Just got 94FD with select ECU, need help with Transient throttle value
 

Hi, I just bought 94FD with S360 and adaptronic select PNP already on.

Car bogs out or lean out with tip in throttle...
I tried to datalog with MegaLogViewer and saw MAP value does crazy jump on tip in.

I can tune as long as those value is set.

Car is tuned with internal MAP sensor. car doesn't have OEM MAP.

what is the best value for doing adaptive or closed loop mode??
I attached ECU file if anyone has any idea what is the base number for those before I adjust tune.

Thanks in advance!

Map value increasing like that is normal, that's the map prediction portion of the ecu tuning.

You cannot do closed loop or adaptive transient throttle tuning. That has to be done by someone tuning the engine.

I tune cars from 1999 so I think I can say I can tune..
reason why I need to retune is car doesn't run right as far as I can tell from datalog like AFR never be satisfied as I wanted AFR to be. but what I'm saying is MAP value doesn't follow TPS and just jumps at the tip in.
that makes ECU to read totally different cell but is this normal for adaptronic??
never seen this kind of crap before.

I just need values for internal MAP sensor base numbers so I can start from there. or everybody dealing with jumping cell like this??

You can turn map prediction off, and it will probably be more what you are used to using.

Map value won't follow TPS, it follows what you tell it to predict FYI.
