V6 ecotec 3800. Tuning ls1 Pcm
V6 ecotec 3800. Tuning ls1 Pcm
I have done 99% of the wiring
just a little unsure on est bypass wire & Crank signal wire
Do i hookup Crank signal wire to 18x Crankshaft reference or to Crankshaft Reference out from DFI Module???????
Next step Is the PCM...
Has anyone modified an LS1 Pcm to run a V6 Before..
Need to know what to do
I have Hp Tuners / EFI Live & MongoosePro
If anyone has worked it out please share this info with us.

Re: V6 ecotec 3800. Tuning ls1 Pcm
so you want to run an ecotec on a LS1 PCM ?
crank and cam signals are going to be the main issue, need to make sure you have the right signals to keep the LS1 pcm happy, i think the rest should be fairly straight forward.

No matter what the question is, the answer is always more horsepower!

Re: V6 ecotec 3800. Tuning ls1 Pcm
why? the v6 pcm is quite capable.
Re: V6 ecotec 3800. Tuning ls1 Pcm
Reason being...Just about any tuner can tune an ls1 ecu with Hp Tuner & Efi live these days...
Very easy to upgrade a tune from a Maf tune..to Mafless...2 bar and 3bar.

fair enough, seems alot of trouble to goto just cause a tuner can't use the stock system.

this guy has done it
thats a 5 liter, not a v6. I would hazard a guess that loom isnt using the factory ignition module. hes probably tapped into the hall effect directly and is using a single ls1 coil driven off the pcm directly to fire into the dizzy. seeing as how a v6 has no dizzy, it would be more difficult for you.
at a guess I would say you need to throw away the DFI, and run the crank sensors directly to the pcm, then run a set of 6 ls1 coils directly off the pcm. will be interesting to figure it out.

Ive got a feeling he has done it, or soneone anyway. Its on the street commodore forum.
Re: V6 ecotec 3800. Tuning ls1 Pcm
He guy has also done one to suit a V6 running the std DFi module type ignition system
Re: V6 ecotec 3800. Tuning ls1 Pcm
doing a bit of a google. found the v6 one now. the ultimate converisons guy says on one of the forums that the bin is modded (possibly o/s hack??) and the pcm is physically modded as well to acheive this?
edit: looking at it again. id be willing to bet hes either modded the hardware of the pcm and / or made his own programmable igniton interface to talk between the ls1 and DIS module. IE: the ls1 pcm it thinks its receiving the 24 tooth crank signal and driving coils directly but the DIS module thinks its its receiving the ignition control signals from a delco.
