Would be simple to overlay the LE5 wheel and LSJ wheels, line them precisely and drill the new holes, then recess the new holes so that they fit the same bolts that the LSJ uses.

You mean take apart the motor to change the reluctor? Sorry, but I have no plans to do that. Im talking about all the people who just want to swap a PCM to a better one, not people who want to remove a crankshaft.

Any updates? Interested in seeing if something like this would be able to be transplanted in a saab 9-3. The 9-3 2.0 lk9 is identical to the lsj engine, but is turbo and runs on a Trionic T8 ECM, which has very little support and is crappy lol. I know a lot of sensors would need to be changed to lsj sensors, and would need to add knock sensors, and figure out communication with the rest of the car.

Is there any problems with the cam sensors while doing this swap or are the LE5 and LSJ the same?

You can simply run the Saab B207 with an LSJ ecu & harness, as this is basically the same engine. You will need to swap out some sensors for the LSJ version and you need to ditch the vacuum pump for an LSJ cam sensor. Ow, and change out the coils, as the T8's work differently.
You can run into cam sensor allignment problems, as the saab turbo cams most likely have the hex insert clocked differently (good reason to change for ZZP cams)

Edit; no clue on how the T8 is integrated in your Saab 9-3. Probably quite a lot through CAN...

So would this work on a 2008 l61? Would it also be beneficial to hybrid builds such as an lsj head on and ldk block?

Is anyone currently running this? Seems like a lot of talk about it but no real proof. I want to do this for sure, and I have figured out all of the wiring for the saab swap, but it is useless if I can't change the bin file. Not trying to knock, just thought this thread would be more lively than it is.

Also, assuming each ECM bin file has the same spot in the file for the low ref. crank signal (or if you found where that value is in the lsj ECM), you could essentially copy and paste that value in the e67 ECM and voila, no counting teeth. Just a thought...

This is why no one has done it:

Someone with a Tech II should be able to do the flash as long as they can flash the BCM to match with the PCM, i.e. flash a 2.4 OS and matching info onto all devices, do a key learn, turn off or program the Vehicle Anti Theft, then once everything works together, use the Tech II to alter the VIN back to the vehicle VIN or spend $100 for HPT credits and not worry about it.

E38 pcm is another option, it has a newer OS and can handle larger injectors:

Injector Flow limits with the early E67's (7.9999 g/sec), you need to find a suitable 2008 or later OS with a 15.9998 g/sec limit

Cost at this point:
E67/E38 PCM - $150 on ebay
Wiring Harness - $150 on ebay
BCM solution - $0-150 depending on Tech II access
Tuning - $100 VIN unlock on HP Tuners
Custom OS - $100+ from HPT depending on which OS you get from them, some of these include added costs like 3 bar MAP sensors

will also need:
reluctor wheel reclock
matching crank position sensor (LSJ sensor will not work, it is analog and the newer PCMs use a digital sensor)
Camshaft position sensor (still working on this solution as most of the e67/e38 options use VVT and the sensor is built in on most of them, so we dont have an option, but as soon as I can get a good look at several of the different cars, I should be able to find a way for it to work on an LSJ)

Looking @ $500-1000 initial cost depending on resources
not cost effective...

It is considering the cost to get the T8 ecu tuned. A tune is 350 to 500, then if you want a handheld to change between tunes it is 800ish. Not to mention the tunes are a box tune, not specific to your car unless you want to pay more.

I will research, I am sure there is a more viable option, or a way to make it easier. I am a gm tech after all and have access to a lot of goodies.

You being a gm tech, can save you a lot of money/time, but since everyone with a cobalt can use HPT, it isnt nearly as cost effective for us to swap

Ideally, for similar cost, we could swap to an AEM Infinity EMS and do a layover harness, and keep stock pcm for bcm compatability and gauges, while the AEM controls everything else

There were guys on here that were tuning lots of cars for a long time and blowing them up all over the place. Tenure has nothing to do with ability. A lot of the really good tuners don't spend their days on the forums or on the internet at all.

I agree with Joe, Ive been tuning for a while but dont advertise it, bunches of people here are post ****** and have consistently torn up cars with their "tuning skills" so post count shouldnt be seen as an indicator

I was going to pick up a Saab engine because they are so inexpensive. But I didn't realize the cam sensor was missing and clocked differently. It doesn't seem like ZZP sells cams for them anymore, and the GMPP cost 3x as much as the whole engine. I wonder if it is the same hex as used for the power steering pump that you can order GM #24572945 to have pressed in? I was thinking of running the Saab turbo setup with LSJ harness and ECM...
