im lost as to what to try. i try checkign the cel but its a solid code. which i think means a faulty ecu if i remember right. but i used this ecu in a freinds car and it worked perfectly fine. could it be soemthing in the program i have? there was a 2 step set up in the bin, but that was at like 3800 rpms.

 

solid CEL does indicate a faulty ECU. You say you tried this in a friends car and it worked fine. How long ago was this?

 

3 months ago or so. it was in a civic with an EX swap, running a stock p28 program. now i have just a basemap in there for my ls vtec. but i tried runnign a stock p72 program to, and same thing..

 

ah, i missed the part where you said you had a 2 step in the .bin. Obiviously this is a chipped ECU. check to make sure the chip is facing the right direction.

 

it is laying in there with the little outline on the ecu board..

 

thi9s is really starting to bother me..

 

Could be a bad chip man. Reburn on another eprom and try it again.

 

tried a freinds ecu with my program on it and it wokred perfectly. so soemthing is messed up in my ecu. but... it worked fine in a freinds car not to long ago...

A bad ECU (code zero) is indicated by a CEL while it's running, but the CEL turns OFF when you jumper the SCS connector.

A good ECU with no codes stored, the CEL comes on solid when you jumper the SCS connector.

 

ok, i think there is a short in my ecu somewhere.. this really sucks. no idea how to find where its shorting.. i checked all of the connections inside, where i soldered everything, etc. and now its throwing a code for iac, vtec pressure, and TPS

 

when i jump the harness to get the cel, at first when i turn the key to run, it will start blinking the codes, then soemthing clicks, the cooling fan coems on for a second, then a solid cel.. soemthing is definately shorting out..
