OverToyed

Let me check the obvious stuff now that I people have pointed out some things I should have checked but I was jumping at shadows and likely over complicated the problem.

Truck is a 99. Yes, heads were re-done when cam, springs, rods and tappets were installed all at once to get proper clearance for that cam. ( Special order head gasket too). Yes, I had to send a YouTube video to the mechanics to show how to replace the tappets without pulling the motor. I'm just down in Parker (25 and Lincoln) and I work in Englewood at 25 and Arapaho. The more I research the grid heaters the more that one is making sense,. One guy posted that yes he can hear the relay thunk but it wasn't actually making contact so that's another one for me to run down.

Yep! Thats me! I called Quadzilla yesterday to see about changing tunings since Edge is really designed for more conventional trucks. I think the broken sensor wire is a good lead for me to try and run down. It might explain the over fueling with the Edge if it assumes 10 Lbs boost if its not working right. So far since the Edge was showing me good, functional boost readings I assumed that information was getting to the wiring harness - but maybe not. I ran down signal noise issues for the TC pretty thoroughly. I even installed the 'Sponge" from ATS just as a precaution. The shudder seems to be dependent on boost and becomes an issue if extra fuel is added due to the load. That's why I suspect compression stall but it just feels like I'm not making that much pressure at that point. ATS thought the shudder issue was insufficient fuel from the stock VP44 so I installed the BD pump since I already had 200k on the stock anyway. The cold start issue could have started here but since the Hamilton Cam was installed in the summer it may have only shown up once the weather cooled. I do wonder if the mechanics who installed the cam botched something and that's where the shudder under load is coming from under load. I'll stick a finger in the grid heaters but yes I do think they are working. I can hear the big clunk when I turn the key on and the "please wait" light seems appropriate. Fuse looks good too.

Hey guys - I could use some help. I've done a ton of mods to this truck and I have two issues - plus I suspect I should be getting a lot more performance. 1. Very difficult to start in cold weather. If I don't have the block heater plugged in I get a ton of white smoke and it's very hard to start until the temp reading hits about 50. This is with the Edge set on level zero. Once it hits a certain temperature boom! It's like a light switch and it runs great though it still smokes (whitish) while the extra fuel burns off. Floor pedal does nothing until it runs, Edge says APP is reporting correct positioning. I can hear the grid heater go 'clunk' when the key is turned on and I've checked the fuse. Fuel is good and I've even added anti-gel though it isn't near cold enough for that to matter. 2. Pulling a load, uphill, 4th in lockup I get a shudder at about 1,800 RPM through about 2,100 RPM. Does it worse under load though I can still feel it on a hill without a load. I have a trans lockup switch installed and If I force it into lockup it makes no difference. I can force it into third and force lockup and with the RPM boosted to about 2,200 the issue is very subtle to non-existent. I suspect compression stall. This seems to have started right after the Hamilton cam was added. Other observations: Heavy black smoke when starting from a stop sign regardless of edge setting. MAP sensor is reporting pressure to the Edge (the edge is just an in-line insertion between the MAP and wiring harness) but if I disconnect the MAP completely it seems to make no difference to performance (I'm wondering if there's a break in the wiring harness and that's why it's over fueling). No check engine light when first disconnected though after fooling with it a half dozen times I now have a CEL that won't clear. Help, guidance, wisdom and 401k contributions gladly accepted.
