383 w/Hot Cam tuning problems (tune/log inside)

[5.7ute]

Sherk, what have you programmed the voltage outputs on the LC-1 to read?

[Goldfinger911]

I notice a few things right off the bat...

....when you say it revs to 1600rpm and thats it... are you giving it more than 23% throttle? According to the log, you're not.

Also, your coolant temp starts at 131 deg C and never moves? Dont know if this is a cause, but it is weird behavior. Is it unplugged?

Also, your Intake Air Temps never move from 57 deg F.

With regards to your fuel injectors... you are running the stock 28lb injectors? What fuel pressure? I realize the stock tune has a flat IFR of 2.9114, but if it is the typical LSx 58psi, you could try an IFR table that looks like this;

3.617188
3.640625
3.664063
3.687500
3.710938
3.726563
3.750000
3.773438
3.796875
3.812500
3.835938
3.859375
3.882813
3.898438
3.921875
3.945313
3.960938

Speaking of the stock tune... does it run better or at least rev better with the stock tune? If so, you may want to start over with a stock tune, make adjustments for the increased displacement, bump up VE by a few percent and then start tuning from there. THats what I did when I first started with my TransAm. The tune that came on the car was garbage... and I wasted weeks dickin' with it before I decided to start over.

[5.7ute]

If the fuel pressure regulator is manifold referenced it will be a flat numerical value.
There is also a bucketload of DTC codes in the log.

[MICK]

Shrek,

You need to Fix some of the DTC's like 5.7 said.

First get the Crank Relearn Done.

In your tune you need to make adjustments to B3605 open loop commanded fuel table. You can't run 14.68 AFR under load with PE turned off.

Something like this will get you out of trouble for now, you can change it to whatever later.
This is from 50 deg c and up.

Sherk...I expect you're running the stock 19lb/hr injectors (poppet or mini....makes no difference...same rating) at the stock 58psi of fuel pressure at the rails?
Mick....if he can't rev past 1600....he can't do the relearn. Needs to rev to 4500 or so (from memory).
All the P0000 codes are phantoms I believe.
I would think the oil pressure is an issue.

[5.7ute]

First thing I would check with all those codes is the wiring. All it takes is one bad earth to stuff up the whole show.

[Sherk]

Well, I had some posts on another board about the issue, and well...

Some sense came into me, I swapped on the IAC and TPS from my old throttle body, and she'll rev now. I had it over 5k. I still get the oil pressure output circuit code, which I don't know what is. The wiring looks good, however it started happening after we pulled the dizzy and re-dropped it. It's possible that we bumped something back there so I'll get that pulled later and double-check all that stuff.

I think now I'll be able to tune the thing properly. I'm going to go flash another bunch of settings into it and take it for a test drive...

[Sherk]

Well, now it's back to not revving up. I'm lost.

[hquick]

I noticed in those logs the TPS seemed a bit whacky. Didn't seem to have any pattern/correspondence to the RPM.
I'd check your TPS connections. Make sure that plug is in properly.
Give it a wiggle whilst it's running and try operating the TB via the linkages at the same time as moving the TPS cable around.
I drove all the way to the other side of town one night to pick up some headers. I got to the guys house and the Burb died.
It would start...I'd put it in gear and it'd die as soon as I tried to accelerate.
As soon as I touched the pedal.
I hadn't long done the 0411 swap and I had needed to extend my TPS/IAC cables.
I popped the hood, unplugged and replugged the two units and it's been fine ever since.

[Sherk]

It's broke. I don't know when I'll be able to get it fixed, so...

Thanks for the help guys, and the ideas. Too bad it wasn't a simple fix.
