It was the map file it was corrupt got another basemap and it runs strong now

It was my tune file I found a basemap file from a user on here used his file and set it up for what I'm running and car pulls strong now

On the laptop map sensor reads -22psi but on the mobile app it reads 5 psi boost , on the old hondata app map reads correct

no not yet i did a new map and just reposted a new map file and data log

as vtec engages feels like loss of power

It appears to be related to VTEC engaging. Check your grounds, especially the thermostat housing ground. yeah man all grounds are good i have the grounds at the thermostat along with the coil on plug ground there also in was thinking vtec related i have powered the solenoid and it sound like it is ...

at wot i cant get past 4500 rpm on about half or so i cant get past 4500 rpm i attached the data log and calibration

will try that today or tomorrow thank you

If I unlug the map sensor it goes straight to max boost

The factory map on firewall was working fine just before I pulled the motor to turbo . The map was never taken out it was left in the car it has its own factory wiring straight to ecu

vehicle - 1990 accord
engine - is f20b using stock map sensor on tb
tried the factory map on firewall reading 20 to 22 psi boost same with tb map sensor tried another tb map sensor same thing car will not start and run its flooding out
