No 35 each for the chrome trim piece around the headlights. I believe headlights are 95 each... I need one of those too. A drivers side.

 

Just the trim ring's around them.

 

Well, quick update guys.

Truck has been running. Had the radiator fixed, was assured it has been pressure tested and was ready to go, put it back in, it still leaked. Got mad, guy said he would make right on it, but very annoying and I can now change a radiator in 35 minutes from full to full.
'
Chased a tranny fluid leak to a loose clamp that felt tight but was actually bottomed out.

Now for the important stuff:

Truck seems to run well. However, when engine oil temp is low, it is an absolute DOG until it warms up. I mention this because its dangerously slow/borderline will not accelerate At All until its about 80 or 90*. Today I had trouble pulling into a friends garage because of the 2" lip, literally would not go over it. This is something with tuning? It seems overly aggressive in how much it restricts the truck until warm. Its a hazard to drive before it gets reasonably warm, but I'll get kicked out of the home owners association if I let it warm up in the driveway...

Second thing:

Once warm, truck seems to pull well. Don't have a boost gauge hooked up, so can't tell boost at the moment. In the 'Race' tune, under heavy/full throttle, the truck starts to buck (pretty badly) when its gets to higher speeds. 1st and 2nd do fine, but once you lock 3rd, if you have the pedal down, its pulling but starts to buck.
-Got to my friends place and hooked AE. Have a data log from a run like this ^ , just can't post it yet cause friend hasn't emailed it to me, but I will. To summarize what we saw, we are destroying ICP.
-HPOP is a T500, PIS stg 2 175/80 injectors.
-Runs about 750PSI at idle and Ive seen the interceptor gauge read 3400. But with 3rd gear locked and full throttle, dragged it down to 1800, 70% duty cycle (or something, I was watching out of the corner of my eye, but the bar graph for duty cycle was buried in the red on AE).

The bucking occurs about the same time ICP is getting killed. Dosnt buck in the street tune, but just hesitates/feels like a mini-buck. Economy tune has no effect. But consensus seems to be that Low HPO wouldn't cause bucking, more of just bogging/no more go. Didn't really expect a stage 2 do bring the T500 to its knees either, but I can't completely confirm its pump at this point.

Any input on this guy? Thanks guys, I'll post up the Data Log as soon as I can.

Whos tunes r u sporting?

 

Ah yes, Gearhead tunes. Sorry that was important !

 

Is your fuel pressure staying up there?

 

Bucking can happen running the hpop res dry. I've had that problem. Sounds like that pump isn't keeping up to me, had that problem too.

 

You had a T500 at one point Darin? And I never figured a single pump would suck the res dry, have you had that? Did you put on the Riffraff res extended thing?

 

Yes Glenn forgot to mention, Efuel, pressure dosnt budge from 65.

 

Ya, I had a T500, and honestly, I think it was better than the HBJ I put on now. I've been datalogging a lot this winter with many tunes and not having much luck. Should have bought an adrenaline, or better yet duals. Last year with the T500 I hit over 80%dc towing a big hill, with dropping icp. The bucking occurred last year too, so I have put the riffraff res addition on. I'm not saying that is your problem, or was mine for sure, but I put it on to find out because bucking happens with a dry res.


I'd check with your tuner first and see what he says. You got the datalog we can see?


edit: I said screw it and just ordered an adrenaline for mine.

 

Um.hbj ...I thought you liked it? That darn thing is not cheap?

 

Alright guys,
Here is the data logging.

First a picture of a bunch of the graphs from AE



You can see duty cycle rising, and then the dip in the blue line is essentially when the truck bucks. This seems to allow a split second from the pump to catch back up and ICP recovers marginally, then I back out of it (the bucks are pretty violent). In the meantime, ICP has been drug down to less than 2000.

A buddy seems to think this is a tuning issue, some blip in the programming cause duty cycle to drop all of a sudden. Since Duty cycle in an input value and not a measured thing, he figures its gotta be something up with the PCM telling it to shut down for a moment? Anyways, I have the excel file with them graphed individually as well, working on getting that attached.

Here is a picture of the excel data as well.

Seems Im only managing 30 Ibs of boost. And the MAP drops off/goes dead for a split second as well...



Any ideas guys?

 

I think I would talk to your tuner first thing. Send them these graphs and see what they think. It looks to me as though at 3:28:50 the IPR Duty Cycle is at ~50% and the ICP is running close to 3000 PSI. That sounds to me like a pump that is working like it should be. Then for some reason the IPR D/C keeps climbing (though, I don't know what they're calling for for ICP so maybe they're wanting more out of it than that 3000 PSI) and the pressure drops off significantly, then at 3:28:56 the injector duty cycle shuts down. Send these to your tuner and see what they think.

How many miles have you put on it since you got it started? Are you sure it's got all the air out of the HPO system? What is the IPR D/C running at idle, and just driving normally?

 

This run was taken after about 300 miles of driving, so fairly sure the air is out. DC is about 12% at idle, in and around 20-30 % driving around I believe. It's the spike (down) in DC that concerns me the most, almost like its loosing signal for a second or something, which is what causes the buck.
