Some of you may have already heard, but GM is about to offer a PCM harness kit for later model LS2/3/7 motors. This is great news for those of us with later 58x wheel motors.The rumor from an unknown source says the LS2 version, p/n 19166568, will run about $930 from the dealer! That's a smokin deal for what all it includes...

copy/paste




This is a standalone system designed for use with late-model LS Series (LS2/LS7/LS3) crate engines and is set-up to be plug-and-play with the engines as-received from GM Performance Parts – including operation of the latest electronic throttle control, EFI, and ignition systems.

The ECM is an OE unit used currently in many GM production vehicles but the calibration is custom and developed specifically for each crate engine family, so recalibration or tuning is not necessary.

Installation of the accelerator pedal (required for electronic throttle control), harness, oxygen sensors, and mass airflow (MAF) sensor is all that is required – add fuel and power and the engine is ready to run. The controller is also adaptable to any vehicle fitted with one of the engines mentioned. Yes, it comes with instructions. According to GMPP, these controllers will be available in early 2008 with the following part numbers: LS2 19166568, LS3 19201861, LS7 19166567.

Features of the system:

Harness has an OE style fuse/relay center (fully populated with required items). To keep wiring clean and centrally-located, there are additional vacant fuse and relay positions.
A 12-wire bulkhead connector is broken out of the harness and includes user outputs such as tach signal, vehicle speed signal (if a vehicle speed sensor is connected at the transmission), malfunction indicator light, fused ignition power, fused battery power, and oil pressure sensor. A mating connector allows these outputs to be tied-in cleanly without cutting into the harness.
Cooling fan control – system will power a fan when coolant reaches 212 F
Fuel pump is controlled by the ECM
Controls late-model LS series alternators
System Caution:

Be sure to mount the MAF Sensor per the guidelines in the instructions – this is critical for correct engine operation.
Ensure the fuel pressure is a constant 400 kPa (60 psi) with the engine running – this is required for correct fuel control.
Ensure the fuel pump has the following flow capability: Minimum 40 gph @ 400 kPa for LS2/LS3s

That will be a sweet deal.

Anyone know about something like this for the L92?
Or will this itself work?

miguel abizaid

Will this work for a LQ4 or LQ9 engine?....thanks

That should be pretty good setup for the money. Some have criticized that you won't be able to tune these setups. However I would imagine if you get the software from these guys (http://www.mefiburn.com/sc/toplevel.asp?cat=32) you should be able to tune it just fine or any other mefi for that matter even the ones from painless.

So it would probably work for an LS1 swapped to a 58x reluctor wheel also, eh? Seems like a sweet deal, the only thing I dont like is the inability to tune it.

pjtimmer

Can't this kit be tuned with HP tuners or?

how about setting it up with gear to wheel ratio? and et cetera?

Can anyone tell me something more about this harness, tried search but....

I have not heard of someone first hand trying to tune these yet. I should find out the week after next first hand. The tuners I have talked to in person are very confident that at worst case it may take longer than usual, but it can still be done.

pjtimmer

How about using another ECM?

another e67 should work.

pjtimmer

Oke that should solve the tuning problem isn't it?
I happen't to bought an engine with a stock wiring harness and e67 ecm.
The ecm is only from a 6 speed manual, I can have it reflashed right? or can I reflash it myself with HP tuners?

Thanks

What is the difference between the LS2 and LS3 kits?
