thought i would help spread the word...

i, for one, love the DIY crowd, and will be interested to see if we can run these on 660s.

the thirdgen EFI world come up with some cool stuff, I just wish I knew more about what was going on in there ( how to tune!)

I think it's closer then you think. 2001-2002 4.3 V6 vehicles use the 0411. I'm going to start doing a little more digging, this could be interesting.

still looking at it, but I think I may have coil per cylinder wiring figured out for a 0411 V6, software will def require changes though.

Back in the day I knew of guys that were using LS1 Edit to tune their 4.3L S-10 pickups. It would be interesting to see what it would take to successfully run a 60v6 on one of these PCMs

[ericjon262]

I don't think it's as far fetched as many would believe. I'm looking into it, along with the Short* programming, for possible coil per cylinder ignition, and higher RPM capability.

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

haven't really dug to deep into that yet, I'm still looking into the short* programming first. the 4.3 s10 programming doesn't appear to be as well supported as the rest of the 0411 family tree.

I'm trying to get my hands on a short* .bin file so I can see how well supported it is VS the 60V6 programming.

According to all data the shortstar uses a 2-in-one style crank trigger. Possibly similar to the 3500? But since shortstars are rarely modified vs. 4.3s I doubt there will be much tuning support for them. Does Hptuners support them?

However what may interest you is that the vortec 4200 uses a 7x crank trigger and COP ignition, and there is some aftermarket tuning support, although I'm not sure how well supported it is either.

Iirc the vortec 4200 cam signal is different from 3x00 but you could always run without SFI.

The 4200 PCM also supports cam phasing

[ericjon262]

Robertisaar said that it looked like the short* was supported in tiny tuner. won't know 100% until I have a .bin and try it out.

I see the short* modded about the same as the 4.3, just not commonly in the car. my understanding is that they were popular in dune buggies for a while.

I'd rather not deal with DBW throttle is I can avoid it.

also, the LX5 does use a trigger similar to the 3500, but with a different tooth count.

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.

that's identical to the classic 60V6 DIS setup...

Makes you wonder how compatible the other sensors are... I would bet the DBW throttles are compatible as well.
