JohnnyWadd Posted October 4, 2014 Report Share Posted October 4, 2014 Getting ready to do this. My goal is good running mpi with coil on plug, cold idle,ability to hook up my cruise servo. I will make this my build thread as a reference for others too.. MPI Manifold have Chad's intake with 75 mm t/b Different t/b for idle control or some other option for idle controll Fuel pressure regulator , still need Injectors and pigtails x4 don't have still need to select size Wideband controller and sensor , have Mgasquirt3 pcb3.57 , still need and that's what was recommended to me for coil on plug Dizzy for cam sensor (need for coil on plug or sequential injector control) still need MKI crank wheel or crank and sensor mount, still need (looking for a crank wheel that can be installed on my underdrive pulley) Coils and brackets. Still need to research that one a little more. Sensors...have the tps for the ford t/b , need I believe an IAT and CTS and MAP? Fuel pump upgrade have Little lost on the map sensor or maybe the MS has a input for pressure? Seems like I need a MAP sensor since I wont have a MAS... MPI I/c piping still need Wiring? Use stock stuff and have Scott put MS in a old ECU or just get the MS and wiring it in? And of course I do have a good running car with the normal starion issues fixed with a big turbo and 3 inch exhaust and big I/c Link to comment Share on other sites More sharing options...
Chad Posted October 4, 2014 Report Share Posted October 4, 2014 use a stock ford 65 mm TB unless you want top end power only, then use a 70. 75 mm will add no real flow benifit, and ruins the tip-in throttle response and makes idle and off idle (slow cruise) tuning very difficult.

psu_Crash Posted October 4, 2014 Report Share Posted October 4, 2014 MS has a MAP sensor in it. The MM dizzy is an easy install. Hit ebay for one. You want GM clt and iat sensors. The Ford TPS works fine. For an idle valve I used a bosch 3 wire PWM valve. Can't remember the p/n but I added a TB spacer to install the valve port. Drilled and tapped it for a 3/4" NPT nipple.

psu_Crash Posted October 4, 2014 Report Share Posted October 4, 2014 IMO if you are going that far you would be better off running a new harness. Diyautotune.com sells a nice one Link to comment Share on other sites More sharing options...
SOTTY Posted October 4, 2014 Report Share Posted October 4, 2014 x2 to the new harness , worth the extra dough outlay . 1 Link to comment Share on other sites More sharing options...

DieHARDmitsu. Posted October 4, 2014 Report Share Posted October 4, 2014 If you go with the MM dizzy, a spacer will be needed. ^^^this guy might be able to help. I have an extra MM dizzy with harness/plug...let me know You can get an upgrade trigger disc to go COP. Scott can definitly guide you with this set up.

psu_Crash Posted October 4, 2014 Report Share Posted October 4, 2014 I also run a MM dizzy and did a write up in the MPI forum a while back. Link to comment Share on other sites More sharing options...

Going coil on plug is still up in the air as of today. I thing wasted sparked might be fine. Have not got to talk to lots of people running cop versus wasted spark. I have not heard back from Scott for a bit. Probably overloaded him with questions. Link to comment Share on other sites More sharing options...
psu_Crash Posted October 4, 2014 Report Share Posted October 4, 2014 You can do everything that you want to do with MS2 also. Just FYI. COP vs Wasted spark makes no difference that I am aware of aside from COP costs a lot more.Sequential injection, on the other hand does make a difference at low engine speeds.

DieHARDmitsu. Posted October 4, 2014 Report Share Posted October 4, 2014 (edited) You can do everything that you want to do with MS2 also. Just FYI. COP vs Wasted spark makes no difference that I am aware of aside from COP costs a lot more.Sequential injection, on the other hand does make a difference at low engine speeds.You can go wasted spark for now then change over to COP. A couple of changes in the software settings and wiring the individual coils would be needed.The wasted spark system is good enough in my opinion. BTW, what power range are you shooting for? Dizzy Spacers are sold out as of right now. need to get some more made up.I'M down for a pair if you make more.

scott87star Posted October 5, 2014 Report Share Posted October 5, 2014 You can run COP in wasted spark mode, that's how I set up my flatty. 1 Link to comment Share on other sites More sharing options...

Okay cool...I am interested in that very much. BTW, what power range are you shooting for?

Funky Phil Posted October 6, 2014 Report Share Posted October 6, 2014 (edited) why COP for 300? Just curious. Edited October 6, 2014 by Funky Phil Link to comment Share on other sites More sharing options...
JohnnyWadd Posted October 6, 2014 Author Report Share Posted October 6, 2014 why COP for 300? Just curious. Just my current goal. Why not go COP at any HP ? I Can always up the boost and upgrade my injectors later. Start small and think big! Link to comment Share on other sites More sharing options...
psu_Crash Posted October 8, 2014 Report Share Posted October 8, 2014 (edited) interested in the mm dizzy spacer too... the upgrade the disk for the mm dizzy wheel, whos got that info. i have only ever run edis on my builds Plug and Play Hi Res wheel for the MM CAS. I've run one for years with zero problem.http://yoshifab.com/store/index.php?_a=viewProd&productId=46 I'll grab some measurements and knock a few spacers out too while I-W restocks Edited October 8, 2014 by psu_Crash Link to comment Share on other sites More sharing options...
scott87star Posted October 8, 2014 Report Share Posted October 8, 2014 DIY also make a nice disk, it emulates a 12-1 trigger wheel with a cam signal so you can easily run either wasted spark or full sequential. http://www.diyautotune.com/catalog/50-mm-optical-trigger-wheel-for-nissan-sr20det-or-ka24de-p-472.html Link to comment Share on other sites More sharing options...

scott87star Posted October 8, 2014 Report Share Posted October 8, 2014 Do note that the yoshi disk has the "crank" pattern on the outer ring while the DIY has it on the inner ring. The Mitsu CAS has the four slot "crank" on the outer like the yoshi, not a big deal to swap wires around but you want to make sure you get it right.

JohnnyWadd Posted October 17, 2014 Author Report Share Posted October 17, 2014 Did either of you gentlemen get any spacers made?Ill take 2 spacers.I'd also be interested in a dizzy spacer. LOL my mpi thread is turning into a group buy. I do need a spacer as well though. scott87star I am ready to buy one of your setups too. Link to comment Share on other sites More sharing options...

992gnt Posted November 13, 2014 Report Share Posted November 13, 2014 Why would you want a 4 bar map sensor, is that a MS thing? That's 58 psi worth of measurement, I'm guessing you'd be doing well to hit half of that. I put a GM 3 bar on my 1g so I could run 30+ psi, but a 2.5 bar is still good for 36 psi. I believe the larger the sensor, the less resolution it has as well. Link to comment Share on other sites More sharing options...
