LS1 0411

Being an OHC motor the 4200 calibration likely has spark/ve tables at higher rpms than the 3400 calibration.

Reading a bit more the 4200 trigger has 6 notches 60* apart and a 7th 10* after one of the other notches. The cam trigger has 6 notches each of a different size to uniquely identify each cylinder.

Can't find info on the 07+ 4200s but I believe the triggers changed that year.

interesting idea, I don't see myself using it, but someone swapping a 3900 might.

also, FWIW, the TB PCM is a completely different form factor compared to the typical 60V6 PCM, for us who have done engine swaps, NBD, but for the rest of the 60V6 world it's not as helpful.

also, FWIW, here's the 4200 PCM PN

I looked at a 2002 trailbazer file in tunercats and in the switches ther was an option to disable the ETC how that would work to drive the IAC on a non dbw setup not sure that is a P10 ecm btw

interesting. I guess the next step would be to find a vehicle using that PCM with a cable throttle (good luck) and get a pinout for it to see where and how the IAC is wired in.

I do remember awhile back when monodax was still up a guy was wanting to run a corvair motor off a 0411 pcm. I have a 2002 camaro LS1 i modifies my tune in the engine platform to a v6 and changed the injector bank assignment and still ran on 8 cyl just fine so there had to be something in coding to make it a 6 cyl.


On the other hand i had a 1998 5.7 vortec truck that the guy got a 4.3 pcm i shut off the vats and didnt even look at file being he told me it was a v8 file when i started it ran only on 6 cyl. I flashed a v8 file in it and it was good after that.

I'm thinking(been wrong before!) it would probably be easier to start with a V6 bin file, like the 2002 S10. I have a .cal file for one, but I can't upload it from this computer.

I has a 2002 s10 4.3 file the ve tables and spark tables go to 8k now figuring out the COP deal

[ericjon262]

you don't by chance have a 2002 aurora 3.5 file handy too do you?

Hey I just noticed that the equinox 3.4 PCM is supported by Hptuners. IIRC that engine is very similar to the LX9

EFI live does too.

Huh what kind of trigger wheel do the 4.3s have?

4.3's use a 3x trigger,
I've found a parts diagram w/ a shortstar crankshaft, it appears to be a 24x sensor. which a member on gearhead EFI claims to be correct.

I feel like it would probably be better to start with the LS1 programming, and reverse engineer it for V6 use, as it already offers what we desire.

playing around with tiny tuner today I noticed a setting for crank sensor resolution with options for 3x/18x(3800) 7x/24x(3x00) and 24x/24x(Shortstar) is there a similar setting using an 0411?
