Can't throttle after recent tune upload
Hello, I have a k20z1 turbo in a 92 eg hatch that I made awd with wagovan parts. I drag race the car and trailer it to and from. last weekend at the track my tuner made some changes and I uploaded them. shortly after that my laptop would not communicate with the kpro at all. Everytime I tried to log it the kmanager would freeze and give an error . I made one pass and it acted perfectly fine. Later that night when loading the car it acted like it was starving for fuel. the following day it acted the same. In detail it can idle but as soon as I give more than say 10% throttle it dies down rather than increase rpm. I have a datalog of this and to me the tps and map sensor both seem to be working. I seen that the wideband is functioning as well. I'm pretty stumped as to what could be causing this. I thought plugs could has been an issue with how rich the car idles (vtec lock pins) so I changed the plugs and it didnt make a difference. I am certain I have fuel and proper pressure. I updated kmanager today and that fixed the communication issue. I'm very stumped as to what could be the issue and would gladly provide datalogs. Its a pretty fresh build so I cant say something simple hasn't happened all the sudden but I can say I have a complete rywire harness and dc5creations charge harness. My voltage is almost 14v while running too btw.

Re: Can't throttle after recent tune upload
After studying my log again, I noticed that after initial start up the map input stays at -14.6" psi no matter the throttle position. Also noticed that the afr leans out hard with throttle so I believe I have a bad map sensor. I ordered a new 4 bar sensor and will update if it fixes the issue. If anyone has more ideas on whats wrong feel free to share.

Im having a similar issue with my k swap I just completed. I tried three different map sensors and checked my wiring and everything checked out fine. The car idles totally fine and the map gives an initial reading which freezes and never changes. Any gas and the car leans out and dies. Curious to see if anyone has any ideas for the cause.

What is the serial number that is on the K-Pro board inside the ECU?
