Ok, as promised, here are the ports that I've been working on - AZ1G202I USDM STi 2008/9

Plug the following in for the definitions:

EDIT : change E_params to the 300's after discussion with Dale, to make it so we don't have interference with the new definitions.

EcuFlash def:

Awesome, thank you!

Where in the def file do I put the code? I'm really familiar with ecuflash defs but not with romraider. I tried putting it in the AZ1G202I and in 201, the base for that rom. Neither show the sd tables romraider. This is using RC9.

Those table definitions are for Ecuflash, not RR. Only the logger defs are for the RR logger.

In other words, the table defs go into AZ1G202I.xml

Even better. Thanks for the reply.

If you have tried used this rom yet, please inform if you have trouble with idle wanting to dip to 500 rpm randomly. I have yet to use this rom. But, another tuner contacted me about idle problem. Even after driving the car for a week.

If there is a problem it needs to be informed here. I'm waiting on the 06 sti rom to be posted to try on my wifes car.

Thanks for the work on the 32 bit stuff guys.

Ironically, I have not yet tried it

I think once the MAF blending table is incorporated, any low down drivability issues will be sorted. That being said, I've had endless issues with MAF scaling on my 08 EDM STI, so I can't wait to implement this.

So you implemented a new fueling scheme and did zero testing before you posted it?

I've experienced this, but there are so many variables with my car I couldn't determine the exact cause... 2.3l, changed cam timing, perrin leakual length header, no rear o2, etc.. It was better with MAF, but still crap idle.

Freon did mention that the top left corner is critical to the idle, along with proper injector latencies.

Of course it has been tested, I would not post it up without testing. Martin Donnon has tested it live, and it works. The code was also run through simsh, and the ram holes tested on live vehicles. Please reference Merp's thread.

Does anyone have this running well? I have tried 2 cars and neither will idle even if you pedal it. The car will start and die within 5 seconds. The only way I've been able to get one to idle is to double the VE table and scale the injectors to 500cc (on ID2000's on E85).

td-d · **Posted:** Tue Mar 20, 2012 6:58 pm

I've been running the AZ1G201G SD rom for a while now, working relatively well. What I did find is that you have to get the latency setting pretty close, otherwise you can land up with a loping idle.

I'm actually thinking of extending the VE table by one row so that a 300 RPM line can be used. My thinking is that setting the 300 RPM idle cells slightly higher will mitigate some of the effects of a loping idle - when the RPMs / MAP dip, more fuel gets thrown at it, so it doesn't cycle.

I've also defined the tau tables for my ROM, and disabled them - but that would only affect the high load cells.

Would you mind sending me your current map?

Afternoon gents,

Is it possible to create definitions solely for the SD rom, and one for the MAF rom ?

Unless I'm doing this wrong.

I added the code to the 201I XML. Now every 2008/2009 sti map I open up with ecuflash has speed density.

Come to think of it, I'm probably doing this wrong.

Pointers ?

No, it's not you - that's the way Ecuflash works. What Merp has done in the newer patches is given the SD roms their own CAL id to prevent this from happening.
