I see that there are 2 main versions on the MS&S, the V2.2 and V3. What are most of you running and which is better(from ease of use and intial tuning standpoint)? Is map programming interchangeable between the two? I have my relay board on order but can't decide which version to go with. Any insite/personal experiance would be great. As always, thanks, Brian

I thinking of going with the MS&S, but i'd like to speak with somebody with experiance and could help me decide wich configuaration i want to go with. If you are willing to let me ask a few questions, lend some advice, feel free to give me a call. BTW anyone here near Omaha, NE? Thanks all Brian 402-305-4678

I appreciate the help so far, but its still running like crap. I think it may be running on the start circuit, therefore very rich. It would help alot to speak with sombody who has done this swap before, (and can possibly look at their car while on the phone. If any of you want to, feel free to give me a call anytime on my cell 402-305-4678. I work wierd hours so anytime is fine with me. I'd love the help. thanks again everyone, hopefully its something simple that i'm missing. Brian

i know mine doesn't run well, but it does run. I used a 83 donor and recognize the 8 pin by the ecu end of the harness, but i have a 6 prong over by the FI relay. I'm at work so i don't have my notes as to which wires i used from which plugs.

Thanks again. Earlier i was getting some funny readings with a multimeter, and decided i was going to solder everything instead of using plugs. This should eliminate some problems.( after testing each component first) Can i get rid of the canister,the 2 vacuum solenoids, vacuum rail(for lack of better term) on intake, and the hoses coming from each as long as i put caps over all the nipples? I don't care about emissions, so knowing that what are the minimum sensors this engine needs to run well. Just figure i can eliminate possibilities. Is there any of you that have done the swap and/or installed a MS&S system on your car that would be willing to talk on the phone? Some things are easier that way. As always, thanks a ton for your help. I want my baby back on the road

Thank you very much for responding. I'm completely open to ideas at this point. I was just in the garage. I tried starting the car but all it would do was crank, but sounded like it was trying. Checked for spark (which was there), and could smell i had fuel. I had a friend crank the engine while i worked the flapper on the afm by hand. with it pushed the engine would start to crank but not quite fire, but with a little throttle it started and ran, although very rough, and rich enough to smoke up everything. I tried driving it but it had no power. you could rev it slowly but it sounded rough. i checked the wiring and everything ohms good back to the ECU I pulled the vacuum line off the fuel PSI regulator, sucked on the vacuum line, but nothing changed. BTW, before it started playing with the regulator didn't change anything. However, I pinched the fuel line itself and the idle smoothed out and i could rev the engine closer to normal, but it was still rich. Any more ideas guys? Thanks in advance! sleeperz - i didn't even touch the ignition system when transplanting the engine

again right.... Yes - I've searched and searched but still need to post a question what I've got.. 76 280z 5speed with 83 zxt swap. all emissions are hooked up still i drove the donor car(guy was doing a v8 swap and didn't want the engine) ran great in donor car, pulled the engine without disconnecting any wiring from the engine itself (flipped everything on top and tied it on-really helped when the time came to lay everything out in the 76) put everything together with stock parts and the car runs but... the problem it runs so rich that it floods itself out idling warm or cold, i've checked all the connections, ohmed everything from plug back to the computer and all checks good. everything has proper grounds. no leaks on the intake, but the tube is longer now then stock so it would fit. i'm running the 76 fuel pump, but can't imagine it putting out more psi than the 83 the AFM or computer could have been banged i suppose does it sound like the computer is in "limp" mode? is there some wire that i missed when i spliced the harneses together? can you test the computer itself? what do you think? I've tried the usual stuff(connections, temp sensors, grnds) its killing me that it runs-sortof, and not quite well enough to drive if you run it hard it can almost burn all the fuel but smokes like hell when you let off the throttle. I've pulled the plugs after it idles awhile and they are soaked. should i get a different ECU or AFM, or try one of the 300zx computer conversions(what are the actual advantages to this btw) what is the absolute minimum this engine needs to run well (i don't care about passing smog tests) sorry for the length, but I'm finally asking for help. Its driving me nuts that I can fix a jet (I'm active duty USAF) but not my baby also i tried to limit my questions to things i've searched over and over and couldn't find a good answer for or was still a little confused about. thankyou very much and can't wait for an answer back Brian brian.powers@offutt.af.mil if you want, or have anything that might help(diagrams, charts - I'm open to anything at this point)
