Sorry I missed your call this weekend Beer. Hit me up a bit later if you are still having issues and I will see if we can't clear them up.

Something is still not right, here are some brief logs.
The EGR records my fuel pressure...I dont think it is tune related as I the first two logs are COS 5 and the last log is a good tune from August.
Going under the car today to look for burned O2 wires or exhaust leaks or anything blantanly obvious...
Notice the erratic MAP value ???

Seems I am not getting any spark, could the plugs be fouled, that bad from trying to start it like it was? Going to pull them today.

OK pulled plug #3 I suspect all are the same...Howard got me focused on looking for Spark, as I could certainly smell fuel.
I hope this is the culprit...Probably 800 miles on this set of plugs.
Possibly the car was to rich as Joe pointed out (the rough idle) and then it got the the point where the plugs are so fouled no start??? Hope so this would be an easy fix

I agree, MAP looks erratic... check MAP sensor o-ring and check for other intake leaks.
After you pull the plugs, also check the plug wires with a DMM/ohmmeter to see if they are all the same.
Yes, plug tip shows carbon fouling (can't even see the ceramic).
Up and running (an older tune not COS5) it was the plugs. On to COS5 again

Here is what I want to use next, its a combination of feedback from Joe, and Lorenz.
Any feedback on this tune? Being there are no out of limits it should work first try? Also changed table 3647 per Joe.

Looks like it should work... it will now idle closer to 14.5 so you shouldn't get fouling.
Its works! Thanks guys!
