Hello all,
I've got a new situation. I have been trying to help a guy out with his tune for a while now. I could'nt really do anything until last night. The vehicle is a 03 RCSB with a 220 cam and bolt on's. Real simple, that is unless you are dealing with a major mail order tuner that has the tune locked. The truck is really nice and has some impressive track times but the drivability just sucks.This guy has already spent a $1k usd on "two" tunes. The first "tune" was for just the bolt ons and then the second was for the cam. What really adds insult to this injury is this "Tuner" has all kinds of photos, track times whatnot on his website of this guy's truck. Well for all the hard earned dough this guy has put out the truck doesn't run like it should.
Finally after many repeated unanswered phone calls, emails, he gets ahold of this guy and this tuners biggest concern is the "intellectual property" of the tune getting out. Maybe he doesn't want any further embarassment but, he agrees to send out another pcm with the tune unlocked.
We got the pcm last night and right on startup we got the following codes. All of the codes reset except the P0200 Injector control ckt.
The attached tune was what was in the pcm. I tried to find an unaltered OS 12593058 to no avail. There are sevral Out of range values that EFI Live detected but when I compared the values to OS 12579405 I couldn't find anything out of the ordinary.
At any rate the truck ran worse than the locked pcm tune(which we still have by the way). We are supposed to send the locked pcm back.
After looking up the code in the service manual it basically says it's a wire, fuse, or the pcm. Seeing how the locked pcm doesn't pop this code or run like the unlocked one I am leaning twoards the pcm.
Unfortuneatly, I jumped right in and linked my v1 cable to this pcm. Does anybody have a ckt diagram for a 1mb pcm?
My next step is to check the output pins on the pcm when the guy brings it back to me. Hopefully it's just a pushed, bent, corroded, or cold solder joint.
Thanks
