replacing a 99 me7 car that has a 512kb ecu with an 00 ecu with a 1MB ( did reads after transplant and it reads the 1mb file fine and writes )
gonna do the IMMO  in a few days.

are there any other modifications that need to be done to the ecu?
info on this is very sparse, i tried looking for it.
thanks!

Log instead of guessing Wink

Usually DASHPOT or LSD is the answer.

BGRLMIN does not really matter, because if the torque request is low enough the ECU will cut cylinders.
There's SAWE cutoff delays too though.

Hello!

I’m working on a med17.9.3 from a civic type r fk2 (my own car) and i’m a bit confused about the rev hang issue that all this cars have. When you accelerate and leave the throttle, the rpm doesn’t drop instantly, the ecu mantain it for 1 or 2 seconds.

Investigating a bit i’ve read some people with other types of med17 that they solved this issue lowering the maps responsible for minimum filling in bgrlmin module. Others also talk about lsd function.

Anyone solved this problem in this or any other med17 and can give me some advice please? I attach a complete damos for this ecu if anyone need it for check.

Thanks!!

The S5 ECU doesn't support more than 1389mg/s so a larger MAF probably wont help you.
He's on MED9.

It turns out I'm right to be afraid of fuel starvation.

I colored in the attached logs when the rail pressure is dropping - it is bellow 300g/s hfm reading - easy task for stock fuel system.
Fuel temperature is normal (below 80C degrees), and for this temperature duty cycle for LPFP in KFFLAF is 81%, but because of not enough fuel it is driven to the max allowed 90%.

Is there a easy way to rule out LPFP system for this problem?
I'm pretty sure it is "upgraded" DAZA  HPFP, because now I have dropping rail pressure with les boost and less airflow, than previous setup of this car.
