im having a hell of an issue here. i had jsut got a chipped p75 from xenocron tuning, when i put it in my car, i get a solid cel. if i remove the jumper at j1, my fuel pump relay is sparratic, but stil retains a solid cel, so i thought ****, my ecu is a dud, so i got a known good p75 ecu from a buddy,a dn its doing the EXACT same thing. anyone have an issue like this, is it car related? the car is a 2000 civic 4dr wiht the single cam obd2b harness jumped with a obd1 harness. the motor is a obd2a b18b. the car ran flawlessly with my old p75 unchipped ecu, anyone who has any experience in this department PLEASE help me out, thanks.

both ecus start the car, but its in limp mode, idles at 2k and wont rev past 3k. both with the j1 connected and disconnected,


and yes i searched, but i couldnt find a difinitive answer.

 

well im stil messing around with this, now if i take my chip AND my jumper out on my p75, mt car runs fine in stock mode, but if i have wither the chip or the jumper in it goes into limp mode... could this be a bad chip?

 

ok well heres an update, maybe it will help others help me narrow down my problem. with both the p75 and the p72 go into limp mode with my chip and j1 jumped, if i remove the j1 jumper and the chip in either ecu, my car runs fine (but i wont run the p72 in stock mode since i have a non vtec ls. jsut giving you an update as to what my problem might be. i tried a second chip from a previous h22 build, and it still does it. idk wtf the problem is, anyone able to shine some light on this? as another break down, i can run the car fine with stock map, once i put either the j1 OR the chip in it goes into limp mode.. even if i have the chip plugged in and the j1 jumper still unjumped, that doesnt amke sence to me.. anyone able to help a fellow enthusiast out (

 

is there any ecu gurus out there who can shed some light on this?

 

Check and make sure first that the chip is being placed in the ECU in the correct direction...the notch on the chip needs to face the ECU plugs.

Second, inspect your ZIF socket (the socket with a handle) and make sure you havent displaced or bent any pins internal to the socket taking the chip out and putting it back in repeatedly.

Not sure why you are having issues with OTHER chips as well, but we supply two chips with our ECUs, so hopefully you have tried both...email me and let me know if you continue to have issues.

 

unfortunately, i purchase dthe chip kit, so i was only sent one chip. i checked all my connections today with an ohms meter and everything appears to be correct. im not blaming you xenocron, im asking for help, i actualy emailed you my issue saturday, i will not point fingers, i may have messed up a solder joint, i may not have. i dont know, so the best way to figure this out is for me to got step by step and narrow things down.


the chip was placed in the correct direction,

 

here is a quick littel video i made with my camera phone, please ignor the amerature styling.
also, the boost gauge is there because im ready to boost, the ecu is whats holding me up. i have the stock iinjectors in there, but even that wouldnt cause limp mode wiht a basemap set for 450cc injectors would it? iit would jsut run lean (but obviously i wouldnt drive it liek that.) i just wanted to test the ecu.

problem solved, i had a solder joint jumping between two points. thanks for the help xenocron via emails

 

Good to hear you got it figured out!

 

thanks for the help, i just put all the turbo **** in, but i forgot to put a bung for my o2 sensor, so now i got a cel for it itll be solved. but thanks again for helping another honda lover being able to rip on those domestics :D

 

This happens far too often when people chip their ECU without soldering experience.
And for future reference, RTFW!!

thanks, as for my solder exp, i have plenty, i just didnt realize it did the connection jump. but thanks for trying to be a douche.
