ok well the other day i got my rom burner and datalogging stuff from xenocron.com. very good prices and service btw, the owner has been very helpful .

anyway i picked up the willem dual power rom burner. seen here:


now the first problem im having is erasing a chip thats already been burned. the chips im using are the SST 27SF512 chips. i know these are eraseable. when i try to erase them, the burner tells me something about the jumpers and something about 12.75V. im guessing i need the AC adapter hooked up? also it doesnt tell me what jumpers to change or how to arrange them, just that they need to be moved.

next problem im having is with the rom burner burning the chips. now this could be an issue with uberdata or something too but i dont know. ive tried burning a few chips just to test it out and make sure im doing it right. i burned a stock gsr map and disabled the knock sensor (because im using a p28) and disabled closed loop (because i want to datalog). well i popped the chip into the ecu and turned the key to ON to check it before starting the engine. cel stays on. i go to check it and its just solid, great. i start the engine and it almost doesnt want to start, but does without much hassle. idle is pretty rough. revving it up i can see and smell smoke from the exhaust and it back fires pretty good, so im guessing the solid cell is causing it to dump tons of fuel and retard timing. so i try another chip same stock gsr map, except i left the closed loop on and still disabled knock sensor. put it in, same thing.

onto datalogging issues.

im using uberdata 1.7. i first tried to dataloglog with my chip that i had burned for me from a guy on h-t. i have no idea what program he used or what kind of chip hes using so i couldnt really copy the map off the chip. i hooked up the cable and it just gives me rediculous numbers. it does the same exact thing with the cable completely unhooked so maybe its just an issue with my port settings? i dont think its a problem with my soldering job, it looks fine to me. ill let you be the judge









any help is appreciated. also i dont know what the **** is with http://uberdata.pgmfi.org but i cant log on for the life of me. ive tried making a new username for the longest time but it keeps just giving me an error. its so frustrating, cause i wish i could post this there.

 

chip burning/erasing problems are fixed. i had to redo some jumper settings for the erase, and since im using a 512 chip, i had to change the offset to 8000. now my chips i burn are fine

now i just need to fix the datalogging issue(s)

 

bump. need some help with why datalogging wont work

 

PGMFI.org?
Might get some useful help there.

 

yea if i was able to post there. read my last sentence in the first post. ive tried poostin there but i always get an error message when i try to log on

 

is this CN2 pin order correct?

1- Ground
2- RX
3- +5V
4- TX

 

did a write up on the rs 232 gotspeed datalogging board.
the connector on the board is wrong.

here is the link.

******* righteous. looking at my board, and that link they are indeed backwards. but i did it how the instructions say so i dunno... im gonna swap everything around and see if ti works then

 

sure enough that fixed it. thanks.

 

good to hear
