S200 hondata - P72 Ecu Socketing Trouble
Posted: Thu Nov 11, 2004 7:32 am
Ok, i have this p72 i bought, supposedly ready to go, just plug in the box and the rom and should be good to go. It wasnt.
Im in Raleigh, Nc, and turbo tune down in greensboro is an authorized dealer/installer/tuner. A friend of mine knows Mark at turbo tune and so i drove down there last night and we tried to figure out what was wrong for about 2 hrs.....
Heres the situation:
94 usdm p72 pre-socketed by a supposed good source, but id rather not get into that or it might get vulgar....
When i got it i put in my rom and plugged up, tried to start and got limp mode with the s200 blinking.
So i called the company i bought the s200 from and they said they accidentally burned me a p28 basemap. So, i went down to greensboro to get mark to burn me a p72 basemap, it still went limp/s200 blinking with the new basemap.
Then we went over and resoldiered all the previous rom socket connections, and it still went limp/s200 blinking.
So then we looked over the 4 pin connector soldiers and they looked ok. Still limp/s200 blinking.
Then we figured to try it in stock format, so we burnt a stock p72 program to the rom and cut j1. Plugged it up and it worked fine. No cel, ran perfect.
Reconnected j1 and burned the hondata h22 basemap to the rom and it went limp/s200 blinking again.
Tried another s200 box that we know works....still limp/s200 blinking.
Desoldiered the old 74hc and put in a new one. Still limp/s200 blinking.
j12 is cut, j1 is connected, and all the soldiers look right now, we are stumped.
Anyone have any input?
