Dont forget you get $100 off on the OFT if you come from Ecutek

I believe James is referencing the 2.048ml injection limitation that the ECU seems to have. I know you could mis-calibrate (hack) the port / direct injectors to inject the wrong amount of fuel in which you would need to tweak a lot of tables to work properly as the calculated injection would be incorrect. This just may not be something everyone would be wanting to do lol. I don't know anyone with open source / oft that has pushed to the 2.048ml injection wall yet to see if it is ecutek related or just ecu related. Unless maybe you have?
On my own car I had to use a custom map in ecutek to inject past 2.048ml while on higher boost levels as the ecu would stop increasing the port/di open time at a certain point.

Maybe i missed something but i dont believe their has been a dyno comparison for base maps using ecutech vs OFT for this stg 1 package they are promoting. Lets wait for that before judgement. Then you two can start the next world war

His comment has nothing to do at all with a basemap and has to do with fuel injection limitations of this ecu that a number of us have been working with. But not everyone is trying to push that much on E85 some people are just wanting a tad more power in which it should work just fine.

Sigh... why would you need custom maps to overcome what is likely a hard set threshold, scalar or limitation of the data format (8bit or 16bit) - unless you really like doing things in a convoluted, round about way?
I'm betting that it's this value that simply needs to be bumped up: Code:
ROM:00059FD0 flt_59FD0: .float 131072.0 Or more neatly, as I've pointed out before, there seem to be two scalars that are used for the injector flow scaling in the BRZ, and it seems that it is the practice to change only the one - I'm betting that leaving the other at the standard value: Code:
ROM:0010DDDC Injector_Flow_Scaling:.float 12176.6 But yeah, I guess you could bypass the standard control logic of the ecu using custom maps tacked onto the main control routine, and achieve the same aim. Like you could reach your right arm over your head to scratch your left ear. |

You're going to need custom maps to run more than ~2 bar manifold pressure, unless they've done some sort of modification directly to the rom. If anyone has managed to run more than that on a stock rom without custom maps, I'd love to see it. Really it's a moot point because you wouldn't be running that much boost without flex fuel and speed density anyway. |

Well, that ticks off one item:
Limitation of the data format (8bit or 16bit) = the OBD routines convert the direct data, normally float, to either 8 bit or 16 bit (e.g. the DI pressure is fed out as 16 bit i.e. maximum of FFFF). That explains the 2.048 logging limit. This of course would be alleviated if you could just log the direct parameter. On the injection limit - I'm happy to work with anybody who would be running that kind of pulse width to find the limit / threshold. I'm sure we can modify the threshold or scalar 'directly to the rom' - not unlike modifying any other calibration 'directly' in the rom. |

Wanted to share some good news, Vishnu will begin working on Free OFT Tunes for the Automatic Transmissions FT86 next week.
We hope to release those to the public in August Chris |

Hope Shiv comes through with a tune once stg2 turbo comes out!
I really like how this kit looks in the engine bay and compatible with my OFT (: |
