ok I recently installed a stage 3 hondata w p72 in a 01 gsr. The car was running fine for about two or three weeks up until saturday....

saturday go to store, leave store car starts then dies X 4 popped hood checked for any obvious signs...none....girlfriend says try starting it again....voila starts and runs fine.
sunday night driving around and I get a check engine light, so I pushed in the clutch, cycled the key and let out the clutch, restarting the car, cel light goes away.
continue driving to the store...we were in the store long enough for the car to completely cool down.
I start the car, no problems...purring like a cat, let it warm up(listen to bitching and moaning about why do you always let your car warm up from girlfriend...)
we pull up to a red light car sputters and dies....does not restart X 3 so she steers while I push the car to a nearby lot. Same thing I pop the hood check for anything out of the ordinary...nothing, plenty of oil, radiator is fine no leaks or drips..air filter is clean. same thing guy pulls up and says try starting it and let me see what it sounds like....I said "it's not gonna start...." but I fugure why the **** not....sure enough it starts right up and I look like an ***.
Drove home ~30 miles no problems. Checked the cel code and got cel code 13 BARO sensor. Do I need a new ecu? can I use hondata to control the baro sensor? is the obd 2 -> obd 1 wiring harness a possible fault? help me out... TIA

cliff notes: new girlfriend + car = getting a cel code 13 LOL

 

wow thanks for the help

 

I reset the ecu and it was fine for a day, then yesterday I got a check engine light, cycled the key and car ran fine.... I would still like to find out what is causing this...

 

Your ECU is done... send it back to whatever shop you got it from and demand a new one. I chip ecu's and I run mines without Baro, your car shouldn't be cutting off. It sounds like you just have a bad program.
