Car gives map code(3bar) when decelerating when cars cold

Hi i run a reprogrammed ecu. And i have a 3bar mapsensor.
But when the car decelerates when the car is cold(not when the car is on temp) sometimes the cars goes in to map sensor code. And this is also when i have boosted allot (Warm car) en then decelerate.

Does anybody know what's wrong???
thanks Jose

What managment are you running? Some cars running uberdata and 3bar maps experienced this when in deep vacuum with certain 1.6x versions but it was fixed with 1.65 repack3 if I remember right. None of current version have had this problem for a while now, I run 1.66 with a 3 bar and 1.70 even has an adjustable fuel cut so the throttle is not as touchy in the upper rpms.

I'm running an managment thats based on uberdata. But i dont know witch
verion its basted on. I'm going to run hondata soon(when wiredspeedlap starts shipping) But i wanted to know if the problem whas in my software. So that when i'm going with the hondata it will be gone.

At this moment the car also starts very bad but i think this is just becous its to ritch with cold start.

And i have 1 more problem. When i try to keep my eninge at a certain rpm with my clutch pressed in. The rpm's keeps going up and down. I cant keep a certain rpm steady

Hondata or any somewhat recent versions of Uberdata shouldnt give you a map sensor code with your 3 bar.

The starting and rpms going up and down are certainly tuning problems. A newer version of uberdata or hondata and a little tuning could have the car running like stock.
