Hi Everyone, Does anyone have an EPROM image for a 2F (I have a 1977 FJ40, desmogged) for use with a Chevy 4.3 TBI conversion? Here's the problem I'm having: I did the conversion last summer and the cruiser runs ok with the original chip (but not great). So, I wanted to improve the performance with a properly tuned chip... so I got a blank EPROM and burner, and asked TomQ, who did the great Tech Link on the TBI conversion, for his EPROM image, which he generously supplied. I recently had the chip burned by someone here in town and the programmer has verified that the chip matched the image, but when I put it in the Land Cruiser (we tried this twice), I just get the fast-blinking check engine light and limp home mode. So, I thought that perhaps the image had gotten corrupted in the email or something, and Tom was kind enough to email me another copy, and it burned with the same results. So, it seems like there are two possibilities here. 1. The image is bad (which doesn't seem likely becasue Tom is using it) or 2. There's some problem with the process of burning it to the EPROM. I don't see how this could be, considering the fact that the chip verifies to the image. If I put the original chip back in , it still runs fine, so I'm ruling out a problem with the ECM or sensors on my cruiser. Since I can't seem to narrow it down any further (and can't figure out what the problem would be with the burning process), so I'd like to try a different image. On the other hand, if anyone has an idea why the program might verify fine but still not work in the ECM, please let me know! Any help or ideas would be appreciated - Matt PS - Thanks for your help Tom!
