Dual Innovate Motorsports LC-1's

Both Permament install, simulating Stock O2 outputs. Heater Performance DTC's turned off for front O2's. Rear O2 codes disabled.

Works real nice, but i...

While i dont know the whole story behind U1016. But i do know that multiple vehicle modules can set that code.

I've noticed that i get about 8 U1016 codes immediatly after flashing the PCM. ...

TTT...

Anyone know exactly what format the data presented by the Crank Sensor actually is?

I'm guessing its a hall-effect sensor. But that still doesnt help me interpret the data shown to my...

I guess you could say the sensor was replaced... The whole engine was replaced :D

And yea i think im gonna swap back the sensor out of my LQ4 on it tomorrow morning and inspect the wiring closely.

Ok, so i'm trying to figure out whether or not my CKP sensor is bad, or just needs a relearn.

So, i log the Camshaft sensor data (showing good data) and the crankshaft sensor. And what was...

On the truck fuel tanks, there is a pressure sensor that is towards the front of the tank.

Check that plug, its either not seated properly. Or you forgot to plug it in :)

I've done some thinking on the subject. And i'm thinking its a 99-02 issue, as on my 03, all the HVAC wiring is handled by the BCM which happens to be the same year the clusters and BCM's we're...

Pin 33 on the other connector shows "not in use" on my schematics. Perhaps thats the one?

If it is, i'd jump for joy as i'm thinking of building a fan harness that the PCM can control both high...

Bah poor excuse.... :p


Oh well i can always dream... or buy a TechII... :crazy:

Yep, i have a pushrod lenght checker thingy. Measured it and added preload.

So i got a set of CompCams chromoly 7.400" rods coming tomorrow. Given between the choices of 7.400" and 7.425" i...

Guys at HPT.

Thanks for finally scanning all GM Modules for DTC's. It just saved probably a nice amount of money by seeing that my VSES problem is the steering wheel position sensor. Fixed in...

Oh i did measure them, i botched the math so bad first attempt that it went way too long.

2nd time around with a little help it came out to be 7.408" So i just stuck with the stock lenght.
...

Yea, i talked to Lunati and some other guys with more experience with the GenIII's and i have way too much pushrod. So my valves are not completely seating, so the engine is blowing combustion...

Heads are stock 317 GM cast. LS6 Valve Springs.

But chatting on the Performance Trucks board, i realized im a noob and screwed up the math when i did my pushrod lenght selection. I have way...

Hey all, granted i'm 99% sure i have pushrods that are too long that are creating this problem but i figured i'd ask what others that have similar cams what your MAP pressure is at idle.

Cam:...

Aww... but i want it now... :p


Hehe, mine PCM OS isnt supported yet either. But given the fact that this RTT came out of the blue i guess having to tune it the ol' fashioned way isnt gonna...

Well, after a few more days of investigating. I am convinced the PCM is fried. Its doing the following bad things.

- No longer commanding the ignition relay on.
- No longer commanding the fuel...

Yea it was Ken... i just needed to let the battery charge for a bit.

Now i got some other wiring malady :P Apparently my E-Fans come on when i turn the headlights on. And BOOM P1518. So...

Well, all the wiring is good. TAC module seems to be fine. But the PCM is probably toast.

Its no-longer accepting write commands from HPT. And is not talking to the rest of the vehicle anymore (No...

No im not exactly sure, one the sun rises again. I'm gonna check the wiring via DMM. Hopefully thats the problem. Otherwise i really dont want a new TAC module.

So i just finished putting everything back together today. Put fluids in, and was already to try and start the thing for the first time. But nooooo... My ETC system is not working at all.

- P1518...

Having just read the SD guide in the help file, i dont see anything there that could cause trouble. I do a few things a little different, but have the same net effect as what the help page says.
...

I run SD mode full time, and have done so for nearly a year now.

Basically, i hated my MAF with a passion. My VE Table would be dead on, and no matter how many times i "calibrated" the MAF, it...

Well the dumb thing is back at it... I think i might need to richen up the MAF calibration a bit at idle and see how that works. (i suspect i took too much airflow out)

Ok i think i got it figured out.

NB's look good, ocillating fine at idle.

LTFT's show +12% which makes me go ???

Wideband isnt installed anymore, so i am not exactly worried right now. ...
