solid CEL, no codes

solid CEL, no codes
i have a 93 ex no turbo yet. im using uberdata and i chipped my ecu myself with a kit from xenocron. i used a completely stock p28 map just to eliminate any of my programming errors but when i start the car i immedatly get a CEL and if i try to check the codes it just stays on steady. i am assuming it is a bad solder or something like that, but i have looked it over numerous times and it all looks good. any ideas?

Re: solid CEL, no codes
can any of those parts that came in the kit be in backwards or do they go either way? i think im gonna check for bad solders again and if that doesnt do it then i will try burning again
EDIT:: i ran my soldering iron over every solder i made, added a little solder to a couple and reburned the chip with no luck. can anything else cause the same problem?

i have tried making three different maps and burned each one a couple times. i always check to make sure the chip sits like it should in the socket. also, is it normal for the car to run even with the chip out? i figure its some sort of limp mode cause its super rich

Re: solid CEL, no codes
ok, i downloaded another bin file and it ran my car w/o a CEL. only problem was it was for 450cc injectors so it ran like ***, but no CEL. now i have to figure out why i cant make a completely stock p28 map that will run w/o a CEL. i am using uberdata with an older willem burner and an sst27sf512 chip. i am just trying to learn this stuff with as little variables as possible and then slowly add the variables so i can tackle them one at a time. once i can make a map that works stock then im going to add my 450cc injectors and then when that works i will add the turbo
