S300 socketed and installed problems

Whats up guys,

I just recently installed a S300 in my ECU which was socketed before and had to be desoldered to install the S300.
I installed the drivers and everything like what is stated in the instruction sheet.
Both of the little green lights are on when the ECU is connected to the laptop but I am having a solid CEL
What do you guys think that it might be?
I am from the caribbean so sending the ECU to be tested is going to take too long for me right now.
The first time I uploaded a Base calibration there was no CEL but after the 2nd upload I forgot to disable my 02 heater sensor thats when I got solid CEL which I am talking about.
Can someone help me out???

Can you datalog? Does the car rev-limit at 4000 rpm? Are there error codes when datalogging? More than likely you have lifted some tracks installing the male pins. You will need to check continuity from every pin to where it is supposed to go on the ecu. Also make sure that the S300 is properly seated on the pins. I would highly suggest sending the ecu to us to for testing and more than likely repair.

Do you guys sell ECU's that are already socketed with the male pins for the S300 that I can buy?
I already have the S300 hardware but I might have damaged the tracks you are reffering to.

I did not try to datalog with it yet but I will test it out and let you know

Ok guys this is whats going on right now,

I tried to datalog anto I am getting values in the display tab which seems to that it is datalogging.
I see a red led when I try to datalog on the S300 board it's D2 on the board.
Both D1 and D4 are green when the ECU is connected to the laptop

And when I jump the connector to see what the CEL is I get a solid CEL and when I disconnect the jumper the CEL dissapears.

What could this be?

I think that the issues has been resolved I had a track that became loose when I desoldered the female socket.
Are the D1 and D4 leds supposed the be green when I connect the ECU to the laptop and the D2 led red when I datalog?

In the Fuel trim tab there are a couple of % that I need to put in how do I calculate what the percentage should be?

Can you please advice?

Thanks

ignore what the leds are doing. Is everything now working properly...will it upload, and datalog and do the changes you make take effect on the car?

Yes it's uploading and the changes are also being recorded when I datalog.
Do you have any advice regarding the fuel trim percentages tip in, crank etc?
