okay this is how the problem occured. i just installed a sk2 im and threw my p28 with a jun chip in it. Then my car ran like ****, threw like 3 codes. I didnt feel like working on the car anymore, and i was just gonna check it out another day. So i decided to just but my stock obd2 p72 chip back into the car (if its not gonna run right, might as well save some gas for the time being) and then all the codes were gone.. My car was perfectly normal.. So i thought maybe the Jun chip was was too rich, running in open loop, so i went and ordered a J's racing hybrid chip(runs closed loop). And today i went and installed that chip, and it still runs like ****. threw some codes is in limp mode. Wont go over 4k rpm. Anyone ever experience problems like this??
to summarize it: intalled sk2 im, put my p28 chipped jun in, threw codes run like ****, change jun to J's hybrid, still ran like ****. what are the possibilities?

 

if you were unable to rev past 4k rpm while driving then the issues is with either the chips or ECU.
-chips either wrong program or inserted the wrong way or simply lost data (static)
-ECU could be damaged or not chipped properly.

 

let me try flipping the chip. maybe i inserted it wrong.

 

okay i got the codes 3, 21, and 22 with the Jun chip. And with the J's hybrid i get a code, 0 (0 is when it stays on, and not blink right?)

 

what do u think guys?!?! Im just confused because only the J's racing chip gives me a ecu defect code, and the Jun chip gives me the Vtec and map sensor code. And my stock OBD2 wont give me any code. SOmeone help me out!

 

3 is map sensor, is it plugged in and if so did you mix it up with the TPS. 21 is the Vtec solenoid and 22 is the vtec pressure. make sure they are all plugged in, as for the J chip its bad, solid light means the chip is no good. hope this helps out.
