I just reflashed my ms2 with newer vesion: ms2/exta alpha 3.2.0, what do i put under "spark mode" would basic trigger be right, my other version did not have this thanks

i am driving the coil with the ms2's ignition driver, utilizing the stock nissan CAS igntion settings are: rising edge/trigger rise/standard coil charge/going high(inverted) with 10 deg spark map and a 60 deg trigger offset

I have tried adjusting the trigger angle with no effect to timing light results i have Also tried setting entire map to 10 deg adv. with no change. ill try adjusting the trigger angle again with 10 degs on whole map.

I am using v2.90 embedded code,serial signature 2.9050, tunerstudio ms v1.044. I am using this on a m2s kit v3.0 pcb. -thanks matt

i am really confused as how to set the base timing on my car, 240z/vg30et ms2 using tunerstudio stock nissan CAS. my problem is when i check the timing with a light while cranking, while the dizzy is in its normal posistion its at least 40+ degrees too advanced. I have tried changing the trigger angle from 0 to 60 and tried adjusting the spark advance table, no change from either. i have read that your supposed to set a fixed angle so as not use the igntion table but i cannot even find that option in tunerstudio. I am really confused as what steps to take from here.If someone could give me an idea about what i might be doing wrong here, or maybe give me a step by step guide to setting base timing that would really help. Thanks -James

I have a 1971 240z with a 1985 300zx turbo engine that i recently installed a ms2 on. I am using it control both fuel and spark i have gotten it to run but had to open throttle to do it and engine was backfiring and would not idle. I am wondering how to setup the base timing as i believe that is the issue, i already setup req_fuel and tps calibration as well as general specs using tunerstudio I am using the stock distributor with CAS w/6 slots one being different than the others(#1 TDC), Ive been researching how to do this but i cant seem to find the information i need. I have it setup per mobythevan's wiring diagram. to sum it up: do i have to change orientation of distributor from stock?,do i have to change/setup anything in tunerstudio for ignition for it to start so i can start tuning? Since I am new to this forum here is a description of my car 1971 240z vg30et engine Megasquirt 2 ecu 420cc injectors 3 inch exhaust BW t5 5 speed gutted intake plenum holset h1c tial 38mm wastegate walbro 255

the engine is not in the 72 yet but it really pulled hard in my z31 @3050 lbs so in the 240 it should be pretty quick

hey guys swapped the fuel lines and fired up almost immediately, it is so funny how i could be so careful with connecting all of the wiring and do something like hook up the fuel lines backwards, anyways here is a pic and a video. my car the engine is going into.

you must be right, that sounds right, I have never hooked up fuel lines staright from gas tank, when i tried to blow compressed air through the FPR it would go through one way but not the other thanks I will swap the lines next time i work on engine

rails are dry

I am currently learning to Tig weld and I was wondering what gauge pipe you guys would think i should use for a turbo relocation pipe -cheers James

tank and harness are from the 300zx. the stock fuel pump for some reason is not pumping fuel past the regulator

vg30et ran fine a few months ago, sat for a few months.now No fuel to injectors extreme fuel build up between fuel tank and FPR, when i pulled fuel line it was under extreme pressure(wish i would have known) it sprayed everywhere highly atomized fine spray. pulled Fpr, right side rail had barely any fuel, left side none at all, return line none at all. suggestions? I am all ready getting a new FPR, how about cleaning fuel lines without removing injectors? thanks -cheers James

Hello everybody I am currently trying to put a vg30 in my 72. I have the engine from the z31 out of the car with harness attached, the engine ran great before i pulled it out of the car. Now even with everything attahed the engine cranks, fuel pump primes, engine rotates but will not fire. I am just looking for suggestions, as i have been chewking wires for 6 hours with no results. does anybody have any suggestions? -cheers James I left that post 2 days ago I now have ascertained that all plugs are working. heres what I know the fuel rail is basically empty when i pulled regulator off, no fuel out of rail return line, when i pulled the line from fuel pump to regulator it sprayed gasoline everywhere like it was under extreme pressure, also no smell of gas when cranking at all(straight pipe). so I now believe that that the fpr is blocking the fuel from the rail and building extreme pressure between tank and fpr. also fuel pump sounds kinda strained/making strange noises. what do you guys think?, thanks again z31ss - cheers James

thanks for all the info I did find an fsm. I am going to pull a plug and see if it is firing there.

nevermind I found it, does this increase the voltage of the spark?. one more question if i have been cranking the engine over and over without it firing should it smell like gas?(no exhaust equiped) because it doesnt could that mean injectors arent firing?

ok thanks i will try that, sometimes i think it is best to step back think about it. power transistor, is that near the coil?
