Hondata

hi im posting this to possibly see if i can find the cause for why my ecu blew so it doesnt happen again.i have a eg hatch with the hondata obd2b p28 ecu in it with a boomslang 0bd2b-obd1 jumper in it(only running this ecu because i got a good deal on it).brief description of what happened is that i made a pass down the track and the car randomly went lean in third gear so i let off,when trying to download the datalog my relays started clicking like crazy(i have 3,main relay and two other ones for my twin walbro setup)so i shut the ignition off and started to trace the problem.long story short the ecu is fried in multiple places.the circuit board under all the A pins are burnt and also the circuit for the iac.i was told my iac was the problem but i triple checked to make sure i didnt have the purge solenoid plug mixed up and it wasnt everything was correct.i was also told it was the way the pumps were wired that caused it,it is wired as follows...........#87 is going to the pumps,#86 is going to positive signal from the pump,#85 is grounded,#30 is constant power from the battery, what i was told was that the relay was backfeeding a positive signal to the ecu and thats why it fried.im not sure exactly why it happened but i am wondering if it has anything todo with the fact that obd2 ecu's have the three wire iac,originally i assumed that the jumper harness would have the wires switched around to be able to run the two wire iac but i never confirmed it.another problem i was having with the car was a fuel preassure drop during boost whitch is the only indication i have that the problem might have come from the pumps but still dont think the wiring was a problem..........any feedback would be greatly appreciated thanks in advance..................................sorry i dont know how to make the pic smaller bbut you can see everything clearly now

anyone?????
