Alright, sounds good. I will just pick a used motor and tranny from a local yard then (and make sure it is 91-95). Thanks for answering my questions.

Thanks, I knew there were some changes in '96. Do you have any idea what those changes were? If I find a low mileage 4.0L that is newer then '96 for a good price would there be many points of concern?

I am currently looking to swap out my 4.0L and AW4 tranny in my '95 XJ for used units. (Motor and tranny were shot when I purchased). From what I understand the AW4 tranny can be from any cherokee '91 and up (due to the 23 spline shaft that was introduced in 91). As far as the 4.0L can I use any...

Really? I hadnt heard about any reliability issues with firing the coil right from MS. . .interesting. I'll have to do some research

That was my plan. I was/am going to go to the junk yard and grab a bunch of connectors from other cars. Then I would be able to quickly swap from completely stock to MS by unplugging one connector and plugging in a second. As far are the direct ignition rail. . . I am using the stock ignition...

Alright, I think I have a pretty good handle on the wiring. My real concern was the triggering signals being dirty. I think I have found a solution tho. According to my website I am going to use a voltage follower op amp. After thinking about this a little bit I have decided to use a PNP...

When you were wiring your MS did you create a whole new harness for the MS system? Or could did you splice most of the lines coming from the stock ECU/PCM? Did you use the existing relay/fuse circuitry or did you create your own seperate "fuse/relay box"? Im starting to plan the actual wiring...

Headed to the junk yard this weekend. Going to pick up GM CLT temp sensor, Air intake sensor and hack apart some unsuspecting wiring harnesses for nice automotive grade connectors. I am going to make a seperate wiring harness for the MS so I am able to go back and forth quite easily from the...

Well I will update this thread with my progress I will also throw my progress on: http://www.squirtingxj.exofire.net/

all of the data from that yahoo group has been moved to tech articles and the megasquirt homepage I believe. As far as implementing MS on the AMC six there is a writeup somewhere online that details the build specifically on that motor (it does make a difference if you use stock ignition...

lol, no it isn't anything like that. . . . Megasquirt is a DIY engine managment system. By installing megasquirt it gives the user full control of the amount of fuel injected and ignition timing. It allows the owner to tune! If you havent been exposed to this do a quick google search and you...

I am in the process of megasquirting my '92 XJ 4.0L. I have done quite a bit of research and am starting on actual build. I am planning on using the stock crank and dizzy signals for ignition on my Megasquirt1-V3 board running MSnS code. I am in the process of documenting all of my progress on a...
