Now Available: OpenFlash Tablet Datalogging/Datagraphing (BETA Release)

One thing I've noticed with the international ROM guys is that LTFT is quite positive, causing them to run rich at WOT. This does suggest fuel composition differences (compared to US fuel). Maybe it may be an option to disable LTFT learning. I don't see that being a bad option since they don't have access to E85 and don't need to be able to adapt to different ethanol content (AFAIK).

Hi Shiv!

I just made another pull run and it shows the same 11.25 AFR pretty straight line on WOT.

Later refueling i will try to log on another manufacturers fuel.

How can i disable LTFT to get it leaner? Or will you be able to probably arrange it among G-series roms mappings?

set the highest learning load bucket (currently 40g/s) to something higher than 60.

Also, when I tried to download the second log last night, the manager said the tablet had to be initiated and I had to calibrate again. This happened twice within minutes. However, the tablet still had the original ROM stored. Not sure if this has anything to do with the advance multiplier or not.

Ending up erasing everything and starting from scratch. Still no IAM or KC learned (unless I'm having huge knock issues). I guess the old 700C is a bit different.


From what I understand, flashing the ECU will overwrite the entire software load. So when I flash, these parameters (IAM and KC) will function properly? Will I have any problems since this is an old ROM?

If you have a 700c why can't you flash to stock, take it to Toyota or Subaru and get them to flash to 701c. It's a tsb and shouldn't be an issue?

Unfortunately I don't believe Subaru ever released a TSB for this?

No idea but you are not the only one. It doesn't work on the ZA1JA01I either.

I believe Subaru's solution was to actually replace the ecu. It's been over a year though.

Can anyone answer these questions?

This is strange. I'm not getting any other reports of 700C ROMs not logging IAM and KC. I have even seen datalogs from 700C customers showing both channels logging properly. The only time IAM and KC won't log properly is with the stock (original) ROM. But once you upload one of our OTS maps, you will effectively have a A01C ROM and both channels should log properly. Unless something else is going on, I have not had any other reports of 700C not logging IAM or KC. But I'm open to the feedback of others just in case there is something else going on that I'm not aware of.

I am still on the stock ROM. If this is the way it is supposed to work (incorrect IAM and KC on the STOCK ROM), then there may not be a problem at all!

Correct. Looks like there is no problem after all. Just load one of our OTS maps
