Both are RPM x Throttle based and the values seems like load but it's really hard to tell. Also, I believe that these are the maps that need adjustment to prevent the ASC light problems and other CELs.

Thanks, that's what I was looking for.

Agreed.



On a side note, I am curious about one thing regarding limp mode; on most turbo cars, there is a boost cut value, but on the X it seems like limp mode is a more advanced form of this. Is there still a traditional boost cut value/table, or are the airflow check tables and torque limiter tables a replacement for this? I'm guessing the latter, but I would like to know for sure. Thanks.

There is a standard 2D boost limit map which is based strictly on RPM and the values are in load.

Actually non of them are airflow tables haha
And I have a rough idea how it works now .. but I still have no idea how #4 affects the others since we never had problems with that ..

I can load the exact same maps from the JDM to a USDM and the USDM car will throw a CEL within 1nm on boost ..

Doesn't ECUTek call these table Trustfull Airflow Against Torque and Trustfull Airflow Check? The scales and values are identical to the ECUTek maps. According to G/Force, you don't need to adjust these maps on a 5MT.

Yeah, we never have these issues with the JDMs even with the SST models.

Give CBRD a chance to correct it first. No need to beg for someone.

Its a naming convention .. just like desired engine load is something I'm used to on the older Evos .. versus the ECUTek Engine Load thing ..

I chose airflow limiter .. and it seemed to have stuck

but the more I played with it and the more reports I get back .. it's actually not ..

Well for the benefit of the community, please share! What is the exact fix for the issue? From what I know, most tuners that have been able to avoid the issue simply look at what loads the car is hitting after the tune, then go into the airflow/torque limiter tables and airflow check tables and just raise the values by a certain percentage. Is what you guys are doing now too, or is there something else?

How would anyone know what Ecutek calls it unless someone is divulging Ecutek info.
So this is what it comes down to now, referencing Ecutek info to find a solution for an Ecuflash issue?

I was always under the impression that the object of the Open ecu stuff was to do something seperate and apart of the Ecutek SW etc.

Well we have tuned a ton of evo 10s with Ecutek SW and these problems do not exist. They spent alot of time and money to make a seamless product that can be delivered to customers without "bricking" ecus.

adjustment of those tables (which may or may not be a air/tq limiter)
has helped some but if you adjust too much it causes the same issue.
BDEL has to be adjusted as well and a few other little things

The biggest issues right knoware trying to figure out what these tables do and why. Most tuners just use an EBC or MBC and let the cel's happen. (car still runs pretty much the same)

Personally i think we will have this nailed down in a few weeks
