My current setup is a stock 1995 GSR motor swap in my 94 LS with a drag turbo kit with a t3/t4 turbo on hondata boosting 5 psi with 440 injectors with resistor box. up until a month ago.. the car ran fine.. all of a sudden the hondata started blinking red all the time and the car wouldn't start, so i assumed it was a bad hondata box. so i took out the hondata and put back my stock LS ecu and replaced the 440s with my stock ls injectors (what i ran before i had hondata) and never shifted pass 3k. we took out the resistor box also.. after all this we started it up and the motor bogs like no other.. it seems as though it has to do with the fuel portion, maybe bad injectors, fuel pump, or fuel filter, etc.. but it never bogged before when i had my stock ls injectors and ls ecu in there. Any help would be much appreciated, thanks. and after all this, is my hondata blue box messed up? Also, other things on the motor is just an aem fuel rail and fuel pressure regulator with a walbro 255 fuel pump.

 

is both of your o2 sensors hooked back up? When you run Hondata you only use the primary o2. Did you put your fmu back in? Make sure the lines are correct.

 

we never removed any of the o2 sensors, and i never ran an fmu. i just ran my stock ls injectors and never revved passed 3k.

 

It could be so many things. First of all, make sure that the injectors are completely plugged in. There was another guy on HT that had a similar problem because of this. What is a resistor box? That could be the problem. The Hondata could be the problem, but I doubt it. They are pretty well built. If you had MSD, I would suggest that is the problem. I had a transistor fry in my box after 2000 miles and now it is taking MSD a month to return it after they tried to make me pay when I had a warranty.
On my car, the oxygen sensors are taken off. I don't really know if you need to have them off or on.

 

i just got off the phone with Hondata. They said it's rare that the blue box goes bad, they said since i got the chip re-romed, it could be a number of things, but mainly he said that it could be the solder points on the ecu itself.. bad solder connections and that maybe i have to get them re-soldered. has this happened to anyone else?

 

well if you pulled your hondata out and put the stock ecu in and stock injectors, what are you using for fuel managment with the turbo? You would have to ad like a 12:1 FMU... so its bogging because its not getting enough fuel probably

 

when the hondata light blinks, that means it is not getting a signal from the ecu. check the chip or the interface cable. i had both a backwards chip and a faulty interface cable going from the hondata to the ecu. but that is what the blinking light means, the blue box and ecu are not communicating
