Of course. It sounds so obvious when you say it.

Add real octane booster and see if it goes away?

If the pid will display a voltage range, it will probably work as long as you can turn off it's normal function. But does the ecm have the internal...

I get the part numbers mixed up but I've not been able to get analog out from the CAN version. I had to buy the non CAN version also for the older...

Yep, thanks -- that's what I had just figured out. The "switch" ones appear to be off the table. :(

Turns out the fluid pressure switches are just that -- switches. They're either on or off, and they use ignition voltage. Thinking I probably can't...

I think you are correct. I've been comparing the cam timing between the Iron and Aluminum blocks, (NA and Turbo) and the both AL use lots more ...

You are going to have to determine which of those are looking for a 0-5v signal or something similar vs a discrete on/off or some particular value...

And, from the 2000 Service manual, here's EGR: Blue Connector: Pin Wire Color Circuit Description

did you ever find a solution? im currently going through the same thing. After a few tries, the vcm did pull it up once, froze at 12.20afr while the...

Found the equivalent diagram on the PCM side: <-- PDF with complete 2002 F-body pinout! Red Connector: Pin Wire Color Circuit...

Found this in the factory service manual, showing the pinout of the automatic transmission wiring harness: Here's the engine-side of the...

cleaned the map re ran pcv line different pcv running richer now

Also found this: https://lt1swap.com/99-02_vortec_pcm.htm PRND A / B / C seem promising. I assume those are the same as the "transmission range...

Found this thread at PCMHacking.net, which discusses 0411 pinouts, but is not F-body specific. These two were consistent across both platforms...

Well damn looks like I learnt somethin today.

For what I can see, the injectors are about what I need. Now, tuning settings are a different thing and the next step. INJ Size #/hr x #INJ's / ...

Okay got a stock 03 tahoe tune same exact model as the one my friend tuned and after comparing them i some what understand alot more. Sorry for the...

Awesome explanations on MAP/VE from the both of you. Makes a ton of sense. Question I had about timing in relation to power and the ignition...

does your customer page say you have any credits on your device? that is the first thing to check.

Anything after I failed the maf is after in new injectors and intake swap. Let me go back through that whole thing I’m going to put the other map...

Thanks for that.

have you tried burble logic ?

would you please share it ?

That'll make a good comparison. Where do I find it? Would SD 15 in your first post work? If so then yeah that's a reasonable VE table, and the...

That was correcting against the ve before I touched it at all
