the DP fix gets installed in the ECU not near the DP's

Without a tune or the dp fix, you'll have codes and a check engine light. You'll want to keep it in... Or get a tune

Well got the call from a shop (very reputable shop). It's looking like my DME took a shit and may have taken some other shit with it. Hes gonna take a look again tomorrow and make sure a new DME is needed. Not sure if its related or not to the install/uninstall of the bms dp fix. I do have an 07 within the build dates for DME failure.

badfish718 · 12-18-2012, 10:40 AM

Oh crap.

What are the build dates for DME failures I've never come across this...

I switched the yellow wires last night and wound up getting a Checksum RAM ECU code code, when I put them back to how I had them I was still getting the codes. I went ahead and reflashed the map and all codes are gone, hopefully for good.

skatenc123 · 12-18-2012, 01:13 PM

I believe it's build dates 06/07-08/07.

badfish718 · 12-18-2012, 08:21 PM

Well I'm before then at least, and the ECU errors I got went away, but after re-flash I threw the usual P2C7F and P2C6A codes that I've been constantly getting since removing the DPFix. I don't know what it can be at this point as I had no issues before installing the thing, all the pins look to be fine and all are the wires are lined up correct. Yellow with numbers in 19, no numbers in 20. Frustrating lol

skatenc123 · 12-18-2012, 08:25 PM

Hmm those are the codes I initially had. Have u tried completely uninstalling cobb? Driving it a bit to let the battery recharge and then re installing it

badfish718 · 12-18-2012, 09:27 PM

Nope but I will do that once my tank of E30 runs dry

I'm seriously open to all suggestions at this point haha

Blue24 · 12-18-2012, 10:04 PM

Pin 19 straight yellow ,maybe dot Patterns. Pin 20 yellow with a number. Start here and do a 1/7 .

Blue24 · 12-18-2012, 10:18 PM

Sorry ignore the 1/7 part.

19 is the numbered one 20 is non numbered. He already tried switching reversing them.

Exactly, when I switched them I threw some ECU RAM code, didn't write it down, and also the car was idling very rough.

badfish718 · 12-18-2012, 11:29 PM

btw everything that i'm reading on these set of codes point to the o2 sensors being installed in the wrong position on my DPs, but the reason i started this thread is because they are only showing up after the DP Fix was taken off, before that I was not throwing them

Blue24 · 12-19-2012, 10:08 AM

Had this problem myself. For months, almost sold my car it drove me so nuts. 19 all yellow 20 yellow with number. After that all good.

it suppresses the ses light but it doesn't achieve readiness to pass inspections, you need standalone to pass with downpipes in NYS.

i'm sorry but im really confused. when i got the DP fix for the jb3 know one ever said only to run it when your going in for NYS inspection. and in this thread at least one person has said not to leave the DP fix in when you dont need it. so i'm confused what the differences between the jb3 DP fix and the jb4 built in DP fix is. thanks

HermanL · 03-06-2013, 02:29 PM

got the same codes after switching from Jb4 to cobb, cleared it a couple times but it keep popping up. OP did you find out what is the cause? I am FBO but I have never have any cat related codes when I have piggyback.

Thanks to a forum member, I switched the yellow wires #19 and #20 opposite to what it says in the DP Fix instructions and I have not thrown a related code since.
