OpenFlash Tablet v1.55b: BIN files added!

[Shiv@Openflash]

UPDATE:
ROM support for A00I has been added to the OTS download folder (v1.59). Available for download here: http://openflashtablet.com/products/...ads/index.html

No tuning changes have been made to previously supported ROMs so no need to reload maps if you were already running earlier v1.5x maps.

Any chace you could answer my AFR questions

700I is already supported (has been for a few weeks). The only currently unsupported ROM in the I series ROM family is 900I. I can add support for that as soon as someone sends me their original 900I ROM.

As for you question about AFR, i don't believe there is a need to rescale MAF so that the values in the primary fuel table reflect logged AFR values. Nothing is wrong with doing so but it's unnecessary. And doing so incorrectly will likely cause actual problems. On gasoline, AFR at WOT should be in the high low 12s, taper down to high 11s. If they are richer than that (and you are running the stock intake), it's probably due to fuel formation. The OTS maps have been calibrated off of the ethanol "enhanced" fuel we get in the US. So it has 5-10% ethanol content. If your fuel has no ethanol at all, you may find yourself running slightly rich with the OTS maps. Long term fuel correction should work it's way negative over time which should bring AFR back to the desired range. If not, you can always enlean the values in the primary AFR table (under load) a bit to get the desired AFR values in the logs. But realistically, you'd have to be running quite a bit richer than desired to really see a loss in power.

Thanks shiv,
some more happy aussies i believe !

I am running low to mid 11 afr at WOT with 98 RON no ethanol and still 11.6-11.8 on fuel with 10% ethonol (100RON). Stock intake and exhaust

I have filled up every day for the past 3 days (keeping the tank full in case th corn juice disappears again) and I have been paying $3.60 right on the Orange Ulster line. 93 is $4 everywhere.

Is this with the Stage 1 map?

Yes stage 1 map.

On the original stock facrory A01G tune oft logs showed low 12 (12.1-12.2) afr at wot on 98RON ethanol free fuel

I compared the stock maf scale to oft stage 1 maf scale and its about 10% higher above 2.7v than the stock map MAF scale through to 5v.

I wonder if our maf was scaled different in OZ for fuel ??

I believe stock MAF scaling values are the same regardless of domestic market. So it is probably something else that is causing your car to run slightly rich. It could even be wear on the o2 sensor itself for all we know. Easiest thing to do would be to enlean the values on the primary fuel map as described earlier. But I wouldn't get too aggressive without confirming that the changes actually yield power gains which requires a dyno. These engines are remarkably tolerant of running rich. In fact, I've seen more instances of power loss from not running rich enough in the 5000-6500rpm range!

Hope is not worn out its less than 6 months old, few other aussie guys run pretty rich as well.

That's the link! You guys need to rename the link on the page for xxxxx1.59.zip too


Thanks!
