I'm using a 302 based engine, so I will use the cam sync thingy from a 5.0 Explorer. They had coil on plug and came with exactly the same type of arrangement as shown above.

Wonder how hard it would be to adapt it to the LT1 and just ditch the opti.

I think the LT1 conversion is pretty cut and dried.

Its expensive but I'm sure it'd pay for itself in time.

Even if the firing order WERE different, what would it matter? Like swapping plug wires, you'd just need to swap coil leads. . . .

I think you can change the firing order in HP Tuners (EFI Live as well I bet).

For closed LOOP fuel control, the PCM controls banks of cylinders, either it makes richer, or leans it out.

When PCM see's a lean condition on Bank 1, originally cylinder 1,3,5,7, it will add fuel to all those cylinders independent from what BANK 2 needs.

If you rewire you're injectors and now an injector originally on bank 1 is now mixed with some originally on bank 2, when the computer goes to adjust fuel based on oxygen sensor feedback, some cylinders are not going to be adjusted.

I believe the firing order function only is for MISSFIRE diagnostics. I don't believe it actually changes the order the PCM fire injectors/coils. There have been threads about this before.

Unless you can tell the PCM which cylinders are BANK 1 and which are BANK 2, its going to be hard to do CLOSED LOOP when using a LS1 operating system on other engines.

EFILive has this covered. Notice the difference between early small block (L31) and gen 3 small block (LS1). Copy/Paste, you're done.

What is the Vortec 454 crank sensor output? 24x?

CMcCarthy

I've since scrapped this idea because the class I'll be running now allows FAST systems, but this has really turned into quite an informative thread.

4x crank trigger
1x cam trigger

identical to the vortec 5.0/5.7 96-99 or 02? in express vans.

Hmmm. Interesting thread, probably not something I would've thought of personally, but with the right inputs, it seems like it should work...

SO What od we like from having this to work?

im trying to gather info on swapping a ford ecu on an ls1 for a friend of mine at his machine shop... seems as though this thread gave me some valuable intel that just might point me in the right direction

btw... nice to see a familiar face sws

I have them running Northstar's

I also have the 0411 calibration completely mapped out all 4400 + lines and I edit and or build my own VDF's

I know this thread is older than dirt, but does anyone know the exact signal output that is coming from the ford TFI distributor, going to the computer? Like an older chevy HEI, or TBI style distributor has an 8x cam signal (which is still 4x crank) is a ford setup the same way?

Hi first time posting.

Looking for help as I'm going to be using a 0411 ecu to run a sbf cleveland, the setup is with ITB injection
I already have the ecu with vat delete etc. Have 24x reluctor which I'm fitting the front pulley.

Questions- first one- which tooth is the crank pickup pointed to on tcd ? I did find a post on another forum someone doing it on a chrysler 440 but some more pics or info when the sensor is @ tcd would be great , second I'm hoping to use a MDS cam sync https://www.holley.com/products/igni...nc/parts/85211
I see the ls1 uses a high low trigger- halve moon to trigger , so I'm unsure if the msd cam sync trigger will work and more so how to set it up - video of setup the msd cam sync
From this thread I got some good info, like if I setup my ford on number 5 cylinder my engine firing will be the same as the LS

Cheers Jason

edit some info https://board.moparts.org/ubbthreads...pe/thread.html

Anyone know if the crank sensor for the 24x is orientation critical ? 'Im trying to mount sensor on the front of the engine and if I put the plug facing forward like it is normally mounted that puts it in line with the alternator belt
I could maybe face it so the plug faces backwards but that may still be a problem, preferably I'd like to face the plug up or down

It's a dual track sensor correct ?

Any help would be great - thanks

zg knightrider

So no one ?

What if I use a crank position sensor from a 7.4l would be a better fit

The crank sensor mounts into the LS engine block where its in close proximity to the crank reluctor wheel.
