Title: Chip differance Post by: Bi-turbo on June 27, 2014, 02:56:35 AM Solderd a new chip into a 551C
Car will turn over but wont fire. The chip is AM29F400BB-90SC The previous chip was AM29F400BB-90SI Does the 90SC/SI make a differance??? Title: Re: Chip differance Post by: tjwasiak on June 27, 2014, 03:39:31 AM It should work, maybe bad soldering/bad programming.

Title: Re: Chip differance Post by: f1torrents on June 27, 2014, 11:57:04 AM Did you re-flash the chip to your stock file after the soldering?
You may need to boot mode flash it. Does vcds connect to the ECU? Title: Re: Chip differance Post by: Bi-turbo on June 28, 2014, 05:33:09 AM It was a blank new chip and i solderd it in and boot flashed it but i have found the issue, one of the pads that the chip solders to had broke so the link under the chip wasnt making a connection.
Title: Re: Chip differance Post by: _nameless on June 28, 2014, 06:45:27 PM I opened a amb ecu to find that someone soldered in a new chip, the solder connections looked real bad. Seems they new this too... they used some hard foam and glued it to the chip to push down on it when the case was screwed together. I removed it and replaced it with stock
