2s2mad 10 Posted October 28, 2020 (edited) Hello, I am looking to upgrade my setup from MS2 V3 Fuel only to MS2 V3 Fuel and Spark. Current setup is (running strong for 8 years now) : MS2 V3board. Map sensor, 240SX TPS (not currently used but connected/available) AEM Wideband Fuel only L28, N/A, Ported and polished head, Turbo injectors, stage 1 Isky cam, walbro. Complete inox Header with 3 inches exhaust system. Triggered from the coil and using the standard distributor for spark. I would like to upgrade my setup and have MS2 control also Spark. This is what I have gathered to achieve this goal : 36-1 trigger wheel fitted to crank pulley 3 wires Hall sensor DIS6-02 igniter from a 300ZX (or similar) Ford coil on plugs (DG-508) My question is : what needs to be done to my MS2 ECU in order to upgrade it to be able to control spark while using a 36-1 trigger wheel (wasted spark). The MS ECU was purchased built to order with a fuel only setup in mind, so the components to control spark would need to be added (hardware, firmware upgrade?). Any pointers, good write-up? Thanks Cheers Simon Edited October 28, 2020 by 2s2mad Quote Share this post Link to post Share on other sites
2s2mad 10 Posted November 4, 2020 (edited) Hi Guys, Just to let you know that I am currently RTFM. I begin to understand what needs to be done (I bought my fisrt resistors!). I will get back to you when I make some progress just in case that helps others. Cheers Edited November 4, 2020 by 2s2mad Quote Share this post Link to post Share on other sites
didier 10 Posted November 7, 2020 Hi, you have to reopen your ecu and be sure your ignition out is wired, and you'll need some IGBT 's to control wasted sparks , with your cops ( are you sure your 300 zx ignitor is useful ? ) read the ms extra manual , every thing is avalaible . with a 36-1trigger wheel , you put 50 degres in the soft TS Quote Share this post Link to post Share on other sites
NewZed 84 Posted November 7, 2020 This might be simpler and faster than a crank-mounted wheel. Several good articles on the web site also. https://www.diyautotune.com/product/54-mm-optical-trigger-wheel-for-nissan-l28et-or-vg30e/ https://www.diyautotune.com/support/tech/hardware/nissan-trigger-disc/ https://www.diyautotune.com/support/ Quote Share this post Link to post Share on other sites
didier 10 Posted November 8, 2020 simpler, yes, but far less acurate, distributorless system is optimum Quote Share this post Link to post Share on other sites
