Turbo d16y7 in a 93 coupe running a p06 and uber...

I tried 3 ECUs (2 p28s, 1 p06) all have solid CEL with my chip

Tried various different burns and programs... uber 1.66 / 1.70, crome...

Tried no chip in the p06 and still a solid CEL

What the hell else could do it? The car runs fine, but the CEL never turns off as soon as I turn the key on.

edit: tried a stock ECU and it has a solid CEL

i just tried the ECU in my car and no solid CEL!

its definitely the car!

any ideas?

did u jump the connector to see if the light is on for a reason. if it doesnt flash at all i would check the wire to the bulb from the ecu. possibly shorted somewhere and just lighting it up.

 

nah, that was the 1st thing i thought of, but no its not jumped.

it doesnt flash at all when you have a solid CEL because its bad ECU. thing is... i know the chip and ECUs i tried are good.

any other ideas?

 

I had an issue like this once before. I chipped an ecu for my friend's GSR and it wouldnt work at all in my car no matter what I tried (solid CEL) and then as soon as we put it in his car it worked perfect. If you clip the jumper in the ecu and does the stock p06 throw a code?

 

no codes... solid ECU all the time. its like the connector is jumped and it doesnt have any codes so its just solid all the time.

all the ecus and chips work fine in my car

 

bump!

go to autozone and rent a scan tool. that's wut i did

 

if the lights on are you boosting if so have you tried using a missing link ?

 

Check your ecu fuse.

A missing link is not the answer to any problem

some people amaze me on this site.

i actually never thought of checking the ECU fuse... i will do that! AAHHH!!

 

all the fuses are good.... bump!

tried putting a stock ecu in the car and seeing if it throws a solid cel?

 

check every fuse in the car using a dmm. then look at the ecu harness and see if u see any shielding from the wires exposed. could be something grounding out. dmm's are a life saver.

the thing is... theres nothing wrong with the car... it runs fine, its fast, drives fine and everything works... it just has a solid CEL

 

does the cel ever turn off?
like when you have the key in the second position??
i would check the service jumper wiring agian with an ohm meter

 

when you turn the ignition on, the main relay turns on and then off after a few seconds. no matter how many codes you have, the CEL is supposed to turn off with the main relay.

when somebody says they have a solid CEL, it means the light never turns off unless the key is off. this is the problem i am having!

 

someone correct me if im wrong on this one

but if you have a car with no codes and you jumper the service connecter, do you not get a solid cel ?

that was why im asking for you to check your service connector with an ohm meter, considering you say the car runs fine

 

sounds like a wiring issue. get a wiring diagram of the service jumper and chase the wires to see if there grounded anywhere.

if you have no codes, and you jump the service connector, you will get a solid CEL. im going to spend some time with a dvom and see what i can find. thanks for the support so far.

 

bump please
