Flexicoker Posted May 7, 2008 Share Posted May 7, 2008 From DIY Auto Tune: MS230-K $247 Megasquirt-II kit with V3.0 PCB MSStim22-K $45 Stimulator kit MSRelay-K $64 Relay board kit MSRelayCable $70 Megasquirt to relay board cable LC-1 without gauge $199 I'm putting an L28E in my 240z, the engine is complete with injectors, sensors, etc. Other things: Fuel Pump 240sx throttle body (the preferred method of getting a potentiometer TPS?) GM temp sensors random wire, or possible the DIY bundle to connect my engine to the relay board Laptop Serial cable or USB-converter depending on laptop Am I missing anything? I am assuming that the existing MAP sensor will work and that the stock fuel pressure regulator will be ok (and that it still has the stock MAP sensor). I don't plan on doing anything fancy at the moment, just make this thing run reliably and efficiently, but I'd like to have the option of going distributorless, turbo, and flex-fuel in the future. In this article: http://www.diyautotune.com/tech_articles/how_to_megasquirt_your_280zx_turbo.htm They're connecting the stock distributor to the ECU, does this mean the timing on the stock distributor can be adjusted through MS? Or are they using it as an RPM signal? Thanks, Eric Quote Link to comment Share on other sites More sharing options...
mobythevan Posted May 8, 2008 Share Posted May 8, 2008 The MAP sensor is inside the megasquirt box. You just run a vacuum line to it so your covered there. In that article they are using the 82-83 style 280zx turbo dizzy which means you must control the timing with the megasquirt box because that dizzy does not provide any mechaincal timing adjustment. It is made for computer timing control so it works perfect with megasquirt. Quote Link to comment Share on other sites More sharing options...
evildky Posted May 8, 2008 Share Posted May 8, 2008 easy therm allows you to use the stock CHTS but you'll need an IAT the GM one is popular, and as moby pointed out the map sensor is on board for the assymbled kits and there is no stock MAP on the Z's and you can still run the n/a distributor but the wiring and setting will be a bit different Quote Link to comment Share on other sites More sharing options...
Flexicoker Posted May 8, 2008 Author Share Posted May 8, 2008 ah, so does that mean that the MS will not control the N/A dizzy at all? Or can I still control it with a different wiring setup? Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted May 8, 2008 Share Posted May 8, 2008 You would need to lock down the centrifugal advance on the stock distributor if you wanted to use it... Quote Link to comment Share on other sites More sharing options...
