Hi there!

I have a c70 LPT and i have removed the ECU so as to put a tuned chip. After the whole prosedure (desoldering the old chip, putting a socket in the board and placing the new chip) i have placed the ECU to the connector and the car didn't start. So i thought that something wrong is going with the new chip. I then unplagged the ECU, change the tuned chip with the stock chip and the car started. I let it warm up for a few minutes and i turn it off. Then i tryed again the tuning chip but the car denied to start. After a few trials i decided to go back again with the stock chip so as to have the car in a "working condition", but the car didn't start this time even with the stock chip. Has anyone a same experience with changing the chips? I have looked some fuses in case that were burned.Also i have to inform you that i have a volvo special tool to plug and unplug the ECU from the connector (in case that you think there is a bad connection in the ECU connector). What you suggest to do? If there was a problem in the tuned chip would it be a reason to damage some other electronic? How can i be sure that the ECU is in good working condition?

Thanks,
jim

ok! i found the solution. The bad connection was between the chip and the chip socket. So for everyone who is interesting in chip tuning, you have to pay a lot of attention in that part.

Thanks,
Jim
