Today the 3rd 29c256 chip went bad in less than a year. my car died from an idle in the middle of the road. I cranked it for a minute it started and i held my foot on the throttle but it died right after that. Minutes later, it started and i drove it to my friends house. When i went to leave, guess what? didnt start. So i reburned my tune and it started up, but this time with a solid cel. Not limp mode though.. revved and drove fine. When i got home to check the code, it was solid. I pulled the connector for J1 and it started and puttered and died (440cc inj) but gave no cel. which leads me to believe another chip went bad. The other 2 went during tuning, all of a sudden the car would run like ----, so i would burn a different chip and it would run fine anyone have similar experiances? I need the ostrich!!

Try using one of the old ones again.

i have always used the same ones. 29c256 Do you thinkn i should try using a different chip? Like the SST? When the others went bad, i threw them away. My buddy that works at honda is trying to tell me its the main engine relay... but i wouldnt have a solid CEL if that was the problem.

i forget who said it but i saw yesterday-- "problem after problem, the essence of a turbo honda"

i feel your pain.

Two things I'd check first:

1) I think somewhere along the line your UD .bin got corrupted. That happens every dozen saves or so. Try cutting and pasting your maps into a different fresh Stock GSR.bin and clicking whatever settings you use, save, and reburn with that.

2) Solder joints at the socket, etc, get wierd sometimes. Reflow them with an iron. If #1 doesn't fix you up, I'd be really really surprised if this doesn't take care of the problem.

I tried to cut and paste before but how do you get the option to do it? when you highlight the cells and right click, no copy option is available?? Would a bad burn on the chip light a solid CEL? My zif socket had a bent fin or whatever you wanna call it so i swapped it out with a new one, but that didnt help. It is just weird to me that it would start and run fine, but when i go to restart it- nothing happens

ok. for clarification, what does copying those maps into a stock gsr bin do? Get rid of any bugs from saving/burning?

Tom-Guy

Yeh. The script engine for UD is buggy. The one for Crome is buggy, really, but UD is ten-fifteen times worse. Every time you save a .bin, the script engine recompiles all the speshul functions and sometimes it glitches, because the script engine is fairly complicated and not fully sorted.

It might also be an idea to burn a close basemap from xenocron's .bin repository... those are known good, and if one of them starts your car you know it's a bad burn that's causing your problem.

I used to carry around a spare ECU...now I have two spare chips in the glovebox!
