LY6 throwing codes please help Ok i am going to describe what my motor is doing and if you can help me figure out what is going on i would really appreciate it. First off, the tach is way off, and the speedo will just peg all the way out as soon as u put in drive and take off. then it doesnt want to idle, and if you give it over half throttle when it is in drive it goes into safe mode where you cant rev it at all
The 2 codes it is giving me are P0606 ECM/PCM Processor
and P0011 Intake camshaft position timing over advanced (bank 1)
the motor has a comp cam with VVT, and the tune/harness was done by speartech
thanks

I'm going to be going the same route and someone told me that I need to have the tuner tune my tach for an "8" instead of a "4" which is the way new tachs work. I don't know if this is part of your problem, but may get you started. Apparently the tach signal is different for new cars than for old classics.
And also, did speartech tune for the cam? I've been told that you really can't do that mailorder. I will be getting a "get it started" mail order tune and then drive immediately to the dyno to dial it in.

called speartech and he doesnt really know, so is there antbody that can help? From some of the reading i have been doing, it could have to do with oil pressure, and if you change pans(which i did) you have to run a specific filter to get it to work. any body ever had this code before?
U jack w/ the oil psi relief?
Did you change cams and use hi pressure springs?
Cam degreed in?
Cam timing limiter mod done?
Wiring/plug problem?
This any help?

Tach output needs to be calibrated to your tach. VSS needs to match whats in the tune. Sounds like its set for a T56 reluctor (17tooth) and running a 4L60E reluctor (40 tooth) so you bury the speedo when crawling around the parking lot

Hey What fixed this? I have an LY6 an I get the P0606 code as well.
If i really baby it I can drive around the block but step on it at all, or jump off it quickly, light mil comes on and engine drops to idle, gas pedal has no effect on engine. Little better when cold. PSI Harness and ECM programming came from PSI. Code looks like an internal ECM fault, like I need a different ECM, Not sure what to do from here, ECM came as a package with everything else. 2009 LY6/4L85E ECM, TCM with 10K miles. The cam, intake, fuel rail and injectors have been replaced with stock units off a 2010 camaro. VVT is still installed, MAF is the card stlye, ls3 alternator.
If anyone has an E38 that would work or a cure for what my has please let me know, I live near Tampa

Here is what I found while doing research on the P0606 code.
In all likelyhood the PCM / ECM has failed.
"Possible Solutions: As a vehicle owner there is little you can do to fix this code. The most common fix for a P0606 code is to replace the PCM, although in some cases re-flashing the PCM with updated software could possibly fix this. Be sure to check for TSB's on your vehicle (Technical Service Bulletins).
In all likelyhood the fix is to replace the PCM. This is generally not a "do-it-yourself" task, although in some cases it may be. We strongly recommend you have a qualified repair shop / technician do the work, one that has the capability to reprogram the new PCM. Installing the new PCM may involve using special tools to program the vehicle's VIN (vehicle identification number) and/or anti-theft information (PATS, etc.)."
So it looks like you either re-flash the ECM or buy a new one and have your program installed on it.

Lloyd's Performance in Jax, Fl did the cam, He seem to know what he was doing and had done several before so I feel pretty confident about his services. Oil pressure seems fine, never goes below 25 and bump it a touch above idle its just below forty. Tune on PCM was done by PSI, I've email back and forth but waiting until tomorrow to call. His feeling are to get a replacment PMC and try it, but I hate just throwing money at it when I dont know whats going on. The PCM came with the eng/trans and only had 11K on it, so it should work.
I also hate to jump around so I plan to stick with PSI until we hit the end of the road, PSI- Jon is very knowledgable but also seems very busy, This is my first and only build and have already asked more than my fare of questions.
