems this value could potentially provide enough head room in the VE table, but not sure if this would seem like a correct way to manipulate the numbers.

you need to add a bit on what it normally says, its more just a ballpark, at the end of the day i aim to have my highest point in the 100kpa column about 85-90 % so whatever injector rate gets you there!

mine works out at .026 on a 3.3ltr with 80lb injectors and methanol, but in the real world i have .044 in there! fuel pressure and real world factors all come into it aswell.

[delcowizzid]

how high is your ve at 90-100kpa in the 20-100 kpa table are you near 100%.i allways set the BPC to the worked out bpc from calculator or spreadsheet .i never lie to the ecu.
