LS1 PCM is Shot I bought this car with the engine and trans in it. The engine was built by Turnkey Engines in Oceanside. The engine has a cam and 10:1 pistons in it with no MAP sensor or O2 sensors. The PCM is shot and won't link up to their laptop. I can get another PCM from them for $600 with a propietary tune which can only be accessed by them. For another $150/hr they will dynotune it. This car is a cruiser and I have no intention of racing it. I wondered what you guys thought about their pricing and if there were other options I might use. I looked at the Mallory but they were pretty spendy. I'm new to LS1's and PCM's and have very limited knowledge about them. Any help or ideas would be appreciated.

I was going to get a pic but from their site must be down. Here's a little blurb I found: .......Each engine features our patented 5 Wire Plug and Play Harness that includes a state-of-the-art Delphi ECM with a Turn Key precision-engineered calibration.

It mostly depends on the harness that they used - from that, you can determine which pcm you can use. I would just buy a new pcm for it and get it tuned by a local shop that works with LS-based GM's. For the pcm, check with Wait4me performance - he is on here under that screen name.

Yes that is a Delphi MEFI 4b controller DO NOT USE IT thats my opinion its a batchfire injection system. Its a marine pcm and alot of guys use them in sand rails in fact the sand rail guys are pulling them out and running a car pcm. To much trouble for the price http://www.mefiburn.com/ above you can buy the software for $600 clear the pcm if it was locked and they will give you a LS1 def file tune being a owner of the software
If this as you described above i ran across this abt a month ago on a sandrail. These Dephi PCMs also have no provisions or tables to run a electronic transmissions such as a 4l60 or 80 if you ever wanted to go to overdrive from the research i had did on these. Thats why they are in boats and sandrails

I've known for a while that I was going to have to replace it. I did some research and pricing about 6 months ago. Mallory has MEFI-4's and with the software to tune with it was around $1400. The $600 they want for a new one comes with their tune and is locked.Thanks for the responses. I'll make some enquiries today with the links I was given.

If I was me, which I am =) . I would get a new PCM for your vehicle - Which year and type is going to depend on how you want to keep it running. If It is a drive by wire or drive by cable car. Then either get a harness and make it work, or do it the easy way and talk to a place like Painless ( hope they are a sponsor or someone like them ) and tell them what year PCM, and what sensors you are going to be needing wired up as well as the lengths to each from the PCM.
With a motor that runs on these Crate PCMs, I would assume that you might have to change or add the sensors additionally, but I have seen very few of these Dephli mep4 or whatever they are called- and I havent seen many of them stay running well.
What I am suggesting is going to cost you about the same as what Turnkey wants - I know of them and they have always been way overpriced- and they sell over price, undersold items to people who wouldnt know any different. Convert the car to run like a GM factory car and in the long run the car will run better, be easier to tune and modify- and be easier and cheaper to find someone to do it.

Oh again thanks for everyone's input!
