Right, back out of my meeting now, but do have to get on with some work before leaving shortly.
I got the pics, thanks Nick.
Ignore Ste – Chip is sat in there fine, notch facing the right way.
I’ll be honest too, the soldering looks pretty good, it really is a hard one to tell if there is anything wrong with that side of things. I assume this is your daily drive and this your only ECU? If so, if Merlin can sort you with the JDM Spoon one he has till Wednesday, I’ll next day deliver another chip to try. It’s the only way to rule out the socket installation or a bad chip.
A pic of the other side, without chip would be great. I doubt it was the chip not pushed in all the way. Those sockets are fairly tight and it only takes a little contact to work. Just be careful not to bend or break any pins when you remove it!
I'm real sorry in advance if it’s the chip bud.
Let me know if any more develops.
Cheers,
Rob

no problem Rob - its still throwing up engine management light - so im going to leave it until i can test out another known good ecu this evening. guy that did the soldering has over 35 years experience so id be surprised if this was where the problem lies- i sat and watched him doing it and we went through instructions together and made sure it was right. Took him about 45mins to do so i dont think he rushed it or anything.
will know more this evening and will post up findings.
Dbo my ecu number is 37820-P13-N01.
J-MT which i take to be jdm manual gearbox 2ws.
Says JDM P13 on chip so should be the right one.

still think you should flip the chip around!
hate to admit it but when i installed my chip i had it in the wrong way around to start with and had exactly what your experiencing! engine light on and wont physically rev higher than 2500, just juddering and engine cutting fuel, flipped it around and it was sorted!
