I appreciate the replies.
ABS fuse was thrown in the bushes the day I got the car. No ABS, no TC. I should really setup a camera, as I can't live log the OEM ecu sadly. Maybe there is a way to log the ECU so I can look after, but I know live isn't possible with the OEM ECU. |

I’ve seen others say similar about the long hold. I’ve never noticed much of a difference on blips. I’ve already said it in this thread but switching to E85 was the the only thing that solved the inconsistent blips for me. Before e85 it would randomly ignore my blips regardless of the long hold. I would do a big stab and the revs would literally keep falling as if I never pressed the throttle. |

I will pull my ABS fuse today and see if I notice any difference in throttle response. Live logging is possible with the OEM ECU. What sort of cable do you have? If it’s USB and is compatible with Techstream then you can log. If your cable isn’t compatible you can get one cheap on Amazon that is. Just search for “Techstream” on Amazon. |

Edit: Okay I see the 2017 has one additional column for engine load at .80. I simply slid the whole table over to the left one column. I created a pastebin for it here: https://pastebin.com/raw/U5GqRfP3 Just copy that to the clipboard, then go into the TIR table for your 2013 ROM and then hit Ctrl+V. It should overlay the whole table with the 2017 values. You will notice the 2013 ROM hardly pulls any timing at all between 4000 and 5200 where as the 2017 ROM pulls up to -25 in that range. It has a significate negative impact on throttle response. Last edited by ermax; 05-19-2021 at 01:17 PM. |

Nevertheless, I have been contemplating flex fuel for a while now. May pull the trigger soonish. Which kit (if any) do you have? Any pros/cons to the rest?

I'm on Wayne's tune (which the TIR table is based on the A01G but with the 4000 to 5200 RPM hole plugged in) but I'm still getting audible tip-in knocks hence wanting to try the 2017 TIR table if the throttle response is manageable. I've attached the comparison below - stock A01G ROM is on right. |

I'm a bit confused by the many variations of the techstream cables, otherwise I would've bought one by now. |

The lagginess on the 2017 table is fairly signification but yeah that tip in knock clicking crap is unnerving. The 2017 fully solved that for me but when switching to E85 I was able to go back to the 2013 table and still not get tip in knock. |

@DiscoQuinn i completely feel your pain with these fa20s. The throttle "delay" as I call it is also my #1 frustration with these cars.
Sadly, it can only be remedied with an aftermarket ECU as I understand. Its just impossible to get rid of the 200ms (ish) delay from off to on throttle transitions with the stock ECU. I guess it does a bunch of calculations before it starts to move the throttle plate relative to your pedal position. That said, there COULD theoretically be another solution, but it'd take some good programming and wiring skills. You could use a microcontroller that directly trsnslates your pedal movement to throttle plate movement while also mimicking the throttle pedal and throttle plate positions that the ECU is expecting. Essentially it would trick your ECU into thinking it's getting an acceptable pedal and throttle position reading. This should prevent any limp home conditions assuming it's coupled with an appropriate remapping of the ROM. Sent from my SM-G991U using Tapatalk |

Many in Japan use the Max Orido throttle controller.
Differently from the others, it has to be connected to the throttle body instead of the pedal, so it can really make the pedal 1:1 with the throttle body. But, shouldn't this turn on the engine light, as there is a mismatched between the expected position and the real one? |

I think that's what the Max Orido box does...
